DICAMENTS
La présente invention concerne de nouveaux composés chimiques, particulièrement de nouveaux produits biaryl-aromatiques, des compositions les contenant, et leur utilisation comme médicaments.
Plus particulièrement, l'invention concerne, selon un premier aspect, de nouveaux produits biaryl-aromatiques présentant une activité anticancéreuse, et en particulier une activité inhibitrice de polymérisation de la tubuline.

Ce composé est décrit comme présentant des propriétés anticancéreuses.
Cette demande de brevet revendique une très grande variété de produits différents, sans toutefois démontrer une quelconque activité sur le domaine revendiqué.
De manière surprenante, ïl a été trouvé qu'il n'est pas possible d'obtenir des produits présentant une activité inhibitrice de polymérisation de tubuline significative avec certains produits inclus dans la formule générale revendiquée dans cette demande WO 02/08190. Cela est d'autant plus gênant que les produits inefficaces qui ont été préparés présentent une structure chimique très proche du seul exemple efficace présenté, de sorte qu'il n'est pas possible de prévoir, a priori, quelles sont les conditions pour obtenir un produit actif (Tableau 2, infra).
Contre toute attente, il a été trouvé de nouveaux produits biaryl-aromatiques, inhibiteurs de polymérisation de la tubuline, possédant également une activité
significative à l'encontre de la prolifération de cellules HCT 116. Ces produits répondent à la formule (I) suivante : BIARYL AROMATIC PRODUCTS, COMPOSITIONS CONTAINERS AND USE AS

DRUGS
The present invention relates to novel chemical compounds, especially new biaryl-aromatic products, compositions containing them, and their use as medicines.
More particularly, the invention relates, in a first aspect, to new biaryl-aromatic products with anticancer activity, and in particular inhibitory activity of tubulin polymerization.
A biaryl-aromatic compound is known from the patent application WO

This compound is described as having anti-cancer properties.
This patent application claims a very wide variety of products different, without demonstrating any activity on the domain claims.
Surprisingly, it has been found that it is not possible to obtain products with inhibitory activity of tubulin polymerization significant with some products included in the general formula claimed in this application WO 02/08190. This is all the more that the inefficient products that have been chemical structure very close to the only effective example presented, so that it is not possible to predict, a priori, what are the conditions for obtain an active product (Table 2, infra).
Against all odds, new biaryl aromatic products have been found, inhibitors of tubulin polymerization, also having an activity significantly against the proliferation of HCT 116 cells.

Evaluation de l'inhibition de polymérisation de tubuline La tubuline est purifiée à partir de cerveaux de porc selon des méthodes publiées (Shelanski et al., 1973, Proc. Nati. Acad. Sci.USA, 70, 765-768.
Weingarten et al., 1975, Proc. Nati. Acad. Sci.USA, 72, 1858-1862).
Brièvement, les cerveaux sont broyés et centrifugés dans un tampon d'extraction. La tubuline, contenue dans le surnageant de l'extrait subit deux cycles successifs de polymérisation à 37 C et dépolymérisation à 4 C, avant d'être séparée des MAPs (Microtubule Associated Proteins) par chromatographie sur colonne de phosphocellulose P11 (Whatman).

