Pevonedistat Usage And Synthesis

Description

MLN4924 (905579-51-3) is a potent and selective NEDD8-activating enzyme (NAE) inhibitor.1?It disrupts cullin-RING ligase-mediated protein turnover leading to apoptosis in human tumor cells. Suppresses the growth of human tumor xenografts in mice.2?Upregulates PD-L1 expression and enhances the efficacy of immune checkpoint blockade in glioblastoma.3?Modulates tumor microenvironment.4?Cell permeable.

Chemical Properties

White Solid

Uses

A potent and selective inhibitor of NAE. An inhibitor of NEDD8-activating enzyme as a new approach to treat cancer. The ubiquitin-proteasome pathway mediates the destruction of unwanted proteins. Potent NAE inhibitor; NEDD8 E1 Activating Enzyme Inhibitor.

Definition

ChEBI: Pevonedistat is a pyrrolopyrimidine that is 7H-pyrrolo[2,3-d]pyrimidine which is substituted by a (1S)-2,3-dihydro-1H-inden-1-ylnitrilo group at position 4 and by a (1S,3S,4S)-3-hydroxy-4-[(sulfamoyloxy)methyl]cyclopentyl group at position 7. It is a potent and selective NEDD8-activating enzyme inhibitor with an IC50 of 4.7 nM, and currently under clinical investigation for the treatment of acute myeloid leukemia (AML) and myelodysplastic syndromes. It has a role as an apoptosis inducer and an antineoplastic agent. It is a pyrrolopyrimidine, a secondary amino compound, a member of cyclopentanols, a sulfamidate and a member of indanes.

Enzyme inhibitor

This first-in-class small molecule inhibitor (FW = 443.52 g/mol; CAS 905579-51-3; Solubility = 10 mg/mL DMSO), also named MLN4924 and [(1S,2S,4R)-4-[4-[[(1S)-2,3-dihydro-1H-inden-1-yl]amino]-7H-pyrrolo[2,3- d]pyrimidin-7-yl]-2-hydroxycyclopentyl]sulfamate methyl ester, targets Nedd8 activating enzyme, or NAE (IC50 = 4.7 nM), with much weaker action against UAE (IC50 = 1.5 μM), SAE (IC50 = 8.2 μM), and UBA6 (IC50 = 1.8 μM). In most cancer cells, pevonedistat treatment results in the induction of DNA re-replication, resulting in DNA damage and cell death. MLN4924 also exhibits an alternative mechanism of action. Treatment of activated B cell-like (ABC) diffuse large B-cell lymphoma (DLBCL) cells with pevonedistat resulted in rapid accumulation of pIkBa, decrease in nuclear p65 content, reduction of transcriptional activity of NF-kB (or nuclear factor k-light-chain-enhancer of activated B cells), and G1 arrest, ultimately resulting in apoptosis induction, events consistent with potent NF-kB pathway inhibition. Treatment of germinal-center B cell-like (GCB) DLBCL cells resulted in an increase in cellular Cdt-1 and accumulation of cells in S-phase, consistent with cells undergoing DNA rereplication. Pevonedistat also inhibits Vpx/Vpr-induced SAMHD1 degradation by inhibiting the neddylation of E3 ubiquitin-ligase and blocking SIVmac replication in myeloid cells, therebyindicating the potential efficacy of inhibiting neddylation as an antiretroviral strategy
