α-hydroxy Farnesyl Phosphonic Acid is a non-hydrolyzable analog of farnesyl pyrophosphate which acts as a competitive inhibitor of Farnesyl Transferase (FPTase). α-hydroxy Farnesyl Phosphonic acid inhibits the processing of Ras in Ha-ras-transformed NIH3T3 cells at concentrations greater than 1 μM.
