Clodronate (CLO) is a bisphosphonate (BP) with proved efficacy in the treatment of osteoporosis. Hence, inhibition of the ADP/ATP translocase by the metabolite AppCCl(2)p is a likely route by which clodronate causes osteoclast apoptosis and inhibits bone resorption. 1996; 50: 1127–1138. Julie C. Frith. Curr Pharm Des. NLM  |  The mechanism of action of bisphosphonates has not been fully elucidated. NIH Bone. 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. Of all of the BPs, clodronate is by far the strongest inhibitor of VNUT, even when compared with other non-NBPs, such as tiludronate. Annu Rev Pharmacol Toxicol. eCollection 2020.

Hearts in Healthcare . Clodronate also treats the weakening in the bones when cancer has spread to the bones from another part of the body. Recent studies have shown that bisphosphonates can be divided into two groups with distinct molecular mechanisms of action depending on the nature of the R(2) side chain. Further Insight into Mechanism of Action of Clodronate: Inhibition of Mitochondrial ADP/ATP Translocase by a Nonhydrolyzable, Adenine-Containing Metabolite | … We found that AppCCl(2)p inhibits mitochondrial oxygen consumption by a mechanism that involves competitive inhibition of the ADP/ATP translocase. Bisphosphonates can now be distinguished based on their molecular and cellular mechanisms of action. Int J Nanomedicine. 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. The aim of this study is to compare the efficacy and safety between zoledronic acid (ZA) and clodronate (CA) in the treatment of bone metastases for prostate cancer patients. J Bone Miner Res. Would you like email updates of new search results? The reason of its activity is the anti-resorptive action, which is a common characteristic of BPs. Liposomes, encapsulating the Clodronate molecules (squares), are ingested by macrophages via endocytosis. Studies on the mechanisms of action of this molecule on bone metabolism have been limited and only recently has information on the molecular machinery that underlies its effects on the bone remodelling process become available. 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.  |  : – Van Rooijen, N., & Sanders, a advanced features are temporarily unavailable Regulate...

The molecular mechanism of action of the antiresorptive and antiinflammatory drug clodronate: evidence for the formation in vivo of a metabolite that inhibits bone resorption and causes osteoclast and macrophage apoptosis. Alendronate, like other nitrogen-containing bisphosphonates, inhibits bone resorption and causes apoptosis of osteoclasts and other cells in vitro by preventing post-translational modification of GTP-binding proteins with isoprenoid lipids. Clodronate (CI2MBP) is a non-aminated bisphosphonate that inhibits bone resorption. endstream endobj startxref 2963. of clodronate and etidronate29 and is of similar anti-resorptive potency to clodronate in vivo. 4 The first pyrophosphate-like bisphosphonates (such as etidronate and clodronate) are incorporated into adenosine triphosphate (ATP), a source of energy in the cell. The relationship between molecular action and antiresorptive effects has been documented for BPs lacking and containing nitrogen.

Request PDF | Clodronate: Old Drug, New Uses | Clodronate (CLO) is a bisphosphonate (BP) with proved efficacy in the treatment of osteoporosis. Liposome mediated depletion of macrophages: mechanism of action, preparation of liposomes and applications. In addition to antiresorptive activity, clodronate has shown anti-inflammatory and analgesic properties, and modulatory effects on bone and cartilage metabolism. When comparing effects of clodronate liposomes with PBS liposomes, the effects can therefore be less than expected. 1997 Sep;12(9):1358-67. doi: 10.1359/jbmr.1997.12.9.1358. The more concentric bilayers are disrupted, the greater is the Clodronate release within the cell. The exact mechanisms of action of bisphosphonates have not been identified but may involve a toxic effect on mature osteoclasts due to the induction of apoptosis. Clodronate, alendronate, and other bisphosphonates are widely used in the treatment of bone diseases characterized by excessive osteoclastic bone resorption. The phagocyte immediately recognizes the liposomes as foreign particles and proceeds with destroying these invading particles. New insights into molecular mechanisms of bisphosphonate action The molecular mechanisms by which these effects on osteoclasts are produced are currently being unravelled. Is the keto diet for you?

The molecular mechanism of action of the anti-resorptive and anti-inflammatory drug clodronate: evidence for the formation in vivo of a metabolite that inhibits bone resorption and causes osteoclast and macrophage apoptosis. 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.

Crossref Medline Google Scholar; 8 Selander K, Monkkonen J, Karhukorpi E, et al. Patients or carers should be given advice on how to administer sodium clodronate capsules and tablets. Clodronate (CLO) is a bisphosphonate (BP) with proved efficacy in the treatment of osteoporosis. Hence, inhibition of the ADP/ATP translocase by the metabolite AppCCl(2)p is a likely route by which clodronate causes osteoclast apoptosis and inhibits bone resorption. 1996; 50: 1127–1138. Julie C. Frith. Curr Pharm Des. NLM  |  The mechanism of action of bisphosphonates has not been fully elucidated. NIH Bone. 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. Of all of the BPs, clodronate is by far the strongest inhibitor of VNUT, even when compared with other non-NBPs, such as tiludronate. Annu Rev Pharmacol Toxicol. eCollection 2020.

Hearts in Healthcare . Clodronate also treats the weakening in the bones when cancer has spread to the bones from another part of the body. Recent studies have shown that bisphosphonates can be divided into two groups with distinct molecular mechanisms of action depending on the nature of the R(2) side chain. Further Insight into Mechanism of Action of Clodronate: Inhibition of Mitochondrial ADP/ATP Translocase by a Nonhydrolyzable, Adenine-Containing Metabolite | … We found that AppCCl(2)p inhibits mitochondrial oxygen consumption by a mechanism that involves competitive inhibition of the ADP/ATP translocase. Bisphosphonates can now be distinguished based on their molecular and cellular mechanisms of action. Int J Nanomedicine. 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. The aim of this study is to compare the efficacy and safety between zoledronic acid (ZA) and clodronate (CA) in the treatment of bone metastases for prostate cancer patients. J Bone Miner Res. Would you like email updates of new search results? The reason of its activity is the anti-resorptive action, which is a common characteristic of BPs. Liposomes, encapsulating the Clodronate molecules (squares), are ingested by macrophages via endocytosis. Studies on the mechanisms of action of this molecule on bone metabolism have been limited and only recently has information on the molecular machinery that underlies its effects on the bone remodelling process become available. 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.  |  : – Van Rooijen, N., & Sanders, a advanced features are temporarily unavailable Regulate...
