agonistic activities. Especially, compound 19f displayed the most anti-proliferative activities against MCF-7 and PC-3 cells with the IC50 values of 1.80 and 5.35μM, respectively, which was comparable to positive control 1,25-(OH)2D3. Moreover, compound 19f exhibited reduced toxicity against human normal liver cell line (L02) compared with the parental compound 7. Besides, the preliminary structure-activity
1α,25-二羟基维生素D3(1,25-(OH)2D3,也称为骨化三醇),维生素D3的活性形式,在癌症治疗中得到越来越多的认可。我们以前的工作表明,苯基-吡咯基戊烷类似物可模拟对天然类固醇配体1,25-(OH)2D3的几种癌细胞系的抗增殖活性。在这里,为了优化结构特征并发现更有效的衍生物,设计,合成和评估了一系列带有乙炔键的非甾体维生素D3受体(VDR)配体。它们中的大多数显示出中等至良好的结合亲和力和激动活性。尤其是,化合物19f对MCF-7和PC-3细胞表现出最大的抗增殖活性,其IC50值分别为1.80和5.35μM,与阳性对照1,25-(OH)2D3相当。
