TNP-470 - CAS 129298-91-5 - Calbiochem,AGM-1470, O-(Chloroacetyl-carbamoyl)fumagillol, AGM1470, MetAP-2 Inhibitor II, MetAP2 Inhibitor II, Methionine Aminopeptidase 2 Inhibitor II, TNP470

一般描述

A cell-permeable Fumagillin (Cat. No. 344845) analog that inhibits MetAP2, but not MetAP1, methionine aminopeptidase activity (IC50 = 1 nM against human MetAP2) by covalently modifying MetAP2 active site histidine (aa 231 in human/mouse/rat; aa 174 in yeast) via its epoxide group, without affecting the inhibitory activity of MetAP2 against HRI- (heme-regulated inhibitor kinase) catalyzed eIF-2α phosphorylation. Cellular MetAP2 inhibition is particularly effective in inducing endothelial cytostasis (IC50 = 25 pM and 37 pM, respectively, against HUVEC and bovine BAEC proliferation by TNP-470), making TNP-470 a potent anti-angiogenesis agent in vivo (2 to 100 mg/kg in mice and rats; s.c.). Reported to be more potent and less toxic than Fumagillin. A cell-permeable Fumagillin (Cat.
