alpha-Hydroxy farnesyl phosphonic acid
α-hydroxy Farnesyl phosphonic acid is a nonhydrolyzable analog of farnesyl pyrophosphate which acts as a competitive inhibitor of farnesyl transferase (FTase). At concentrations greater than 1 μM, α-hydroxy farnesyl phosphonic acid inhibits the processing of Ras in Ha-ras-transformed NIH3T3 cells.
