An effective endocrine therapy for breast cancer is to selectively and effectively degrade the estrogen receptor (ER). Up until now, there have been largely only two molecular scaffolds capable of doing this. In this study, we have developed new classes of scaffolds that possess selective estrogen receptor degrader (SERD) and ER antagonistic properties. These novel SERDs potently inhibit MCF-7 breast
乳腺癌的有效内分泌治疗是选择性和有效降解雌激素受体(ER)。迄今为止,基本上只有两种分子支架能够做到这一点。在这项研究中,我们已经开发出具有选择性雌激素受体降解剂(SERD)和ER拮抗特性的新型支架。这些新颖的SERD可以有效抑制MCF-7乳腺癌细胞的增殖和ER靶基因的表达,其功效与Fulvestrant相当。与Fulvestrant不同的是,这些新型SERD的模块化蛋白靶向嵌合体(PROTAC)型设计应易于分散到类似物库中,以进一步微调其药代动力学特性,包括口服有效性。
