Description:

NMS-859 is a potent and specific small molecule covalent inhibitor of the ATPase VCP/p97 (IC50 ~0.37 µM), identified by high-throughput screening. It is very selective (IC50 >10 μM) against all of the AAA ATPases, HSP90 or the 53 kinases tested. NMS-859 was active in a cell proliferation assay, with IC50 values of 3.5 μM and 3.0 μM in HCT116 and HeLa cell lines, respectively. NMS-859 covalently modifies VCP on the active site Cys522 and blocks ATP binding. NMS-859 provided critical validation of VCP as a cancer target, and it raises the possibility that targeting VCP might prevent proteasome inhibitor–resistant tumors from escaping through the aggresome-autophagy pathways and cause them to collapse under the high load of unfolded proteins.
