Biological target:
ML241 hydrochloride is a potent p97 inhibitor, inhibiting p97 ATPase with IC50 value of 100 nM.
In vitro activity:
Consistent with the role of p97 in the ubiquitin–proteasome system (UPS), ML240 and ML241, like the parent compound DBeQ, caused accumulation of ubiquitin conjugates in the nuclear plus membrane and cytosolic compartments at concentrations of 5–10 μm (Figure 4a). Interestingly, ML241 caused stronger accumulation than ML240, even though ML240 was more potent at stabilizing UbG76V–GFP. This, along with the cell proliferation data, points to unexpected complexity in the mechanism of action of these compounds.
