Product information "PYR41"
PYR41 is an irreversible inhibitor of ubiquitin-activating enzyme (E1) with an IC50 value of less than 10 µM. PYR41 specifically inhibits ubiquitin-thioester bond formation (IC50 = 6.4 µM) and not adenylation. It is selective for E1 over ubiquitin-conjugating enzyme (E2) but does inhibit autoubiquitination of the HECT domain ubiquitin protein ligase (E3) Nedd4 at a concentration of 50 µM in an autoubiquitination assay. It inhibits proteasome-dependent and -independent ubiquitination and protein degradation when used at a concentration of 50 µM. PYR41 prevents activation of NF-kappaB, ubiquitination of TNF receptor-associated factor 6 (TRAF6), and proteasomal degradation of IkappaBalpha. It prevents degradation and induces transcriptional activity of the tumor suppressor p53 and preferentially induces apoptosis of E1A-transformed RPE cells expressing wild-type p53 over non-transformed RPE cells when used at concentrations ranging from 1 to 20 µM. PYR41 also increases net cellular sumoylation and irreversibly cross-links proteins such as JAK2 and Bcr-Abl.Formal Name: 4-[4-[(5-nitro-2-furanyl)methylene]-3,5-dioxo-1-pyrazolidinyl]-benzoic acid, ethyl ester.
