Description

The original application claimed priority as follows: CN202110089720X, filed on January 22, 2021. Technical Field

[0002] This invention relates to an HPK1 inhibitor, its preparation method, pharmaceutical composition, and its application. Background Technology

[0003] Hematopoietic progenitor cell kinase 1 (HPK1, also known as MAP4K1) is a member of the MAP4K family and is a serine / threonine kinase. It is mainly expressed in immune cells and plays a role in regulating immune cell function.

[0004] In T cells, activation of the T cell receptor (TCR) signaling pathway leads to the recruitment of cytoplasmic HPK1 to the cell membrane, where it binds to and phosphorylates the adaptor protein SLP76. This promotes the binding of SLP76 to E3 ligase 14-3-3, resulting in the degradation of the SLP76 / LAT signaling body, thereby negatively regulating the T cell receptor (TCR) pathway and inhibiting T cell activation and effector T cell function. Compared to wild-type, HPK1 knockout (HPK1 - / - T cells with inactivated HPK1 kinase (HPK1 KD) exhibited stronger proliferative capacity and higher cytokine expression levels. The mRNA and protein expression levels of HPK1 were also significantly reduced in CD4+ T cells from patients with systemic lupus erythematosus.

[0005] HPK1 can control anti-tumor immune mechanisms in a T-cell-dependent manner. - / - In tumor-bearing mice with HPK1 KD, T cells exhibited strong tumor cell killing ability, while tumor cells expressing the immunosuppressive molecule PGE2 showed strong tumor cell killing ability in HPK1-dependent tumor cells. - / - Compared to wild-type HPK1 KD mice, they grew more slowly. Analysis of the tumor microenvironment in HPK1 KD mice revealed significantly increased expression of key immune cell biomarkers involved in anti-tumor immunity, such as CD4, CD8, IFNγ, and Granzyme B. Expression of genes related to pro-inflammatory pathways, including the chemokine CXCL14, was also significantly increased, while expression of genes related to Th2 and Treg decreased.

[0006] In 25 types of human cancers, HPK1 expression was significantly positively correlated with the T-cell exhaustion marker PD-1, and also positively correlated with other T-cell exhaustion markers such as TIGIT, CTLA-4, and LAG3 in various tumors. Decreased HPK1 expression in low-grade glioma (LGG) and clear cell renal cell carcinoma (KIRC) was associated with prolonged patient survival, while HPK1 amplification in pancreatic cancer (PAAD) and metastatic breast cancer (BRAC) was associated with poor prognosis.

[0007] Furthermore, HPK1 is also a negative regulator of B cell and dendritic cell activation and plays an important role in maintaining Treg cell function. In summary, HPK1 has multifaceted anti-tumor immunopromoting effects and is a potential therapeutic target for tumor immunotherapy and autoimmune diseases. Summary of the Invention
