Abstract
Farnesyl diphosphate (FPP) analogues have proven to be both potent inhibitors of protein-farnesyltransferase (FTase) and valuable probes for the investigation of the function of prenylated proteins. Previously, we have demonstrated that certain 3-substituted and 7-substituted FPP analogues can act as inhibitors of FTase, while others are effective alternative substrates. We have now utilized our vinyl triflate-mediated route to synthesize the first seven FPP variants bearing substituents in both the 3- and 7-positions of the isoprene unit. Despite their exceptional steric bulk with respect to FPP itself, six of the seven analogues bind to FTase. Two of the analogues are potent inhibitors of the enzyme, but a more striking finding is that three FPP variants (4a, 4b, and 4f) are efficient alternative substrates for FTase.

Abstract
The Suzuki coupling reaction has been used to introduce a methyl group derived from commercially available methylboronic acid into a vinyl triflate. This has led to a concise synthesis of all-trans-geranylgeraniol, with the key step being the palladium-catalyzed, silver-mediated methylation of triflate to give ethyl geranylgeranoate. This coupling protocol has also been used to produce the novel geranylgeranyl diphosphate (GGPP) analogue 3-phenyl-3-desmethylgeranylgeranyl diphosphate (3-PhGGPP, ). Our previously developed organocuprate coupling protocol has been used to introduce the cyclopropyl and tert-butyl moieties into the 3-position of vinyl triflate. The four GGPP analogues 3-vinyl-3-desmethylgeranylgeranyl diphosphate (3-vGGPP, ), 3-cyclopropyl-3-desmethylgeranylgeranyl diphosphate (3-cpGGPP, ), 3-tert-butyl-3-desmethyl-geranylgeranyl diphosphate (3-tbGGPP, ), and were then evaluated as potential inhibitors of recombinant yeast protein-geranylgeranyl transferase I (PGGTase I). The potential mechanism-based inhibitors 3-vGGPP and 3-cpGGPP did not exhibit time-dependent inactivation of PGGTase I. Instead, both analogues were alternative substrates, in accord with the interaction of the corresponding farnesyl analogues 3-vFPP and 3-cpFPP with PFTase. The tert-butyl and phenyl analogues were not substrates, but were instead competitive inhibitors of PGGTase I. Note that all four of the GGPP analogues were bound less tightly by the enzyme than the natural substrate, in contrast to the behavior of the 3-substituted FPP analogues.

Abstract
The novel farnesyl diphosphate (FPP) analog 3-cyclopropyl-3-desmethylfarnesyl diphosphate (3-cpFPP, 1) was designed as a potential mechanism-based inhibitor of the FPP-utilizing enzyme protein-farnesyl transferase (PFTase). The key step in the synthesis of 1 involved the stereoselective coupling of vinyl triflate 8 with a lower order cyclopropyl cyanocuprate to afford the desired cyclopropyl ester 13. The sterically encumbered analog 3-desmethyl-3-tert-butylfarnesyl diphosphate (3-tbFPP, 7) was synthesized via a similar route. The use of the more reactive higher order tert-butyl cyanocuprate led to lower yields of ester 11, the key intermediate in the synthesis of 7. Biological evaluation of 3-cpFPP demonstrates that it is not a time-dependent inhibitor of recombinant yeast PFTase. Instead, 3-cpFPP is an alternative substrate for this enzyme that exhibits a K(m) comparable to FPP and a k(cat) only 5-fold lower than the natural substrate. In contrast, 3-tbFPP is an exceptionally poor substrate for yeast PFTase and acts as an inhibitor of this enzyme.
