Definitions

  • the present invention relates to a compound represented by formula (I), its optical isomers and pharmacologically acceptable salts, and the application of the compound as an FXIa inhibitor.
  • Thromboembolic disease is a disease caused by abnormal blood clots formed in blood vessels during the survival of humans and animals. There are three reasons for thrombosis: blood vessel damage, blood changes and blood flow stasis; it is a group of complications caused by many different diseases and different reasons. Due to the differences in various underlying diseases and the location of thromboembolism, the clinical manifestations of thrombosis may include myocardial infarction, stroke, deep vein thrombosis (DVT), pulmonary embolism, atrial fibrillation and cerebral infarction, etc.
  • VVT deep vein thrombosis
  • Myocardial infarction, cerebral infarction, and pulmonary infarction which are mainly caused by embolism and infarction, rank first among various causes of death, claiming nearly 12 million lives in the world each year, which is close to a quarter of the total deaths in the world.
  • the coagulation process of human blood is composed of intrinsic pathway, extrinsic pathway and common pathway. It is a kind of fibrin that is activated by a series of coagulation factors and then strengthened and amplified.
  • the coagulation cascade The endogenous pathway (also called the contact activation pathway) and the exogenous pathway (also called the tissue factor pathway) initiate the production of coagulation factor Xa (Factor Xa, FXa for short), and then through the common pathway to generate thrombin IIa (Factor IIa for short FIIa) ), and finally form fibrin.
  • Procoagulant blood (hemostasis) and anticoagulant (antithrombotic) are opposed to each other in the human blood system and maintain a relative balance. When the function of the anticoagulation and fibrinolysis system in the body is reduced and the blood coagulation and anticoagulation functions are out of balance, coagulation occurs, causing thrombosis or embolism.
  • antithrombotic drugs that have been researched and developed mainly include anticoagulants (such as warfarin and heparin), antiplatelet aggregation drugs (such as aspirin and clopidogrel, etc.) and thrombolytic drugs ( Such as urokinase and reteplase) three categories.
  • anticoagulants such as warfarin and heparin
  • antiplatelet aggregation drugs such as aspirin and clopidogrel, etc.
  • thrombolytic drugs Such as urokinase and reteplase
  • the new therapeutic drugs show strong Market vitality is a strong competitor of heparin drugs.
  • FIIa direct thrombin
  • FXa activated coagulation factor Xa
  • the use of activated coagulation factor (FXa) inhibitors is growing rapidly because of their efficacy and safety in the prevention and treatment of thromboembolic disorders such as stroke, pulmonary embolism and venous thromboembolism (VTE). .
  • VTE venous thromboembolism
  • Factor XI is a plasma serine protease necessary to maintain the endogenous pathway. After activation, it generates activated factor XIa (FXIa), which plays a key role in the amplification process of the coagulation cascade.
  • FXIa activated factor XIa
  • thrombin can feedback and activate FXI, and the activated FXI promotes the production of thrombin in large quantities, thereby amplifying the coagulation cascade. Therefore, drugs targeting the FXI target can block the endogenous pathway and inhibit the amplification of the coagulation cascade, thereby having an antithrombotic effect.
  • FXI human coagulation factor XI
  • elevated FXI levels are associated with thrombotic diseases
  • anti-thrombotic experimental studies of animal FXI deficiency or knockout or inhibition have shown that compared with direct FXa inhibition Inhibition of FXI may reduce the risk of bleeding and is a new target for antithrombotic prevention and treatment.
  • FXI gene knockout mice can survive healthy, and their fecundity and hemostatic function are no different from wild mice. They also show activated partial thromboplastin time (aPTT) prolonged and prothrombin like FXI-deficient patients. Time (prothrombin time, T) is normal. Knockout mouse FXI gene can inhibit arterial and venous thrombosis.
  • the antithrombotic effect is equivalent to or even more effective than high-dose heparin, and is better than other drugs such as aspirin, clopidogrel or agar Traban is more effective; moreover, these antithrombotic drugs may cause a small amount of bleeding, and the tail bleeding time of mice with the FXI gene knocked out is no different from that of the wild type.
  • FXI may be a target for antithrombotic prevention and treatment with small bleeding side effects.
  • the reported FXI inhibitors mainly include monoclonal antibodies, antisense oligonucleotides, small chemical molecules, polypeptides or proteins, and polypeptide mimics.
