2107790 9218465 PCTABS00016 The invention features a compound of the formula W-Y-Q-Z or W-Y-Zwherein W is a farnesyl group, a geranylgeranyl group, a substituted farnesyl group or a substituted geranylgeranyl group; Y is (1); Q is (2), wherein n = 1, 2, 3, 4, 5, or 6; each of T1' ... Tn' and T1" ... Tn" is independently: Fl, Br, -NHCOCH3, -NH2, a peptide, an alkane group, an alkene group, a polyethyleneglycol group, a saturated fatty acid, an unsaturated fatty acid, a monosaccharide, or a disaccharide; and Z is -COOH or salts or esters thereof, -CONH2, -NO2, -PO3 or salts or esters thereof, -C N, or -SO3 or salts or esters thereof, provided that when W is farnesyl, Y is -S-, n = 2, and either T2' or T2" is -NHCOCH3, then Z is not -COOH. The compounds of the invention are capable of interfering with enzymatic methylation of a peptide having the carboxyl-terminal motif -CAAX wherein C = cysteine, A = aliphatic amino acid, and X = any amino acid.
