前列环素受体受体激动剂

技术领域
本发明涉及式(Ⅰ)所示化合物、其异构体或其药学上可接受的盐,并涉及其在制备治疗与PGI 2受体相关疾病药物中的应用。
背景技术
前列环素(Prostacyclin,PGI 2)是花生四烯酸(Arachidonic acid,AA)的代谢产物之一,主要由血管内皮细胞产生。在生物体内,花生四烯酸在环氧合酶的作用下转变成前列腺素G 2(prostaglandin G 2,PGG 2),后者在过氧化酶的作用下生成前列腺素H2(prostaglandin H 2,PGH 2),前列腺素H 2是重要的代谢中间体,通过它经由不同的途径可以得到一系列不同的前列腺素,在前列环素合成酶的作用下,前列腺素H 2转变为前列环素。前列环素的主要靶标是前列环素受体(IP receptor),前列环素受体激活后与调节蛋白偶联并激活腺苷酸环化酶(Adenylate cyclase,AC),进而使靶细胞环磷酸腺苷(cAMP)含量升高,并同时发挥血管舒张、抗血小板聚集、抗增生和免疫调节等作用。
肺动脉高压(pulmonary arterialhypertension,PAH)是指海平面静息状态下,右导管检测肺动脉平均压力≥25mmHg的一组临床病理生理综合症,以肺小动脉的血管痉挛、内膜增生、重构为主要特征,导致肺血管阻力持续升高,最终会导致患者右心衰竭和死亡。肺动脉高压患者体内前列环素合成减少,因此,使用前列环素及其类似物,是一种可行的替代疗法。传统的前列环素及其类似物主要包括依前列醇(epoprostanol)、伊洛前列素(iloprost)、贝前列素(beraprost)和曲前列环素(treprostinil),它们共同的缺点是价格昂贵,代谢稳定性差,半衰期短,多通过注射给药。目前,许多专家认为静脉内给药的前列环素为治疗最严重的肺动脉高压患者的最可靠的药物,但由于前列环素半衰期短,如果输注突然中断,患者可能面临可能致命的反跳性肺高血压的危险。
为了克服这些缺点,近些年来一批新的、非前列腺素类、口服且长效的前列环素受体激动剂被研究开发出来,其中Selexipag是第一个获得FDA批准上市的此类化合物,该化合物最早由日本新药株式会社(Nippon Shinyaku)开发,2008年4月与瑞士爱可泰隆(Actelion)公司签订特许协议,该药于2015年底上市,商品名Uptravi,与之相关专利主要有WO2002088084、WO2009157398、WO2010150865和WO2011024874等。Ralinepag是另一个重要的非前列腺素类前列环素受体激动剂,该化合物由Arena公司开发,目前处于临床二期,相关的专利主要有WO2009117095和WO2011037613。

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“药学上可接受的盐”是指本发明化合物的盐,由本发明发现的具有特定取代基的化合物与相对无毒的酸或碱制备。当本发明的化合物中含有相对酸性的功能团时,可以通过在纯的溶液或合适的惰性溶剂中用足够量的碱与这类化合物的中性形式接触的方式获得碱加成盐。药学上可接受的碱加成盐包括钠、钾、钙、铵、有机胺或镁盐或类似的盐。当本发明的化合物中含有相对碱性的官能团时,可以通过在纯的溶液或合适的惰性溶剂中用足够量的酸与这类化合物的中性形式接触的方式获得酸加成盐。药学上可接受的酸加成盐的实例包括无机酸盐,所述无机酸包括例如盐酸、氢溴酸、硝酸、碳酸,碳酸氢根,磷酸、磷酸一氢根、磷酸二氢根、硫酸、硫酸氢根、氢碘酸、亚磷酸等;以及有机酸盐,所述有机酸包括如乙酸、丙酸、异丁酸、马来酸、丙二酸、苯甲酸、琥珀酸、辛二酸、反丁烯二酸、乳酸、扁桃酸、邻苯二甲酸、苯磺酸、对甲苯磺酸、柠檬酸、酒石酸和甲磺酸等类似的酸;还包括氨基酸(如精氨酸等)的盐,以及如葡糖醛酸等有机酸的盐。本发明的某些特定的化合物含有碱性和酸性的官能团,从而可以被转换成任一碱或酸加成盐。
本发明的药学上可接受的盐可由含有酸根或碱基的母体化合物通过常规化学方法合成。一般情况下,这样的盐的制备方法是:在水或有机溶剂或两者的混合物中,经由游离酸或碱形式的这些化合物与化学计量的适当的碱或酸反应来制备。
本发明的化合物可以存在特定的几何或立体异构体形式。本发明设想所有的这类化合物,包括顺式和反式异构体、(-)-和(+)-对对映体、(R)-和(S)-对映体、非对映异构体、(D)-异构体、(L)-异构体,及其外消旋混合物和其他混合物,例如对映异构体或非对映体富集的混合物,所有这些混合物都属于本发 明的范围之内。烷基等取代基中可存在另外的不对称碳原子。所有这些异构体以及它们的混合物,均包括在本发明的范围之内。
除非另有说明,术语“对映异构体”或者“旋光异构体”是指互为镜像关系的立体异构体。
除非另有说明,术语“顺反异构体”或者“几何异构体”系由因双键或者成环碳原子单键不能自由旋转而引起。
除非另有说明,术语“非对映异构体”是指分子具有两个或多个手性中心,并且分子间为非镜像的关系的立体异构体。
除非另有说明,“(+)”表示右旋,“(-)”表示左旋,“(±)”表示外消旋。

