A process for producing hydroxyvitamin D derivatives, characterized by converting a hydrogen atom or atoms at the 2-position, 24-position, 25-position and/or 26-position of a vitamin D into a hydroxyl group or groups in a solution containing a microorganism that belongs to the genus Nocardia, Streptomyces, Sphingomonas or Amycolata which has an ability to hydroxylate vitamin Ds or an enzyme produced by that microorganism, and optionally under the coexistence of a cyclodextrin; and novel vitamin D3 derivatives obtained by that process.
一种生产羟基维生素 D 衍生物的工艺,其特征在于:在含有具有羟基化维生素 D 的能力的诺卡氏菌属、链霉菌属、 鞘氨单胞菌属或艾美科拉菌属微生物或由该微生物产生的酶的溶液中,将维生素 D 的 2 位、24 位、25 位和/或 26 位上的一个或多个氢原子转化为一个或多个羟基,并可选择与环糊精共存;以及通过该工艺获得的新型维生素 D3 衍生物。
