AGPAT4-IN-1

AGPAT4-IN-1 (Compound CL26) is a covalent AGPAT4 inhibitor with an IC50 of 795 nM. AGPAT4-IN-1 covalently binds to AGPAT4 at Cys228 and significantly inhibits acyltransferase activity, LPA-to-PA conversion and downstream mTOR/S6K pathways. AGPAT4-IN-1 sensitizes hepatocellular carcinoma (HCC) tumors to Sorafenib (HY-10201) and significantly induces apoptosis with a synergistic response. AGPAT4-IN-1 has antitumor activity and reduces tumorigenicity and stemness in HCC xenograft mouse models.
