Definitions

  • the present invention relates to a pyridone or pyrimidinone derivative of the formula (I), or a stereoisomer thereof, an oxynitride, a hydrate, a solvate, a metabolite, a pharmaceutically acceptable salt or a prodrug, Process for the preparation thereof and pharmaceutical compositions containing them and use as inhibitors of factor XIa.
  • Blood coagulation is the result of coordinated activation of various plasma proteases, their cofactors, and platelets. This cascade reaction is divided into an endogenous (contact activation) pathway, an exogenous (tissue factor activation) pathway, and a common (prothrombin and thrombin generation) pathway (Gailani and Renne, 2007, Arterioscler Thromb Vasc Biol, 27, 2507-2513; Gailani and Renne, 2007, J Thromb Haemost, 5, 1106-1112; Mackman, Tilley et al., 2007, Arterioscler Thromb Vasc Biol, 27, 1687-1693). The most important physiological activating factor in blood coagulation is tissue factor.
  • tissue factor Under physiological conditions, tissue factor is expressed in the vessel wall; under the condition of the case, tissue factor is expressed in circulating monocytes and microparticles.
  • the tissue factor-factor VIIa complex catalyzes the formation of factor Xa, which in turn cleaves thrombin to produce thrombin.
  • the activation of factor XIIa catalyzes the formation of factor XIa, which in turn leads to the activation of factor IX and factor X.
  • Factor XIa only participates in endogenous pathways. In the absence of injury, abnormal thrombosis at the bottom of the vessel wall is accomplished by an endogenous pathway.
  • thrombin and tissue factor-factor VIIa complexes also activate endogenous coagulation proteases, leading to pathways that are closely associated with coagulation. Activation of coagulation and platelets completes thrombosis and hemostasis and is regulated by local plasmin (Schumacher, Luettgen et al., 2010, Arterioscler Thromb Vasc Biol, 30, 388-392).
  • Hemostasis is a beneficial process for maintaining blood in a fluid state and protecting vascular integrity.
  • Thrombosis is an unfavorable process that causes vascular occlusion and is a major cause of cardiovascular morbidity and mortality.
  • drugs currently used to treat thromboembolism They are commonly used in clinical practice as anticoagulants (such as heparin and warfarin), fibrin solvents (such as streptokinase and urokinase), and platelet inhibitors (such as aspirin).
  • anticoagulants such as heparin and warfarin
  • fibrin solvents such as streptokinase and urokinase
  • platelet inhibitors such as aspirin
  • antithrombotic heparin has a highly variable dose-dependent response whose anticoagulation must be closely monitored to avoid a serious risk of bleeding.
  • the platelet inhibitor, aspirin carries a risk of gastrointestinal bleeding at high doses. This requires the selection of a molecular target that is well differentiated between hemostasis and thrombosis. While reducing thrombin to a level sufficient to prevent thrombosis, it retains a sufficient level of hemostatic function of the thrombin maintenance mechanism (Schumacher, Luettgen et al., 2010, Arterioscler Thromb Vasc Biol, 30, 388-392).
  • factor XIa increases blood clot production and its stability.
  • Factor XIa increases thrombin generation during coagulation triggered by lower levels of tissue factor or thrombin.
  • prothrombin time (TP) is not affected by factor XIa inhibition, whereas activation of partial thrombin time aPTT by contact activation pathway is affected by factor XIa inhibition.
  • inhibition factor XIa limits the expansion of thrombin generation by endogenous cascades and has only a limited effect on the coagulation cascade of tissue factor activation (von dem Borne, Cox et al., 2006). , Blood Coagul Fibrinolysis, 17, 251-257).
  • Factor XI In addition to affecting the production of thrombin, Factor XI also acts as an antifibrinolytic agent. Factor XI-dependent amplification of thrombin generation can also result in activation of thrombin-activated plasmin inhibitors, which can cause blood clots to resist plasmin. That is to say, inhibition factor XI may directly enhance the dissolution of blood clots (Bouma, Marx et al., 2001, Thromb Res, 101, 329-354).
  • factor XI as a safe therapeutic target is strongly demonstrated in patients with hemophilia C.
  • Factor XI-deficient hemophilia C patients have only a milder bleeding phenotype compared to patients with hemophilia A (Factor VIII deficiency) or hemophilia B (Factor IX deficiency) (Gomez and Bolton-Maggs, 2008, Haemophilia, 14, 1183-1189; Duga and Salomon, 2009, Semin Thromb Hemost, 35, 416-425; Seligsohn, 2009, J Thromb Haemost, 7 Suppl 1, 84-87).
  • hemophilia C occurs in both sexes.
