What is ARS-1620?
The Uses of ARS-1620
ARS-1620, is an atropisomeric selective KRASG12C inhibitor with desirable pharmacokinetics.
Definition
ChEBI: ARS-1620 is a qinazoline derivative carrying chloro and fluoro substituents at positions 6 and 8 respectively, a 2-fluoro-6-hydroxyphenyl group at position 7, and a 4-(prop-2-enoyl)piperazin-1-yl group at position 4. A potent, selective, and orally bioavailable covalent KRAS-G12C inhibitor, it inhibits the protein coding gene KRAS (Kirsten rat sarcoma virus) with high potency in cells and animals. It has a role as an inhibitor, an antiviral agent and an antineoplastic agent.