  • Plasma kallikrein is a trypsin-like serine protease present in plasma. It is similar to the coagulation factor XIa gene and has an amino acid sequence similarity of up to 58%. In the blood, most plasma kallikrein exists in the form of a complex with high molecular weight kininogen (HMWK). Plasma kininase is involved in blood coagulation, fibrinolysis and kinin production, and plays a role in blood coagulation and many inflammatory diseases.
  • HMWK high molecular weight kininogen
  • Plasma kallikrein inhibitors may be used to treat hereditary angioedema (HAE) and advanced diabetic macular edema (advanced diabetic macular edema) and other diseases.
  • HAE hereditary angioedema
  • Advanced diabetic macular edema advanced diabetic macular edema
  • the plasma kininase inhibitor macromolecular protein drug Ecallantide (Kalbitor) has been approved by the FDA for the treatment of HAE. However, no small molecule plasma kininase inhibitor has been approved for marketing. The development of new safe and effective Kallikrein small molecule inhibitor drugs may also satisfy Unmet clinical needs.

本发明涉及式(Ⅰ)所示化合物、其光学异构体及其药效上可接受的盐,以及该化合物作为FXIa抑制剂的应用。
背景技术
血栓栓塞病是人类和动物在存活期间,由血管内形成的异常血凝块造成的疾病。血栓形成的原因有三:即血管受损、血液改变和血流淤滞;是由许多不同疾病、不同原因引起的一组并发症。由于各种基础疾病的差异,以及血栓栓塞部位的不同,血栓病的临床上可能表现为心肌梗死、中风、深度静脉血栓(deep vein thrombosis,DVT)、肺栓塞、心房颤动和脑梗死等,尤其是以栓塞和梗塞为主要诱因的心梗、脑梗和肺梗,居各种死亡原因之首,全球每年夺走近1200万人生命,接近世界总死亡人数的四分之一。
人体血液凝固过程由内源性途径(intrinsic pathway)、外源性途径(extrinsic pathway)和共同途径(common pathway)组成,是通过系列凝血因子相继被激活而后加强放大,最终形成纤维蛋白的一种凝血级联反应。内源性途径(又称接触激活途径)和外源性途径(又称组织因子途径)启动生成凝血因子Xa(Factor Xa,简称FXa),再经共同途径生成凝血酶IIa(Factor IIa,简称FIIa),最终形成纤维蛋白。促凝血(止血)与抗凝血(抗栓)在人体血液系统中互相对立并保持相对平衡。当体内抗凝纤溶系统功能降低,血液中凝血与抗凝血功能失去平衡时则出现凝血,从而引起血栓或栓塞。
随着血栓形成机制的阐明,已经研究和开发出的抗血栓药物主要有抗凝药(如华法林和肝素等)、抗血小板聚集药(如阿司匹林和氯吡格雷等)和溶栓药(如尿激酶和瑞替普酶等)三大类。国内抗凝血药物市场增长迅速,其中传统品种如肝素类药物依然占据主要份额,但市场规模逐渐趋于稳定。而新型治疗药物直接凝血酶(FIIa)抑制剂(如达比加群酯等)和活化的凝血因子Xa(FXa)抑制剂(如利伐沙班和阿哌沙班等),表现出强大的市场活力,是肝素类药物的有力竞争者。活化凝血因子(FXa)抑制剂的使用在迅速增长,因为它们的功效和安全性在预防和治疗血栓栓塞性病症如中风、肺栓塞和静脉血栓栓塞症(venous thromboembolism,VTE)等方面有良好表现。但随之而来的是与出血相关的入院率和死亡率增加,这是抗凝治疗的主要并发症。2016年,仅在美国就有约117,000例住院患者因为FXa抑制剂相关出血而死亡,相当于每月有近2000例出血相关的死亡。因此,开发具有出血倾向小的抗凝药物具有重要意义。
