Description

Technical Field

[0001] The present invention relates to isobenzofuran-1(3H)-one derivatives and their uses, and more specifically, to isobenzofuran-1(3H)-one derivatives having HPK1 inhibitory activity and MLK3 inhibitory activity, and pharmaceutical compositions for preventing or treating cancer, viral infectious diseases, Parkinson's disease, non-alcoholic steatohepatitis or tuberculosis containing the same.

Background Art

[0002] Protein kinases are enzymes that catalyze the reaction of transferring the terminal phosphate group of adenosine triphosphate (ATP) to specific residues (tyrosine, serine, threonine) of proteins, and are involved in signals that regulate the activity, growth, and differentiation of cells in response to extracellular mediators and environmental changes.

[0003] Generally, protein kinases are classified into serine and / or threonine kinase groups and tyrosine kinase groups according to the substrates they phosphorylate (Hanks, S.K. et al., FASEB J., 9(8), 576-596, 1995). The serine / threonine kinase group includes protein kinase C isoforms (Newton, A.C., J Biol Chem., 270(48), 28495-28498, 1995), cyclin-dependent kinase groups, and cdc2 (Pines, J., Trends Biochem Sci., 18(6), 197, 1993). The tyrosine kinase group is divided into membrane-spanning growth factor receptors including epidermal growth factor receptor (Iwashita, S. et al., Cell Signal., 4(2), 123-132, 1992), cytoplasmic non-receptor kinases including p56tck, p59fYn, ZAP-70, and C-terminal Src kinase (Chan, A.C. et al., Annu Rev Immunol., 12, 555-592, 1994).

[0004] Undesirably high protein kinase activity is directly or indirectly associated with a number of diseases resulting from abnormal cellular function. For example, diseases can occur due to failure of the appropriate regulatory mechanisms of kinases associated with mutation, overexpression, or inappropriate enzyme activity; or due to over- or under-production of factors participating in upstream or downstream signaling of cytokines or kinases. Therefore, selective inhibition of kinase activity can be a beneficial target for the development of new drugs for the treatment of diseases.

[0005] MLK3 is one of the MLK (mixed lineage kinase) family and can regulate MAP kinases (especially JNK), which are important for cancer cell proliferation and survival, using various signaling systems.

[0006] In addition, in recent years, numerous studies have been conducted to develop therapeutic agents for cancer, viral infectious diseases, Parkinson's disease, non-alcoholic steatohepatitis, etc. by developing compounds that inhibit the enzymatic activity of MLK3 (Chadee, D.N., Can J Physiol Pharmacol., 91(4), 268-274, 2013; Rattanasinchai, C. et al., Cancers (Basel)., 8(5), 51, 2016; Xu, H. et al., J Virol., 93(18), e00758-19, 2019; Saminathan, P. et al., J Neuroimmune Pharmacol., 14(1), 44-51, 2019; Goodfellow, V.S. et al., J Med Chem., 56(20), 8032-8048, 2013; Jiang, J.X. et al., Liver Int., 34(8), 1131-1132, 2014; Tomita, K. et al., JCI Insight., 2(15), 94488, 2017; Ibrahim, S.H. et al., Liver Int., 34(3), 427-437, 2014; Parkinson Study Group PRECEPT Investigators, Neurology, 69(15), 1480-1490, 2007; Kline, E.M. et al., Exp Neurol., 318, 157-164, 2019).

[0007] Hematopoietic progenitor kinase 1 (HPK1), originally cloned from hematopoietic progenitor cells, belongs to a large family of mitogen-activated protein kinase kinase kinase kinases (MAP4Ks), which includes MAP4K1 / HPK1, MAP4K2 / GCK, MAP4K3 / GLK, MAP4K4 / HGK, MAP4K5 / KHS, and MAP4K6 / MINK (Hu, M.C., et al., Genes Dev, 1996. 10(18): p. 2251-64). HPK1 is of particular interest because it is predominantly expressed in hematopoietic cells such as T cells, B cells, macrophages, dendritic cells, neutrophils, and mast cells (Hu, M.C., et al., Genes Dev, 1996. 10(18): p. 2251-64; Kiefer, F., et al., EMBO J, 1996. 15(24): p. 7013-25). HPK1 kinase activity has been shown to be induced upon activation of the T cell receptor (TCR) (Liou, J., et al., Immunity, 2000. 12(4): p. 399-408), B cell receptor (BCR) (Liou, J., et al., Immunity, 2000. 12(4): p. 399-408), transforming growth factor receptor (TGF-βR) (Wang, W., et al., J Biol Chem, 1997. 272(36): p. 22771-5; Zhou, G., et al., J Biol Chem, 1999. 274(19): p. 13133-8), or Gs-coupled PGE2 receptors (EP2 and EP4) (Ikegami, R., et al., J Immunol, 2001. 166(7): p. 4689-96). Thus, HPK1 regulates diverse functions of various immune cells.

