title: Synthesis of NO-donor bisphosphonates and their in-vitro action on bone resorption.
abstract: A new class of bisphosphonates containing nitrooxy NO-donor functions has been developed. The products proved to display affinity for hydroxyapatite. Injection of (99m)Tc-labeled derivatives 11 and 18 into male rats showed a preferential accumulation of the compounds in bone as compared to blood and muscles. The products were found to inhibit the differentiation of pre-osteoclasts to functional osteoclasts induced by receptor activator of NF-kappaB ligand (RANKL), through a prevalent NO-dependent mechanism.
