In an effort to develop novel vitamin D3 analogues, a series of aromatic compounds was synthetized, using efficient Negishi cross coupling between alkenylzinc reagents of the C,D-ring moiety of vitamin D3, and various substituted aromatic halides as A-ring mimics. The study aimed at exploring the influence of the replacement of the original vitamin D3 diene by a styrene unit on the biological activities
为了开发新型的维生素D3类似物,使用维生素D3的C,D环部分的烯基锌试剂与各种取代的芳香族卤化物(作为A环模拟物)之间的有效Negishi交叉偶联反应,合成了一系列芳香族化合物。该研究旨在探讨苯乙烯单元替代原始维生素D3二烯对生物活性的影响。铅化合物36诱导HL-60细胞分化的效力比骨化三醇低12倍,这与对VDR的结合亲和力较弱有关。
