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.
