Chemical Name: [1-[[1-[(4-Bromophenyl)methyl]-1H-imidazol-5-yl]methyl]-4-(1-naphthalenyl)-1H-pyrrol-3-yl]-4-morpholinylmethanone

Biological Activity

Selective inhibitor of farnesyltransferase (FTase). Blocks farnesylation of H-Ras, N-Ras and K-Ras4B (IC50 values are 0.8, 1.2 and 2.0 nM respectively). Displays >50,000-fold selectivity for FTase over geranylgeranyltransferase (GGTase) I. Inhibits VEGF-induced Ras activation; suppresses angiogenesis in vivo and in vitro (IC50 = 75 nM). Orally active.

Technical Data

Soluble to 100 mM in DMSO and to 100 mM in ethanol
>98 %
Desiccate at RT
