产品描述:
NEDD8 is an ubiquitin-like protein whose activity is required to activate cullin-RING ubiquitin E3 ligases (CRLs) responsible for the ubiquitination and proteasome-dependent turnover of certain substrates with roles relevant to cellular processes important for cancer cell survival. Neddylation of CRLs is initiated by NEDD8-activating enzyme (NAE), which has become a novel target in cancer therapeutic research.{24455} MLN4924 is an analog of adenosine 5’-monophosphate that selectively inhibits NAE (IC50 = 4.7 nM).{24454} At much higher concentrations, MLN4924 inhibits the related enzymes ubiquitin-activating enzyme (UAE) and SUMO-activating enzyme (SAE) with IC50 values of 1.5 and 8.2 μM, respectively.{24454} At 0.3 μM, MLN4924 has been shown to disrupt CRL-mediated protein turnover leading to apoptosis in HCT116 cells by deregulating S-phase DNA synthesis.{24454} In vivo, 30-60 mg/kg MLN4924 dose-dependently suppresses the growth of human tumor xenografts in mice.{24454}
