Definitions
- the present invention relates to uses or methods for the treatment of proliferative pathologies, in particular cancers, using osmium compounds and compositions containing them.
- Platinum complexes are known to have significant antitumor activity. The best known of these is the Latin cisp, which is commonly used for the clinical treatment of many cancers. The resistance of certain cancer cells and the intrinsic toxicity of platinum are some of the problems encountered when using this compound. Since the 1970s, research has intensified to find molecules that can replace cisplatin and in recent years, compounds containing osmium have emerged as an interesting alternative to those containing platinum. Some complexes of osmium have thus already been described as being an alternative for cancer treatments.
- the present invention describes osmium compounds which have particularly advantageous anti-tumor properties. These compounds are organometallic compounds, that is to say they contain at least one covalent carbon-osmium bond. In addition, this C-Os bond is stabilized by another intramolecular nitrogen-osmium (N-Os) bond, the nitrogen atom being an element of the organic moiety bonded to osmium by the carbon atom.
- N-Os nitrogen-osmium
- osmium is therefore part of a cyclic entity and this class of compounds is commonly called by the chemists of the discipline the class of cyclometallic compounds.
- the cyclic entity containing the osmium is called a metallocycle.
- osmium is therefore bound to an organic ligand by both a carbon-osmium covalent bond and a donor-acceptor (acid-Lewis base, or coordination link) nitrogen-osmium bond.
- a donor-acceptor ascid-Lewis base, or coordination link
- the existence of such a metallocycle in an organometallic molecule gives it particular properties in terms of reactivity and thermodynamic stability.
- Various types of carbon atoms (aromatic, benzylic or aliphatic) can be metallated and the nature of the bond between the donor atom (nitrogen) and the carbon atom can be varied in many ways.
- the subject of the present invention is therefore a pharmaceutical composition
- a pharmaceutical composition comprising, in a pharmaceutically acceptable carrier, at least one osmium complex compound of the following general formula:
- L 3 and L 4 which may be identical or different, represent an aromatic ligand or a donor ligand of 2 electrons by a nitrogen, oxygen, phosphorus or sulfur atom, or a halogen atom,
- L 5 and L 6 present or absent simultaneously, identical or different, represent, when present, a donor ligand of 2 electrons by a nitrogen, oxygen, phosphorus or sulfur atom, or a hydrogen atom. 'halogen,
- each of L 3 , L 4 , L 5 and L 6 being covalently bonded to at least one other L 3 , L 4 , L 5 and L 6 ligand, and / or being covalently linked to at least one atom of the metallocycle different from the osmium atom,
- one of L 3 and L 4 is an aromatic ligand.
- L 5 and L 6 may be absent or present. If L 5 is absent, so is L 6 , and vice versa. In all cases, the osmium atom has a coordination number of 6. Thus, L5 and L6 may be absent simultaneously if one of L3 and L4 is an aromatic ligand such as benzene or p-cymene, for example.
- L 3 and L 4 , and L 5 and L 6 when present, are called ancillary ligands. Their main role is to complete the coordination sphere of the osmium atom.
- the presence in the compounds according to the invention of the metallocycle comprising both an Os-N bond and an Os-C bond confers on the complexes according to the invention a significant anti-proliferative activity.
- the term "pharmaceutically acceptable carrier” means substances such as excipients, vehicles, adjuvants, buffers that are conventionally used for the preparation of a medicament, and physiologically acceptable by the subject. The choice of such supports depends essentially on the intended route of administration.
- the pharmaceutically acceptable carrier in which the compounds according to the invention can be employed, as well as its constituents, their amount, the dosage form of the composition, its method of preparation, and its mode of administration may be selected by the a person skilled in the art on the basis of his general knowledge according to the type of composition sought.
- the compounds of the invention may be in the form of pharmaceutically acceptable salts, solvates and / or prodrugs.
- the pro-drugs are variants of the compounds of the invention which can be converted in vivo into compounds of the general formula according to the invention.

- the lower graph shows the volume distribution of each tumor after 3 weeks of treatment.
- the tumors volume of the group treated with 1ODC4 are homogeneous and significantly lower compared to the untreated group which has tumors of more heterogeneous and globally larger volumes.
- Figure 4B shows the slowing of growth of an irinotecan-resistant primary colorectal tumor model from a patient. Each point represents a tumor. The average and error bars are represented for each condition.

Under the same experimental conditions, the equivalent ruthenium compounds have a significant effect from 5 molecules per 10 base pairs.
- the compounds of the invention interact in vitro with the plasmid DNA. Substitution of the ruthenium atom by the osmium atom seems to favor the interaction with DNA for the cases presented here. There is little difference between the ability of ODC2 and ODC3 to interact with DNA in vitro, while 1ODC3 is more cytotoxic. Thus, it is likely that the cytotoxic activity of the compounds of the invention does not depend solely on their ability to interact with the DNA, although this is likely to participate in the process.
- HCT116 cells colonal cancer line
- Actin serves as a reference for the amounts of protein loaded on the gel.
- Figure 6B shows that the compounds ODC2 and ODC3 moderately induce phosphorylation of H2AX. Few differences are visible after treatment of the cells with the equivalent ruthenium compounds (RDC11 and RDC34).

- the amount of DNA released after treatment of cells with 1ODC2 is greater than that induced by RDC11 or by cisplatin.