  • hemophilia C patients More than 180 mutation types of hemophilia C patients have a low frequency of bleeding and rarely spontaneously, usually after surgery or trauma, and are more likely to occur in tissues that are particularly prone to fibrinolysis (such as the oral or genitourinary system). Mild to moderate bleeding. Although aPTT is prolonged in patients with hemophilia C, its bleeding and clotting levels are not well correlated. Severe factor XI deficiency can cause excessive bleeding in women during menstruation, but it does not necessarily affect pregnancy and childbirth in female patients. Bleeding associated with factor XI deficiency can be corrected by factor XI replacement therapy with recombinant clotting factors.
  • Severe factor XI defects are usually hereditary coagulopathy, which is rare and variable in phenotype.
  • coagulation factor V deficiency is poorly tolerated (Asselta and Peyvandi, 2009, Semin Thromb Hemost, 35, 382-389), and the Factor X-deficient phenotype is very severe (Menegatti and Peyvandi, 2009, Semin Thromb) Hemost, 35, 407-415).
  • Factor XI can be used as a biomarker with increased levels as a risk factor for venous thrombosis and myocardial ischemia (Meijers, Tekelenburg et al., 2000, N Engl J Med, 342, 696-701; Merlo, Wuillemin et Al., 2002, Atherosclerosis, 161, 261-267; Doggen, Rosendaal et al., 2006, Blood, 108, 4045-4051; Cushman, O'Meara et al., 2009, Blood, 114, 2878-2883).
  • Factor XI can serve as an antithrombotic target.
  • the first is a transgenic mouse targeted for knockout factor XI.
  • Studies have found that targeted knockout of common pathways (factor X, factor V and prothrombin) and exogenous pathways (tissue factor and factor VII) can cause mice to die before or during perinatal period (Mackman, 2005, Arterioscler Thromb Vasc Biol, 25, 2273-2281); Although knockout mice of Factor VIII and Factor IX survive, they often experience severe bleeding, which is similar to hemophilia caused by human Factor VIII and Factor IX deficiency.
  • Factor XI knockout transgenic mice are healthy and capable of normal reproduction (Gailani, Lasky et al., 1997, Blood Coagul Fibrinolysis, 8, 134-144).
  • Factor XI deficiency protects mice against ferric chloride-induced carotid thrombosis (Rosen, Gailani et al., 2002, Thromb Haemost, 87, 774-776; Renne, Pozgajova et al., 2005, J Exp Med, 202, 271-281; Wang, Cheng et al., 2005, J Thromb Haemost, 3, 695-702; Wang, Smith et al., 2006, J Thromb Haemost, 4, 1982-1988) and cremaster Muscle laser damage-induced thrombosis (Furie and Furie, 2007, J Thromb Haemost, 5 Suppl 1, 12-17), and does not affect bleeding time and hemostatic function (Gailani, Lasky et al.
  • factor XI defects can protect carotid blood flow in the event of compression damage.
  • studies on factor XI-deficient mice have demonstrated that factor XI as a therapeutic target not only prevents obstructive thrombosis, but is also safe and tolerable.
  • experiments with antibodies, antisense nucleotides, and small chemical inhibitors of factor XI have also demonstrated that factor XI has antithrombotic effects while minimizing the impact on bleeding time.
  • factor XI/factor XIa may reduce the risk of certain thromboembolic diseases; although there are potential bleeding side effects, it is in contrast to existing blood coagulation pathways for antithrombotic use. Compared with the target (such as factor Xa, thrombin, etc.), the bleeding rate is much lower. Therefore, inhibition of factor XI may be one of the effective ways to antithrombotic therapy for patients with bleeding.
  • Factor XIASOs have the advantage of factor XIa deficiency due to the ease of reversing ASOs treatment by supplementing concentrated plasma-derived factor XIa (Zhang, Lowenberg et al., 2010, Blood, 116, 4684-4692), but its onset is relatively slow and the antithrombotic effect is relatively weak. Small molecule organic compounds have many advantages, such as better oral bioavailability and better patient compliance.

