Substituted phenylazo and phenylazoxy compounds were systematically prepared and their anti-androgenic activity was measured in terms of (1) the growth-inhibiting effect on an androgen-dependent cell line, SC-3, and (2) the binding affinity of nuclear androgen receptor. Generally, azo/azoxy compounds showed cell toxicity, and the growth-inhibiting effects on SC-3 cells correlated with the toxicity. However, some compounds, including 4, 4'-dinitroazobenzene (25), 4, 4'-dimethoxyazobenzene (33), and 2, 2'-dichloroazoxybenzene (47), possessed potent anti-androgenic activity without apparent cell toxicity.
苯基偶氮和苯基偶氮
肟化合物被系统地制备出来,并通过以下两种方式测定了它们的抗雄激素活性:(1)对依赖雄激素的
细胞系SC-3的生长抑制作用,以及(2)与核雄激素受体的结合亲和力。一般来说,偶氮/偶氮
肟化合物显示出细胞毒性,它们对SC-3细胞的生长抑制效应与毒性相关。然而,包括4,4'-二硝基
偶氮苯(25)、4,4'-二甲氧基
偶氮苯(33)和2,2'-二
氯偶氮
肟苯(47)在内的一些化合物,具有强大的抗雄激素活性而没有明显的细胞毒性。
