Would you like email updates of new search results? Because a bisphosphonate group mimics the structure of pyrophosphate, it can inhibit activation of enzymes that utilize pyrophosphate. In recent years, substantial progress has been made in understanding the mechanism for bisphosphonate suppression of bone turnover.

Fiani ML, Barreca V, Sargiacomo M, Ferrantelli F, Manfredi F, Federico M. Int J Mol Sci. Clodronate also treats the weakening in the bones when cancer has spread to the bones from another part of the body. We found that AppCCl(2)p inhibits mitochondrial oxygen consumption by a mechanism that involves competitive inhibition of the ADP/ATP translocase. 8 It has a wide therapeutic index as a large overdose is required for significant toxicity and a long duration of action due to the slow release from bone.

World J. Gastrointest. The known mechanism of action differs from that of the later nitrogen-containing bisphosphonates, as clodronate is metabolised intracellularly to a toxic analog of adenosine triphosphate, AppCCl2p, which causes mitochondrial dysfunction, impaired cellular energy metabolism and osteoclast apoptosis. Clodronate, alendronate, and other bisphosphonates are widely used in the treatment of bone diseases characterized by excessive osteoclastic bone resorption. Drug action For all BISPHOSPHONATES .

Clodronate can reduce the incidence and number of new bony and visceral metastases in women with breast cancer who are at high risk for distant metastases. Please enable it to take advantage of the complete set of features! The reason of its activity is the anti-resorptive action, which is a common characteristic of BPs. | We addressed this question by studying the effects of alendronate, clodronate, and the clodronate metabolite AppCCl(2)p on isolated mitochondria, mitochondrial fractions, and mitochondrial membrane potential in isolated human osteoclasts. Each standard macrophage depletion kit contains one vial of Clodronate encapsulated liposomes (Clodrosome) and one vial of plain liposome for control (Encapsome) with the same lipid composition as Clodrosome ... macrophage depletion technique, the mechanism of action of clodrosome, and proper administration techniques. 6 (7), 122 ± 128. Epub 2011 May 1. Simple bisphosphonates such as clodronate and etidronate inhibit bone resorption through induction of osteoclast apoptosis. Mechanism of action After Clodrosome® has been dosed to the animal by the chosen route, the clodronate liposomes will come into contact with macrophages and other phagocytic cells. Bisphosphonates are structurally similar to pyrophosphate, but with a central carbon that can have up to two substituents (R 1 and R 2) instead of an oxygen atom. Bisphosphonates are currently the most important class of antiresorptive drugs used for the treatment of diseases with excess bone resorption. USA.gov. eCollection 2020. The detailed molecular basis for the cytotoxic effects of adenosine-5'-[beta,gamma-dichloromethylene]triphosphate (AppCCl(2)p) has not been determined yet.
