Liposomes, encapsulating the Clodronate molecules (squares), are ingested by macrophages via endocytosis. A new endogenous ATP analog (ApppI) inhibits the mitochondrial adenine nucleotide translocase (ANT) and is responsible for the apoptosis induced by nitrogen-containing bisphosphonates. 1997 Sep;12(9):1358-67. doi: 10.1359/jbmr.1997.12.9.1358.

Because of its mechanism of action, clodronate inhibits vesicular nucleotide transporter (VNUT), a key molecule carrying ATP as part of pathologic nociception. 6 (7), 122 ± 128. 2003;9(32):2643-58. doi: 10.2174/1381612033453640. We conducted a prospective study in recruiting 137 prostate cancer patients with bone metastases from 2008 to 2010. 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. 2020 Oct 7;11:583647. doi: 10.3389/fimmu.2020.583647. World J. Gastrointest. Clodronate also treats the weakening in the bones when cancer has spread to the bones from another part of the body. Bisphosphonates are currently the most important class of antiresorptive drugs used for the treatment of diseases with excess bone resorption. Arthritis Rheum. Contrary to other BPs, CLO has a relatively low affinity for bone and a peculiar mechanism of action. MECHANISM OF ACTION: Clodronate is a first -generation bisphosphonate, which inhibits bone resorption. When comparing effects of clodronate liposomes with PBS liposomes, the effects can therefore be less than expected. The mechanism of action of bisphosphonates has not been fully elucidated. The more concentric bilayers are disrupted, the greater is the Clodronate release within the cell. Curr Pharm Des. Nanotechnology-Based Targeting of mTOR Signaling in Cancer. University of … 2. Is the keto diet for you? Contrary to other BPs, CLO has a relatively low affinity for bone and a peculiar mechanism of action. In addition to antiresorptive activity, clodronate has shown anti-inflammatory and analgesic properties, and modulatory effects on bone and cartilage metabolism. 849 0 obj <>stream 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. For more information, see: – Van Rooijen, N., & Sanders, A. NIH  |  HHS Miracle Mix … Clodronate is a medicine used to treat a high level of calcium in the blood caused by changes in the body that happen with cancer. About Clodronate Liposomes. Request PDF | Clodronate: Old Drug, New Uses | Clodronate (CLO) is a bisphosphonate (BP) with proved efficacy in the treatment of osteoporosis. Bone Res. 4 The first pyrophosphate-like bisphosphonates (such as etidronate and clodronate) are incorporated into adenosine triphosphate (ATP), a source of energy in the cell. Author information: (1)Department of Surgery, University of Oulu, Oulu, Finland. Front Immunol. The phagocyte immediately recognizes the liposomes as foreign particles and proceeds with destroying these invading particles. Alendronate or the native form of clodronate did not have any immediate effect on mitochondria. Clodronate, alendronate, and other bisphosphonates are widely used in the treatment of bone diseases characterized by excessive osteoclastic bone resorption. 8 Patients should be counselled regarding the risk of hypocalcemia, hypovolemia, renal insufficiency, transient hyperphosphatemia, … 2001 Sep;44(9):2201-10. doi: 10.1002/1529-0131(200109)44:9<2201::aid-art374>3.0.co;2-e. Frith JC, Mönkkönen J, Blackburn GM, Russell RG, Rogers MJ. Mechanisms of hepatic ischemia-reperfusion injury and protective effects of nitric oxide. Because a bisphosphonate group mimics the structure of pyrophosphate, it can inhibit activation of enzymes that utilize pyrophosphate. Surg. See BISPHOSPHONATES . Hearts in Healthcare . Clodronate (CLO) is a bisphosphonate (BP) with proved efficacy in the treatment of osteoporosis. 2011 Jul;49(1):2-19. doi: 10.1016/j.bone.2011.04.022. %PDF-1.5 %���� New insights into the molecular mechanisms of action of bisphosphonates.

After fusion with lysosomes (L) containing phospholipases (arrowheads), the latter disrupt the bilayers of the liposomes. Clodronate (CI2MBP) is a non-aminated bisphosphonate that inhibits bone resorption. Corresponding Author. 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. Medicinal forms. There can be variation in the licensing of different … Mönkkönen H, Auriola S, Lehenkari P, Kellinsalmi M, Hassinen IE, Vepsäläinen J, Mönkkönen J. Br J Pharmacol. Epub 2011 May 1. Fiani ML, Barreca V, Sargiacomo M, Ferrantelli F, Manfredi F, Federico M. Int J Mol Sci. The relationship between molecular action and antiresorptive effects has been documented for BPs lacking and containing nitrogen.
