Definitions

  • the present invention relates to a class of compounds having a PCSK9 inhibitor having a piperidine ring structure, and in particular to a compound of the formula (I) and a pharmaceutically acceptable salt thereof.
  • Plasma low-density lipoprotein cholesterol (LDL-C) levels are closely related to the risk of cardiovascular disease, and the low-density lipoprotein receptor (LDL-R) expressed on the surface of liver cells is the primary factor determining LDL-C levels.
  • PCSK9 in the blood can specifically bind to the LDL-R on the cell surface to form a complex and transport to the lysosome, which leads to accelerated degradation of LDL-R and elevated LDL-C levels.
  • a large number of basic research and clinical trial results show that exogenous interventions can inhibit the clearance of low-density lipoprotein (LDL) in plasma after inhibiting PCSK9 activity, resulting in good lipid-lowering effects. Therefore, PCSK9 inhibitors are likely to be a new generation of drugs for the treatment of dyslipidemia and related cardiovascular diseases.

Description

作为PCSK9抑制剂的哌啶类化合物 技术领域
本发明涉及一类具有哌啶环结构的PCSK9抑制剂的化合物,具体涉及式(I)所示化合物及其药学上可接受的盐。
背景技术
血浆低密度脂蛋白胆固醇(LDL-C)水平与心血管疾病的发生风险密切相关,肝脏细胞表面表达的低密度脂蛋白受体(LDL-R)是决定LDL-C水平的首要因素。血液中的PCSK9可以与细胞表面的LDL-R发生特异性结合形成复合物并转运至溶酶体,从而导致LDL-R加速降解,使LDL-C水平升高。大量的基础研究和临床试验结果表明,外源性干预措施抑制PCSK9活性后,可加速血浆中低密度脂蛋白(LDL)清除,从而产生良好的降脂效果。因此,PCSK9抑制剂很可能将是治疗血脂紊乱及相关心血管疾病的新一代药物。

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、有机氨或镁盐或类似的盐。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(参见Berge et al.,"Pharmaceutical Salts",Journal of Pharmaceutical Science 66:1-19(1977))。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。
优选地,以常规方式使盐与碱或酸接触,再分离母体化合物,由此再生化合物的中性形式。化合物的母体形式与其各种盐的形式的不同之处在于某些物理性质,例如在极性溶剂中的溶解度不同。
本文所用的“药学上可接受的盐”属于本发明化合物的衍生物,其中,通过与酸成盐或与碱成盐的方式修饰所述母体化合物。药学上可接受的盐的实例包括但不限于:碱基比如胺的无机酸或有机酸盐、酸根比如羧酸的碱金属或有机盐等等。药学上可接受的盐包括常规的无毒性的盐或母体化合物的季铵盐,例如无毒的无机酸或有机酸所形成的盐。常规的无毒性的盐包括但不限于那些衍生自无机酸和有机酸的盐,所述的无机酸或有机酸选自2-乙酰氧基苯甲酸、2-羟基乙磺酸、乙酸、抗坏血酸、苯磺酸、苯甲酸、氢碳酸、碳酸、柠檬酸、依地酸、乙烷二磺酸、乙烷磺酸、富马酸、葡庚糖酸、葡糖酸、谷氨酸、乙醇酸、氢溴酸、盐酸、氢碘酸、羟萘酸、羟乙磺酸、乳酸、乳糖酸、十二烷基磺酸、马来酸、苹果酸、扁桃酸、甲烷磺酸、硝酸、草酸、双羟萘酸、泛酸、苯乙酸、磷酸、多聚半乳糖醛酸、丙酸、水杨酸、硬脂酸、亚乙酸、琥珀酸、氨基磺酸、对氨基苯磺酸、硫酸、单宁酸、酒石酸和对甲苯磺酸。

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)。

术语“赋形剂”通常是指配制有效的药物组合物所需要载体、稀释剂和/或介质。
针对药物或药理学活性剂而言,术语“有效量”或“治疗有效量”是指无毒的但能达到预期效果的药物或药剂的足够用量。对于本发明中的口服剂型,组合物中一种活性物质的“有效量”是指与该组合物中另一种活性物质联用时 为了达到预期效果所需要的用量。有效量的确定因人而异,取决于受体的年龄和一般情况,也取决于具体的活性物质,个案中合适的有效量可以由本领域技术人员根据常规试验确定。
术语“活性成分”、“治疗剂”,“活性物质”或“活性剂”是指一种化学实体,它可以有效地治疗目标紊乱、疾病或病症。
“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。当取代基为酮基(即=O)时,意味着两个氢原子被取代。酮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。
当一个取代基可以连接到一个环上的一个以上原子时,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
