Adagrasib (MRTX849) is an orally active and selective covalent inhibitor of KRAS G12C. Adagrasib binds to the GDP state of the inactive conformation of KRAS G12C and inhibits KRAS and its downstream signaling. Adagrasib exhibits inhibitory activity against KRAS G12C mutant tumors.

PARP7-IN-24 (compound 44) is a potent inhibitor of PARP7, demonstrating an EC50 of 0.375 nM for pSTAT1 in NCI-H1373 cells. It shows potential for use in cancer research.

PARP7-IN-23 (compound 56) is a potent PARP7 inhibitor with an EC50 of 0.915 nM for pSTAT1 in NCI-H1373 cells, indicating its potential for cancer research.

Pan-RAS-IN-6 (compound 24) serves as a DUSP6 inhibitor, effectively reducing MAPK activation in the NCI-H1373-Luc model (DUSP6). It concurrently exhibits notable tumor growth inhibition and regression in the NSCLC brain metastasis mouse model. The compound displays high selectivity and potent inhibitory effects, particularly on KRAS mutation-associated signaling pathways. It demonstrates varied inhibitory activities against distinct KRAS mutants and their interacting proteins. The IC 50 values for KRAS G12C, G12D, and G12V are 1.3 nM, 4.7 nM, and 0.3 nM, respectively.
