Definitions
- the present invention relates to the field of medicinal chemistry, and in particular to novel bicyclic compounds and preparation methods thereof, pharmaceutical compositions using the compounds as active ingredients, and their use in the preparation of a medicament for treating diseases associated with Lp-PLA 2 enzyme activity .
- Lipoprotein-associated phospholipase A 2 (Lp-PLA 2 ), also known as platelet-activating factor acetylhydrolase (PAF-AH), contains 441 amino acids with a relative molecular mass of 45 kD. 70% of Lp-PLA 2 in human plasma binds to low-density lipoprotein (LDL), and 30% of Lp-PLA 2 binds to high-density lipoprotein (HDL).
- LDL low-density lipoprotein
- HDL high-density lipoprotein
- Lp-PLA 2 can rapidly hydrolyze oxidized phosphatidylcholine into lysophosphatidylcholine (1yso-PC) and oxidized non-esterified fatty acid (ox-NEFA), while lyso-PC and ox-NEFA are very strong. It promotes inflammation and activates the inflammatory/immune response of various cells including endothelial cells, smooth muscle cells, monocytes/macrophages, T cells, and neutrophils.
- Lp-PLA 2 inhibitors may be universally applicable to any condition in which the lipid involved in oxidation is hydrolyzed into two inflammatory traits with the participation of Lp-PLA 2 .
- These include atherosclerosis, diabetes, diabetic eye disease, diabetic brain disease, hypertension, angina pectoris, rheumatoid arthritis, stroke, myocardial infarction, ischemia and reperfusion, psoriasis, and brain inflammatory diseases (such as: Alzheimer's disease), various neuropsychiatric diseases (such as: schizophrenia), ischemia-reperfusion injury, sepsis, acute and chronic inflammatory diseases.
- Atherosclerosis is not only related to abnormal blood lipid levels, but also an inflammation-related disease. Inflammatory factors that inhibit atherosclerosis are new ways to treat the disease. Studies have shown that lyso-PC can promote the development of atherosclerotic plaque and eventually form a necrotic core. Experiments conducted on a diabetic high cholesterol pig model confirmed that Lp-PLA 2 inhibitors can affect the arteriosclerotic plaque volume, composition and gene expression of diabetic high cholesterol pigs, and effectively inhibit the continued growth of atherosclerotic plaques.
- Lyso-PC acts as a pro-inflammatory factor that induces the release of multiple cytotoxic inflammatory cytokines, whereas Lp-PLA 2 inhibitors attenuate inflammatory responses by inhibiting the production of lyso-PC.
- Lp-PLA 2 inhibitors can improve blood brain barrier (BBB) function, reduce blood-brain barrier (BBB) permeability, and alleviate beta-like protein in the brain. precipitation.
- BBB blood brain barrier
- BBB blood-brain barrier
- Lp-PLA 2 inhibitors can inhibit lyso- The production of PC is used to treat diabetes-related tissue damage. Considering that local inflammatory reactions play an important role in the development of diabetic retinopathy, it is speculated that Lp-PLA 2 inhibitors can be used for the treatment of diabetic eye diseases.
- BRB blood-retinal barrier
- DME diabetic macular edema
- Lp-PLA 2 inhibitors can reduce BRB permeability
- studies have shown that Lp-PLA 2 inhibitors may Used in the treatment of diabetic macular edema.
- Glaucoma and age-related macular degeneration are retinal neurodegenerative diseases, and studies have shown that inflammatory responses, including: TNF- ⁇ signaling pathway may play an important role in these two diseases.
- Lp-PLA 2 inhibitors can block the release of inflammatory cytokines, it is speculated that Lp-PLA 2 inhibitors can be used in the treatment of glaucoma and AMD.
- GlaxoSmithKline has developed a class of potent reversible inhibitors of Lp-PLA 2 (WO 99/24420, WO 01/60805, WO 02/30911, WO 03/016287, WO 03/042179, WO 03/042206, WO 08/048867, etc., characterized by a bicyclo or pyridone group in the structure, and the representative compounds darapladib and rilapladib are currently in clinical research.
- GlaxoSmithKline has also developed a class of Lp-PLA 2 inhibitors (US 2012/0142717, WO 2012/075917, WO 2012/037782, WO 2013/013503, WO 2013/014185, WO 2014/114248, WO 2014/114249 , WO 2014/114694), the structure is also characterized by a bicyclic group, which differs from the previous class of reversible inhibitors in that the structure is linear and the molecular weight is relatively small.

