for the measurement of vitamin D and its metabolites using stable isotope-labeled internal standards and mass spectrometry are reviewed. The synthesis of both labeled and unlabeled standards is illustrated, and details of the synthesis of (26,26,27,27,27(-2)H5)-25,26-dihydroxyvitamin D3 and (28,28,28(-2)H3)-24,25-dihydroxyvitamin D2 are given. The use of in vitro biologic systems for the production of
综述了使用稳定同位素标记的内标和质谱法测量维生素 D 及其代谢物的方法。说明了标记和未标记标准的合成,以及合成 (26,26,27,27,27(-2)H5)-25,26-dihydroxyvitamin D3 和 (28,28,28(-2) )H3)-24,25-二羟基维生素D2。讨论了使用体外生物系统生产氘化 25-羟基维生素 D3 的进一步代谢物。在分离的灌注大鼠肾脏中使用氘化 25-羟基二氢速甾醇 3 作为底物为确定该系统中形成的 25-羟基二氢速甾醇 3 的许多代谢物的结构提供了有价值的数据。
