Description

Technical Field

[0001] This disclosure pertains to the pharmaceutical field and relates to a fused bicyclic compound, its preparation method, and its pharmaceutical application. In particular, this disclosure relates to fused bicyclic compounds of general formula (I), their preparation methods, pharmaceutical compositions containing such compounds, and their use in the preparation of medicaments for inhibiting HPK1. Background Technology

[0002] Cancer treatment has evolved from radiotherapy and chemotherapy to targeted therapy and now includes immunotherapy. The main targets of tumor immunotherapy include immune checkpoints, immune agonists, Tregs, macrophages, and tumor microenvironment metabolites such as IDO and the A2AR pathway. Hematopoietic progenitor kinase 1 (HPK1, also known as mitogen-activated protein kinase kinase 1 or MAP4K1) is a negative regulator within T cells, playing a negative feedback regulatory role after TCR activation and is associated with T cell exhaustion. A well-understood signaling pathway is as follows: after TCR binds to MHC-peptide, LAT is phosphorylated, recruiting the GADS-SLP76 complex, leading to phosphorylation and pathway activation of downstream PLCs. Simultaneously, ZAP70 phosphorylates the Y381 site of HPK1, which binds to the SH2 region of SLP76, thereby phosphorylating the latter's S376 site. SLP76 S376 phosphorylation recruits 14-3-3, leading to ubiquitination and causing the disintegration of the entire TCR signalosome.

[0003] HPK1 is considered a good target for immunotherapy for the following three reasons: (1) HPK1 expression is limited to immune cells and has good safety profile; (2) HPK1 has multiple negative regulatory effects at different stages of the cancer-immune cycle. Inhibiting HPK1 can regulate the immunosuppressive functions of NK cells, DC cells, and T cells, and can also regulate B cell activation, among which T cell activation has been studied the most; (3) HPK1 kinase activity is important in inhibiting anti-cancer immune responses.

[0004] Studies have shown that HPK1 expression is associated with T cell exhaustion signatures, including CD3E, PD1, CTLA4, TIM-3, LAG-3, and TIGIT, and high HPK1 expression is associated with shorter survival. Analysis of the TCGA PanCancer database showed a positive correlation between HPK1 expression (but not other MAP4K family members) and PD1. HPK1 expression is upregulated in exhausted T cells, and HPK1, TIM3, and LAG3 expression is higher in T cells with high PD1 than in T cells with low PD1. Conversely, HPK1 expression is downregulated in CD4+ T cells of patients with systemic lupus erythematosus (SLE), and the SLEDAI score is negatively correlated with HPK1 mRNA levels. HPK1 expression is also downregulated in peripheral blood cells of patients with psoriatic arthritis (PsA).

[0005] HPK1 knockout mice show no abnormalities at rest. However, once the TCR is activated, the results are similar regardless of whether the mice are HPK1 knockout, HPK1 kinase-dead knock-in, or SLP76S376A knock-in, all of which activate an immune response. HPK1-deficient mice are more susceptible to experimental autoimmune encephalomyelitis (EAE). HPK1 kinase activity regulates TCR signaling and cytokine secretion in vitro; inhibiting HPK1 can alleviate PGE2 and adenosine-mediated immunosuppression. HPK1 kinase-dead mice inhibit tumor growth in vivo, and the anti-tumor effect of HPK1- / - mice almost disappears after the removal of CD8+ or CD4+ T cells, indicating that T cells mediate most of the immunosuppressive effects of HPK1.

[0006] The data from HPK1 knockout and kinase dead knock-in mice indicate that HPK1 mainly functions through kinase activity. However, some literature reports that its scaffold also has a certain function. Therefore, the development strategy for drugs that inhibit HPK1 is mainly based on kinase inhibitors, and there are also some PROTAC molecules.
