The synthesis of novel triarylethylene analogs, designed based on well-known Selective Estrogen Receptor Modulators (SERMs), i.e., ospemifene and tamoxifen, as potential anti-breast cancer agents is described. The cytotoxic potential of these analogs against ER-positive (MCF-7) and ER-negative (MDA-MB-231) human breast cancer cell lines was determined and compared with the standards, ospemifene and
描述了基于众所周知的选择性雌激素受体调节剂(SERM)(即奥司哌米芬和他莫昔芬)设计的新型三芳基乙烯类似物的合成,作为潜在的抗乳腺癌药物。确定了这些类似物对ER阳性(MCF-7)和ER阴性(MDA-MB-231)人乳腺癌细胞系的细胞毒性潜力,并将其与标准品奥司哌米芬和他莫昔芬进行了比较。在最初的筛选,类似物5,14和15被认为是比对两种细胞系的标准有效得多。结果表明,这些新颖的类似物抑制了参与迁移和转移的蛋白质的表达,化合物5是最有效的。化合物5抑制MCF-7和MDA-MB-231细胞中MMP-9,c-Myc和Caveolin的表达,并以剂量依赖性方式抑制ER阴性细胞的侵袭。最后,代表性化合物在雌激素受体(ER)结合位点的计算机对接模拟表明这些化合物与ER具有良好的结合亲和力,并支持了它们对MCF-7癌细胞系的实验毒性。
