General description

A cell-permeable triazolo-farnesylthiopropanoate compound that acts as a potent, reversible, and isoprenyl mimetic competitive inhibitor of isoprenylcysteine carboxyl methyltransferase activity (ICMT; IC50 = 800 nM; Ki = 400 nM). Shown to prevent K-Ras membrane localization in GFP-K-Ras transfected Jurkat T-cells. Exhibits selective toxicity towards wt-Icmt+/+ mouse embryonic fibroblasts (MEFs) over Icmt-/- MEFs (IC50 = 33 and >100 µM). Also shown to arrest the proliferation of PaTu-8902, a highly metastatic pancreatic cancer cells (IC50 = 8 µM).