- FIG 7A shows that the compounds ODC2 and ODC3 induce the formation of oxygen reactive derivatives.
- 1ODC3 induces these radicals very significantly from 4 hours of treatment.
- the compounds of the invention have the capacity to induce the production of oxygen-reactive derivatives, which are molecules having adverse effects on the cell and which are often products of an alteration of cellular metabolism.
- CHOP a marker of activation of the UPR pathway.
- oxygen-reactive derivatives can lead to damage of various kinds, such as DNA breaks or the oxidation of cellular proteins.
- This protein oxidation induces protein misfolding, leading to activation of the unfolded protein response (UPR) pathway.
- UPR unfolded protein response
- Activation of this UPR pathway can lead to arrest of cell proliferation or cell death.
- this signaling pathway is also induced during metabolic stress, such as during an alteration of extracellular glucose levels.
- One of the markers of activation of this UPR pathway is the CHOP transcription factor.
- the mTOR pathway is one of the important intracellular signaling pathways that controls the homeostasis of cellular metabolism.
- One of the recognized markers of this pathway is the phosphorylation of the S6 protein on serines 235 and 236.
- the mTOR pathway is particularly interesting in anticancer therapy. Its inactivation by compounds such as rapamycin promotes the reduction of tumor growth. Phosphorylation of this protein was followed by Western blotting from HCT116 cell extract treated with ODC or RDC.
- Figure 7C shows that the compounds ODC2 and ODC3 reduce the phosphorylation of the S6 protein, indicating that these compounds repress the activity of the mTOR pathway.
- the ODCs are slightly less active than the equivalent RDCs (RDC11 and RDC34).
- the compounds of the invention repress the mTOR pathway. Replacing the ruthenium atom with an osmium atom reduces the activity of the osmium compounds on the mTOR pathway.

Description
METHODES ET COMPOSITIONS POUR LE TRAITEMENT DU CANCER METHODS AND COMPOSITIONS FOR THE TREATMENT OF CANCER
La présente invention concerne des utilisations ou des méthodes pour le traitement de pathologies prolifératives, en particulier des cancers, mettant en œuvre des composés de l'osmium et des compositions les contenant. The present invention relates to uses or methods for the treatment of proliferative pathologies, in particular cancers, using osmium compounds and compositions containing them.
Il est connu que les complexes du platine présentent des activités antitumorales importantes. Le plus connu d'entre eux est le cisp latine, qui est couramment utilisé pour le traitement clinique de nombreux cancers. La résistance de certaines cellules cancéreuses et la toxicité intrinsèque du platine font partie des problèmes rencontrés lors de l'utilisation de ce composé. Depuis les années 70, les recherches s'intensifient pour trouver des molécules susceptibles de se substituer au cisplatine et depuis quelques années des composés contenant de l'osmium sont apparus comme pouvant être une alternative intéressante à ceux qui contiennent du platine. Certains complexes de l'osmium ont ainsi déjà été décrits comme pouvant être une alternative lors de traitements anticancéreux. Platinum complexes are known to have significant antitumor activity. The best known of these is the Latin cisp, which is commonly used for the clinical treatment of many cancers. The resistance of certain cancer cells and the intrinsic toxicity of platinum are some of the problems encountered when using this compound. Since the 1970s, research has intensified to find molecules that can replace cisplatin and in recent years, compounds containing osmium have emerged as an interesting alternative to those containing platinum. Some complexes of osmium have thus already been described as being an alternative for cancer treatments.
Il existe donc un besoin de nouveaux agents anti-cancéreux qui pourraient être une alternative à ceux actuellement utilisés, et avantageusement plus efficaces, et/ou qui présenteraient des effets secondaires indésirables moindres. There is therefore a need for new anti-cancer agents which could be an alternative to those currently used, and advantageously more effective, and / or which would have less undesirable side effects.
La présente invention décrit des composés de l'osmium qui présentent des propriétés anti-tumorales particulièrement intéressantes. Ces composés sont des composés organométalliques, c'est-à-dire qu'ils contiennent au moins une liaison covalente Carbone-osmium. De plus, cette liaison C-Os est stabilisée par une autre liaison intramoléculaire azote-osmium (N-Os), l'atome d'azote étant un élément de la partie organique liée à l'osmium par l'atome de carbone. The present invention describes osmium compounds which have particularly advantageous anti-tumor properties. These compounds are organometallic compounds, that is to say they contain at least one covalent carbon-osmium bond. In addition, this C-Os bond is stabilized by another intramolecular nitrogen-osmium (N-Os) bond, the nitrogen atom being an element of the organic moiety bonded to osmium by the carbon atom.
