Benzonitrile, 4-[[5-[[4-(3-chlorophenyl)-3-oxo-1-piperazinyl]methyl]-1H-imidazol-1-yl]methyl]-, hydrochloride (1:1)

L-778123 hydrochloride is an inhibitor of FPTase and GGPTase-I with IC50 of 2 nM and 98 nM in enzyme inhibition determination.IC50 value: 2 nM [1]Target: FPTasein vitro: L-778123 can completely inhibit Ki-Ras prenylation. [1] L-778123 as a farnesyltransferase inhibitor can have a good cytotoxic activity as a classic anti-cancer agent. [2]in vivo: In the dog model, L-778123 inhibits HDJ2 prenylation and produces measurable, albeit slight (5%), levels of unprenylatedRap1A in PBMCs. [1]

L-778,123 hydrochloride is the hydrochloride salt of L-778,123. It is a dual inhibitor of FPTase and GGPTase-I (IC50 of 2nM and 98nm, respectively) and exhibits anti-cancer properties. It has a role as an antineoplastic agent, an EC 2.5.1.58 (protein farnesyltransferase) inhibitor, an EC 2.5.1.59 (protein geranylgeranyltransferase type I) inhibitor and a radiosensitizing agent. It contains a L-778,123 (free base).|Farnesyltransferase/Geranylgeranyltransferase Inhibitor L-778,123 is a benzonitrile derivative capable of inhibiting some prenyltransferases. L-778,123 is a dual inhibitor of farnesyl:protein and geranylgeranyl:protein transferases; both enzymes catalyze prenylation of oncoprotein KRAS, a prerequisite step in activation of KRAS in signal transduction pathway of apoptosis. Although this agent was developed in part as an anti-KRAS agent, L-778,123 failed in a Phase I trial to inhibit KRAS, which is associated with many types of solid tumors.
