Background

Isocitrate Dehydrogenases (IDH) catalyze the oxidative decarboxylation of isocitrate to 2-oxoglutarate (i.e., α -oxoglutarate) these enzymes belong to two distinct subclasses, one of which utilizes NAD (+) as an electron acceptor and the other utilizes NADP (+) as an electron acceptor.

IDH1 (isocitrate dehydrogenase 1(NADP +), cytosolic) is also known as IDH; IDP; IDCD; IDPC or PICD. the protein encoded by this gene is NADP (+) dependent isocitrate dehydrogenase found in the cytoplasm and peroxisomes. it contains PTS-1 peroxisome targeting signal sequences the presence of this enzyme in peroxisomes indicates an effect on the regeneration of NADPH for reduction in peroxisomes, such as the conversion of 2, 4-dienyl-CoA to 3-enoyl-CoA and on the peroxisomal reaction consuming 2-ketoglutarate, i.e. α -hydroxylation of phytanic acid.

The human IDH1 gene encodes a protein of 414 amino acids. The nucleotide and amino acid sequences of human IDH1 can be found in GenBank entries NM _005896.2 and NP _005887.2, respectively. The nucleotide and amino acid sequence of IDH1 is also described in each of: for example, Kruenttan Kong (Nekruetenko) et al, molecular biology and evolution (mol. biol. Evol.)15: 1674-; gisbrexhlet (Geisbrecht), et al, J.Biol.chem., 274:30527-30533 (1999); wiemann (Wiemann), et al, genome research (genome Res.)11: 422-; MGC project set, genome research 14:2121-2127 (2004); lubeck (lube), et al, submitted (12 months 2008) to UniProt knowledge base; kullmann et al, filed (6.1996) on the EMBL/GenBank/DDBJ database; and Sorbulon (Sjoeblom) et al, Science 314: 268-.

Non-mutant (e.g., wild-type) IDH1 catalyzes the oxidative decarboxylation of isocitrate to α -oxoglutarate, thereby enabling NAD⁺(NADP⁺) Reduction to NADH (NADPH), for example in the following positive reactions: isocitric acid + NAD⁺(NADP⁺)→α-KG+CO₂+NADH(NADPH)+H⁺。

It has been found that mutations in IDH1 present in certain cancer cells contribute to the novel ability of the enzyme to catalyze NADPH-dependent reduction of α -oxoglutarate to R (-) -2-hydroxyglutarate (2 HG). the production of 2HG is thought to promote the formation and progression of cancer (Dange, L (Dang, L) et al, Nature 2009,462: 739-44).

IDH2 (isocitrate dehydrogenase 2(NADP +), mitochondrial) is also known as IDH; an IDP; IDHM; IDPM; ICD-M; or mNADP-IDH. The protein encoded by this gene is NADP (+) dependent isocitrate dehydrogenase found in mitochondria. It plays a role in intermediate metabolism and energy production. Such proteins can bind or interact tightly with the pyruvate dehydrogenase complex. The human IDH2 gene encodes a protein of 452 amino acids. The nucleotide and amino acid sequences of IDH2 can be found in GenBank entries NM _002168.2 and NP _002159.2, respectively. The nucleotide and amino acid sequence of human IDH2 is also described in each of: for example, Ha (Huh) et al, filed (11.1992) on the EMBL/GenBank/DDBJ database; and the MGC project group, genome research 14:2121-2127 (2004).

Non-mutant (e.g., wild-type) IDH2 catalyzes the oxidative decarboxylation of isocitrate to α -ketoglutarate (α -KG), thereby mobilizing NAD⁺(NADP⁺) Reduction to NADH (NADPH), for example in the following positive reactions:

isocitric acid + NAD⁺(NADP⁺)→α-KG+CO₂+NADH(NADPH)+H⁺。

It has been found that mutations in IDH2 present in certain cancer cells contribute to the novel ability of the enzyme to catalyze NADPH-dependent reduction of α -oxoglutarate to R (-) -2-hydroxyglutarate (2 HG). 2HG is not formed by wild-type IDH 2. the production of 2HG is thought to promote cancer formation and progression (dan ge, L et al, nature 2009,462: 739-44).

