A rapid and simple HPLC-UV method for the determination of inhibition characteristics of farnesyl transferase inhibitors.

Ras proteins play an important role in the development of cancer. Farnesyl transferase inhibitors (FTIs) block the first obligatory post-translational step for activation, prenylation, of Ras proteins. To find new potent FTIs, rapid enzyme activity assays are required to reduce FTI development time.
