UTE-156 is a potent, covalent small-molecule inhibitor of VCP/p97 AAA+ ATPase with IC50 of 10 nM, modifies Cys522 within the D2 ATPase domain of VCP.
The C522A mutant displayed markedly reduced sensitivity (IC50 >10 uM).
UTE-156 does not inhibit structurally related AAA+ ATPase Spastin, which does not contain cysteine in its Walker A motif.
UTE-156 reduced viability with an IC50 of 1.6 uM in A549 lung carcinoma cells, but not HCT116 colorectal carcinoma cells (IC50>100 uM).
