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.