Dans ce type d'arrangement d'atomes, l'osmium fait donc partie d'une entité cyclique et cette classe de composés est communément appelée par les chimistes de la discipline la classe des composés cyclométallés. L'entité cyclique contenant l'osmium est appelée un métallocycle. Dans un tel métallocycle, l'osmium est donc lié à un ligand organique à la fois par une liaison covalente carbone-osmium et par une liaison de type donneur- accepteur (acide-base de Lewis, ou liaison de coordination) azote-osmium. L'existence d'un tel métallocycle dans une molécule organométallique confère à celle-ci des
propriétés particulières en termes de réactivité et de stabilité thermodynamique. Divers types d'atomes de carbone (aromatiques, benzyliques ou aliphatiques) peuvent être métallés et la nature du lien entre l'atome donneur (l'azote) et l'atome de carbone peut être modifiée de multiples façons. In this type of arrangement of atoms, osmium is therefore part of a cyclic entity and this class of compounds is commonly called by the chemists of the discipline the class of cyclometallic compounds. The cyclic entity containing the osmium is called a metallocycle. In such a metallocycle, osmium is therefore bound to an organic ligand by both a carbon-osmium covalent bond and a donor-acceptor (acid-Lewis base, or coordination link) nitrogen-osmium bond. The existence of such a metallocycle in an organometallic molecule gives it particular properties in terms of reactivity and thermodynamic stability. Various types of carbon atoms (aromatic, benzylic or aliphatic) can be metallated and the nature of the bond between the donor atom (nitrogen) and the carbon atom can be varied in many ways.
Selon un premier aspect, la présente invention a donc pour objet une composition pharmaceutique comprenant, dans un support acceptable sur le plan pharmaceutique, au moins un composé complexe d'osmium de formule générale suivante : According to a first aspect, the subject of the present invention is therefore a pharmaceutical composition comprising, in a pharmaceutically acceptable carrier, at least one osmium complex compound of the following general formula:
dans laquelle : in which :
entre C et N, représentée par une ligne courbe, il existe une succession d'atomes formant, avec C, N et Os représentés sur la formule, un cycle (dit métallocycle) qui est constitué de 5 à 8 atomes, between C and N, represented by a curved line, there exists a succession of atoms forming, with C, N and Os represented on the formula, a ring (said metallocycle) which consists of 5 to 8 atoms,
L3 et L4, identiques ou différents, représentent un ligand aromatique ou un ligand donneur de 2 électrons par un atome d'azote, d'oxygène, de phosphore ou de soufre, ou un atome d'halogène, L 3 and L 4 , which may be identical or different, represent an aromatic ligand or a donor ligand of 2 electrons by a nitrogen, oxygen, phosphorus or sulfur atom, or a halogen atom,
L5 et L6, présents ou absents simultanément, identiques ou différents, représentent, lorsqu'ils sont présents, un ligand donneur de 2 électrons par un atome d'azote, d'oxygène, de phosphore ou de soufre, ou un atome d'halogène, L 5 and L 6 , present or absent simultaneously, identical or different, represent, when present, a donor ligand of 2 electrons by a nitrogen, oxygen, phosphorus or sulfur atom, or a hydrogen atom.

lorsque L5 et L6 sont absents simultanément, un des L3 et L4 est un ligand aromatique. when L 5 and L 6 are absent simultaneously, one of L 3 and L 4 is an aromatic ligand.
L5 et L6 peuvent être absents ou présents. Si L5 est absent, L6 l'est aussi, et réciproquement. Dans tous les cas, l'atome d'osmium a un nombre de coordination de 6. Ainsi, L5 et L6 peuvent être absents simultanément si un des L3 et L4 est un ligand aromatique comme le benzène ou p-cymène, par exemple. L 5 and L 6 may be absent or present. If L 5 is absent, so is L 6 , and vice versa. In all cases, the osmium atom has a coordination number of 6. Thus, L5 and L6 may be absent simultaneously if one of L3 and L4 is an aromatic ligand such as benzene or p-cymene, for example.
L3 et L4, et L5 et L6, lorsqu'ils sont présents, sont dits ligands ancillaires. Leur rôle principal est de compléter la sphère de coordination de l'atome d'osmium.
La présence dans les composés selon l'invention du métallocycle comprenant à la fois une liaison Os-N et une liaison Os-C confère aux complexes selon l'invention une activité anti-proliférative notable. L 3 and L 4 , and L 5 and L 6 , when present, are called ancillary ligands. Their main role is to complete the coordination sphere of the osmium atom. The presence in the compounds according to the invention of the metallocycle comprising both an Os-N bond and an Os-C bond confers on the complexes according to the invention a significant anti-proliferative activity.

Les composés de l'invention présentent un effet antiprolifératif vis-à-vis de cellules tumorales. Ils sont particulièrement utiles pour traiter des cancers par accumulation des cellules tumorales en phase G0/G1, ou G2/M et éventuellement par induction d'apoptose ou d'un autre type de mort cellulaire des cellules tumorales. The compounds of the invention exhibit an antiproliferative effect against tumor cells. They are particularly useful for treating cancers by accumulation of tumor cells in G0 / G1 or G2 / M phase and possibly by inducing apoptosis or another type of cell death of tumor cells.
En effet, sans vouloir se lier à une quelconque théorie de l'invention, les composés de l'invention semblent notamment capables d'accumuler les cellules tumorales en phase G0/G1, ou G2/M et donc en bloquant leur cycle cellulaire, mais semblent également capables de générer leur mort rapidement, en particulier lorsque leur concentration est augmentée, signe d'une toxicité dose-dépendante. Indeed, without wishing to be bound to any theory of the invention, the compounds of the invention appear in particular capable of accumulating tumor cells in G0 / G1 or G2 / M phase and thus by blocking their cell cycle, but also seem capable of generating their death rapidly, especially when their concentration is increased, sign of a dose-dependent toxicity.

