Risedronic acid Usage And Synthesis
UsesRisedronic Acid is a pyridinyl biphosphonate bone resorption inhibitor. It is a potentially useful biophosphonate for bone resorption analysis.
DefinitionChEBI: Risedronic acid is a member of pyridines. It is a third generation bisphosphonate that is used for the treatment of some forms of osteoperosis and Paget's disease. It functions by preventing resorption of bone.
Mode of actionRisedronatic acid binds to bone hydroxyapatite. Bone resorption causes local acidification, releasing risedronic acid which is that taken into osteoclasts by fluid-phase endocytosis. Endocytic vesicles are acidified, releasing risedronic acid to the cytosol of osteoclasts where they induce apoptosis through inhbition of farnesyl pyrophosphate synthase. Inhibition of osteoclasts results in decreased bone resorption.
