Daraxonrasib
Based on 17 publication(s) in Google Scholar
Daraxonrasib (RMC-6236) is an orally active, non-covalent RAS (ON) inhibitor. Daraxonrasib disrupts the interaction of wild-type or mutant RAS proteins with the RAS binding domain of BRAF, with EC50 values ranging from 28-220 nM for wild-type KRAS, NRAS, HRAS, and multiple oncogenic RAS variants. Daraxonrasib inhibits pERK. Daraxonrasib has anti-tumor activity against KRAS mutant tumors.

Daraxonrasib (EC50 of 1.2 nM for HPAC cells and 1.4 nM for Capan-2 cells; 120 h) potently inhibits the growth of KRAS mutant cancer cell lines HPAC and Capan-2[1].
Daraxonrasib (10 nM; 0-48 h) cannot durably inhibit mTOR activity when used alone in GP2D colorectal cancer cells, but it can control the rebound of mTOR activity when combined with KO-2806[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Daraxonrasib (10-25 mg/kg; p.o.; once daily; 4 weeks) shows dose-dependent antitumor activity in a series of human tumor xenograft models harboring prevalent KRAS mutations (such as Capan-2, NCI-H441, HPAC, NCI-H358, etc.)[1].
Daraxonrasib (25 mg/kg; p.o.; once daily) can arrest tumor growth when used alone in xenograft models of KRASG12C-mutant NCI-H2122 non-small cell lung cancer and KRASG12D-mutant GP2D colorectal cancer, and it can lead to significant tumor regression when combined with KO-2806[2].