Abstract

提供一种吡啶酮或嘧啶酮衍生物及其制备方法和应用。

Description

一种吡啶酮或嘧啶酮衍生物、及其制备方法和应用 技术领域
本发明涉及一种通式(I)所示吡啶酮或嘧啶酮衍生物,或其立体异构体、氮氧化合物、水合物、溶剂化物、代谢产物、药学上可以接受的盐或前药、其制备方法以及含有它们的药物组合物以及作为凝血因子XIa抑制剂的用途。
背景技术
血液凝固是各种血浆蛋白酶、其共因子和血小板协调激活的结果。这一级联反应被分成内源性(接触激活)途径、外源性(组织因子激活)途径和共同(凝血酶原和凝血酶的产生)途径(Gailani and Renne,2007,Arterioscler Thromb Vasc Biol,27,2507-2513;Gailani and Renne,2007,J Thromb Haemost,5,1106-1112;Mackman,Tilley et al.,2007,Arterioscler Thromb Vasc Biol,27,1687-1693)。在血液凝固过程中,最重要的生理学激活因子是组织因子。在生理条件下,组织因子表达在血管壁;在病例条件下,组织因子表达在循环单核细胞和微粒中。组织因子-因子VIIa复合物催化形成因子Xa,因子Xa进而裂解凝血酶素产生凝血酶。在内源性凝血途径中,通过接触激活因子XIIa,催化形成因子XIa,进而导致因子IX和因子X的激活。因子XIa仅仅参与到内源性的通路中。在没有损伤的情况下,血管壁底部异常形成血栓是通过内源性途径完成的。另外,凝血酶和组织因子-因子VIIa复合物也能激活内源性的凝固蛋白酶,导致与凝血产生紧密关联的通路。凝血和血小板的激活完成了血栓形成和止血,并且受到局部纤维蛋白溶酶的调节(Schumacher,Luettgen et al.,2010,Arterioscler Thromb Vasc Biol,30,388-392)。
止血是维持血液呈液体状态和保护血管完整性的的有利过程。血栓形成则是造成血管阻塞的不利过程,是造成心血管发病和致死的主要因素。目前用于治疗血栓栓塞的药物有很多,常用于临床的分为抗凝血药(如肝素和华法林),纤维蛋白溶剂剂(如链激酶和尿激酶),血小板抑制剂(如阿司匹林)。但是,这些用于治疗心血管疾病的抗血栓药物都具有药物相关的副作用——出血。例如:抗血栓的肝素具有高度可变的剂量依赖的应答,其抗凝作用必须被密切监控,以避免严重的出血风险。而血小板抑制剂阿司匹林在高剂量下会有胃肠道出血的风险。这就需要选择一个分子靶点能够很好地区分止血和血栓形成。在使凝血酶减少到足以阻止血栓形成的水平的同时,又能保留足够水平的凝血酶维持机制的止血功能(Schumacher,Luettgen et al.,2010,Arterioscler Thromb Vasc Biol, 30,388-392)。
在体外,因子XIa能增加血凝块的产生和其稳定性。在由较低水平的组织因子或凝血酶触发的凝固过程中,因子XIa能增加凝血酶的产生。在有较高水平的组织因子激活的凝固过程中,其凝血酶原时间(TP)不受因子XIa抑制的影响,而接触激活途径的活化的部分凝血酶时间aPTT则受到因子XIa抑制的影响。因此,抑制因子XIa能限制通过内源性的级联反应造成的凝血酶产生的扩增,同时对组织因子激活的凝固级联反应仅有有限的影响(von dem Borne,Cox et al.,2006,Blood Coagul Fibrinolysis,17,251-257)。
除了影响凝血酶的产生,因子XI还发挥着抗纤维蛋白溶解的作用。因子XI依赖的凝血酶产生的扩增也会导致凝血酶激活的纤维蛋白溶酶抑制物的激活,该抑制物会使血凝块对纤维蛋白溶酶产生抵抗。即是说,抑制因子XI可能会直接增强血凝块的溶解(Bouma,Marx et al.,2001,Thromb Res,101,329-354)。
因子XI作为安全的治疗靶点的潜力在血友病C患者身上得到有力的证实。因子XI缺陷的血友病C患者与血友病A(因子VIII缺陷)或血友病B(因子IX缺陷)患者相比,仅具有较轻微的出血表型(Gomez and Bolton-Maggs,2008,Haemophilia,14,1183-1189;Duga and Salomon,2009,Semin Thromb Hemost,35,416-425;Seligsohn,2009,J Thromb Haemost,7Suppl 1,84-87)。不同于血友病A、B,血友病C在两种性别的人群身上都有发生。超过180种突变类型的血友病C患者出血频率较低且很少自发产生,通常是在手术后或外伤时,更容易在特别倾向于纤维蛋白溶解的组织(如口腔或泌尿生殖系统)出现轻中度的出血。虽然血友病C患者的aPTT会有所延长,但其出血和凝血水平并不太相关。严重因子XI缺陷会引起女性患者经期出血过多,但并不一定会影响女性患者的怀孕和分娩。与因子XI缺陷相关的出血可以通过重组的凝血因子进行因子XI替代疗法得以纠正。严重的因子XI缺陷通常是遗传的凝血紊乱,该类患者较罕见,且表型可变。相比之下,凝血因子V缺陷的耐受较差(Asselta and Peyvandi,2009,Semin Thromb Hemost,35,382-389),凝血因子X缺陷表型则非常严重(Menegatti and Peyvandi,2009,Semin Thromb Hemost,35,407-415)。
