Application

MS-873 has been used as an allosteric inhibitor of ATPase valosin-containing protein (VCP)/p97.

Biochem/physiol Actions

NMS-873 is a selective allosteric non–ATP-competitive inhibitor of the AAA ATPase family member valosine containing protein (VCP), also known as p97 (VCP/p97), an integral component of the ubiquitin fusion degradation (UFD) pathway. VCP/p97 plays a role in degradation of misfolded proteins, Golgi membrane reassembly, membrane transport, myofibril assembly, autophagosome maturation, and cell division, and is overexpressed in many tumor types. NMS-873 is the most potent and specific VCP inhibitor described to date. NMS-873 has an IC50 of 30 nM for VCP/p97 compared to IC50 >10 μM against all of the AAA ATPases, HSP90 or the 53 kinases analyzed. NMS-873 inhibited proliferation of HCT116 cancer cell line cells with an IC50 value of 400 nM.

The AAA+ ATPase p97/VCP together with different sets of substrate-delivery adapters and accessory cofactor proteins unfolds ubiquitinated substrates to facilitate degradation by the proteasome. The UBXD1 cofactor is connected to p97-associated multisystem proteinopathy but its biochemical function and structural organization

The transcription factor NRF1 resides in the endoplasmic reticulum (ER) and is constantly transported to the cytosol for proteasomal degradation. However, when the proteasome is defective, NRF1 escapes degradation and undergoes proteolytic cleavage by the protease DDI2, generating a transcriptionally
