Pevonedistat, also known as MLN-4924 and TAK-924, is a small molecule inhibitor of Nedd8 activating enzyme (NAE) with potential antineoplastic activity. NAE inhibitor MLN4924 binds to and inhibits NAE, which may result in the inhibition of tumor cell proliferation and survival. NAE activates Nedd8 (Neural precursor cell expressed, developmentally down-regulated 8), an ubiquitin-like (UBL) protein that modifies cellular targets in a pathway that is parallel to but distinct from the ubiquitin-proteasome pathway (UPP).
Pevonedistat hydrochloride (MLN4924 hydrochloride) is a potent and selective NEDD8-activating enzyme (NAE) inhibitor, with an IC50 of 4.7 nM.
