一般描述

1α-Hydroxyvitamin D3, also known as alfacalcidol, is a synthetic vitamin D3 analogue, hydroxylated in position one. It is metabolized to 1,25-dihydroxycholecalciferol by 25-hydroxylases.

生化/生理作用

1α-Hydroxyvitamin D3 facilitates calcium absorption and deposition. It also has an ability to inhibit bone resorption and stimulate bone formation. Alfacalcidol is used for treating various bone diseases such as rickets/osteomalacia, renal osteodystrophy and osteoporosis. It acts as a chemopreventive agent and reduces the risk colitis and carcinogenesis.
Synthetic vitamin D3 analog that is metabolized to 1,25-dihydroxycholecalciferol. Inhibits bone resorption and stimulates bone formation. Supresses parathyroid hormone secretion by bovine parathyroid cells.
