Nitrile-containing macrolide antibiotic produced by Streptomyces species which inhibits bacterial and eukaryal threonyl-tRNA synthetase (THrRS). Displays pronounced antiangiogenic activity (IC50 = 0.8 nM) and also induces the collapse of formed capillary tubes in a dose-dependent fashion. In HUVECs, the capillary tube collapsing activity is mediated by the activation of caspases-3 and –8 and induction of apoptosis. The IC50 for antiangiogenic activity is 50-fold lower that that for THrRS inhibition indicating the possibility for an alternate molecular target. Was shown to be highly effective in blocking the formation of spontaneous lung metastases of B16-BL6 melanoma cells at the same dosage that inhibited angiogenesis. Inhibitor of cyclin-dependent kinase (CDK). Shows antiviral activity.