A product according to the invention may be useful for inhibiting the polymerization of tubulin in vitro.
Evaluation of Tubulin Polymerization Inhibition Tubulin is purified from pork brains using methods published (Shelanski et al., 1973, Proc Natl Acad Sci USA, 70, 765-768.
Weingarten et al., 1975, Proc. Nati. Acad. Sci. USA, 72, 1858-1862).
Briefly, the brains are crushed and centrifuged in a buffer extraction. The tubulin, contained in the supernatant of the extract undergoes two successive cycles of polymerization at 37 ° C. and depolymerization at 4 ° C., before to be separated from MAPs (Microtubule Associated Proteins) by P11 phosphocellulose column chromatography (Whatman). The Tubulin, thus isolated, is more than 95% pure. It is kept in a buffer named RB / 2 30% glycerol, whose composition is MES-NaOH
13 [acide 2-(N-morpholino)-éthanesulfonique] 50 mM, pH6.8; MgCI2 0.25 mM;
EGTA 0.5 mM; glycérol 30 % (v/v), GTP (guanosine-5'-tri-phosphate) 0.2 mM.
La polymérisation de la tubuline en microtubules est suivie par turbidimétrie comme suit : la tubuline est ajustée à une concentration de 10 pM (1 mg/ml) dans le tampon RB/2 30 % glycérol auquel on ajoute 1 mM GTP et 6mM
MgCI2. La polymérisation est déclenchée par une augmentation de la température de 6 C à 37 C dans une cuve de 1 cm de trajet optique, placée dans un spectrophotomètre UVIKON 931 (Kontron) équipé d'un porte cuve thermostaté. L'augmentation de la turbidité de la solution est suivie à 350 nm.
Les produits sont mis en solution à 10 mM dans le DMSO et ajoutés à des concentrations variables (0.5 à 10 pM) à la solution de tubuline avant polymérisation. La C150 est définie comme la concentration de produit qui inhibe de 50 % la vitesse de polymérisation. On considère comme très actif un produit dont la C150 est inférieure ou égale à 25 pM.
Un produit conforme à l'invention pourra être utile pour inhiber la prolifération de cellules tumorales in vitro.
Test permettant de déterminer l'inhibition de prolifération de la lignée tumorale humaine de colon HCT116 On évalue la prolifération des cellules HCT116 en mesurant l'incorporation de [14C]-thymidine de la façon suivante. Les cellules HCT116 (issues de l'ATCC) sont cultivées dans un milieu DMEM (Gibco) qui contient 10 % de sérum de veau fostal et des antibiotiques (pénicilline 1 /a, streptomycine 1%). Pour effectuer le test de prolifération, on ensemence les cellules dans des microplaques cytostar 96 puits (Amersham), à raison de 5000 cellules par puits. On ajoute ensuite la [14C]-thymidine (0.1 pCi/puits) et les produits à
évaluer. On utilise des concentrations variables de produits jusqu'à 10 pM ;
le DMSO (solvant utilisé pour solubiliser les produits) ne doit pas excéder 0.5 %
dans le milieu. 48 heures après incubation à 37 C, on mesure la radioactivité
incorporée dans les cellules par comptage de la plaque dans un compteur TRI-LUX (Wallac). La C150 est définie comme la concentration de produit qui diminue de 50 % la radioactivité par rapport à un contrôle non traité. On considère qu'un produit dont la C150 est inférieure à 3 pM est cytotoxique 13 [2- (N-morpholino) -ethanesulfonic acid] 50 mM, pH 6.8; 0.25 mM MgCl 2;
0.5 mM EGTA; glycerol 30% (v / v), GTP (guanosine-5'-tri-phosphate) 0.2 mM.
The polymerization of tubulin into microtubules is followed by turbidimetry as follows: tubulin is adjusted to a concentration of 10 μM (1 mg / ml) in 30% glycerol RB / 2 buffer to which 1 mM GTP and 6 mM are added MgCl2. Polymerization is triggered by an increase in the temperature of 6 C to 37 C in a vessel of 1 cm optical path, placed in a UVIKON 931 spectrophotometer (Kontron) equipped with a tank holder thermostatically controlled. The increase in the turbidity of the solution is followed at 350 nm.
The products are dissolved in 10 mM in DMSO and added to variable concentrations (0.5 to 10 μM) to the tubulin solution before polymerization. C150 is defined as the concentration of product that inhibits by 50% the rate of polymerization. We consider very active a product whose IC50 is less than or equal to 25 μM.
A product according to the invention may be useful for inhibiting the proliferation of tumor cells in vitro.
Test for determining the inhibition of proliferation of the line human tumor of colon HCT116 The proliferation of HCT116 cells is evaluated by measuring the incorporation of [14C] -thymidine as follows. HCT116 cells (from the ATCC) are cultured in DMEM (Gibco) medium which contains 10% of serum fetal calf and antibiotics (penicillin 1 / a, streptomycin 1%). For carry out the proliferation test, the cells are seeded in 96-well cytostar microplates (Amersham), at a rate of 5000 cells per well. [14C] -thymidine (0.1 μCi / well) and the products to be added are then added.
assess. Variable concentrations of products up to 10 μM are used;
the DMSO (solvent used to solubilize products) must not exceed 0.5%
in the middle. 48 hours after incubation at 37 ° C., the radioactivity is measured incorporated in the cells by counting the plate in a counter TRI-LUX (Wallac). C150 is defined as the concentration of product that reduces radioactivity by 50% compared to an untreated control. We considers that a product whose IC50 is less than 3 μM is cytotoxic