Thus, inhibition of mutant IDH1 and/or mutant IDH2 and their novel activities is a potential therapeutic treatment against cancer, therefore, there is a continuing need for inhibitors of IDH1 and/or IDH2 mutants that have the novel activity of the α hydroxyl group.

The term "haloalkyl" refers to an alkyl group wherein one or more hydrogen atoms are replaced with a halo group, and includes alkyl moieties wherein all hydrogens have been replaced with halo groups (e.g., perfluoroalkyl groups). The term "arylalkyl" or "aralkyl" refers to an alkyl moiety in which an alkyl hydrogen atom is replaced with an aryl group. Aralkyl includes groups in which more than one hydrogen atom has been replaced by an aryl group. Examples of "arylalkyl" or "aralkyl" groups include benzyl, 2-phenylethyl, 3-phenylpropyl, 9-fluorenyl, benzhydryl, and trityl. The term "alkyl" includes "alkenyl" and "alkynyl".

Examples of alkenyl groups include, but are not limited to, allyl, propenyl, 2-butenyl, 3-hexenyl, and 3-octenyl. One of the double bond carbons may optionally be the point of attachment for the alkenyl substituent.

The term "alkynyl" refers to a straight or branched hydrocarbon chain containing 2 to 12 carbon atoms and characterized by having one or more triple bonds. Examples of alkynyl groups include, but are not limited to, ethynyl, propargyl, and 3-hexynyl. One of the triple bond carbons may optionally be the point of attachment of an alkynyl substituent.

The term "alkoxy" refers to-O-alkyl. The term "haloalkoxy" refers to an alkoxy group in which one or more hydrogen atoms have been replaced with halo, and includes alkoxy moieties in which all hydrogens have been replaced with halo (e.g., perfluoroalkoxy).

Unless otherwise indicated, the term "aryl" refers to a fully aromatic monocyclic, bicyclic or tricyclic hydrocarbon ring system. Examples of aryl moieties are phenyl, naphthyl and anthracenyl. Unless otherwise specified, any ring atom in an aryl group may be substituted with one or more substituents. The term "monocyclic aryl" means a monocyclic, fully aromatic hydrocarbon ring system, optionally substituted with one or more substituents that do not form a fused bicyclic or tricyclic ring.

The term "carbocyclyl" refers to a non-aromatic monocyclic, bicyclic, or tricyclic hydrocarbon ring system. Carbocyclyl groups include fully saturated ring systems (e.g., cycloalkyl) and partially saturated ring systems. Carbocyclyl also includes spiro moieties. Examples of spiro moieties include, but are not limited to, bicyclo [3.1.0] hexyl, spiro [2.2] pentyl, spiro [3.3] heptyl, spiro [2.5] octyl, spiro [3.5] nonyl, spiro [4.5] decyl, and spiro [3.6] decyl.

Bicyclic or tricyclic ring systems in which an aryl group is fused to a carbocyclic group and the point of attachment from the ring system to the rest of the molecule passes through a non-aromatic ring are considered carbocyclic groups (e.g., cycloalkyl). Examples of such carbocyclyl moieties include, but are not limited to, 2, 3-dihydro-1H-indene and 1,2,3, 4-tetrahydronaphthalene.

The term "cycloalkyl" as used herein includes saturated cyclic, bicyclic, tricyclic, or polycyclic hydrocarbon groups having from 3 to 12 carbons.

Examples of heterocyclyl groups include, but are not limited to, tetrahydrofuranyl, tetrahydropyranyl, piperidinyl, morpholinyl, pyrrolinyl, pyrimidinyl, and pyrrolidinyl. Heterocyclyl includes fully saturated ring systems and partially saturated ring systems.

