Definitions

  • the invention relates to the field of medicinal chemistry, in particular to a plasmin inhibitor, its preparation method and its application in the pharmaceutical field.
  • Plasmin is a proteolytic enzyme that degrades fibrin.
  • the hemostatic mechanism is triggered: vasoconstriction, platelet plug formation, initiation of the coagulation process, and eventual formation of stable fibrin.
  • the fibrinolytic system is activated, which maintains a balance between the formation and cleavage of fibrin, and plays a role in maintaining vascular patency and remodeling the damaged blood vessel wall in the process of repairing damaged blood vessel walls. damage tissue (Tengborn L, M, Berntorp E. Thromb Res. 2015 Feb;135(2):231-42).
  • the fibrinolytic system includes plasminogen, tissue-type plasminogen activator (tPA) and urokinase-type plasminogen activator (uPA).
  • Plasminogen binds to lysine residues on the surface of fibrin and is converted to plasmin by an activator (ie, tPA) released from endothelial cells.
  • Fibrinolysis inhibition can be used to treat bleeding.
  • Antifibrinolytic use can reduce blood loss in cardiac surgery, trauma, orthopaedic surgery, solid organ transplantation, obstetrics and gynecology, neurosurgery and non-surgical diseases (Ng W, Jerath A, M. Anaesthesiol Intensive Ther.
  • Tranexamic acid is a synthetic lysine derivative and antifibrinolytic agent that forms a reversible complex with plasminogen. By combining with plasminogen, it blocks the interaction of plasminogen and plasmin heavy chain with fibrin lysine residues, thereby preventing the combination of plasminogen and fibrin surface, thereby delaying fibrinolysis.
  • Tranexamic acid has been approved for the treatment of severe menstrual bleeding and various surgical bleeding disorders, and is currently the most commonly used hemostatic drug in clinical practice. However, a large number of literature reports show that tranexamic acid is prone to gastrointestinal adverse reactions after oral administration, such as nausea, vomiting, diarrhea, and indigestion, and its dosage is large, which may cause complications such as epilepsy in patients.
  • aminocaproic acid Other similar hemostatic drugs, such as aminocaproic acid, have problems such as rapid excretion from the human body, weak hemostatic effect, short duration of action and more toxic reactions.
  • the mechanism of aminotoluic acid is the same as that of aminocaproic acid, and its effect is 4 to 5 times stronger than that of aminocaproic acid. It has a significant effect on general chronic bleeding, but has no hemostatic effect on trauma bleeding and cancer bleeding. In addition, excessive dosage can also promote thrombosis.
  • Aprotinin a hemostatic drug commonly used in heart bypass surgery, was also withdrawn from the market by the FDA in 2008 because it could induce renal failure, myocardial infarction, and heart failure.
  • Hemostatic drugs with other mechanisms such as carbachol, which acts on blood vessels, can induce epilepsy with repeated use; thrombin, a hemostatic drug that promotes the coagulation process, can only be used for gastrointestinal bleeding or local bleeding.
  • One of the objectives of the present invention is to overcome the above-mentioned defects of the prior art and provide a new compound with coagulation and hemostatic activities.

