描述 | CPI-455 Hydrochloride is the hydrochloride form of CPI-455. CPI-455 is a specific KDM5 inhibitor with IC50 value of 10nM for inhibition of full-length KDM5A in enzymatic assays. CPI-455-mediated KDM5 inhibition resulted in a dose-dependent increase in global H3K4me3 in HeLa cells. Also it induced a time-dependent increase in H3K4me3 that was detected only after 2 or more days of treatment. The elevation of H3K4 trimethylation mediated by this inhibition of KDM5 by CPI-455 decreased the number of drug-tolerant state in multiple cancer cell line models treated with standard chemotherapy or targeted agents[2]. | ||
作用机制 | The nitrile of CPI-455 makes a single interaction with the active-site metal ion of KDM5. The position occupied by CPI-455 completely overlaps the binding site of 2-OG, demonstrating a competitive mode of action.[1] |
