  • Synthesis and biological activity of (22E,24R)- and (22E,24S)-1.ALPHA.,24-dihydroxy-22-dehydrovitamin D3.

    Chemical synthesis of (22E, 24R)- and (22E, 24S)-1, 24-dihydroxy-Δ22-vitamin D3 has been achieved starting with the commercially available dinorcholenic acid acetate. Synthesis involved introduction of the 1-hydroxy group by a reduction of the 1, 2-epoxide generated by epoxidation of the 1, 4, 6-trien-3-one. The side chain on the steroid was then constructed by means of a Wittig reaction followed by introduction of the Δ7 bond by standard methods and its protection with 1-phenyl-1, 2, 4-triazoline-3, 5-dione. Subsequent reduction of the hydroxy groups in the steroid side chain followed by reduction of the Diels-Alder addition products yielded the both 24-isomers. The 5, 7-dienes were irradiated and the corresponding vitamin D compounds isolated. Nuclear magnetic resonance was used to identify individual isomers. The (22E, 24S)-1, 24-hydroxyvitamin D3 compound bound equally well to the chick intestinal cytosol receptor as 1, 25-dihydroxyvitamin D3, while the 24R-isomer was approximately ten times less active. In vivo, both isomers were less active than 1, 25-dihydroxyvitamin D3 ; however, the 24S-isomer was considerably more active than the 24R-isomer approaching the activity of 1, 25-dihydroxyvitamin D3.
    (22E, 24R)- 和 (22E, 24S)-1,24-二羟基-Δ22-维生素 D3 的化学合成是从市售的二去甲胆烯酸乙酸酯开始的。合成过程包括通过还原 1,4,6-三烯-3-酮环氧化反应生成的 1,2-环氧化物来引入 1-羟基。然后通过维蒂希反应构建类固醇的侧链,再通过标准方法引入 Δ7 键,并用 1-苯基-1,2,4-三唑啉-3,5-二酮对其进行保护。随后还原类固醇侧链中的羟基,再还原 Diels-Alder 加成产物,就得到了 24-异构体。对 5,7-二烯进行辐照,分离出相应的维生素 D 化合物。核磁共振被用来鉴定单个异构体。(22E, 24S)-1,24-羟维生素 D3 复合物与 1,25-二羟基维生素 D3 一样能很好地与小鸡肠道细胞质受体结合,而 24R 异构体的活性大约低十倍。在体内,两种异构体的活性都低于 1, 25-二羟基维生素 D3;但是,24S-异构体的活性大大高于 24R-异构体,接近 1, 25-二羟基维生素 D3 的活性。
