产品信息 CAS number 1258004-00-0 Storage -20°C Form White solid Primary Target 20S proteasome (MCP; multicatalytic proteinase complex) Secondary target NF-κB activation (IC50 = 10 µM) Purity Purity by HPLC. Chemical formula C15H24N2O7S An irreversible proteasome inhibitor. A Streptomyces metabolite that acts as a highly specific inhibitor of the 20S proteasome (MCP; multicatalytic proteinase complex) (IC50 = 500 nM for 20S proteasome). Blocks proteasome activity by targeting the catalytic β-subunit. Acts as a covalent inhibitor of the chymotrypsin- and trypsin-like activities of the proteasome. Induces neurite outgrowth in Neuro 2A mouse neuroblastoma cells and inhibits progression of synchronized Neuro 2A cells and MG-63 human osteosarcoma cells beyond the G1 phase of the cell cycle. Reported to induce apoptosis in human monoblast U937 cells. Also inhibits NF-κB activation (IC50 = 10 µM).
