Enzo Life Sciences Radicicol (1mg). CAS: 12772-57-5
Antifungal macrocyclic lactone antibiotic with antimalarial activity. Potent inhibitor of HSP90. Binds more strongly to HSP90 (nanomolar affinity) than to Grp94. Also binds to yeast HSP90, E. coli HtpG and TRAP-1. Non-competitive inhibitor of ATP citrate lyase. Anti-angiogenic. Specifically inhibits the interaction between HIF-1α/Arnt heterodimer and the hypoxia-responsive element (HRE), reducing VEGF expression. Protein tyrosine kinase inhibitor, e.g. p60v-src (IC50=0.27nM). Inhibitor of cyclooxygenase-2 (COX-2) expression (IC50=27nM) without affecting COX-1 expression in LPS-stimulated macrophages. Induces the differentiation of HL-60 cells into macrophages, blocking cell cycle at G1 and G2. Suppressor of NIH 3T3 cell transformation by diverse oncogenes such as mos, ras and src in part by blocking the key signal transduction intermediates such as MAP kinase and GAP-associated p62. Purity: ≥97% (HPLC). Solubility: Soluble in DMSO, methanol or acetone. Long Term Storage: -20°C.