Both bicyclic and tricyclic systems and aromatic and non-aromatic rings containing one or more heteroatoms are considered heterocyclyl or heteroaryl. Bicyclic or tricyclic ring systems in which the aryl or heteroaryl group is fused to a carbocyclic or heterocyclic group and the point of attachment from the ring system to the rest of the molecule passes through the aromatic ring are correspondingly considered as aryl or heteroaryl. Bicyclic or tricyclic ring systems in which the aryl or heteroaryl group is fused to the carbocyclic or heterocyclic group and the point of attachment from the ring system to the rest of the molecule passes through a non-aromatic ring are correspondingly considered carbocyclic (e.g., cycloalkyl) or heterocyclic groups.

Subsequently, depending on the symptoms, the dose or frequency of administration, or both, may be reduced to a level at which the improved condition is maintained when the symptoms have been alleviated to a desired level. However, the subject may require intermittent treatment based on long-term consideration of any recurrence of disease symptoms.

The pharmaceutical composition described above comprising a compound of formula I, Ia, Ib, B, C, Ic, Id, Ie, If, Ig, II, III, IIIa, IIIb, IIIc or IIId or a compound described in any of this example can further comprise another therapeutic agent for the treatment of cancer.

Application method

A method is provided for inhibiting the activity of a mutant IDH1 comprising contacting a subject in need thereof with a compound of formula I, Ia, Ib, B, C, Ic, Id, Ie, If, Ig, II, III, IIIa, IIIb, IIIc or IIId (including tautomers and/or isotopologues thereof), or a compound described in any of this embodiment, or a pharmaceutically acceptable salt thereof in one aspect of this embodiment, the cancer to be treated is characterized by a mutant allele of IDH1, wherein an IDH1 mutation contributes to the enzyme's novel ability to catalyze α -keto acid NADPH-dependent reduction to R (-) -2-hydroxypentanedioic acid in the subject in another aspect of this embodiment, in one aspect of this embodiment, this mutant IDH1 has an R132 mutation, in one aspect of this embodiment, the R X mutation is selected from the group consisting of R132, R132C, R733, R4642, R13242, R1329R 3884, the R132 mutation is in another aspect of this embodiment, the R63132 mutation is another R132, R132132 mutation in another aspect of this embodiment, R9R 132, R9, R132, and R9R 38.

Also provided are methods of treating a cancer characterized by the presence of a mutant allele of IDH1, comprising the steps of: administering to a subject in need thereof (a) a compound of formula I, Ia, Ib, B, C, Ic, Id, Ie, If, Ig, II, III, IIIa, IIIb, IIIc, or IIId, or a compound described in any of this example, or a pharmaceutically acceptable salt thereof; or (b) a pharmaceutical composition comprising (a) and a pharmaceutically acceptable carrier.

In one embodiment, the cancer to be treated is characterized by a mutant allele of IDH1, wherein the IDH1 mutation contributes to the novel ability of the enzyme to catalyze the NADPH-dependent reduction of α -oxoglutarate to R (-) -2-hydroxyglutarate in a patient in one aspect of this embodiment, the IDH1 mutation is a R132X mutation in another aspect of this embodiment, the R132X mutation is selected from the group consisting of R132H, R132C, R132L, R132V, R132S, and R132g.

Without being bound by theory, applicants believe that the mutant allele of IDH1 (where the IDH1 mutation contributes to the novel ability of the enzyme to catalyze the NADPH-dependent reduction of α -oxoglutarate to R (-) -2-hydroxyglutarate), and in particular the R132H mutation of IDH1, characterizes a subset of all types of cancers regardless of their cellular nature or location in vivo.

