Mutant RAS proteins are associated with 30% of all human cancers. Unregulated cell growth caused by mutant RAS proteins can be prevented by RAS farnesyl protein transferase (FPTase) inhibitors. A novel FPTase inhibitor has been synthesized incorporating a modified farnesyl “tail” and a customized diphosphate “head”. It is anticipated that the modified “tail”, incorporating a phenyl substituent, will bind more tightly to FPTase due to nonbonding interactions between the aromatic ring and ten aromatic amino acid residues that line the enzyme active site. The altered polar “head”, designed from L-aspartic acid, has already been shown to mimic the natural substrate’s …
