KRAS G12D inhibitor 14 is a potent KRAS G12D inhibitor with a K D of 33 nM for binding to KRAS G12D protein. KRAS G12D inhibitor 14 decreases the active form of KRAS G12D (KRAS G12D-GTP) but not KRAS G13D In Vitro KRAS G12D inhibitor 14 (compound KD-8) shows antiproliferative activity with an IC50 of 2.1 μM against three KRAS G12D-mutated cells (Panc1, SW1990 and CT26). KRAS G12D inhibitor 14 decreases the active form of KRAS (KRAS-GTP) in KRAS G12D mutated cancer cell lines (CT26 and SW1990) but not in KRAS G13D mutated cancer cell lines (HCT116). KD-8 also causes efficient apoptosis of SW1990 and CT26 cancer cells. KRAS G12D inhibitor 14 down-regulates the phosphorylated Raf and Erk in CT26 and SW1990 cancer cell lines but not in HeLa cells (KRAS WT). MCE has not independently confirmed the accuracy of these methods. They are for reference only. In Vivo KRAS G12D inhibitor 14 (compound KD-8) (40 mg/kg or 60 mg/kg; i.p.) exhibits significant antitumor efficacy in a CT26 tumor model with a tumor growth inhibition (TGI) of 42% or 53% without causing apparent toxicity . MCE has not independently confirmed the accuracy of these methods. They are for reference only. Form:Solid IC50& Target:KRas G12D 33 nM (Kd)
