Technical field

The present invention relates to medicinal chemistry, and in particular to PIM kinase inhibitors, methods for their preparation and their use in pharmacy.

Background technique

PIM kinases are three homologous serine/threonine kinases belonging to the family of calmodulin-dependent protein kinases (CAMK). Studies have shown that PIM kinase is widely expressed in hematopoietic tissues (J. Biol. Chem., 280, 14168-14176, 2005; Blood, 105, 4477-4483, 2005) and plays an important role in cell survival and proliferation. And overexpressed in human cancer tumors as well as in inflammatory conditions (J. Exp. Med., 201, 259-266, 2005; Biochem. Soc. Trans., 32, 315-319, 2004). Therefore, PIM kinase is increasingly being used to study targets for the treatment of tumors and immunomodulatory drugs. The PIM-1 (Provirus Integration of Maloney 1) gene is a site for frequent insertion of provirus in Moloney murine leukemia virus-induced T cell lymphoma, and PIM-1 kinase is also named (Cell, 37, 141-150, 1984). It was later found that the gene encoding PIM-2 (Provirus Integration of Maloney 2) also had the same weakness (J. Clin. Invest., 115, 2679-2688, 2005). PIM-3 was originally named KID-1 (Kinase Induced by Depolarization 1) and was later renamed for its highly consistent protein sequence with PIM-1 (71% amino acid repeat) (Nature, 428, 332-337, 2005; Cell, 56, 673- 682, 1989). PIM-1, 2, 3 are overexpressed in many hematological tumors (PNAS USA, 86, 8857-8861, 1989). PIM-1 has been found to be more expressed during the development of prostate cancer (J. Clin. Pathol., 59, 285-288, 2006), and PIM-2 is found in human chronic lymphocytic leukemia and non-Hodgkin's lymphoma. Expression is increased (Leuk. Lymph., 45, 951-955, 2004), while abnormal expression of PIM-3 is considered for hepatic fibroma (Int. J. Cancer, 114, 209-218, 2005) and pancreatic cancer (Cancer Res) The development and diffusion of 66, 6741-6747, 2006) played an important role.

PIM-1, 2, 3 usually respond to stimulation by growth factors and cytokines, thus contributing to the survival and spread of hematopoietic cells. Mice that excluded the PIM-1, 2, and 3 genes survived normally, but were smaller, and the response to growth factors was also attenuated during hematopoietic cell proliferation. If only one of the three PIMs was removed, there was no significant effect on the mice, and the functions of the three PIMs were overlapped (Cell, 56, 673-682, 1989). Substrates of action of PIM kinase include Bcl-2 family members that regulate apoptosis (FEBS Letters, 571, 43-49, 2004), p21 that regulates cell cycle (Biochim. Biophys. Acta, 1593, 45-55, 2002) ), CDC25A, C-TA, (J. Biol. Chem., 279, 48319-48328, 2004), and 4EBP1 (Blood, 105, 4477-4483, 2005) regulating protein synthesis. These effects of PIM kinase have been shown to have functions that prevent apoptosis and promote cell growth and spread. Therefore, overexpression of PIM kinase in tumors contributes to the survival and spread of cancer cells. Therefore, inhibition of overexpression of PIM kinase in tumors is a new and effective method for treating cancer.

Since PIM kinase is involved in many liquid and solid tumors, many PIM kinase inhibitors have been used to develop a new generation of anti-tumor drugs. In a series of cell and animal model experiments, PIM kinase inhibitors can significantly inhibit the proliferation of tumor cells including acute lymphoblastic leukemia (ALL), acute myeloid leukemia (AML), and chronic tumor growth. Granulocyte leukemia (CML), non-Hodgkin's lymphoma (NHL), and multiple myeloma (MM) (Clin. Cancer Res. 20 (7), 1834–1845, 2014; Blood 123 (6), 905– 913, 2014; Blood 122 (21), 4435, 2013). The results also show that PIM kinase inhibitors also have a good effect on solid tumors overexpressing PIM kinase, including pancreatic cancer (Cancer Biol. Ther. 7 (9), 1352-9, 2008 Cancer Res. 2006; 66 (13 ): 6741-7; Cancer Res. 70 (24), 10288–10298, 2010), Prostate Cancer (Prostate, 65(3), 276-86, 2005; Prostate, 73(13), 1462–1469, 2013) , Liver cancer (J. Surg. Res., 153 (1), 17-22, 2009; Int. J. Cancer, 114 (2), 209-18, 2005), gastric cancer (J. Cancer Res. Clin. Oncol. , 134 (4), 481-8, 2008) and bladder cancer (J. Exp. Clin. Cancer Res., 29, 161, 2010).

