microM), a bisubstrate analog involving anchorage of farnesyl and tripeptide groups by a hydroxamic acid-embedded linker. Starting from 16, a 1 order of magnitude improvement in in vitro potency was obtained by optimization of the linker (20, I50 = 4.35 microM). An additional 13-fold enhancement was achieved by substituting the tripeptidemoiety VLS in 20 by VVM (23, I50 = 0.33 microM). The dependence of
