Structure:
DrugBank Description: Alendronic acid is a second generation bisphosphonate that is used for the treatment of some forms of osteoperosis and Paget's disease. It functions by preventing resorption of bone.
CAS Number: 66376-36-1
Molecular Weight: 249.096
DrugBank Indication: Alendronic acid is indicated for the treatment and prevention of osteoporosis in men and postmenopausal women, treatment of glucocorticoid-induced osteoporosis, and Paget's disease of bone. However, alendronic acid is not indicated for use in pediatric populations or patients with a creatinine clearance <35mL/min.
DrugBank Pharmacology: Alendronic acid tablets have a very low oral bioavialability. After administration it distributes into soft tissue and bone or is excreted in the urine. Alendronic acid does not undergo metabolism.
DrugBank MoA: Alendronic acid binds to bone hydroxyapatite. Bone resorption causes local acidification, releasing alendronic acid which is that taken into osteoclasts by fluid-phase endocytosis. Endocytic vesicles are acidified, releasing alendronic acid to the cytosol of osteoclasts where they induce apoptosis. Inhibition of osteoclasts results in decreased bone resorption which is shown through decreased urinary calcium, deoxypyridinoline and cross-linked N-telopeptidases of type I collagen.
Targets: Farnesyl pyrophosphate synthase inhibitor; Hydroxylapatite antagonist; Tyrosine-protein phosphatase non-receptor type 4 inhibitor; Receptor-type tyrosine-protein phosphatase S inhibitor; Receptor-type tyrosine-protein phosphatase epsilon inhibitor; V-type proton ATPase catalytic subunit A inhibitor
Inclusion Criteria: Therapeutic strategy associated