The emergence of anticancer drug resistance has been a major obstacle to chemotherapy and molecular targeted drugs (Drug Resistance Updat.12, 114–126.2009), and addressing the drug resistance of anticancer drugs is an important topic in cancer therapy. Many studies have shown that PIM kinase is involved in the expression and activity of two of the most important drug efflux transporters, MDR-1 and BCRP (Drug Resistance Updates, 14, 203–211, 2011). Experiments have shown that the combination of PIM kinase inhibitors and chemotherapy drugs can significantly improve the efficacy of drug-resistant prostate cancer (Mol. Cancer Ther. 8, 2882–2893, 2009). Therefore, PIM inhibitors can also be used to reverse resistance to chemotherapy.

Experiments have shown that PIM kinase expression is accompanied by activation of T-cells, and PIM-1/3 inhibitors are effective in treating enteritis caused by CD4+ T-cells. Oral clinical trial drug AR452530 can at least reduce rectal inflammation, glandular loss, edema and mucosa 80% hyperplasia (Cellular Immunology, 272, 200–213, 2012). Therefore, PIM inhibitors can also be used to treat T-cell mediated diseases such as inflammatory bowel disease.

According to the published literature on kinase inhibitors (US Pat. No. 5,952,455 B2):

Both formula A and formula B are PIM inhibitors. When their substituents R _a , R _b and R _c are the same, the only difference is the 5-position substituent on pyridine ring 1, general formula A is a hydrogen atom, and general formula B is a fluorine atom. The literature data shows that in all 29 pairs of compounds, whether the 5-position substituent is H or F has little effect on the PIM activity of these compounds and does not alter the ability of the compound to inhibit PIM-1 enzyme activity.

Summary of the invention

In the study of a new generation of PIM kinase inhibitors, we have unexpectedly found that, unlike known knowledge, in a group of compounds conforming to formula I, when other structures are identical, R ₆ is a cyclic structure. When R _{3 is} changed from H to other substituents, the steric hindrance increases, which hinders the free rotation of the R ₆ ring, thereby increasing their activity. When R _{3 is} replaced by F or CF ₃ , the highest activity is increased by 8 times or more, averaging 4.4 times, by increasing the lipophilicity of the molecule, thereby further enhancing the ability of the compound to inhibit PIM-1 activity. See Table 2 of Example 60 for specific data.

Detection and results of the biological activity of the compounds of the invention.

The biological activities of the compounds of the present invention were entrusted to Baonuo Technology (Beijing) Co., Ltd. (E, No. 29, Life Science Park Road, Changping District, Beijing) for testing. The test method is the in vitro activity assay of kinase PIM - IMAP fluorescence polarization method In vitro activity assay of kinase PIM - IMAP fluorescence polarization method

Principle

PIM is a serine/threonine protein kinase that phosphorylates 5-FAM-labeled small peptide substrates. The unphosphorylated substrate could not bind to the binding reagent (immobilized metal chelate beads) and the fluorescence polarization value was low. The phosphorylated small peptide can be bound to the binding reagent such that the fluorescence polarization value is increased. The degree of phosphorylation of 5-FAM-labeled small peptide substrates reflects the magnitude of PIM kinase activity. The ability of these compounds to inhibit PIM kinase activity can be determined by testing the inhibitory effect of the compounds of the invention on PIM kinase activity at a concentration.
