Amide-substituted farnesylcysteine analogs as inhibitors of human isoprenylcysteine carboxyl methyltransferase.
N-Acetyl-S-farnesyl-L-cysteine (AFC) is the minimal substrate for the enzyme isoprenylcysteine carboxyl methyltransferase (Icmt). A series of amide-modified farnesylcysteine analogs were synthesized and screened against human Icmt. From a 23-membered library of compounds, six inhibitors were identified and evaluated further. The adamantyl derivative 7c was the most potent inhibitor with an IC(50) of 12.4 microM.
