    • Non ligand binding pocket antagonists for the human androgen receptor. The androgen receptor (AR) is a member of the Nuclear Receptor (NR) family and its role is to modulate the biological effects of the endogenous androgens, testosterone (tes) and dihydrotestosterone (DHT). Synthetic androgens and anti-androgens have therapeutic value in the treatment of various androgen dependent conditions, from regulation of male fertility to prostate cancer. Current treatment of prostate cancer (PCa) typically involves administration of ‘classical’ antiandrogens, competitive inhibitors of natural AR ligands, DHT and tes, for the ligand binding pocket (LBP) in the C-terminal ligand binding domain (LBD) of the AR. However, prolonged LBP-targeting can often lead to androgen resistance and alternative therapies and therapeutic strategies are urgently required. Disclosed herein are a class of non-steroidal, small molecule AR antagonists which inhibit the transcriptional activity of the AR by non LBP-mediated modulation. The novel class reported demonstrates full (‘true’) antagonism in AR with low micromolar potency, high selectivity over both the Estrogen Receptors alpha and beta (ERα and ERβ) and the Glucocorticoid Receptor (GR) and only micromolar partial antagonism in the Progesterone Receptor (PR). Data provide compelling evidence for such non-LBP intervention as an alternative approach to classical PCa therapy. (Formula I).
    • 用于人雄激素受体的非配体结合口袋拮抗剂。 雄激素受体(AR)是核受体(NR)家族的成员,其作用是调节内源雄激素,睾丸激素(tes)和二氢睾酮(DHT)的生物学作用。 合成雄激素和抗雄激素在治疗各种雄激素依赖性病症方面具有治疗价值,从调节男性生殖力到前列腺癌。 前列腺癌(PCa)的当前治疗通常涉及对AR的C-末端配体结合结构域(LBD)中的配体结合口袋(LBP)施用“经典”抗雄激素,天然AR配体的竞争性抑制剂,DHT和tes 。 然而,长期的LBP靶向通常可导致雄激素抵抗,迫切需要替代疗法和治疗策略。 本文公开了一类非甾体的小分子AR拮抗剂,其通过非LBP介导的调节来抑制AR的转录活性。 报道的新一代报道在AR中具有低的(“真实”)拮抗作用,具有低微摩尔效力,对雌激素受体α和β(ERα和ER和bgr)和糖皮质激素受体(GR)的高选择性,而孕激素中仅有微摩尔部分拮抗作用 受体(PR)。 数据为这种非LBP干预提供了令人信服的证据,作为经典PCa治疗的替代方法。 (式I)。
