Geldanamycin from Streptomyces hygroscopicus (C09-0898-210)

λmax 305(MeOH)(Lit.) A benzoquinoid antibiotic that inhibits p60c-src tyrosine kinase and c-myc gene expression in murine lymphoblastoma cells. Geldanamycin has antiproliferative and antitumor effects. Rapidly depletes p185c-erbB2 protein tyrosine kinase in breast carcinoma cells. Binds to HSP90 and disrupts Raf1-HSP90 complex leading to destabilization of Raf1. Inhibits basal and hypoxia-induced expression of c-Jun (IC50 = 75 nM) and abolishes hypoxia-induced increase in c-Jun N-terminal kinase activity. Also known to selectively destabilize mutated p53 protein from a number of breast, leukemia, and prostate cell lines. A benzoquinoid antibiotic that is a potent inhibitor of pp60src tyrosine kinase. Geldanamycin has antiproliferative and antitumor effects. Inhibits basal and hypoxia-induced expression of c-Jun (IC50 = 75 nM) and abolishes hypoxia-induced increase in c-Jun N-terminal Kinase activity. Binds to HSP90 and disrupts raf1-HSP90 complex leading to destabilizing of Raf1. Also destabilizes mutant p53 protein from a number of breast, leukemic, and prostate cell lines. Inhibits c-myc expression in murine lymphoblastoma cells. Approximately ten-fold more potent than herbimycin A.
