Description

Technical Field

[0001] The present invention relates to an isobenzofuran-1(3H)-one derivative and uses thereof, and more specifically, to an isobenzofuran-1(3H)-one derivative having HPK1 inhibitory activity and MLK3 inhibitory activity and a pharmaceutical composition containing the same for preventing or treating cancer, viral infection diseases, Parkinson's disease, non-alcoholic fatty hepatitis or tuberculosis. Background Art

[0002] Protein kinase is a catalytic enzyme that catalyzes the transfer of the terminal phosphate group of adenosine triphosphate (ATP) to specific residues (tyrosine, serine and threonine) of proteins and participates in the signaling that regulates cell activity, growth and differentiation 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 phosphorylated (Hanks, SK et al., FASEB J., 9(8), 576-596, 1995). The serine / threonine kinase group includes protein kinase C isoforms (Newton, AC, J Biol Chem., 270(48), 28495-28498, 1995), cyclin-dependent kinase group and cdc2 (Pines, J., Trends Biochem Sci., 18(6), 197, 1993). The tyrosine kinase component is divided into: transmembrane 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, AC et al., Annu Rev Immunol., 12, 555-592, 1994).

[0004] Inappropriately high protein kinase activity is directly or indirectly associated with a variety of diseases that result from abnormal cellular action. For example, disease may arise due to failure of appropriate regulatory mechanisms of kinases associated with mutation, overexpression or inappropriate enzyme activity, or overproduction or underproduction of factors involved in signal transduction upstream or downstream of cytokines or kinases. Thus, selective inhibition of kinase activity may be a favorable target for the development of new drugs for the treatment of disease.

[0005] MLK3 is a member of the mixed lineage kinase (MLK) family and can regulate MAP kinases (especially JNK) that play an important role in the proliferation and survival of cancer cells by using a variety of signal transduction systems.

[0006] In addition, many studies are currently underway to develop compounds that inhibit MLK3 enzyme activity as therapeutic agents for cancer, viral infections, Parkinson's disease, non-alcoholic steatohepatitis, etc. (Chadee, DN, 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 Set al., J Med Chem., 56(20), 8032-8048, 2013; Jiang, JX et al., Livermore Int.,34(8),1131-1132,2014;Tomita,K.et al.,JCI Insight.,2(15),94488,2017;Ibrahim,SHetal.,LiverInt.,34(3),427-437,2014;Parkinson Study Group PRECEPT Investigators, Neurology, 69(15), 1480-1490, 2007; Kline, EM et al., Exp Neurol., 318, 157-164, 2019).

[0007] Hematopoietic progenitor kinase 1 (HPK1) cloned from primitive hematopoietic progenitor cells is a series of many MAP kinase kinase kinase kinases (MAP4Ks), including: MAP4K1 / HPK1, MAP4K2 / GCK, MAP4K3 / GLK, MAP4K4 / HGK, MAP4K5 / KHS and MAP4K6 / MINK (Hu, MC, et al., Genes Dev, 1996. 10 (18): p. 2251-64). Interestingly, HPK1 is mainly expressed in hematopoietic cells such as T cells, B cells, macrophages, dendritic cells, neutrophils and mast cells (Hu, MC, et al., Genes Dev, 1996. 10 (18): p. 2251-64; Kiefer, F., et al., EMBO J, 1996. 15 (24): p. 7013-25). It is proposed that HPK1 kinase activity is induced upon activation of 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 receptor (EP2 and EP4) (Ikegami, R., et al., J Immunol, 2001. 166(7): p.4689-96). As mentioned above, HPK1 regulates multiple functions of various immune cells.

[0008] HPK1 is very important in regulating the functions of various immune cells and is associated with autoimmune diseases and anti-tumor immunity (Shui, JW, 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, JW, et al., Nat Immunol, 2007.8(1): p.84-91). In humans, HPK1 is downregulated in peripheral blood mononuclear cells of patients with psoriatic arthritis and T cells of patients with systemic lupus erythematosus (SLE) (Batliwalla, FM, et al., Mol Med, 2005.11(1-12): p.21-9). These observations suggest that the reduction in HPK1 activity may be caused by the patient's autoimmunity. In addition, HPK1 can also control anti-tumor immunity through T cell-dependent mechanisms. In a PGE2-producing lung cancer tumor model, tumors developed more slowly in HPK1 knockout mice compared to wild-type mice (see US2007 / 0087988). In addition, adoptive transfer of HPK1-deficient T cells has been proposed to be 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 are more effective in increasing T cell responses to eradicate Lewis lung cancer compared to wild-type BMDCs (Alzabin, S., et al., J Immunol, 2009.182(10): p.6187-94). In addition, it has been reported that cancer patients with high HPK1 expression have a lower survival rate than cancer patients with low expression. However, according to recent reports, inhibiting HPK1 expression in cancer cells themselves can inhibit cancer growth. In addition, in various CAR-T cells such as CD19CAR-T, Her2 CAR-T, B cell maturation antigen (BCMA) CAR-T (chimeric antigen receptor T cell), etc., which are anti-cancer immune cells, if HPK1 expression is inhibited, the anti-cancer immune ability of CAR-T is increased, thereby effectively inhibiting the proliferation and growth of cancer cells (Si, J., et al., Cancer Cell, 2020, 38(4): p.551-66).These data, together with the restricted expression of HPK1 in hematopoietic cells and the lack of effect on the normal development of immune cells, suggest that HPK1 may be an excellent drug target for enhancing anti-tumor immunity. In addition, the most important immunotherapy using T cells is ex vivo culture, which is a technology for rapidly proliferating a large number of high-quality T cells in a culture container (Dudley, ME., et al., Nat. Rev. Cancer, 2003, 3(9): p.666-75). If combined with a technology that can regulate the differentiation and proliferation of hematopoietic cells in a culture container, new T cell culture technology for immunotherapy can be developed. Therefore, new compounds that regulate HPK1 activity are needed.

[0009] On the other hand, as an existing document related to isobenzofuran-1(3H)-one derivatives having HPK1 inhibitory activity and MLK3 inhibitory activity and pharmaceutical compositions containing the same for preventing or treating cancer, viral infection diseases, Parkinson's disease, non-alcoholic fatty hepatitis or tuberculosis, Korean Patent No. 10-0832602 discloses a novel polycyclic compound related to the activity of MLK3 enzyme and its use. However, there is no mention or report of isobenzofuran-1(3H)-one derivatives of Chemical Formula 1 and Chemical Formula 2 of the present invention and the HPK1 and MLK3 inhibitory activities of the derivatives, and the ability to treat cancer, viral infection diseases, Parkinson's disease, non-alcoholic fatty hepatitis or tuberculosis thereby.
