Definitions
- the invention belongs to the technical field of medicine science, and particularly relates to HPK1 inhibitors and preparation method thereof.
- Hematopoietic progenitor kinase 1 is involved in many signaling cascades, including growth factor signaling, MAPK signaling, cytokine signaling, apoptotic signaling, and antigen receptor signaling.
- HPK1 is a key functional activating factor of the JNK/SAPK signaling pathway. When activated, it selectively activates the MAPK signaling pathway of C-Jun N-terminal kinase (JNK) .
- HPK1 as a possible target for immunotherapy, which is activated by lymphocyte antigen receptors and inhibits AP-1, while AP-1 promotes cell proliferation, inhibits differentiation, and promotes tumor cell invasion during tumor formation and progression.
- Targeted disruption of HPK1 alleles confers T cells with an elevated Th1 cytokine production in response to TCR engagement.
- HPK1 as a novel target for cancer immunotherapy, Immunol Res, 54 (2012) , pp. 262–265) reported that HPK1 (-/-) T cells proliferate more rapidly than the haplotype-matched wild-type counterpart and are resistant to prostaglandin E2 (PGE 2) -mediated suppression.
- PGE 2 prostaglandin E2
- the loss of HPK1 from dendritic cells (DCs) endows them with superior antigen presentation ability, enabling HPK1 (-/-) DCs to elicit a more potent anti-tumor immune response when used as cancer vaccine.
- HPK1 kinase activity may activate the superior anti-tumor activity of both cell types, resulting in a synergistic amplification of anti-tumor potential.
- HPK1 is not expressed in any major organs, it is less likely that an inhibitor of HPK1 kinase activity would cause any serious side effects.
- compositions and methods for enhancing an immune response and treating cancer are provided.
- Compositions comprise PD-1 axis antagonists and HPK1 antagonists.
- HPK1 antagonists include compounds that inhibit the serine/threonine kinase activity of HPK1.
- HPK1 plays a key role in the treatment of diseases, especially cancer, and the discovery of HPK1 small molecule inhibitors has become an important direction for anti-tumor drug research.
- Figure 1 presents bar graphs showing that representative compounds of the present disclosure are effective in enhancing cytotoxicity of the tested Car-T cells.
