Isoprenoid-substituted bisphosphonates are recognized to serve as inhibitors from the enzyme

Isoprenoid-substituted bisphosphonates are recognized to serve as inhibitors from the enzyme geranylgeranyl diphosphate synthase, and their activity could be extremely delicate to olefin stereochemistry. 13 (685 mg, 89%) like a yellowish oil.
