cotransfection assays with human androgen receptor (hAR). This series of AR antagonists is structurally characterized by a linear tricyclic 1,2-dihydropyridono[5,6-g]quinoline core. Analogues inhibit AR-mediated reporter gene expression and bind to AR as potently as or better than any known AR antagonists. Several analogues also showed excellent in vivo activity in classic rodent models of AR antagonism, inhibiting
使用与人类雄激素受体(hAR)的基于细胞的共转染测定法,已经发现了一种新的非甾体抗雄激素药效团。这一系列AR拮抗剂的结构特征是线性三环1,2-二氢吡啶并[5,6-g]喹啉核心。类似物与任何已知的AR拮抗剂一样有效地抑制或抑制了AR,从而抑制了AR介导的报道基因的表达并与AR结合。几种类似物在经典的AR拮抗啮齿动物模型中也显示出出色的体内活性,抑制了大鼠腹侧前列腺和精囊的生长,没有伴随其他促性腺激素拮抗剂所引起的血清促性腺激素和睾丸激素水平的增加。研究该药效团周围的构效关系后,发现分子对AR具有完全的特异性,在前列腺癌患者中通常观察到的对AR突变体具有拮抗活性,并提高了体内功效。基于这一系列化合物的分子有潜力为治疗前列腺癌和其他雄激素依赖性疾病提供独特而有效的临床机会。