La recristallisation de ce solide dans un mélange acétone/pentane (diffusion lente) ou dichlorométhane/pentane provoque la précipitation de cristaux de couleur pourpre (50 mg, 68%) qui sont ensuite lavés au diéthyléther puis séchés sous vide. A solution of ODC 22 (65 mg, 0.092 mmol) containing 1,10-phenanthroline (18.3 mg, 0.092 mmol) in methanol (5 mL) was stirred under reflux for 48 h. After evaporation of the solvents and volatile products, the brown residue is dissolved in 10 mL of CH 2 Cl 2 and then filtered on Al 2 O 3 (10: 0.5 CH 2 Cl 2 / NCMe). The purple fraction is collected and evaporated to dryness. Recrystallization of this solid from a mixture of acetone / pentane (slow diffusion) or dichloromethane / pentane causes the precipitation of purple crystals (50 mg, 68%) which are then washed with diethyl ether and then dried under vacuum.

- Test de prolifération de la Usitée Al 72 avec chaque composé - Proliferation test of Usual Al 72 with each compound
La sélection des anti-cancéreux potentiels est faite, dans un premier temps, sur la lignée A172. L'effet des différents composés dérivés de l'osmium sur la viabilité cellulaire est d'abord déterminé par un test de prolifération en fonction de la concentration en produit. L'activité des composés dérivés de l'Osmium est comparée à celle du cisp latine. L'exposition des cellules A 172 à ces dérivés se traduit par une diminution dose-dépendante de leur prolifération. L'effet dépend donc du complexe organique qui entoure le noyau d'Osmium. La concentration d'inhibition de la croissance de 50% des cellules (IC50) en μΜ est déterminée pour chacun des produits (figure 2A). La figure 2B présente les diagrammes de quelques ODC issus des 3 familles de composés décrits sur la base de leurs familles de ligands. Des composés testés, les ODC 13, 16, 20 et 9 apparaissent comme étant les plus actifs avec une IC50 comprise entre 0,25μΜ et 0,8μΜ. Les dérivés de l'osmium montrant une IC50 trop importante (>25μΜ) ont été éliminés de l'étude biologique. The selection of potential anti-cancer drugs is first made on the A172 line. The effect of the various compounds derived from osmium on cell viability is first determined by a proliferation test as a function of product concentration. The activity of compounds derived from Osmium is compared with that of the Latin cisp. The exposure of A 172 cells to these derivatives results in a dose-dependent decrease in their proliferation. The effect therefore depends on the organic complex that surrounds the Osmium nucleus. The growth inhibition concentration of 50% of the cells (IC50) in μΜ is determined for each of the products (FIG. 2A). Figure 2B shows the diagrams of some ODCs from the 3 families of compounds described on the basis of their families of ligands. Of the compounds tested, the ODCs 13, 16, 20 and 9 appear to be the most active with an IC50 between 0.25μΜ and 0.8μΜ. Osmium derivatives showing too high IC50 (> 25μΜ) were removed from the biological study.

Conclusion : Les données de la figure 2 A montrent que l'ensemble des composés selon l'invention ont une activité anticancéreuse sur les lignées testées. De plus, la substitution du ruthénium par l'osmium ne suffit pas à accroître systématiquement l'activité anticancéreuse des composés selon l'invention sur cette lignée. Il semble donc que le potentiel cytotoxique résulte de l'association du métal et des ligands. Conclusion: The data of FIG. 2A show that all the compounds according to the invention have anticancer activity on the lines tested. In addition, the substitution of ruthenium with osmium is not sufficient to systematically increase the anticancer activity of the compounds according to the invention on this line. It therefore seems that the cytotoxic potential results from the association of metal and ligands.

Sur la base des IC50 obtenues sur la lignée Al 72, les composés les plus actifs sont testés sur un nombre plus important de lignées cancéreuses humaines. On the basis of the IC50s obtained on line Al 72, the most active compounds are tested on a larger number of human cancer lines.
