Here, we aimed to design and synthesize non-steroidal DPM-type STS inhibitors that would also serve as pro-estrogen antagonists, releasing a metabolite with ERα-antagonistic activity upon hydrolysis by STS. We synthesized a series of compounds and evaluated their biological activities by means of STS-inhibitory activity assay and ER reporter gene assay. Among them, silicon-containing compound 16a showed
甾族硫酸酯酶(STS)是治疗绝经后激素依赖性乳腺癌的潜在靶标。已经报道了几种类固醇STS抑制剂,但是类固醇化合物难以优化并且可能与其他靶标相互作用。另一方面,我们已经证明二苯甲烷(DPM)衍生物充当雌激素受体(ER)激动剂和拮抗剂。在这里,我们旨在设计和合成非甾体DPM型STS抑制剂,它们也可以用作促雌激素拮抗剂,在被STS水解后释放具有ERα拮抗活性的代谢产物。我们合成了一系列化合物,并通过STS抑制活性测定和ER报告基因测定评估了它们的生物学活性。其中,含硅化合物16a表现出较强的STS抑制活性(IC50 = 0.17μM)。此外,其推定的代谢产物(12a)表现出有效的ERα拮抗活性(IC 50 = 29.7 nM)。
