indole-based analogs to be synthesized targeting the ligand binding domain of estrogen receptor-α. In vitro studies revealed the potential of the total sub-classes of the synthesized analogs to show anti-proliferative activity against estrogen receptor-dependent cancer cell lines at IC50 ranging from 28.23 to 57.13 μM. This was further validated by evaluating the potential of the synthesized analogs to compete
提供靶向雌激素受体的新型支架产生了巨大的必要性,以克服由肿瘤产生的不断发展的抗性。基于结构的药物设计与类固醇骨架的开环策略相结合,揭示了以雌激素受体-α的配体结合域为基础合成基于吲哚的类似物的潜力。体外研究表明,合成类似物的全部亚类可能在IC 50为28.23至57.13μM时显示出抗雌激素受体依赖性癌细胞系的抗增殖活性。通过评估合成的类似物通过ER-αELISA分析与雌二醇竞争以显示IC 50抑制谱的潜力进一步证实了这一点。范围从1.76到204.75 nM。两种类似物(YMA-005和YMA-006)在两种剂量水平下均显示出肿瘤大小的显着减少,并伴有广泛的变性和坏死。YMA-005和YMA-006均在两种剂量水平下均显示ER-α免疫组织化学表达的原位降低。最终,提供了基于吲哚的雌酮支架仿生的新型类似物作为雌激素受体-α抑制剂。