A J-l, les cellules sont ensemencées dans une plaque 96 puits à raison de 5 000 et 40 000 cellules/puits en fonction de la vitesse de prolifération de chaque lignée et incubées à 37°C/5% de C02. A J0, le nombre de cellules est compté dans la plaque contrôle (C)
et les composés à tester sont ajoutés dans les autres plaques selon la gamme de concentrations suivantes : 10~8 ; 10~7 ; 10~6 ; 10~5 ; 10~4 M en quadruplicata. A J+2, les cellules sont fixées 1H à 4°C par ajout de TCA à la concentration finale de 10%. Le taux de prolifération est corrélé à l'évaluation de la quantité de protéines. Une solution de Sulforhodamine B 0.4% dans de l'acide acétique 1% est ajoutée dans chaque puit. Le précipité est resuspendu dans du Trisma Base lOmM et l'absorbance est lue à 515nm. Le taux de croissance cellulaire est corrélé au différentiel du nombre de cellules entre J2 (Ti) et J0 (Tz) selon les formules suivantes : At 11, the cells are seeded in a 96-well plate at 5,000 and 40,000 cells / well as a function of the proliferation rate of each line and incubated at 37 ° C / 5% CO 2. At D0, the number of cells is counted in the control plate (C) and the compounds to be tested are added to the other plates in the following concentration range: 10 ~ 8 ; 10 ~ 7 ; 10 ~ 6 ; 10 ~ 5 ; 10 ~ 4 M in quadruplicate. At D + 2, the cells are fixed at 1 ° C. at 4 ° C. by adding TCA at the final concentration of 10%. The proliferation rate is correlated with the evaluation of the amount of protein. A solution of Sulforhodamine B 0.4% in 1% acetic acid is added to each well. The precipitate is resuspended in 10 mM Trisma Base and the absorbance is read at 515 nm. The cell growth rate is correlated with the cell number difference between J2 (Ti) and J0 (Tz) according to the following formulas:
[(Ti-Tz)/(C-Tz)] X 100 pour les nombres de cellules où Ti>Tz [(Ti-Tz) / (C-Tz)] X 100 for the numbers of cells where Ti> Tz
[(Ti-Tz)/Tz] X 100 pour les nombres de cellules où Ti<Tz [(Ti-Tz) / Tz] X 100 for cell numbers where Ti <Tz
Pour chaque indication étudiée, plusieurs lignées cancéreuses sont testées. Le tableau 2 résume les IC50 en μΜ obtenues pour une lignée de chaque indication. Ces résultats démontrent que la seule présence de l'atome d'Osmium ne suffit pas à induire l'activité cytotoxique puisqu'au sein d'une même lignée, les effets sont très variables d'un composé à un autre : par exemple dans la lignée colorectale HCT116, 1ODC19 et 1OCD13 ont une IC50 >1 micromolaire, alors que les autres composés sont plus actifs avec une IC50 <1 micromolaire. De plus, pour un même composé, les activités sont spécifiques d'une lignée à une autre : par exemple 1ODC19 est plus actif sur les lignées de leucémies HL60 et du sein MCF7 avec une IC50 <1 micromolaire, alors qu'il l'est moins sur les autres lignées avec une IC50 >1 micromolaire. Enfin, la substitution seule du métal de ruthénium par l'osmium en gardant les mêmes ligands (RDC 11 vs ODC2) met en évidence un gain d'activité cytotoxique allant du x2 (lignée PC3) au xlO (lignée MCF7). For each indication studied, several cancer lines are tested. Table 2 summarizes the IC50 μΜ obtained for a line of each indication. These results demonstrate that the mere presence of the Osmium atom is not sufficient to induce the cytotoxic activity since within the same line, the effects are very variable from one compound to another: for example in the Colorectal line HCT116, 1ODC19 and 1OCD13 have an IC50> 1 micromolar, while the other compounds are more active with an IC50 <1 micromolar. In addition, for the same compound, the activities are specific from one line to another: for example, 1COD19 is more active on HL60 leukemia and MCF7 breast lines with an IC50 <1 micromolar, whereas it is more active. less on other lines with an IC50> 1 micromolar. Finally, the substitution of the ruthenium metal with osmium alone, keeping the same ligands (RDC 11 vs ODC2), shows a gain in cytotoxic activity ranging from x2 (PC3 line) to x10 (line MCF7).
Conclusion : Les composés issus de l'invention ont une activité anticancéreuse sur un large panel de lignées cancéreuses humaines. Ce panel offre une vision plus large de l'impact du changement du métal et des ligands associés. Conclusion: The compounds of the invention have anticancer activity on a large panel of human cancer lines. This panel offers a broader view of the impact of metal change and associated ligands.

Exemple 4 : Etude de l'activité anticancéreuse des composés selon l'invention sur tumeur syngénique implantée en sous-cutané EXAMPLE 4 Study of the Anticancer Activity of the Compounds According to the Invention on Syngeneous Tumor Implanted Subcutaneously
L'activité anticancéreuse des composés de l'invention est déterminée par le suivi du ralentissement de la croissance d'une tumeur syngénique induite par l'injection sous- cutanée de cellules 3LL (carcinome de Lewis). The anticancer activity of the compounds of the invention is determined by monitoring the slowing down of the growth of a syngeneic tumor induced by the subcutaneous injection of 3LL cells (Lewis carcinoma).
L'induction des tumeurs est réalisée par l'injection de 120 000 cellules 3LL en suspension dans du DMEM 0,5% Pénicilline/Streptomycine sur le flanc de femelles C57/Black6 âgées de 8 semaines. Après 2 semaines environ, lorsque les tumeurs ont atteints une moyenne de 80mm3, les souris sont randomisées en groupes de 8 animaux et reçoivent soit 30

Figure 4B shows the slowing of growth of an irinotecan-resistant primary colorectal tumor model from a patient. Each point represents a tumor. The average and error bars are represented for each condition. Tumor cells derived from surgical resection were first purified and then amplified in several so-called "passing" nude mice. The tumors were then extracted, homogenized and xenografted in a cohort of nude mice. When the tumors reach a tumor volume of 100 mm 3 , the mice are divided into 3 groups and receive intraperitoneal oxaliplatin (once a week, 25 μι οΐ6 / 1¾) or 1ODC12 (twice a week, 8 μι οΐ6 / 1¾) or a formulation serving as a control. Tumors are measured twice a week. The results show that after 14 days of treatment, the tumors of animals treated with 1ODC12 are 50% lower than the control tumors.

