A three series of thioureas, monothiourea type I (4a–g), 1,4-bisthiourea type II (5a–h) and 1,3-bisthiourea type III (6a–h) were synthesized. Their aromatase inhibitory activities have been evaluated. Interestingly, eight thiourea derivatives (4e, 5f–h, 6d, 6f–h) exhibited the aromatase inhibitory activities with IC50 range of 0.6–10.2 μM. The meta-bisthiourea bearing 4-NO2 group (6f) and 3,5-diCF3
合成了三个系列的硫脲:I型单硫脲(4a – g),II型1,4-双硫脲(5a – h)和III型1,3-双硫脲(6a – h)。已经评估了它们的芳香酶抑制活性。有趣的是,八种硫脲衍生物(4e,5f–h,6d,6f–h)表现出芳香化酶抑制活性,IC 50范围为0.6–10.2μM。所述元-bisthiourea轴承4-NO 2基(6F)和3,5- DICF 3组(6H)被证明是最有效的化合物,亚微摩尔IC 50值分别为0.8和0.6μM。分子对接还揭示了这两种化合物的硫脲部分之一可以通过与6f的Val370,Leu477,Thr310和Phe221酶残基,Val370,Leu477,Ser478和Ile133 6h)。这是首次报道双硫脲被开发为芳香酶抑制剂的潜力,其中4-NO 2和3,5-diCF 3类似物已被强调为有前途的候选物。
