Opis

General description

A cell-permeable trihydroxyflavone compound that inhibits androgen receptor peptide, IκBα, and Topoisomerase I SUMOylation in cell-free assays (>90% at 30 µM) by selectively preventing the transfer of SUMO from the E2 thioester to the substrate without affecting SUMO-activating enzyme E1 or E2 Ubc9-SUMO thioester formation. A 6 h pretreatment with 100 µM 2-D08 is shown to effectively inhibit 10 µM CPT- (Camptothecin; Cat. No. 208925) induced cellular Topoisomerase I SUMOylation in breast cancer ZR-75-1 and BT-474 cultures without affecting overall cellular protein ubiquitinations. Anacardic and Ginkgolic Acid (Cat. No. 172050 and 345887, respectively) in comparison, both inhibit E1- SUMO thioester formation instead.
