Descrizione

General description

A cell-permeable, potent inhibitor of protein tyrosine kinases. Inhibits p60^v-src (IC₅₀ = 12 µM) autophosphorylation. Irreversibly binds to the sulfhydryl groups of the kinase. Dose-dependently inhibits PDGF-induced phospholipase D activation (IC₅₀ = 8 µg/ml). Also, reported to inhibit c-src related bone resorption (IC₅₀ = 70 nM). Inhibits angiogenesis in chick chorioallantoic membrane and blocks anti-CD3 monoclonal antibody-induced apoptosis of thymocytes. Several mammalian cell lines transformed with tyrosine kinase oncogenes (src, abl, fps, ros, yes, erbB) show reversion from the transformed to the normal phenotype after treatment with herbimycin A.
