Farnesyl pyrophosphate is an intermediate in the HMG-CoA reductase pathway and used in the biosynthesis of terpenes, terpenoids, and sterols. It also serves as a donor in post-translational isoprenylation of proteins. FPP has been identified as an antagonist of P2Y12 receptors (IC50 = 45 μM), attenuating platelet aggregation. It has also been shown to regulate adipocyte function as an endogenous PPARγ agonist. Additionally, because of a flexible hydrocarbon chain that enables different conformations, FPP is a promiscuous ligand for a subset of nuclear receptors.