[0008] HPK1 is important in regulating the functions of various immune cells and is involved in autoimmune diseases and antitumor immunity (Shui, J.W., et al., Nat Immunol, 2007.8(1): p. 84-91; Wang, X., et al., J Biol Chem, 2012.287(14): p. 11037-48). HPK1 knockout mice are more sensitive to the induction of experimental autoimmune encephalomyelitis (EAE) (Shui, J.W., et al., Nat Immunol, 2007.8(1): p. 84-91). In humans, HPK1 was downregulated in peripheral blood mononuclear cells of psoriatic arthritis patients and in T cells of systemic lupus erythematosus (SLE) patients (Batliwalla, F.M., et al., Mol Med, 2005.11(1-12): p. 21-9). According to these observations, attenuation of HPK1 activity may be attributed to the patients' autoimmunity. Also, HPK1 can control antitumor immunity through a T cell-dependent mechanism. In a PGE2-producing lung cancer tumor model, tumors developed relatively slower in HPK1 knockout mice compared to wild-type mice (see US2007 / 0087988). Also, it was shown that adoptive transfer of HPK1-deficient T cells was more effective in controlling tumor growth and metastasis compared to wild-type T cells (Alzabin, S., et al., Cancer Immunol Immunother, 2010.59(3): p. 419-29). Similarly, BMDCs from HPK1 knockout mice were more effective than wild-type BMDCs in increasing the T cell response to eradicate Lewis lung carcinoma (Alzabin, S., et al., J Immunol, 2009.182(10): p. 6187-94).In addition, although it has been reported that cancer patients with high expression of HPK1 have a lower survival rate compared to cancer patients showing low expression, if the expression of HPK1 in cancer cells themselves is suppressed, cancer growth is suppressed, and in various CAR-T cells such as CD19CAR-T, Her2CAR-T, and BCMA (B cell maturation antigen) CAR-T (Chimeric Antigen Receptor-modified T cell), which are anti-cancer immune cells, suppressing HPK1 expression recently reported that the anti-cancer immune ability of CAR-T increases and effectively inhibits cancer cell proliferation and growth (Si, J., et al., Cancer Cell, 2020, 38(4): p. 551-66). These data suggest that, along with the restricted expression of HPK1 in hematopoietic cells and the lack of effect on the normal development of immune cells, HPK1 is an excellent drug target for enhancing anti-tumor immunity. In immunotherapy using T cells, the most important is ex vivo culture, which is a technique for rapidly growing a large number of high-quality T cells on a culture vessel (Dudley, ME., et al., Nat. Rev. Cancer, 2003, 3(9): p. 666-75). When a technique capable of regulating the differentiation and proliferation of hematopoietic cells in a culture vessel is used in combination, a new T cell culture technique for immunotherapy can be developed. Therefore, there is a need for a new compound that regulates HPK1 activity.

[0009] On the other hand, as a prior art document related to isobenzofuran-1(3H)-one derivatives having HPK1 inhibitory activity and MLK3 inhibitory activity and a pharmaceutical composition containing the same for preventing or treating cancer, viral infectious diseases, Parkinson's disease, non-alcoholic steatohepatitis, or tuberculosis, Korean Registered Patent No. 10-0832602 has disclosed a novel polycyclic compound related to the activity of the MLK3 enzyme and its uses. However, there has been no report yet mentioning the isobenzofuran-1(3H)-one derivatives such as Chemical Formulas 1 and 2 of the present invention, the HPK1 and MLK3 inhibitory activities of the derivatives, and the fact that cancer, viral infectious diseases, Parkinson's disease, non-alcoholic steatohepatitis, or tuberculosis can be treated thereby.

[0010] Therefore, in the process of researching isobenzofuran-1(3H)-one derivatives, the present inventors confirmed all of the HPK1 inhibitory activity and the inhibitory activity against MLK3, and thus completed the present invention.

[0170] That HPK1 can be inhibited to increase the activity of T cells was observed from the following experiments. Human PBMC cells were seeded at 2×10 per well in a 96-well plate. 5They were diluted serially from 3 μM of the compounds 1 to 3 of the present invention synthesized in Example 1 and pretreated for 1 hour. Then, CD3 / CD28 dynabeads were treated at a ratio of 1:1 with the cell number and cultured for 6 days. After culturing, the cells and the medium were measured with an iQue device using a human T cell activation cell and cytokine profiling kit manufactured by Zaltron. IL-2, which is utilized as a biomarker for increased T cell activity, was measured, and the result value was calculated with the positive control group treated with dynabeads only set as 100%.

[0171] Looking at FIG. 2 showing the results, since Compound 1 or 2 increases IL-2, it can be seen that the compound has an activity of increasing T cell activity.

[0172] In addition, the characteristic HPK1 and MLK3 inhibitory activities of the isobenzofuran-1(3H)-one derivatives of the present invention were confirmed to be produced as immune activity-amplifying cells by co-administration during ex vivo culture of therapeutic cells used in combination with conventional anticancer drugs or immunomodulatory cell therapy agents, or that immune cells can be amplified and produced. From this, a synergistic anticancer effect was confirmed.
