A stereocontrolled synthetic route has been used to prepare two of the geometric isomers of all-trans-GGPP. Neither of these isomers is effective substrates for mammalian GGTase I, but 3 is a potent inhibitor of this enzyme (IC50 = 100 nM). Surprisingly, both compounds are effective substrates for mammalian FTase. (C) 2001 Elsevier Science Ltd. All rights reserved.

Two di-C-13-labeled farnesyl diphosphates (2 and 4) have been prepared using modified versions of the isoprenoid triflate route previously developed in this laboratory. The (3)J(CC) coupling constants far the precursor alcohols 1 and 3 are 1.6 Hz and 3.6 Hz, respectively, in CDCl3, and very similar results were obtained for 2 and 4 in D2O. This indicates a skew or gauche conformation about the C-3-C-4 bond and a trans conformation about the C-4-C-5 bond in both farnesol and FPP. (C) 1998 Elsevier Science Ltd. All rights reserved.

group is required for fullbiologicalactivity. This peptide has been used as a model system to explore the biological function of the farnesylcysteine moiety, which is found on and required for the biologicalactivity of many key mammalian proteins. The objective of this particular study was the determination of the biological effect of double bond isomerization of the natural E, E-farnesyl moiety
