sotorasib

Sotorasib (AMG-510) is an orally active and selective covalent inhibitor of KRAS G12C. Sotorasib binds to the GDP state of the inactive conformation of KRAS G12C and inhibits KRAS and its downstream signaling. Sotorasib exhibits inhibitory activity against KRAS G12C mutant tumors.

(S)-AMG-510 is the S-type compound of AMG-510 (Sotorasib), which effectively and selectively inhibits KRASG12C through covalent interaction with mutant cysteine, thereby promoting clinical efficacy in KRASG12C tumors.

HRX-0233 is a small molecule inhibitor targeting MAP2K4. In vivo, HRX-0233 effectively reduces tumors in H358 KRASG12C mutant non-small cell lung cancer (NSCLC) without significant toxicity. This compound also prevents feedback activation of receptor tyrosine kinases (RTKs) when used as a monotherapy with the KRAS inhibitor Sotorasib, leading to more sustained and comprehensive inhibition of the MAPK signaling pathway. HRX-0233 holds potential for research in AR-negative prostate cancer, lung cancer, and colon cancer.
