cells lines (GI(50) of 340-850 nM) could be retained when the heterocyclic substituent possesses H-bond acceptor properties. A good correlation between the calculated electron density of the heterocyclic ring and anti-proliferative activity was observed. Docking of the most active compounds into their putative site of action, the colchicine binding site of tubulin, suggests that they bind through a
2-取代的estra-1,3,5(10)-三烯-3-O-氨基磺酸盐在体外和体内肿瘤细胞增殖方面的强大活性突出了此类化合物的治疗潜力。最佳活性来自2-XMe基团(其中X = CH(2),O或S),甾族A环中的3-O-氨基磺酸酯基团和C-17附近的H键受体的组合D环的 在这里,我们描述了一系列带有杂环取代基(恶唑,四唑,三唑)的新型2-取代的estra-1,3,5(10)-三烯-3-O-氨基磺酸盐的合成和抗增殖活性-17。这些分子的体外评估表明,当杂环取代基具有H键受体特性时,乳腺癌和前列腺癌细胞系中的高抗增殖活性(GI(50)为340-850 nM)可以保留。观察到杂环的电子密度与抗增殖活性之间具有良好的相关性。将活性最高的化合物对接至其假定的作用位点,即微管蛋白的秋水仙碱结合位点,表明它们以不同的方式与先前描述的双氨基磺酸酯衍生物1和2结合,后者具有相似的体外活性。
