Description：Pevonedistat hydrochloride (MLN4924 hydrochloride) is a potent and selective NEDD8-activating enzyme (NAE) inhibitor, with an IC50 of 4.7 nM.

In Vitro：Pevonedistat (MLN4924) is a potent inhibitor of NAE (half-maximal inhibitory concentration (IC50=0.004 μM), and is selective relative to the closely related enzymes UAE, SAE, UBA6 and ATG7 (IC50=1.5, 8.2, 1.8 and >10 μM, respectively). Pevonedistat (MLN4924) treatment inhibits overall protein turnover in cultured HCT-116 cells. Treatment of HCT-116 cells with Pevonedistat (MLN4924) for 24 h results in a dose-dependent decrease of Ubc12-NEDD8 thioester and NEDD8-cullin conjugates, with an IC50 [1]. Pevonedistat induces CLL cell apoptosis and circumvented stroma-mediated resistance. Pevonedistat promotes induction of Bim and Noxa in the CLL cells leading to rebalancing of Bcl-2 family members toward the proapoptotic BH3-only proteins[2]. Pevonedistat (MLN4924) rapidly inhibits cullin 1 neddylation and remarkably suppressed growth and survival as well as migration in a dose-and time-dependent manner in gastric cancer cells, and significantly suppresses migration by transcriptionally activating E-cadherin and repressing MMP-9[3].

In Vivo：Pevonedistat (MLN492410, 30 or 60 mg/kg, s.c.) leads to a dose- and time-dependent increase in the steady state levels of NRF2 and CDT1 in HCT-116 tumour-bearing mice, and decreases NEDD8-cullin levels in normal mouse tissue as illustrated in mouse bone marrow cells. Pevonedistat (MLN4924) administered on a BID schedule at 30 and 60 mg/kg inhibits tumour growth with T/C values of 0.36 and 0.15, respectively[1].

Animal Administration：Female athymic NCR mice are used in all in vivo studies. Mice are inoculated with 2×106 HCT-116 cells (or 30-40 mg H522 tumour fragments) subcutaneously in the right flank, and tumour growth is monitored with caliper measurements. When the mean tumour volume reaches approximately 200 mm3, animals are dosed subcutaneously with vehicle (10% cyclodextrin) or Pevonedistat (MLN4924). Inhibition of tumour growth (T/C) is calculated on the last day of treatment.

Cell Assay：HCT-116 cells grown in 6-well cell-culture dishes are treated with 0.1% DMSO (control) or Pevonedistat(MLN4924) for 24 h. Whole cell extracts are prepared and analysed by immunoblotting. For analysis of the E2-UBL thioester levels, lysates are fractionated by non-reducing SDS-PAGE and immunoblotted with polyclonal antibodies to Ubc12, Ubc9 and Ubc10. For analysis of other proteins, lysates are fractionated by reducing SDS-PAGE and probed with primary antibodies as follows: mouse monoclonal antibodies to CDT1, p27, geminin, ubiquitin, securin/PTTG and p53 or rabbit polyclonal antibodies to NRF2, Cyclin B1 and GADD34. Rabbit monoclonal antibodies to NEDD8 and phosphorylated CHK1 (Ser 317) are generated using Ac-KEIEIDIEPTDKVERIKERVEE-amide and Ac-VKYSS(pS)QPEPRT-amide as immunogens, respectively. Antibodies to pH3, cleaved PARP and cleaved caspase 3 are from Cell Signaling Technologies. Secondary HRP-labelled antibodies to rabbit IgG or mouse IgG are used as appropriate. Blots are developed with ECL reagent.