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。
除非另有说明,术语“富含一种异构体”、“异构体富集”、“富含一种对映体”或者“对映体富集”指其中一种异构体或对映体的含量小于100%,并且,该异构体或对映体的含量大于等于60%,或者大于等于70%,或者大于等于80%,或者大于等于90%,或者大于等于95%,或者大于等于96%,或者大于等于97%,或者大于等于98%,或者大于等于99%,或者大于等于99.5%,或者大于等于99.6%,或者大于等于99.7%,或者大于等于99.8%,或者大于等于99.9%。
除非另有说明,术语“异构体过量”或“对映体过量”指两种异构体或两种对映体相对百分数之间的差值。例如,其中一种异构体或对映体的含量为90%,另一种异构体或对映体的含量为10%,则异构体或对映体过量(ee值)为80%。
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)。本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。
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 PCTCN2019074575-appb-000049
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 PCTCN2019074575-appb-000050
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 PCTCN2019074575-appb-000051
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,术语“杂”表示杂原子或杂原子团(即含有杂原子的原子团),包括碳(C)和氢(H) 以外的原子以及含有这些杂原子的原子团,例如包括氧(O)、氮(N)、硫(S)、硅(Si)、锗(Ge)、铝(Al)、硼(B)、-O-、-S-、、-C(=O)O-、-C(=O)-、-C(=S)-、-S(=O)、-S(=O) 2-,以及任选被取代的-C(=O)N(H)-、-N(H)-、-C(=NH)-、-S(=O) 2N(H)-或-S(=O)N(H)-。

2.4监测指标
1).每天监测动物的一般状态及体重;
2).观察右心室收缩压(RVSP);
3).测定右室肥大指数(RVHI):右室重量/(左室重量+室间隔重量);
2.5实验方法
2.5.1右心导管法测量大鼠RVSP
2.5%戊巴比妥钠(2ml/kg,ip)麻醉大鼠,仰位固定动物于手术板上,去掉颈部皮毛,切开颈部皮肤,钝性分离皮下组织及肌层,剥离左颈动脉及右颈静脉。将与压力换能器相连接并充满0.3%肝素钠溶液的大鼠专用右心导管(PE管,外径约1.5mm,前端为小弧形)插入右颈外静脉。操作中保持肺动脉导管的弧向下方,并将肺动脉导管向右心房方向延伸,根据压力波形判断是否到达心脏部位,将插管左旋并向前推进进入右心室。
2.5.2 RVHI的测定
取出心脏,去除心房及大血管,用滤纸吸干水分,剥离右心室,并称重,计算RVHI=RV/(LV+SEP)。
RVHI:右心室肥大指数
RV:右心室重量
LV+SEP:左心室加室间隔重量
3.实验结果和结论
结果见图1和图2。
实验结论:本发明化合物对右心室平均收缩压(mRVSP)明显缓解,右心室肥大指数(RVHI)也明显缓解,并且有良好的剂量相关性,所以可以说明本发明化合物对疾病肺动脉高压在大鼠身上有明显的疗效。
