Description

CB-6644 is a novel allosteric selective inhibitor of the ruvbl1/2 complex with anti-cancer activity. CB-6644 blocks the ATPase activity of RUVBL1/2 with an IC50 of 15 nM. CB-6644 interacts specifically with RUVBL1/2 in cancer cells, leading to cell death. Importantly, drug-acquired-resistant cell clones have amino acid mutations in either RUVBL1 or RUVBL2, suggesting that cell killing is an on-target consequence of RUVBL1/2 engagement. In xenograft models of acute myeloid leukemia and multiple myeloma, CB-6644 significantly reduced tumor growth without obvious toxicity.

How to use

In Vitro:

CB-6644 (20 µM) interacts with the RUVBL1/2 complex in Ramos cells. CB-6644 (0.001-10 μM; 72 hours) potently kills 123 cell lines (including HCT116, NCI-1975, and HT29 cells) with an EC50 range of 41 to 785 nM.

In Vivo:

CB-6644 (150 mg/kg, oral administration, 10 days of treatment for SCID-beige mice bearing Ramos xenograft models, 30 days of treatment for SCID-beige mice bearing RPMI8226 xenograft models) has antitumor activity in xenograft tumor models with tumor growth inhibitions (TGIs) of 68 and 81%, respectively in Ramos xenograft models and RPMI8226 xenograft models.
