WebBiological Activity. Potent farnesyl transferase inhibitor (IC50 = 1.9 nM). Inhibits farnesylation of RAS. Also inhibits Pgp transport (IC50 < 3 μM) and increases potency and anticancer activity when used in conjunction with cytotoxic Pgp substrates. Inhibits neovascularization by affecting cell motility. Orally bioavailable. WebThe synthesis of ras farnesyl-protein transferase inhibitor 1 is described on a multi-kilogram scale. Retrosynthetic analysis reveals chloromethylimidazole 2 and a piperazinone 3 as viable precursors. The 1,5-disubstituted imidazole system was regioselectively assembled via an improved Marckwald imidazole synthesis. A new imidazole dethionation procedure …
WebApr 24, 2024 · We used two different inhibitors, FTI-277 and manumycin A, as they target farnesylation in different ways: FTI-277 is a CAAX peptidomimetic which competes with target proteins for the binding of farnesyl residues, whereas manumycin A is a farnesyl pyrophosphate analogue which competes with farnesyl pyrophosphate at the farnesyl … WebFarnesyltransferase Inhibitors. Farnesylation is one of the important steps in the posttranslational modification of proteins associated with intracellular signal transduction. 382 The process is catalyzed by a heterodimeric zinc protein known as farnesyltransferase and involves the transfer of a farnesyl group from farnesyl pyrophosphate to ...
WebProtein farnesylation is a lipid posttranslational modification required for the cancer-causing activity of proteins such as the GTPase Ras.
