S-Farnesyl thioacetic acid is an analog of S-farnesyl cysteine which behaves as a competitive inhibitor of isoprenylated protein methyltransferase (also known as S-adenosylmethionine-dependent methyltransferase). It can also inhibit methylation of both farnesylated and geranylgeranylated substrates.
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.
BPH-1358 (NSC50460) free base is a potent human undecaprenyl diphosphate synthase (UPPS) and farnesyl diphosphate synthase (FPPS) inhibitor (IC50s: 110 nM and 1.8 μM) and is active against S. aureus in vitro (MIC ~250 ng mL).
