    Product Description

    ARS1620 is a covalent inhibitor of K-RASG12C (IC50 = <3 μM).1 It selectively inhibits growth of H358, MIA-PaCa2, and LU65 cancer cells that express K-RASG12C (IC50s = 150 nM) over H441, A549, and HCT116 cells expressing wild-type K-RAS (IC50s = >10 μM). ARS1620 (200 mg/kg) induces tumor regression in a MIA-PaCa2, but not an H441, mouse xenograft model. It also decreases tumor volume in patient-derived xenograft (PDX) mouse models expressing K-RASG12C, but not K-RASG12D or wild-type K-RAS.

    WARNING This product is not for human or veterinary use.
