Definitions

  • the present invention belongs to the field of biomedicine, and specifically relates to a nitrogen-containing heterocyclic compound with PPAR agonist activity.
  • the present invention also relates to a preparation method of the compound and its medical use as a PPAR agonist.
  • Non-alcoholic steatohepatitis is a disease that seriously threatens human health. Its main characteristics are hepatocyte fatty degeneration accompanied by hepatocyte damage and inflammation, which can further develop into liver fibrosis, cirrhosis, liver failure or hepatocellular carcinoma. Currently, there is no specific treatment for this disease (Nature Reviews Endocrinology, 2017, 13(1):36). Peroxisome proliferator-activated receptors (PPARs) are a class of nuclear receptors.
  • PPAR retinoid receptors
  • RXR retinoid receptors
  • the activation of PPAR has the effect of inhibiting inflammation (Journal of Hepatology 2015, 720; Science, 2003, 302(5644): 453), so it may be used to intervene in the development of non-alcoholic fatty liver disease.
  • PPAR has three subtypes, namely PPAR ⁇ , PPAR ⁇ , and PPAR ⁇ . The three subtypes have different tissue distributions and play corresponding functions.
  • PPAR ⁇ is mainly distributed in the liver and is mainly involved in the oxidation of fatty acids in the liver.
  • PPAR ⁇ is widely distributed in the body, mainly in skeletal muscle and liver, and is involved in fatty acid transport and oxidation.
  • PPAR ⁇ is highly expressed in adipocytes and is involved in processes such as adipocyte differentiation (Nature Reviews Endocrinology, 2017, 13(1): 36).
  • PPAR agonists for the treatment of non-alcoholic steatohepatitis are still under development.
  • the PPAR ⁇ / ⁇ dual agonist GFT-505 (Elafibranor) developed by Genfit failed in the phase III clinical trial against NASH (NCT02704403, phase III).
  • the PPAR ⁇ / ⁇ / ⁇ triple agonist IVA337 developed by Inventiva is currently undergoing a phase III clinical study against NASH (NCT03008070, phase II). So far, no PPAR agonist for the treatment of non-alcoholic steatohepatitis has been marketed.

Description

含氮杂环类化合物及其医药用途 技术领域
本发明属于生物医药领域,具体涉及一种具有PPAR激动活性的含氮杂环类化合物,本发明还涉及该类化合物的制备方法及其作为PPAR激动剂的医药用途。
背景技术
非酒精性脂肪性肝炎(non-alcoholic steatohepatitis,NASH)是严重威胁人类健康的疾病,主要特征为肝细胞脂肪变伴肝细胞损伤和炎症,可进一步发展为肝纤维化、肝硬化、肝功能衰竭或肝细胞癌,目前尚缺少针对该疾病的特异性治疗方法(Nature Reviews Endocrinology,2017,13(1):36)。过氧化物酶体增殖物激活受体(peroxisome proliferators-activated receptors,PPARs)是一类核受体,当配体激活PPARs后,配体激活的转录因子PPARs与类维甲酸受体(RXR)形成异二聚体,并与特定的DNA序列结合,促进靶基因的转录,以此来发挥生物学效应(Nature Reviews Immunology,2006,6(1):44)。PPAR的激活具有抑制炎症的作用(Journal of Hepatology 2015,720;Science,2003,302(5644):453),因此有可能用来干预非酒精性脂肪肝炎的发展。PPAR具有三种亚型,分别是PPARα,PPARδ,PPARγ,三种亚型具有不同的组织分布,发挥相应的功能。PPARα主要分布在肝脏,主要参与肝脏脂肪酸的氧化过程。PPARδ在体内分布广泛,主要分布在骨骼肌和肝脏,参与脂肪酸转运,氧化等过程。PPARγ高表达于脂肪细胞,参与脂肪细胞分化等过程(Nature Reviews Endocrinology,2017,13(1):36)。
目前用于治疗非酒精性脂肪肝炎的PPAR激动剂仍处于在研阶段。其中由Genfit公司开发的PPARα/δ双重激动剂GFT-505(Elafibranor)抗NASH三期临床试验失败(NCT02704403,phase III)。由Inventiva公司开发的PPARα/δ/γ三重激动剂IVA337目前正在进行抗NASH三期临床研究(NCT03008070,phase II)。迄今尚未有治疗非酒精性脂肪肝炎的PPAR激动剂上市。

小鼠按照体重随机分成5组:对照组(Control)、模型组(Model)、阳性药IVA337组(IVA337 10mpk)、化合物143低剂量组(Com 143 3mpk),化合物143中剂量组(Com 143 10mpk)和化合物143高剂量组(Com 143 30mpk)。
2、造模与给药
小鼠适应性喂养1周后,Model组、阳性药IVA337组、化合物143低剂量组、化合物143中剂量组和化合物143高剂量组腹腔注射25%四氯化碳(溶于葵花籽油)造模 (1周2次)。同时,ND组小鼠和Model组小鼠每日灌胃给予体积分数为0.5%CMC-Na溶液,阳性药IVA337组每日灌胃给予阳性药IVA337(剂量为10mpk),化合物143低剂量组每日灌胃给予3mpk的化合物143,化合物143中剂量组每日灌胃给予10mpk的化合物143,化合物143高剂量组每日灌胃给予30mpk的化合物143。给药时间为3周,每周对小鼠称重,仔细观察并记录其体重、毛发、粪便及活动情况。
3、取材
在最后一次注射四氯化碳24小时后,处死小鼠取肝脏。肝脏右小叶组织用4%多聚甲醛固定,用于HE染色切片。部分肝组织分成3份,液氮速冻,以备后续其他指标检测。
4、羟脯氨酸含量测定
按照生产商的方案,采用羟脯氨酸(HYP)含量测定试剂盒(南京建成生物工程研究所有限公司)测定羟脯氨酸水平。使用组织重量对数据进行归一化。
5、肝脏组织学分析
将肝尾状叶在4%多聚甲醛中固定过夜,进行标准组织学处理,石蜡包埋。将样品切割至4μm厚,用H&E或天狼猩红染色。所有切片均采用Nano-Zoomer 2.0RS扫描。
6、实验结果
切片染色以评估肝纤维化生物标志物的水平。如图4天狼星红染色所示,与对照组相比,模型组胶原蛋白含量明显增加,经化合物143处理后胶原蛋白积累明显减轻。进一步肝脏羟脯氨酸(Hyp)分析表明(图5),化合物143可以降低小鼠肝脏羟脯氨酸含量,表明化合物143可以降低胶原蛋白水平。此外,H&E染色数据也显示化合物143可以减少门静脉区炎症细胞浸润(图6)。此外,化合物143的抗纤维化作用与IVA337(10mg/kg)相当,且在剂量为30mg/kg时,化合物143组更优。综上所述,化合物143改善了四氯化碳诱导的肝纤维化小鼠模型中的胶原沉积并抑制了炎症细胞浸润。
以上结果表明,化合物143对于肝纤维化模型小鼠具有显著地改善保护作用。本发明的其他化合物也具有类似的性质,提示此类化合物可以用于预防和治疗肝纤维化及其相关疾病。