In one aspect of this embodiment, the efficacy of the cancer treatment is monitored by measuring the level of 2HG in the subject. Typically, the 2HG level is measured prior to treatment, wherein an elevated level indicates that a compound of formula I, Ia, Ib, B, C, Ic, Id, Ie, If, Ig, II, III, IIIa, IIIb, IIIc or IIId, or a compound described in any of the embodiments described herein, is used to treat cancer. Once the elevated level is established, the 2HG level is determined during and/or after the course of terminating treatment to determine efficacy. In certain embodiments, the 2HG level is determined only during and/or after the course of terminating treatment. A decrease in 2HG levels during the course of treatment and after treatment is indicative of efficacy. Similarly, a determination that the level of 2HG is not elevated during the course of treatment or after treatment is also indicative of efficacy. Typically, these 2HG measurements will be employed with other well-known assays of efficacy of cancer treatment, such as a reduction in the number and size of tumors and/or other cancer-related lesions, an improvement in the general health of the subject, and other biomarker changes associated with efficacy of cancer treatment.

The 2HG in the sample may be detected by LC/MS. The sample was mixed with methanol at 80:20 and centrifuged at 3,000rpm for 20 minutes at 4 ℃. The resulting supernatant can be collected and stored at-80 ℃ before LC-MS/MS to assess 2-hydroxyglutarate levels. A variety of different Liquid Chromatography (LC) separation methods may be used. Each method can be coupled by negative electrospray ionization (ESI, -3.0kV) to a triple quadrupole mass spectrometer operating in multi-reaction monitoring (MRM) mode, in which MS parameters are optimized with respect to the infused metabolite standard solution. Metabolites can be isolated by reverse phase chromatography using 10mM tributylamine as the ion-pair reagent in an aqueous mobile phase according to a variant of the previously reported method (Roo et al, J.chromatographie. A. section A. 1147,153-64, 2007). One method allows the resolution of TCA metabolites: t is 0, 50% B; t is 5, 95% B; t is 7, 95% B; t-8, 0% B, where B refers to 100% methanol in organic mobile phase. Another method is specific for 2-hydroxyglutarate, running a rapid linear gradient from 50% to 95% B (buffer as defined above) over 5 minutes. As mentioned above, Synergi Hydro-RP, 100 mm. times.2 mm,a particle size of 2.1 μm (Phenomonex) was used as column. Metabolites can be quantified by comparing peak areas to pure metabolite standards of known concentration. Can be prepared from, for example, Misger (Munger) et al Nature Biotech (Nat Biotechnol)26,1179-86,2008¹³C-Glutamine was subjected to metabolic flux studies.

In one embodiment, 2HG is directly evaluated.

In another embodiment, derivatives of 2HG formed during the performance of the assay method are assessed. By way of example, such a derivative may be a derivative formed in an MS analysis. Derivatives may include salt adducts (e.g., Na adducts), hydrated variants, or hydrated variants that are also salt adducts (e.g., Na adducts), e.g., as formed in MS assays.

In another embodiment, metabolic derivatives of 2HG are evaluated. Examples include materials that accumulate or increase or decrease due to the presence of 2HG, such as glutarates or glutamates associated with 2HG, e.g., R-2 HG.

Exemplary 2HG derivatives include dehydrated derivatives, such as the compounds provided below or their salt adducts:

and

in one embodiment, the cancer is a tumor in which at least 30%, 40%, 50%, 60%, 70%, 80% or 90% of the tumor cells carry an IDH1 mutation, and in particular an IDH1R132H or R132C mutation, at the time of diagnosis or treatment.

This may be achieved by methods common in the art, such as DNA sequencing, immunoassay and/or assessing the presence, distribution or level of 2 HG.

Combination therapy

In some embodiments, the methods described herein comprise the additional step of co-administering to a subject in need thereof a second therapy, e.g., an additional cancer therapeutic or an additional cancer treatment. Exemplary additional cancer therapeutic agents include, for example, chemotherapy, targeted therapy, antibody therapy, immunotherapy, and hormone therapy. Additional cancer treatments include, for example: surgery and radiation therapy. Examples of each of these treatments are provided below.

