技术领域
本发明涉及药物领域,具体涉及一类作为RHO激酶抑制剂的吡唑类化合物,其药学上可接受的盐或其异构体,其药物组合物以及它们在制备RHO抑制剂药物中的应用。
背景技术
RHO相关蛋白激酶(Rho associated kinase,简称ROCK),属于丝氨酸/苏氨酸蛋白激酶,是RHO的下游靶效应分子,在人体内广泛表达。RHO相关蛋白激酶(ROCK)参与肌球蛋白轻链(MLC)的调节,适用于血管舒张的治疗,新的研究支持ROCK激酶参与TH17细胞的免疫反应的调控和纤维母细胞的活化,可以扩展适应症用于肺纤维化,哮喘等肺部疾病,进一步的适应症拓展包括自身免疫疾病。ROCK激酶家族包括ROCK1和ROCK2两个亚型,ROCK2激酶和炎症作用和纤维化作用相关,选择性ROCK2抑制剂在离体血管舒张实验中在高浓度也没有引起血管舒张,可以减少心血管副作用。ROCK1敲除小鼠虽然胚胎死亡率不高,但是出生后大部分死于MLC磷酸化降低造成的细胞骨架变异,而ROCK2敲除小鼠90%在胚胎期死亡,但是存活的小鼠和野生型没有区别,选择性抑制ROCK2的活性可能具有更高的安全性。因此,选择性ROCK2蛋白激酶抑制剂可以避免药物的心血管副作用。
KD025(WO2006105081;WO2008054599;WO2010104851;WO2014055996)是Kadmon公司开发的口服ROCK2激酶选择性的抑制剂。研究表明,KD025是通过抑制RHO激酶这类调节纤维化的蛋白来治疗特发性肺纤维化(IPF)这种新机制的代表。特发性肺纤维化(IPF)的诱因可能是肌体损伤。肌体对损伤的应答涉及多种细胞(比如上皮细胞、成纤维细胞、内皮细胞和巨噬细胞等)的肌动蛋白细胞骨架的重组,而肌动蛋白丝(actin filament)的组装和肌动球蛋白(actomyosin)的收缩则由RHO激酶家族蛋白质(包括ROCK1和ROCK2)指导调控。之前的研究显示,RHO激酶家族蛋白会在IPF患者以及这种疾病的动物模型肺部激活,而RHO激酶抑制剂可以预防这些模型中的组织纤维化过程,并且能诱导已经建立的纤维化出现消退。目前已完成中度至重度银屑病治疗的II期临床试验,并处于特发性肺纤维化(IPF)治疗的II期临床研究阶段。

本发明的化合物可以存在特定的。除非另有说明,术语“互变异构体”或“互变异构体形式”是指在室温下,不同官能团异构体处于动态平衡,并能很快的相互转化。若互变异构体是可能的(如在溶液中),则可以达到互变异构体的化学平衡。例如,质子互变异构体(proton tautomer)(也称质子转移互变异构体(prototropic tautomer))包括通过质子迁移来进行的互相转化,如酮-烯醇异构化和亚胺-烯胺异构化。价键异 构体(valence tautomer)包括一些成键电子的重组来进行的相互转化。其中酮-烯醇互变异构化的具体实例是戊烷-2,4-二酮与4-羟基戊-3-烯-2-酮两个互变异构体之间的互变。

可以通过的手性合成或手性试剂或者其他常规技术制备光学活性的(R)-和(S)-异构体以及D和L异构体。如果想得到本发明某化合物的一种对映体,可以通过不对称合成或者具有手性助剂的衍生作用来制备,其中将所得非对映体混合物分离,并且辅助基团裂开以提供纯的所需对映异构体。或者,当分子中含有碱性官能团(如氨基)或酸性官能团(如羧基)时,与适当的光学活性的酸或碱形成非对映异构体的盐,然后通过本领域所公知的常规方法进行非对映异构体拆分,然后回收得到纯的对映体。此外,对映异构体和非对映异构体的分离通常是通过使用色谱法完成的,所述色谱法采用手性固定相,并任选地与化学衍生法相结合(例如由胺生成氨基甲酸盐)。
发明的化合物可以在一个或多个构成该化合物的原子上包含非天然比例的原子同位素。例如,可用放射性同位素标记化合物,比如氚( 3H),碘-125( 125I)或C-14( 14C)。又例如,可用重氢取代氢形成氘代药物,氘与碳构成的键比普通氢与碳构成的键更坚固,相比于未氘化药物,氘代药物有降低毒副作用、增加药物稳定性、增强疗效、延长药物生物半衰期等优势。本发明的化合物的所有同位素组成的变换,无论放射性与否,都包括在本发明的范围之内。
“任选”或“任选地”指的是随后描述的事件或状况可能但不是必需出现的,并且该描述包括其中所述事件或状况发生的情况以及所述事件或状况不发生的情况。
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。
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 PCTCN2019083208-appb-000071
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
Figure PCTCN2019083208-appb-000072
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 PCTCN2019083208-appb-000073
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。所述位点与其他基团连接的化学键可以用直形实线键