凝血因子XI(FXI)是维持内源性途径所必需的一种血浆丝氨酸蛋白酶原,激活后生成活化的凝血因子XIa(FXIa),在凝血级联反应放大过程中发挥关键作用。在凝血级联反应中,凝血酶可反馈激活FXI,活化的FXI又促使凝血酶的大量产生,从而使凝血级联反应放大。因此,针对FXI靶点的药物可阻断内源性途径并抑制凝血级联反应的放大,从而具有抗血栓形成的作用。近年来,有关人类凝血因子XI(FXI)缺陷或FXI水平升高与血栓性疾病发生相关的临床资料,以及动物FXI缺陷或敲除或被抑制的抗栓实验研究表明,相比直接的FXa抑制剂,抑制FXI可能会出血风险更小,是抗栓防治的新靶点。
人类FXI缺陷症,又称C型血友病,该类病人出血表型温和,很少出现自发性出血,罕见有关节出血和肌肉内出血,以此可见FXI被抑制时出血风险较小。其二,在FXI缺陷病人中,缺血性脑卒中及深静脉血栓的发病率明显降低,表明FXI被抑制有利于减少缺血性脑卒中及深静脉血栓发病风险。 其三,在有患者及对照各474人关于血栓形成倾向的研究中,高FXI水平人群的DVT发生风险是其他人群的2.2倍,表明高水平的FXI是DVT发生的危险因素,且FXI水平与DVT的发生呈正相关。另有研究表明FXI水平升高可明显增加脑卒中及静脉血栓风险,如能抑制FXI则有可能减少血栓性疾病。
FXI基因敲除小鼠能健康存活,且繁殖力和止血功能与野生小鼠无异,也与FXI缺陷病人一样表现出活化部分凝血活酶时间(activated partial thromboplastin time,aPTT)延长而凝血酶原时间(prothrombin time,T)正常。敲除小鼠FXI基因能抑制动脉及静脉血栓形成,相比于几种临床应用的抗栓药物,抗栓效果与高剂量肝素等同甚至更有效,比其他药物如阿司匹林、氯吡格雷或阿加曲班更有效;而且,这些抗栓药物可能会引起小量出血,而敲除了FXI基因的小鼠的尾出血时间与野生型的无差异。这表明FXI可能是一个出血副作用小的抗栓防治靶点。已报道的FXI抑制剂主要包括单克隆抗体、反义寡核苷酸、化学小分子、多肽或蛋白及多肽模拟物等。目前,诺华的FXIa单抗MAA-868与拜尔公司的单抗BAY1213790都已进入临床II期研究,Ionis与拜尔合作开发的FXIa反义寡核酸ISIS416858/BAY2306001/IONIX-FXIRx目前处于临床II期研究。BMS与强生合作开发的小分子口服FXIa抑制剂BMS-986177已完成了多个I期临床研究,进入了II期临床试验;日本小野公司研发的小分子口服FXIa抑制剂ONO-7684进入临床I期研究。BMS的静脉注射小分子FXIa抑制剂BMS-962122的临床I期试验已经完成。单抗和反义寡核苷酸需要注射给药,且存在价格昂贵、起效慢和可能不易控制等不足,化学小分子具有相对较好的口服生物利用度和更好的患者依从性等优势。因此,研发安全有效、特异性好和活性强的FXIa小分子抑制剂新药可能能弥补目前临床抗凝抗栓药物易出现出血并发症的不足,满足临床未满足的需求。
血浆激肽释放酶(Plasma kallikrein,PK)是一种存在于血浆中的类似于胰蛋白酶的丝氨酸蛋白酶原,与凝血因子XIa基因相似,氨基酸序列相似度高达58%。在血液中,大部分的血浆激肽释放酶以与高分子量激肽原(high molecular weight kininogen,HMWK)形成复合物的形式存在。血浆激肽酶参与血液凝固,纤溶和激肽生成,在凝血与很多炎症疾病中有作用。活化的因子XII(Factor XIIa,FXIIa)剪切前激肽释放酶(prekallikrein)形成激肽释放酶(PK),PK促进HWMK剪切形成缓激肽(Bradykinin),从而促进凝血。血浆激肽释放酶抑制剂有可能用于治疗遗传性血管神经性水肿(hereditary angioedema,HAE)以及晚期糖尿病性黄斑水肿(advanced diabetic macular edema)等疾病。血浆激肽酶抑制剂大分子蛋白药物Ecallantide(Kalbitor)已经被FDA批准治疗HAE,然而目前还没有小分子血浆激肽酶抑制剂被批准上市,研发安全有效的Kallikrein小分子抑制剂新药亦可能满足临床未满足的需求。

定义
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,“(D)”或者“(+)”表示右旋,“(L)”或者“(-)”表示左旋,“(DL)”或者“(±)”表示外消旋。

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,