Exemple 5 : Etude de l'interaction des composés selon l'invention avec l'ADN Interaction in vitro entre les composés de l'invention et de l'ADN plasmidique : Example 5 Study of the Interaction of the Compounds According to the Invention with the DNA In Vitro Interaction Between the Compounds of the Invention and the Plasmid DNA
Afin d'approcher le mode d'action des composés issus de l'invention, la capacité de ceux-ci à interagir avec l'ADN a été testé en utilisant de l'ADN plasmidique double brin. Ces expériences ont été menées comparativement aux dérivés de ruthénium équivalent (RDC 11 pour ODC2 et RDC34 pour ODC3). Les composés ont été incubés pendant une nuit à température ambiante avec de l'ADN plasmidique nu avec des ratios molaires de composés pour 10 pairs de bases allant de 1 à 20. Après incubation, les mélanges ont été déposés sur gel d'agarose 1% et mis à migrer dans un champ
électrique jusqu'à séparation des diverses formes de plasmide (superenroulé, coupé, linéaire). L'ADN est alors marqué par de l'éthidium bromide sous lampe UV. L'interaction entre les composés et l'ADN plasmidique entraine un ralentissement de la migration de l'ADN sur gel pouvant être induit par la formation du complexe plus lourd et/ou par l'induction de cassure dans l'ADN plasmidique superenroulé. In order to approach the mode of action of the compounds of the invention, the ability of these compounds to interact with the DNA was tested using double-stranded plasmid DNA. These experiments were conducted compared to ruthenium equivalent derivatives (RDC 11 for ODC2 and RDC34 for ODC3). The compounds were incubated overnight at room temperature with naked plasmid DNA with molar ratios of compounds for 10 base pairs ranging from 1 to 20. After incubation, the mixtures were deposited on 1% agarose gel. and put to migrate in a field until separation of the various plasmid forms (supercoiled, cut, linear). The DNA is then labeled with ethidium bromide under a UV lamp. The interaction between the compounds and the plasmid DNA results in a slowing of the migration of the DNA on gel that can be induced by the formation of the heavier complex and / or by the induction of breakage in the supercoiled plasmid DNA.
La figure 6A montre que les composés ODC2 et ODC3 entraînent un ralentissement de la migration de l'ADN plasmidique dans le gel, indiquant une interaction entre ces composés et l'ADN. Ce ralentissement commence à être significatif avec un ratio de 2.5 molécules d'ODC pour 10 paires de base. Dans les mêmes conditions expérimentales, les composés de ruthénium équivalent ont un effet significatif à partir de 5 molécules pour 10 paires de base. Figure 6A shows that the ODC2 and ODC3 compounds cause a slowdown in the migration of plasmid DNA into the gel, indicating an interaction between these compounds and the DNA. This slowdown begins to be significant with a ratio of 2.5 molecules of ODC to 10 base pairs. Under the same experimental conditions, the equivalent ruthenium compounds have a significant effect from 5 molecules per 10 base pairs.
Conclusion : Les composés de l'invention interagissent in vitro avec l'ADN plasmidique. La substitution de l'atome de ruthénium par l'atome d'osmium semble pour les cas présentés ici favoriser l'interaction avec l'ADN. Il y a peu de différence entre la capacité des composés ODC2 et ODC3 à interagir avec l'ADN in vitro, alors que 1ODC3 est plus cytotoxique. Ainsi, il est probable que l'activité cytotoxique des composés de l'invention ne dépende pas uniquement de leur capacité à interagir avec l'ADN bien que celle-ci participe vraisemblablement au processus. Conclusion: The compounds of the invention interact in vitro with the plasmid DNA. Substitution of the ruthenium atom by the osmium atom seems to favor the interaction with DNA for the cases presented here. There is little difference between the ability of ODC2 and ODC3 to interact with DNA in vitro, while 1ODC3 is more cytotoxic. Thus, it is likely that the cytotoxic activity of the compounds of the invention does not depend solely on their ability to interact with the DNA, although this is likely to participate in the process.
Etude de la phosphorylation de la protéine H2AX, un marqueur de dommage à l'ADN. Study of the phosphorylation of the protein H2AX, a marker of damage to the DNA.
Afin de comprendre les répercussions d'une interaction entre les composés de l'invention et l'ADN, la phosphorylation de la protéine H2AX a été suivie par western blot. La phosphorylation de H2AX est un marqueur reconnu de l'existence de dommages à l'ADN dans une cellule. Des cellules HCT1 16 (lignée de cancer colorectal) ont été traitées avec les divers composés pendant 16h et les protéines ont été extraites, séparées sur gel SDS acrylamide, transférées sur nitrocellulose et identifiées à l'aide d'anticorps spécifiques pour la protéine H2AX phosphorylée et pour l'actine. L'actine sert de référence pour les quantités de protéines chargées sur le gel.
La figure 6B montre que les composés ODC2 et ODC3 induisent modérémment la phosphorylation de H2AX. Peu de différences sont visibles après le traitement des cellules avec les composés ruthénium équivalents (RDC11 et RDC34). In order to understand the repercussions of an interaction between the compounds of the invention and the DNA, the phosphorylation of the H2AX protein was followed by Western blot. Phosphorylation of H2AX is a recognized marker of the existence of DNA damage in a cell. HCT116 cells (colorectal cancer line) were treated with the various compounds for 16 hours and the proteins were extracted, separated on SDS acrylamide gel, transferred to nitrocellulose and identified using specific antibodies for the phosphorylated H2AX protein. and for actin. Actin serves as a reference for the amounts of protein loaded on the gel. Figure 6B shows that the compounds ODC2 and ODC3 moderately induce phosphorylation of H2AX. Few differences are visible after treatment of the cells with the equivalent ruthenium compounds (RDC11 and RDC34).
