Description

用作选择性雄激素受体调节剂的化合物
本申请主张如下优先权
CN201911142843.4;申请日:2019-11-20。
技术领域
本发明涉及一类作为非甾体类-选择性雄激素受体调节剂的化合物,及其在制备治疗雄激素受体介导的相关疾病的药物中的应用。具体涉及式(I)所示化合物或其药学上可接受的盐。
背景技术
雄激素受体(androgen receptor,AR)又称NR3C4,属于核受体超家族中的类固醇受体,通过与雄激素结合,可以刺激蛋白合成代谢,增强肌肉和骨骼,保持体内激素平衡等,是雄激素发挥重要生理作用的中介物质。随着年龄增大,人体内雄激素产量递减,年龄相关性疾病随之发生,例如肌肉萎缩、恶病质、骨质疏松症、骨折、疲劳虚弱、性腺功能低下及其他肌肉和骨骼病症,相应的雄激素疗法虽然可以通过激活雄激素受体来调控肌肉和骨骼的增长,缓解一系列雄激素缺乏症,但容易引起不良副作用,例如痤疮、女性男性化、面部和体毛过多、前列腺增生肥大、心血管相关疾病等。非甾体类-选择性雄激素受体调节剂(SARMs)作为雄激素受体的部分激动剂,可选择性刺激肌肉和骨骼中雄激素受体的合成代谢途径,增加肌纤维数量和厚度,增强骨密度和骨强度,加速骨折恢复,从而有效治疗肌肉萎缩、骨折等多种老年相关性疾病,而且避免了严重的副作用,治疗指数高。由Viking Therapeutics公司开发的非甾体类-选择性雄激素受体调节剂VK5211(WO2009082437)正在临床二期阶段。
鉴于选择性雄激素受体调节剂的重要作用,开发适用作治疗药物的选择性雄激素受体调节剂显得尤为重要。

定义和说明
除非另有说明,本文所用的下列术语和短语旨在具有下列含义。一个特定的术语或短语在没有特别定义的情况下不应该被认为是不确定的或不清楚的,而应该按照普通的含义去理解。当本文中出现商品名时,意在指代其对应的商品或其活性成分。
这里所采用的术语“药学上可接受的”,是针对那些化合物、材料、组合物和/或剂型而言,它们在可靠的医学判断的范围之内,适用于与人类和动物的组织接触使用,而没有过多的毒性、刺激性、过敏性反应或其它问题或并发症,与合理的利益/风险比相称。

术语“被取代的”是指特定原子上的任意一个或多个氢原子被取代基取代,可以包括重氢和氢的变体,只要特定原子的价态是正常的并且取代后的化合物是稳定的。当取代基为氧(即=O)时,意味着两个氢原子被取代。氧取代不会发生在芳香基上。术语“任选被取代的”是指可以被取代,也可以不被取代,除非另有规定,取代基的种类和数目在化学上可以实现的基础上可以是任意的。
当任何变量(例如R)在化合物的组成或结构中出现一次以上时,其在每一种情况下的定义都是独立的。因此,例如,如果一个基团被0-2个R所取代,则所述基团可以任选地至多被两个R所取代,并且每种情况下的R都有独立的选项。此外,取代基和/或其变体的组合只有在这样的组合会产生稳定的化合物的情况下才是被允许的。
当一个连接基团的数量为0时,比如-(CRR) 0-,表示该连接基团为单键。
当一个取代基数量为0时,表示该取代基是不存在的,比如-A-(R) 0表示该结构实际上是-A。
当一个取代基为空缺时,表示该取代基是不存在的,比如A-X中X为空缺时表示该结构实际上是A。
当其中一个变量选自单键时,表示其连接的两个基团直接相连,比如A-L-Z中L代表单键时表示该结构实际上是A-Z。
当一个取代基的键可以交叉连接到一个环上的两一个以上原子时,这种取代基可以与这个环上的任意原子相键合,例如,结构单元
Figure PCTCN2020130314-appb-000032
表示其取代基R可在环己基或者环己二烯上的任意一个位置发生取代。当所列举的取代基中没有指明其通过哪一个原子连接到被取代的基团上时,这种取代基可以通过其任何原子相键合,例如,吡啶基作为取代基可以通过吡啶环上任意一个碳原子连接到被取代的基团上。
当所列举的连接基团没有指明其连接方向,其连接方向是任意的,例如,
Figure PCTCN2020130314-appb-000033
中连接基团L为-M-W-,此时-M-W-既可以按与从左往右的读取顺序相同的方向连接环A和环B构成

也可以按照与从左往右的读取顺序相反的方向连接环A和环B构成
Figure PCTCN2020130314-appb-000035
所述连接基团、取代基和/或其变体的组合只有在这样的组合会产生稳定的化合物的情况下才是被允许的。
除非另有规定,当某一基团具有一个或多个可连接位点时,该基团的任意一个或多个位点可以通过化学键与其他基团相连。当该化学键的连接方式是不定位的,且可连接位点存在H原子时,则连接化学键时,该位点的H原子的个数会随所连接化学键的个数而对应减少变成相应价数的基团。所述位点与其他基团连接的化学键可以用直形实线键
