摘要
The AAA+ ATPase p97 (valosin-containing protein, VCP)is a masterregulator of protein homeostasis and therefore represents a noveltarget for cancer therapy. Starting from a known allosteric inhibitor,NMS-873, we systematically optimized this scaffold, in particular,by applying a benzene-to-acetylene isosteric replacement strategy,specific incorporation of F, and eutomer/distomer identification,which led to compounds that exhibited nanomolar biochemical and cell-basedpotency. In cellular pharmacodynamic assays, robust effects on biomarkersof p97 inhibition and apoptosis, including increased levels of ubiquitinatedproteins, CHOP and cleaved caspase 3, were observed. Compound (R)-29 (UPCDC-30766) represents the most potentallosteric inhibitor of p97 reported to date.