Conclusion : Les composés de l'invention induisent la phosphorylation de la protéine H2AX, suggérant que ces composés peuvent induire des dommages à l'ADN. La substitution du ruthénium par l'osmium ne semble pas affecté significativement cet activité pour les exemples présentés ici. Conclusion: The compounds of the invention induce phosphorylation of the H2AX protein, suggesting that these compounds can induce DNA damage. The substitution of ruthenium with osmium does not seem to significantly affect this activity for the examples presented here.
Etude de l'induction de dommage à l'ADN dans des cellules cancéreuses traitées avec les composés de l'invention. Study of the induction of damage to DNA in cancer cells treated with the compounds of the invention.
Afin de démontrer la capacité des composés de l'invention à provoquer de dommages à l'ADN des cellules cancéreuses, une approche dite par cornet assay a été entreprise. Cette approche consiste à évaluer l'état de l'ADN génomique des cellules. Les cellules cancéreuses HCT116 ont été traitées pendant une heure avec 1ODC2, le RDC 11 ou le cisplatine (cis) à une concentration de ΙΟμΜ. Après traitement, les cellules sont fixées et placées dans un gel d'agarose mou. L'ensemble est ensuite placé dans un champ électrique. Après une migration de 30 minutes, l'ADN est marqué au propidium ionide. L'ADN endommagé sort du noyau. In order to demonstrate the ability of the compounds of the invention to cause damage to the DNA of cancer cells, a so-called cornet assay approach has been undertaken. This approach consists in evaluating the state of the genomic DNA of the cells. Cancer cells HCT116 were treated for one hour with 1ODC2, RDC 11 or cisplatin (cis) at a concentration of ΙΟμΜ. After treatment, the cells are fixed and placed in a soft agarose gel. The set is then placed in an electric field. After a 30 minute migration, the DNA is labeled with propidium ionide. The damaged DNA comes out of the nucleus.
La figure 6C montre que 1ODC2 augmente très significativement la quantité d'ADN étant sorti du noyau, indiquant la présence de dommages à l'ADN. En outre, la quantité d'ADN sortie après traitement des cellules à 1ODC2 est supérieure à celle induite par le RDC11 ou par le cisplatine. Figure 6C shows that 1ODC2 very significantly increases the amount of DNA out of the nucleus, indicating the presence of DNA damage. In addition, the amount of DNA released after treatment of cells with 1ODC2 is greater than that induced by RDC11 or by cisplatin.
Conclusion : Ces résultats indiquent que les composés de l'invention induisent dans les cellules cancéreuses des dommages à l'ADN. Par ailleurs, le remplacement de l'atome de ruthénium pas l'atome d'osmium modifie les propriétés des composés au regard de leur capacité à interagir avec l'ADN et à induire des dommages à l'ADN. Conclusion: These results indicate that the compounds of the invention induce DNA damage in cancer cells. In addition, the replacement of the ruthenium atom not the osmium atom modifies the properties of the compounds with respect to their ability to interact with DNA and to induce DNA damage.
Exemple 6 : Etude de la régulation de voies de signalisation liées au métabolisme cellulaire Example 6 Study of the Regulation of Signaling Pathways Related to Cellular Metabolism
Analyse de la production de dérivés réactifs à l'oxygène.
Etant donné qu'une des caractéristiques particulières des composés à base d'osmium est leur potentiel rédox, l'effet de ces composés sur la production de dérivés réactifs à l'oxygène a été étudié. En effet, il est possible que les propriétés rédox des composés à base de ruthénium altèrent l'activité d'enzymes de type oxydo-réductase impliquées dans le métabolisme cellulaire, conduisant ainsi à la production de dérivés réactifs à l'oxygène. Pour mesurer la production de ces dérivés réactifs à l'oxygène, une sonde fluorescent (carboxy-H2DCFDA) a été utilisée. Les cellules HCT116 on été traitées à différents temps et différentes concentrations d'ODC avant d'être incubées pour 15 minutes avec la sonde fluoresecente. Le signal a ensuite été quantifié avec un fluorimètre. La ménadione (men) a été utilisée comme témoin positif. Analysis of the production of reactive derivatives with oxygen. Since one of the particular characteristics of osmium-based compounds is their redox potential, the effect of these compounds on the production of oxygen-reactive derivatives has been studied. Indeed, it is possible that the redox properties of ruthenium compounds alter the activity of oxidoreductase enzymes involved in cell metabolism, thus leading to the production of oxygen reactive derivatives. To measure the production of these oxygen-reactive derivatives, a fluorescent probe (carboxy-H2DCFDA) was used. The HCT116 cells were treated at different times and concentrations of ODC before being incubated for 15 minutes with the fluorescent probe. The signal was then quantified with a fluorimeter. Menadione (men) was used as a positive control.
La figure 7A montre que les composés ODC2 et ODC3 induisent la formation de dérivés réactifs à l'oxygène. En particulier, 1ODC3 induit ces radicaux de manière très importante dès 4 heures de traitement. Figure 7A shows that the compounds ODC2 and ODC3 induce the formation of oxygen reactive derivatives. In particular, 1ODC3 induces these radicals very significantly from 4 hours of treatment.
