nitrogen-containing bisphosphonates (such as pamidronate, alendronate, risedronate, ibandronate and zoledronate) appear to act as analogues of isoprenoid diphosphate lipids, thereby inhibiting farnesyl pyrophosphate (fpp) synthase, an enzyme in the mevalonate pathway. inhibition of this enzyme in osteoclasts prevents the biosynthesis of isoprenoid lipids (fpp and ggpp) that are essential for the post-translational farnesylation and geranylgeranylation of small gtpase signalling proteins.