虽然现有有限的研究不能证明因子XI缺陷能够保护患者免受急性心肌缺血,却暗示可以降低缺陷病人发生缺血性中风和深静脉血栓的风险(Seligsohn,2009,J Thromb Haemost,7Suppl 1,84-87;Salomon,Steinberg et al.,2011,Thromb Haemost,105,269-273)。研究显示因子XI可以用作生物标记,其增加的水平可以作为静脉栓塞和心肌缺血的风险因子(Meijers,Tekelenburg et al.,2000,N Engl J Med,342,696-701;Merlo,Wuillemin et al.,2002,Atherosclerosis,161,261-267;Doggen,Rosendaal et al.,2006,Blood,108,4045-4051; Cushman,O′Meara et al.,2009,Blood,114,2878-2883)。
动物实验为因子XI能够作为抗血栓栓塞靶点提供了大量证据。首先就是靶向敲除因子XI的转基因小鼠。研究发现,共同通路(因子X、因子V和凝血酶原)和外源性通路(组织因子和因子VII)的靶向敲除会导致小鼠在产前或围产期致死(Mackman,2005,Arterioscler Thromb Vasc Biol,25,2273-2281);因子VIII和因子IX的基因敲除小鼠虽然能够存活,但常会出现严重的出血,症状类似于人类因子VIII和因子IX缺陷引起的血友病。而因子XI敲除的转基因小鼠健康且能够正常繁殖(Gailani,Lasky et al.,1997,Blood Coagul Fibrinolysis,8,134-144)。同时,因子XI缺陷能够保护小鼠能够抵抗氯化铁诱导的颈动脉血栓的形成(Rosen,Gailani et al.,2002,Thromb Haemost,87,774-776;Renne,Pozgajova et al.,2005,J Exp Med,202,271-281;Wang,Cheng et al.,2005,J Thromb Haemost,3,695-702;Wang,Smith et al.,2006,J Thromb Haemost,4,1982-1988)和提睾肌激光损伤诱导的血栓形成(Furie and Furie,2007,J Thromb Haemost,5 Suppl 1,12-17),并且不影响出血时间和止血功能(Gailani,Lasky et al.,1997,Blood Coagul Fibrinolysis,8,134-144;Gailani,2001,Front Biosci,6,D201-207;Rosen,Gailani et al.,2002,Thromb Haemost,87,774-776)。另外,因子XI缺陷还能在受到压迫损伤的情况下,保护颈动脉血流。综上所述,对因子XI缺陷小鼠的研究证明因子XI作为治疗靶点,不仅能够防止阻塞性血栓,而且是安全易耐受的。相似地,在大鼠、兔和灵长类上,运用抗体、反义核苷酸和化学小分子抑制因子XI的实验也证实了因子XI具有抗血栓栓塞的作用同时使对出血时间的影响最小化(Gruber and Hanson,2003,Blood,102,953-955;Deng,Bannister et al.,2006,Bioorg Med Chem Lett,16,3049-3054;Lin,Deng et al.,2006,J Med Chem,49,7781-7791;Yamashita,Nishihira et al.,2006,J Thromb Haemost,4,1496-1501;Schumacher,Seiler et al.,2007,Eur J Pharmacol,570,167-174;Livnat,Tamarin et al.,2009,Thromb Haemost,102,487-492;Tucker,Marzec et al.,2009,Blood,113,936-944;Wong,Crain et al.,2011,J Thromb Thrombolysis,32,129-137;Crosby,Marzec et al.,2013,Arterioscler Thromb Vasc Biol,33,1670-1678)。
大量的人和实验动物中的发现都表明靶向因子XI/因子XIa可能减少某些血栓栓塞疾病的风险;虽然有潜在的出血的副作用,但是与现有的用于抗血栓的血液凝固通路中的靶点(如因子Xa、凝血酶等)相比,其出血率要低的多。因此抑制因子XI可能是目前针对可出血患者进行抗血栓治疗的有效途径之一。
目前靶向因子XI的候选药物还较少,包括因子XI抗体、因子XI反义核苷酸(ASOs)、蛋白或多肽类、化学小分子和一种从海绵提取分离得到的天然产物。因子XIASOs虽然具有易于通过补充浓缩的血浆来源的因子XIa逆转ASOs治疗造成的因子XIa缺乏的优势 (Zhang,Lowenberg et al.,2010,Blood,116,4684-4692),但其起效相对缓慢,且抗血栓的效果相对较弱。小分子的有机化合物具有许多优势,例如较好的口服生物利用度和更好的患者依从性。