Abstract

涉及可以抑制纤溶酶活性,具有凝血、止血活性的式(I)的化合物,其药学上可接受的盐、水合物、异构体、前药及混合物,其中R 1至R 3如说明书中所定义。

Description

一种纤溶酶抑制剂、其制备方法及应用 技术领域
本发明涉及医药化学领域,具体涉及一种纤溶酶抑制剂、其制备方法及在制药领域的应用。
背景技术
纤溶酶是一种蛋白水解酶,可降解纤维蛋白。当组织受损造成血管破裂时,会触发止血机制:血管收缩,血小板栓塞形成,凝结过程启动,最终形成稳定的血纤蛋白。与此同时,由于血纤蛋白的沉积,纤溶系统被激活,该系统在血纤蛋白的形成和裂解之间保持平衡,在修复受损血管壁的过程中,发挥维持血管畅通并重塑受损组织的作用(Tengborn L,
Figure PCTCN2022074754-appb-000001
M,Berntorp E.Thromb Res.2015 Feb;135(2):231-42)。
纤溶系统包括纤溶酶原,组织型纤溶酶原激活物(tPA)和尿激酶型纤溶酶原激活物(uPA)。纤溶酶原与纤维蛋白表面的赖氨酸残基结合,通过从内皮细胞释放的活化剂(即tPA)转化为纤溶酶。纤维蛋白溶解抑制可用于治疗出血。抗纤溶药的使用可以减少心脏手术,创伤,骨科手术,实体器官移植,妇产科,神经外科和非外科疾病中的失血(Ng W,Jerath A,
Figure PCTCN2022074754-appb-000002
M.Anaesthesiol Intensive Ther.2015;47(4):339-50)。1950年初,人们发现赖氨酸氨基酸抑制了纤溶酶原的活化,但是作用太弱,无法用于治疗纤维蛋白溶解性出血病。1953年,Shosuke Okamoto等研究显示几种巯基和氨基碳酸具有抗血浆蛋白的作用,并发现赖氨酸的合成衍生物ε-氨基己酸(EACA)对纤溶酶原具有很强的抑制作用。EACA已在临床上被广泛使用,但是除了轻微的胃肠道副作用如恶心之外,还需要较大剂量。1962年,4-氨基-甲基-环己烷-碳酸(AMCHA)被发现,该化合物包含两个立体异构体,进一步研究表明其反式形式(反式-4-氨基甲基环己烷甲酸,即氨甲环酸,TXA)具有抗纤维蛋白溶解能力,活性是EACA的10倍左右,并且被证明具有更强的耐受性(Tengborn L,
Figure PCTCN2022074754-appb-000003
M,Berntorp E.Thromb Res.2015 Feb;135(2):231-42)。
氨甲环酸是一种合成的赖氨酸衍生物和抗纤溶剂,能与纤溶酶原形成可逆的复合物。通过与纤溶酶原结合,阻断纤溶酶原及纤溶酶重链与纤维蛋白赖氨酸残基的相互作用,从而阻止纤溶酶原与纤维蛋白表面的结合,进而延缓纤溶。氨甲环酸已被批准用于治疗严重的月经 出血和各种外科出血性疾病,是目前临床上最常用的止血药物。然而,大量文献报道显示,氨甲环酸口服后容易产生胃肠道,如恶心,呕吐,腹泻和消化不良等不良反应,且其给药剂量较大,患者用药后可能引发癫痫等并发症。
其他同类止血药物,如氨基己酸,存在人体内排泄较快,止血效果弱、作用持续的时间短且毒性反应较多等问题,当用量过多时可形成血栓,限制了在有血栓形成倾向或有血栓性血管疾病病史者及肾功能不全者上的应用。氨甲苯酸机制同氨基己酸,作用较氨基己酸强4~5倍。对一般慢性渗血效果较显著,但对创伤出血以及癌症出血无止血作用。此外,用量过大也可促进血栓形成。在心脏搭桥手术中常用的止血药物抑肽酶也因可诱发肾衰竭、心肌梗死、心力衰竭等原因,于2008年被FDA从市场撤回。
其他机制的止血药物,如作用于血管的卡巴克络,反复使用可诱发癫痫;促进凝血过程的止血药凝血酶,仅可应用于胃肠道出血或局部出血。
鉴于临床上可选择的止血药物十分有限,在使用剂量、临床适应症等方面或多或少存在一定缺陷,且现有同类型药物均存在用药剂量大、不良反应多,易引发癫痫等并发症等问题,有必要开发一种新的止血药物,以更好的满足临床需求。
发明内容
本发明的目的之一是克服现有技术的上述缺陷,提供一种具有凝血、止血活性的新化合物。

1.实验目的
测定本发明化合物对人血浆凝块降解的抑制作用。
2.实验材料及仪器
Figure PCTCN2022074754-appb-000136
3.实验步骤
3.1采集新鲜健康人血液,用0.109M柠檬酸三钠作为抗凝剂,以1份抗凝剂+9份血液进行混合,室温2000x g离心20分钟,收集上清液(即血浆),分装后于-80℃保存备用。
3.2实验当天,将血浆在37℃的水浴中解冻,除tPA外,所有试剂均置于37℃预热。
3.3于96孔板中加入12.5μL,80mM的CaCl 2(HEPES buffer,pH 7.4),再分别加入25μL用生理盐水稀释的不同浓度的待测化合物,阴性对照孔加入等体积的生理盐水。
3.4将50μL预热的血浆与12.5μL,4nM的tPA混合(HEPES buffer,pH 7.4),立即加入96孔板中,于405nm处检测吸收值,每2分钟读值一次,连续测定15小时。
3.5吸收值随时间变化,先上升后降低,下降段吸收值中位数对应时间-上升段吸收值中位数对应时间,即为血浆凝块降解时间(Clot lysis time)。以阴性对照孔血浆凝块降解时间为参照,计算相对于不同浓度化合物孔中的血浆凝块降解时间,得到抑制率:
抑制率%=(1-阴性对照孔 Clot lysis time/化合物孔 Clot lysis time)×100%
3.6拟合量效曲线
以化合物浓度的log值作为X轴,百分比抑制率为Y轴,采用分析软件GraphPad Prism 5的log(抑制剂)vs.响应-可变斜率(Variable slope)拟合量效曲线,从而得出各个化合物对细胞活性的IC 50值。
计算公式:Y=min+(max-min)/(1+10^((LogIC 50-X)×Hillslope))。
本发明化合物血浆凝块降解的抑制作用通过以上的试验进行测定,计算得到本发明化合物的IC 50值均明显低于目前临床上常用的止血药物氨甲环酸,例如本发明实施例1的化合物的血浆凝块降解的抑制IC50仅为氨甲环酸的1/4。本发明在体外相对于氨甲环酸的相对凝血活性(IC 50ratio=IC 50实施例/IC 50氨甲环酸)见下表:
