Selective Estrogen Receptor Modulators (SERMs) are characteristically capable of being
antagonist and agonist of estrogen receptors and, therefore, they can inhibit or stimulate estrogen production
in different tissues. Aiming to contribute to the identification of new synthetic SERMs candidates, the basic skeletons
of raloxifene and tamoxifene were used as model. Here of, a set of 2,3-diaryl-quinoxalines having 2-(piperidin-1-
yl)ethanol in the side chain have been synthesized and evaluated against human mammary carcinoma cells estrogen dependent
(MCF-7), as well as in recombinant yeast assays (RYA) expressing estrogen receptor. Compound LSPN332
showed 40% inhibition of MCF-7 and EC50=290.6 µM in RYA. The efficient synthesis of 2,3-diarylquinoxalines represents
an excellent opportunity to identify new SERMs, and should therefore be of interest to the medicinal chemistry
community.
选择性雌激素受体调节剂(SERMs)特征上能够作为雌激素受体的拮抗剂和激动剂,因此,它们可以在不同的组织中抑制或刺激雌激素的产生。为了帮助识别新的合成SERMs候选物,以来氟烯和他莫昔芬的基本骨架作为模型。在此基础上,合成了一组含有2-(哌啶-1-基)乙醇侧链的2,3-二芳基喹喧烯,并对其在雌激素依赖的人乳腺癌细胞(MCF-7)以及表达雌激素受体的重组酵母实验(RYA)中进行评估。化合物LSPN332在MCF-7中显示出40%的抑制率,在RYA中的EC50为290.6 µM。2,3-二芳基喹喧烯的高效合成为识别新的SERMs提供了极好的机会,因此应该引起药物化学界的关注。
