compounds was evaluated by the inhibition of their effect by ICI 182,780, an antiestrogenic compound. Among the compounds tested, 6,12-dihydro-3-methoxy-1-benzopyrano[3,4-b][1,4]benzothiazin-6-one 3e and 6,12-dihydro-3-hydroxy-1-benzopyrano[3,4-b][1,4]benzothiazin-6-one 3f exhibited an ER-dependent proliferation and a high binding affinity to ER, but a moderate capacity to activate the transcription of a reporter
在寻找由雌激素受体(ER)介导的具有雌激素活性的新药物中,合成了六个6,12-二氢-1-苯并吡喃并[3,4-b] [1,4]苯并噻嗪-6-酮3a-f。通过将2-氨基硫酚2加到取代的4-羟基香豆素衍生物1a-e中,可以容易地制备这些化合物。已评估了对MCF-7乳腺癌细胞增殖的雌激素作用,并通过ICI 182,780(一种抗雌激素化合物)抑制了其作用,从而评估了所描述化合物的特异性。在测试的化合物中,6,12-二氢-3-甲氧基-1-苯并吡喃并[3,4-b] [1,4]苯并噻嗪-6-one 3e和6,12-二氢-3-羟基-1-苯并吡喃[3,4-b] [1,4]苯并噻嗪-6-one 3f表现出ER依赖性增殖和对ER的高结合亲和力,但具有中等能力激活报告基因的转录。
