A total synthetic strategy of 20S-hydroxyvitamin D3 [20S-(OH)D3] involving modified synthesis of key intermediates 7 and 12, Grignard reaction to stereoselectively generate 20S-OH and Wittig-Horner coupling to establish D3 framework, was completed in 16 steps with an overall yield of 0.4%. The synthetic 20S-(OH)D3 activated vitamin D receptor (VDR) and initiated the expression of downstream genes. In addition, 20S-(OH)D3 showed similar inhibitory potency as calcitriol [1,25(OH)2D3] on proliferation of melanoma cells.
一种20S-羟基维生素D3 [20S-(OH)D3]的全合成策略,涉及关键中间体7和12的改进合成、立体选择性生成20S-OH的格氏反应以及构建D3骨架的维蒂希-霍纳尔偶联反应,该策略以16步完成,总产率为0.4%。合成的20S-(OH)D3激活了维生素D受体(VDR)并启动了下游基因的表达。此外,20S-(OH)D3在抑制黑色素瘤细胞增殖方面表现出与骨化三醇[1,25(OH)2D3]相似的效力。
