Biological Activity for NMS 873

NMS 873 is a potent p97 ATPase (VCP) allosteric inhibitor (IC50 = 30 nM). Selective over all other AAA ATPases, HSP90 and kinases tested (IC50 >10 μM). Activates the unfolded protein response (UPR) and modulates autophagosome maturation. Exhibits antiproliferative activity in cancer cells in vitro (IC50 values are 400 and 700 nM for HCT116 and HeLa cells respectively). Reduces p97-sensitization to trypsin digestion.

NMS on Dictyostelium mTORC1.
By Judith Schaf on 05/23/2019
Assay Type: In Vitro
Species: Other

Used NMS at 30 nM and 300 nM in Dictyostelium, treated for 1 hour or 24 hours. Then mTORC1 activity was monitored using a western blot for p-4E-BP1. No significant change in p-4E-BP1 levels was observed