The term "co-administration" as used herein with respect to a further cancer therapeutic means that the further cancer therapeutic may be administered with a compound of one aspect of the invention in a portion of a single dosage form (e.g., a composition of one aspect of the invention comprising a compound of one aspect of the invention and a second therapeutic as described above) or in separate multiple dosage forms. Alternatively, the additional cancer therapeutic agent may be administered prior to, sequentially with, or after administration of the compound of one aspect of the invention. In such combination therapy treatment, the compound of one aspect of the invention and the one or more second therapeutic agents are both administered by conventional methods. Administration of a composition of one aspect of the invention comprising both a compound of one aspect of the invention and a second therapeutic agent to a subject does not preclude administration of the same therapeutic agent, any other second therapeutic agent, or any compound of one aspect of the invention alone to the subject at another time during the course of treatment. The term "co-administration" as used herein with respect to an additional cancer treatment means that the additional cancer treatment may occur prior to, sequentially with, concurrently with, or after administration of a compound of one aspect of the invention.

In some embodiments, the additional cancer therapeutic agent is a chemotherapeutic agent. Examples of chemotherapeutic agents for cancer therapy include, for example, antimetabolites (e.g., folic acid, purine, and pyrimidine derivatives), alkylating agents (e.g., nitrogen mustards, nitrosoureas, platinum, alkyl sulfonates, hydrazine, triazenes, aziridines, spindle poisons, cytotoxic agents, topoisomerase inhibitors, and the like), and hypomethylating agents (e.g., decitabine (5-aza-deoxycytidine), zebularine (zebularine), isothiocyanates, azacytidine (5-azacytidine), 5-fluoro-2' -deoxycytidine, 5, 6-dihydro-5-azacytidine, and the like). Exemplary agents include doxorubicin, actinomycin, alitretinol, altretamine, aminopterin, aminolevulinic acid, amrubicin, amsacrine, anagrelide, arsenic trioxide, asparaginase, atrasentan, belotecan, bepotrotene, bendamustine, bleomycin, bortezomib, busulfan, camptothecin, capecitabine, carboplatin, carboquinone, carmofur, carmustine, celecoxib, chlorambucil, nitrogen mustard, cisplatin, cladribine, clofarabine, clinitase, cyclophosphamide, cytarabine, dacarbazine, dactinomycin, daunomycin, decitabine, colchicine, docetaxel, doxorubicin, ethacryloxide, elimotocel, ethacrycin, enocitabine, epirubicin, estramustine, etoposide, floxuridine, fludarabine, FU (5FU), fluorouracil, Fotemustine, gemcitabine, Grignard implants (Gliadel implant), hydroxyurea, idamycin, ifosfamide, irinotecan, iloufen, ixabepilone, larotaxel, leucovorin, liposomal doxorubicin, liposomal daunomycin, lonidamine, lomustine, methioninone, gansulvan, maxolone, melphalan, mercaptopurine, sodium mercaptoethanesulfonate, methotrexate, methyl aminoacetonate, dibromomannitol, mitoguazone, mitotane, mitomycin, mitoxantrone, nedaplatin, nimustine, orimoemerson, omastatin, otaxel, oxaliplatin, paclitaxel, pemetrexed, pentastatin, pirrubicin, picoxystrobin, porphine sodium, poultitussine, procarbazine, rivastigmine, ranitidine, irinotecan, bixib, Sapatitabine, semustine, adenoviral vector niche gene injection (sitemaradonovec), sarutaplatin (stratapidin), streptozocin, talaporfin, tegafur-uracil, temoporfin, temozolomide, teniposide, tesetaxel, testolactone, tetranitrate, thiotepa, thiazolelline, thioguanine, tipifarnine, topotecan, trabectedin, triimiquinone, trittamine, teriratine, tretinoin, trooshusuofane, trofosfamide, uramustine, vatuofin, vinblastine, vincristine, vindesine, vinflunine, vinorelbine, vorinostat, levoflexixin, and other cytostatics or cytotoxic agents described herein.

