      Abstract:

        Human   isoprenylcysteine carboxyl methyltransferase (hIcmt) is a   promising anticancer target as it is important for the   post-translational modification of oncogenic   Ras proteins. We herein report the synthesis and   biochemical activity of 41 farnesyl-cysteine  based analogs versus hIcmt. We have demonstrated that the amide   linkage of a hIcmt substrate can be replaced by a sulfonamide   bond to achieve hIcmt inhibition. The most potent   sulfonamide-modified farnesyl   cysteine analog was 6ag with an   IC50 of 8.8 ± 0.5 μM for hIcmt.