Conclusion: Les composés de l'invention ont la capacité d'induire la production de dérivés réactifs à l'oxygène, qui sont des molécules ayant des effets néfastes sur la cellule et qui sont souvent des produits d'une altération du métabolisme cellulaire. Conclusion: The compounds of the invention have the capacity to induce the production of oxygen-reactive derivatives, which are molecules having adverse effects on the cell and which are often products of an alteration of cellular metabolism.
Analyse de l'expression de CHOP, un marqueur de l'activation de la voie UPR. Expression analysis of CHOP, a marker of activation of the UPR pathway.
La formation de dérivés réactifs à l'oxygène peut conduire à des dommages de divers ordres, tel que des cassures de l'ADN ou l'oxydation de protéines cellulaires. Cette oxydation protéique induit un mauvais repliement des protéines, conduisant ainsi à l'activation de la voie UPR (unfolded protein response). L'activation de cette voie UPR peut conduire à un arrêt de la prolifération cellulaire ou une mort cellulaire. Par ailleurs, cette voie de signalisation est également induite lors de stress métaboliques, tel que lors d'une altération des niveaux de glucose extracellulaire. Un des marqueurs de l'activation de cette voie UPR est le facteur de transcription CHOP. The formation of oxygen-reactive derivatives can lead to damage of various kinds, such as DNA breaks or the oxidation of cellular proteins. This protein oxidation induces protein misfolding, leading to activation of the unfolded protein response (UPR) pathway. Activation of this UPR pathway can lead to arrest of cell proliferation or cell death. Moreover, this signaling pathway is also induced during metabolic stress, such as during an alteration of extracellular glucose levels. One of the markers of activation of this UPR pathway is the CHOP transcription factor.
Afin de connaître les répercussions et/ou l'origine de la production des dérivés réactifs à l'oxygène induits par les ODC, l'expression de CHOP a été analysé par Western blot après traitement des cellules HCT116 avec les composés de l'invention.
La figure 7B montre que 1ODC2 et 1ODC3 (doses entre 2.5 et ΙΟμΜ) induisent tous deux l'expression de CHOP. LODC3 semble être légèrement plus actif. Cependant, le RDC11 et le RDC34 ont un effet plus important sur l'expression de CHOP. In order to know the repercussions and / or the origin of the ODC-induced oxygen reactive derivative production, the expression of CHOP was analyzed by Western blotting after treatment of the HCT116 cells with the compounds of the invention. Figure 7B shows that 1ODC2 and 1ODC3 (doses between 2.5 and ΙΟμΜ) both induce CHOP expression. LODC3 seems to be slightly more active. However, RDC11 and RDC34 have a greater effect on CHOP expression.
Conclusion : Les composés de l'invention induisent CHOP et donc vraisemblablement la voie de l'UPR. Cependant, le remplacement du ruthénium par l'osmium ne semble pas donner un avantage aux composés de l'invention dans l'activation de cette voie. Conclusion: The compounds of the invention induce CHOP and therefore presumably the UPR pathway. However, the replacement of ruthenium with osmium does not seem to give an advantage to the compounds of the invention in the activation of this route.
Analyse de la phosphorylation de la protéine S6, un marqueur de l'activité de la voie mTOR. Analysis of phosphorylation of S6 protein, a marker of mTOR pathway activity.
La formation de dérivés réactifs à l'oxygène étant un indicateur d'une altération du métabolisme cellulaire, une étude de la voie mTOR a été réalisée. En effet, la voie mTOR est une des voies de signalisation intracellulaire importante qui contrôle l'homéostasie du métabolisme cellulaire. Un des marqueurs reconnus de cette voie est la phosphorylation de la protéine S6 sur les sérines 235 et 236. La voie mTOR est particulièrement intéressante dans la thérapie anticancéreuse. Son inactivation par des composés comme la rapamycine favorise la réduction de la croissance tumorale. La phosphorylation de cette protéine a été suivie par Western blot à partir d'extrait de cellules HCT116 traitées aux ODC ou au RDC. The formation of oxygen-reactive derivatives being an indicator of an alteration of cellular metabolism, a study of the mTOR pathway was carried out. Indeed, the mTOR pathway is one of the important intracellular signaling pathways that controls the homeostasis of cellular metabolism. One of the recognized markers of this pathway is the phosphorylation of the S6 protein on serines 235 and 236. The mTOR pathway is particularly interesting in anticancer therapy. Its inactivation by compounds such as rapamycin promotes the reduction of tumor growth. Phosphorylation of this protein was followed by Western blotting from HCT116 cell extract treated with ODC or RDC.
La figure 7C montre que les composés ODC2 et ODC3 réduisent la phosphorylation de la protéine S6, indiquant que ces composés répriment l'activité de la voie mTOR. Cependant il est intéressant de noter que les ODC sont légèrement moins actifs que les RDC équivalents (RDC11 et RDC34). Figure 7C shows that the compounds ODC2 and ODC3 reduce the phosphorylation of the S6 protein, indicating that these compounds repress the activity of the mTOR pathway. However it is interesting to note that the ODCs are slightly less active than the equivalent RDCs (RDC11 and RDC34).
Conclusion : Les composés de l'invention répriment la voie mTOR. Le remplacement de l'atome de ruthénium par un atome d'osmium réduit l'activité des composés à base d'osmium sur la voie mTOR.
Conclusion: The compounds of the invention repress the mTOR pathway. Replacing the ruthenium atom with an osmium atom reduces the activity of the osmium compounds on the mTOR pathway.
