产品描述 | 25,26-Dihydroxyvitamin D3 (25,26-Dihydroxycholecalciferol) is a vitamin D3 metabolite and a precursor compound for the synthesis of 25-hydroxyvitamin D. |
体外活性 | 24,25 and 25,26 diOHD3 (0.125-0.250 mug) were able to increase calcium absorption in rats maintained on a calcium-deficient diet, but failed to do it in rats on a normal calcium diet. Bilateral nephrectomy suppressed this effect. The 'bone calcium mobilization' of both derivatives was measured in vitamin D and calcium- or phosphorus-deprived rats after one intravenous dose. When serum calcium was initially low, 24,25 and 25,26 diOHD3 increased serum calcium moderately, but the increment was only significant with 24,25 diOHD3 [2]. |
体内活性 | 24,25 和 25,26-Dihydroxyvitamin D3(0.125-0.250 mug)能够增加缺钙饮食大鼠对钙的吸收,但对正常钙饮食大鼠则无效。双侧肾切除术抑制了这种效果。两种衍生物的 “骨钙动员 ”是在维生素 D 和钙或磷缺乏的大鼠静脉注射一剂后测量的。当血清钙最初较低时,24,25 和 25,26-Dihydroxyvitamin D3 可适度增加血清钙,但只有 24,25 Dihydroxyvitamin D3 的增加幅度显著。[2] |
