Several regioisomeric tetrazolyl indole derivatives with structurally modified alkyl substituents at the tetracyclic indole nitrogen containing N-ethyl amino tetrazole moiety have been synthesized and screened for their ER binding affinity, agonist (estrogenic), antagonist (antiestrogenic) and anti-implantation activities. N-2 regioisomers were found to be moderately antagonists and one compound showed
已经合成了几种在四环吲哚含氮的N-乙基氨基四唑部分具有结构修饰的烷基取代基的区域异构四唑基吲哚衍生物,并对其ER结合亲和力,激动剂(雌激素),拮抗剂(抗雌激素)和抗植入活性进行了筛选。发现N-2区域异构体是中度拮抗剂,一种化合物在10 mg / kg剂量下显示100%的避孕功效。与雌二醇和雷洛昔芬进行的分子对接研究表明两种区域异构体与结合位点的结合方式不同。
