Compounds used to treat cancer which inhibit carboxy terminal proteolysis of proteins having a carboxyl-terminal -CAAX motif (C=cysteine, A=aliphatic amino acid, and X=any amino acid). The compounds have the formula W--Y--CH.sub.2 --Q, where: 1) W is a substituted or unsubstituted farnesyl group, a substituted or unsubstituted geranylgeranyl group, or a lipophilic alkyl, alkenyl, aryl or arylalkyl hydrocarbon group; 2) Y is: ##STR1## wherein T.sub.1 is: --H, --CH.sub.3, --F, or --(CH.sub.2).sub.n --X.sub.1 ; in which n is an integer <20; and X.sub.1 is: --SH, --COOH, or --CONH.sub.2 ; T.sub.2 is: --N-benzxyloxycarbonyl (Boc), N--.phi.--, in which .phi. is an amino acid or a polypeptide reside; and ##STR2## wherein X.sub.2 is a peptide residue linked to carbon via the amino terminal nitrogen; and X.sub.3 is a peptide residue linked via an alpha carbon of the peptide; n is an integer <20, X.sub.4 is a halide and .beta. is an amino acid residue.