Because some drugs work better together than individually, two or more drugs are usually administered simultaneously. Typically, two or more chemotherapeutic agents are used as a combination chemotherapy.

In some embodiments, the additional cancer therapeutic agent is a differentiating agent. Such differentiating agents include retinoids (e.g., all trans-retinoic acid (ATRA), 9-cis-retinoic acid, 13-cis-retinoic acid (13-cRA), and 4-hydroxy-phenyl-retinoic acid amide (4-HPR)); arsenic trioxide; histone deacetylase inhibitors HDACs (such as azacytidine (Vidaza) and butyrate (e.g., sodium phenylbutyrate)); mixed polar compounds (e.g., hexamethylene-bis-acetamide ((HMBA)); vitamin D; and cytokines (e.g., colony stimulating factors, including G-CSF and GM-CSF, and interferon).

In some embodiments, the additional cancer therapeutic agent is a targeted therapy agent. Targeted therapy constitutes the use of agents specific for dysregulated proteins directed against cancer cells. Small molecule targeted therapy drugs are often inhibitors of the enzyme domain of mutated, overexpressed, or otherwise critical proteins within cancer cells. Prominent examples are tyrosine kinase inhibitors such as axitinib, bosutinib, cediranib, dasatinib, erlotinib, imatinib, gefitinib, lapatinib, lestatinib, nilotinib, semaxanib, sorafenib, sunitinib and vandetanib; and cyclin-dependent kinase inhibitors such as axidizib and celecoxib. Monoclonal antibody therapy is another strategy, in which the therapeutic agent is specifically bound to cancer cellsAn antibody to a protein on a surface. Examples include the anti-HER 2/neu antibody trastuzumab that is typically used for breast cancer

And the anti-CD 20 antibodies rituximab and tositumomab, which are typically used for a variety of B-cell malignancies. Other exemplary antibodies include cetuximab, panitumumab, trastuzumab, alemtuzumab, bevacizumab, edrecolomab, and gemtuzumab. Exemplary fusion proteins include aflibercept and dinil. In some embodiments, targeted therapy may be used in combination with a compound described herein (e.g., a biguanide, such as metformin or phenformin, preferably phenformin).

Targeted therapies may also involve small peptides as "homing devices", which may bind to cell surface receptors or the infected extracellular matrix surrounding the tumor. Radionuclides attached to these peptides (e.g., RGD) eventually kill cancer cells if the nuclide decays near the cell. One example of such a therapy includes

In some embodiments, the additional cancer therapeutic agent is an immunotherapy agent. Cancer immunotherapy refers to a diverse set of therapeutic strategies designed to induce the subject's own immune system against tumors. Contemporary methods for generating an immune response against tumors include intravesicular BCG immunotherapy for superficial bladder cancer and the use of interferons and other cytokines to induce an immune response in renal cell carcinoma and melanoma subjects.

Allogeneic hematopoietic stem cell transplantation can be considered a form of immunotherapy, as the immune cells of the donor will typically attack the tumor with a graft-versus-tumor effect. In some embodiments, an immunotherapy agent may be used in combination with one of the compounds or compositions described herein.

In some embodiments, the additional cancer therapeutic agent is a hormone therapy agent. The growth of some cancers can be inhibited by providing or blocking certain hormones. Common examples of hormone sensitive tumors include certain types of breast and prostate cancer. Removal or blockade of estrogen or testosterone is often an important additional treatment. In certain cancers, administration of a hormonal agonist (e.g., a progestin) may be therapeutically beneficial. In some embodiments, a hormone therapy agent can be used in combination with one of the compounds or compositions described herein.

Other possible additional therapeutic modalities include imatinib, gene therapy, peptide and dendritic cell vaccines, synthetic chlorotoxin, and radiolabeled drugs and antibodies.
