CB-6644

CB-6644 is a selective inhibitor of the RUVBL1/2 complex and blocks the ATPase activity of RUVBL1/2 (IC50 = 15 nM) . (In Vitro) :CB-6644 (20 μM) interacts with the RUVBL1/2 complex in Ramos cells. In 123 cell lines such as HCT116, NCI-1975, and HT29 cells, CB-6644 (0.001-10 μM; 72 hours) potently kills 123 cell lines (EC50: 41 to 785 nM) . (In Vivo) :Administration of oral gavage once (qd) or twice (BID) daily, 10 days of treatment for Ramos, 30 days of treatment for RPMI8226, CB-6644 has antitumor activity in xenograft tumor models. The tumor growth inhibitions (TGIs) are 68 and 81%, respectively in Ramos xenograft models and RPMI8226 xenograft models.
