  Probing the hydrophobic pocket of farnesyltransferase: aromatic substitution of CAAX peptidomimetics leads to highly potent inhibitors

  摘要：

  Cysteine farnesylation at the carboxylate terminal tetrapeptide CAAX of Ras protein is catalyzed by farnesyltransferase. This lipid modification is necessary for regulatory function of both normal and oncogenic Ras. The high frequency of Ras mutation in human cancers has prompted an intensive study on finding ways of controlling oncogenic Ras function. Inhibition of farnesyltransferase is among the most sought after targets for cancer chemotherapy. We report here the design, synthesis and biological characterization of a series of peptidomimetics as farnesyltransferase inhibitors. These compounds are extremely potent towards farnesyltransferase with IC50 values ranging from subnanomolar to low nanomolar concentrations. They have a high selectivity for farnesyltransferase over the closely related geranylgeranyltransferase-I. Structure-activity relationship studies demonstrated that a properly positioned hydrophobic group significantly enhanced inhibition potency, reflecting an improved complementarity to the large hydrophobic pocket in the CAAX binding site.

  Mimetics of the C-terminal CAAX tetrapeptide of Ras protein were designed as farnesyltransferase (FTase) inhibitors (FTIs) by replacing AA with o-aryl or o-heteroaryl substituted p-hydroxy- or p-aminobenzoic acid, while maintaining the replacement of C with 1,4-benzodioxan-2-ylmethyl or 2-amino-4-thiazoly-lacetyl residue as in previous CAAX mimetics. Both FTase inhibition and antiproliferative effect were showed by two thiazole derivatives, namely those with 1-naphthyl (10 and 10a) or 3-furanyl (15 and 15a) in the central spacer, and by the benzodioxane derivative with 2-thienyl (6 and 6a) in the same position. Accumulation of unprenylated RAS was demonstrated in cells incubated with 15a. Consistently with FTIs literature, such results delineate the biaryl scaffold not only as a spacer but also as a sensible area of these mimetic molecules, where modifications at the branching aromatic ring are not indifferent and should be matter of further investigation.