Abstract
本发明涉及用作Lp-PLA2抑制剂的双环类化合物、其制备方法和医药用途,以及包含该化合物的药物组合物,所述双环类化合物的结构如通式I所示, R1, R2, R3, X, Y, Z, Ar, n的定义如说明书和权利要求书所示。本发明的通式I化合物可用作Lp-PLA2抑制剂, 预防和/或治疗和/或改善与Lp-PLA2酶活性有关的疾病。,
Description
本发明涉及药物化学领域,尤其涉及新颖的双环类化合物及其制备方法,以该类化合物为活性成分的药物组合物,以及它们在制备治疗与Lp-PLA2酶活性有关疾病的药物中的应用。
脂蛋白相关的磷脂酶A2(Lp-PLA2)也称血小板激活因子乙酰水解酶(PAF-AH),该酶含有441个氨基酸,相对分子质量为45kD。人血浆中70%的Lp-PLA2与低密度脂蛋白(LDL)结合,30%的Lp-PLA2与高密度脂蛋白(HDL)结合。Lp-PLA2能迅速地将氧化的磷脂酰胆碱水解成为溶血磷脂胆碱(1yso-PC)以及氧化非酯化脂肪酸(ox-NEFA),而lyso-PC和ox-NEFA都具有很强的促炎症作用,能够启动包括内皮细胞、平滑肌细胞、单核/巨噬细胞、T细胞、嗜中性粒细胞在内的多种细胞的发炎/免疫反应。
Lp-PLA2抑制剂可能普遍适用于任何涉及到氧化的脂质在Lp-PLA2的参与下水解成为两个炎症特性物质这一过程的病症。这其中包括动脉粥样硬化、糖尿病、糖尿病眼部疾病、糖尿病脑部疾病、高血压、心绞痛、类风湿性关节炎、中风、心肌梗死、缺血和再灌注后、牛皮癣、脑部炎症疾病(如:阿尔茨海默症)、各类神经精神疾病(如:精神分裂症)、缺血再灌注损伤、败血症、急性和慢性炎症疾病。
动脉粥样硬化不只是与血脂水平异常有关,也是一种炎症相关性疾病,抑制动脉粥样硬化的炎症因子是治疗该疾病的新途径。有研究表明,lyso-PC能够促进动脉粥样硬化斑块发展,并最终形成坏死核心。在糖尿病高胆固醇猪模型上进行的实验证实Lp-PLA2抑制剂能够影响糖尿病高胆固醇猪的动脉硬化斑块体积、组成和基因表达的情况,并且有效抑制动脉粥样硬化斑块的继续生长。
有研究指出在所有的神经退行性疾病当中,比如:多发性硬化症、帕金森病、阿尔茨海默症等,均表现出了神经炎症。Lyso-PC作为一个前炎症因
子,能够诱导释放多种细胞毒性炎症细胞因子,而Lp-PLA2抑制剂能够通过抑制lyso-PC的产生来减弱炎症反应。
在糖尿病高胆固醇猪模型上进行的实验表明,Lp-PLA2抑制剂能够改善血脑屏障(blood brain barrier,BBB)功能,降低血脑屏障(BBB)渗透性,并且能够缓解脑中β样蛋白沉淀。这些研究结果表明Lp-PLA2抑制剂可能可以应用于与血脑屏障损伤相关联的疾病的治疗,比如糖尿病脑病,阿尔茨海默症。
由于lyso-PC参与白细胞激活、诱导细胞凋亡并且能够介导内皮细胞功能失调,而糖尿病能够引起持续的血管炎症并且增加活性氧的产生,因此普遍认为Lp-PLA2抑制剂可以通过抑制lyso-PC的产生,从而用于治疗糖尿病相关的组织损伤。考虑到局部的炎症反应在糖尿病视网膜病变的发生发展过程中起着重要作用,因此推测Lp-PLA2抑制剂可以应用于糖尿病性眼病的治疗。
另外,血视网膜屏障(BRB)的破坏是糖尿病黄斑水肿(DME)患者的共同病理特征。正常情况下,BRB可通过主动和被动转运阻止血浆成份自由进入视网膜,维持视网膜内感受器细胞的自身稳定性。一旦BRB遭到破坏,将不能严格控制血浆内蛋白和水分进入视网膜实质层,导致视网膜细胞外间隙明显扩张,在黄斑区就表现为黄斑水肿。在链脲佐菌素(STZ)诱导的SD大鼠以及棕色挪威大鼠模型上进行的动物实验显示,Lp-PLA2抑制剂能够降低BRB渗透性,研究结果显示Lp-PLA2抑制剂可能可以应用于糖尿病黄斑水肿的治疗。
青光眼以及年龄相关的黄斑变性(AMD)均为视网膜神经退行性疾病,研究显示炎症反应,包括:TNF-α信号通路可能在这两种疾病当中起着重要的作用。考虑到Lp-PLA2抑制剂可以阻断炎症细胞因子的释放,因此推测Lp-PLA2抑制剂可以应用于青光眼以及AMD的治疗。
葛兰素史克开发了一类Lp-PLA2的强效可逆抑制剂(WO 99/24420,WO 01/60805,WO 02/30911,WO 03/016287,WO 03/042179,WO 03/042206,WO 08/048867等),以结构中含有双环或吡啶酮基团为特征,代表化合物darapladib以及rilapladib目前正处于临床研究阶段。
葛兰素史克还开发了一类Lp-PLA2抑制剂(US 2012/0142717,WO 2012/075917,WO 2012/037782,WO 2013/013503,WO 2013/014185,WO 2014/114248,WO 2014/114249,WO 2014/114694),结构也以双环基团为特
征,与之前一类可逆抑制剂的区别在于该类结构为线性结构,分子量也相对较小。
本领域尚需对Lp-PLA2抑制剂进行深入的研究和开发。
