Steroid sulfatase inhibitors block the local production of estrogenic steroids and are attractive agents for the treatment of estrogen-dependent cancers. Inspiration of coumarin-based inhibitors, we synthesized thirty-two 5-oxa-1,2,3,4-tetrahydro-2H-chromeno-(3,4-c)pyridin-8-yl sulfamates, focusing on the substitution derivatives on the adjacent phenyl ring and evaluated their abilities to block STS
类固醇硫酸酯酶抑制剂阻断雌激素类固醇的局部产生,是治疗雌激素依赖性癌症的有吸引力的药物。受香豆素类抑制剂的启发,我们合成了 32 个5-oxa-1,2,3,4-tetrahydro-2H-chromeno-(3,4-c)pyridin-8-yl sulfamates,重点是取代衍生物相邻的苯环,并评估了它们阻断来自人胎盘和 MCF-7 细胞的 STS 的能力。SAR 分析表明,氯在间位和/或对位的掺入三环骨架的相邻苯环的位置增强了 STS 抑制。相邻苯环上的双取代优于单取代和三取代。对这些化合物的进一步动力学分析表明,含氯化合物(例如19 m、19v和19w)的K I为 0.02 至 0.11 nM,k inact / K I比率为 8.8–17.5 nM -1 min - 1,一个表示不可逆抑制效率的参数。我们还使用对接模型来说明化合物在 STS 抑制效力方面的差异。最后,还研究了所选化
