Definitions

  • the present invention relates to ⁇ -aza- ⁇ -carboline derivatives, to their preparation and to their therapeutic application.
  • ⁇ -aza- ⁇ -carbolines are defined by derivatives of 1,7 diaza carbazole or 8-aza- ⁇ -carboline; in official nomenclature the name of this tricyclic unit is 9H-pyrrolo [2,3-b: 5,4-c '] dipyridine.
  • the present invention relates to compounds acting on protein kinases such as for example: CHK1, CDK1, CDK2, dyrk2, Flt3, GSK3 beta, MNK2, PDGFR beta, PI3K, PIM1, PIM2, PIM3, PLK, TrkB, all of which are involved in the cancer development. More particularly, the present invention relates to compounds acting on a target called Pim involved in the development of cancers.
  • Pim kinases encompassing Pim-1, Pim-2 and Pim-3, form a distinct family of serine / threonine kinases, and play a functional role in cell growth, differentiation and apoptosis.
  • One of the mechanisms by which Pim kinases can increase cancer cell survival and promote cancer progression is through the modulation of ADB activity, a key regulator of apoptosis.
  • Pim kinases are highly homologous to each other and display similar oncogenic behavior.
  • Pim kinases particularly Pim-1 and Pim-2, have been found to be abnormally expressed in a large number of hematological malignancies.
  • Amson et al. report the overexpression of Pim-1 in acute myeloid leukemia and acute lymphoid leukemia, and that overexpression of Pim-1 appears to result from inappropriate activation in various leukemias (Proc Natl Acad ScL, Vol 86, 8857-8861 (1989)).
  • Studies have demonstrated overexpression of Pim-1 in primary and metastatic CNS lymphoma, an aggressive form of non-Hodgkin lymphoma (Rubenstein et al., Blood, Vol 107, 9, 3716-3723 (2006)). ). Höttmann et al.
  • Pim-2 in B-cell chronic lymphocytic leukemia and suggest that upregulation of Pim-2 may be associated with a more aggressive course of the disease (Leukemia, 20, 1774- 1782 ( 2006)).
  • Abnormal expression of Pim-1 and Pim-2 has been linked to multiple myeloma (Claudio et al., Blood, v. 100, No. 6, 2175-2186 (2002)).
  • Pim-1 Hypermutation of Pim-1 has been identified in diffuse large cell lymphoma (Pasqualucci et al., Nature, Vol 412, 2001, pp 341-346 (2001)) and in Hodgkin's lymphoma classical and nodular predominantly lymphocytic (Liso et al., Blood, Vol.108, No. 3, 1013-1020 (2006)).
  • Pim-1 and Pim-2 have been implicated in prostate cancer (Chen et al., Mol Cancer Res, 3 (8) 443-451 (2005)).
  • Valdman et al. have demonstrated upregulation of Pim-1 in patients with prostate carcinoma and in high-grade prostatic intraepithelial neoplasia (precancerous lesions) (The Prostate, (60) 367-371 (2004) ), while Dai et al.
  • Pim-2 overexpression of Pim-2 in prostate cancer is associated with more aggressive clinical features (The Prostate, 65: 276-286 (2005)).
  • Xie et al. found that 44 kDa Pim-1 (Pim-IL) was significantly upregulated in human prostate tumor specimens, and indicate that Pim-IL has an anti-apoptotic effect on prostate cancer cells in response to chemotherapeutic drugs (Oncogene, 25, 70-78 (2006)).
  • Pim-2 is linked to the perineural invasion (PNI), during which cancer cells curl around the nerves, which are often found in certain cancers such as cancers of the prostate, pancreas, ducts biliary and head and neck (Ayala et al., Cancer Research, 64, 6082 - 6090 (2004)).
  • PNI perineural invasion
  • Pim-3 is aberrantly expressed in human and mouse hepatocarcinomas and human pancreatic cancer tissues (Cancer Res 66 (13), 6741-6747 (2006)).
  • Aberrant expression of Pim-3 has also been observed in gastric adenoma and metastatic sites of gastric carcinoma (Zheng et al., J Cancer Res Clin Oncol, 134: 481-488 (2008)).
  • Pim kinase inhibitors are useful for the treatment of cancer, including leukemias, lymphomas, myelomas, and various solid tumors, including head and neck cancers, colon cancer, prostate cancer, pancreatic cancer, liver cancer and oral cancer, for example. Since cancer remains a disease for which existing therapies are inadequate, it is clearly necessary to identify new inhibitors of Pim kinases that are effective in the treatment of cancer.

  • the dilution solvents are: dimethylsulfoxide; methanol; acetonitrile; dichloromethane.
  • the reaction medium is hydrolyzed with 120 ml of a solution of 10% ammonium chloride and 30 ml of water. It is extracted twice with 50 ml of ethyl acetate and then dried over sodium sulfate, filtered and concentrated to dryness under reduced pressure. 3.2 g of a crude product are obtained which is purified by chromatography on silica gel using a gradient of heptane and ethyl acetate eluent (from 100/0 to 70/30 by volume), 1.7 (63%) g of 5-chloro 4-trimethylstannyl-2- (3'-pyridinyl) pyridine 2.

  • the crude product is purified by chromatography on silica gel using a gradient of eluent of ethyl acetate and methanol or of dichloromethane and methanol (100/0 to 90/10 by volume).
  • the coupled products 4a-h are obtained in yields of between 40 and 75%.
  • This catalyst solution is added to the solution of 3 as well as 7 to 12 mmol of potassium tert-butoxide. It is heated overnight at 100 ° C. After cooling, 10 ml of methanol and 150 ml of ethyl acetate are added. The organic phase is washed with an aqueous solution of sodium bicarbonate, dried and evaporated. The crude product is purified by chromatography on silica gel using a gradient of eluents of ethyl acetate and methanol or of dichloromethane and methanol (from 100/0 to 90/10 by volume). The cyclized products 5a-h are detailed in Table 1 (yield between 35 and 80% depending on the substrates).
  • the cyclization can also be carried out using another catalytic system, in this case the product 4 (1 mmol) is loaded into a 5 ml microwave tube with 0.05 mmol of tris (dibenzylideneacetone) dipalladium (0), 0.11 mmol of 2-dicyclohexylphosphino-2- (N, N-dimethylamino) biphenyl and 1.5 mmol of potassium fert-butoxide. The tube is sealed and then placed under an argon atmosphere, then 4 mL of 1,4-dioxane is added. The mixture is heated in the microwave for 1 hour at 150 ° C. The treatment and the purification of the compound 5 are carried out as described above. The yields are generally lower than those obtained with the Pd (OAc) 2 / Josiphos system. All the steps of this sequence can be carried out either by heating in the microwave (between 110 and 150 0 C) or conventional heating (reflux).
