Inhibition of farnesyl pyrophosphate (FPP) and/or geranylgeranyl pyrophosphate (GGPP) biosynthesis and its implication in the treatment of cancers

AbstractDysregulation of isoprenoid biosynthesis is implicated in numerous biochemical disorders that play a role in the onset and/or progression of age-related diseases, such as hypercholesterolemia, osteoporosis, various cancers, and neurodegeneration. The mevalonate metabolic pathway is responsible for the biosynthesis of the two key isoprenoid metabolites, farnesyl pyrophosphate (FPP) and geranylgeranyl pyrophosphate (GGPP). Post-translational prenylation of various proteins, including the small GTP-binding proteins (GTPases), with either FPP or GGPP is vital for proper localization and activation of these proteins. Prenylated GTPases play a critical role in cell signaling, proliferation, cellular plasticity, oncogenesis, and cancer metastasis. Pre-clinical and clinical studies strongly suggest that inhibition of protein prenylation can be an effective treatment for non-skeletal cancers. In this review, we summarize the most recent drug discovery efforts focusing on blocking protein farnesylation and/...
