Description
技术领域
本发明涉及一种嘧啶甲酰胺类化合物及其应用。
背景技术
Vanin-1(血管非炎性分子-1)是一种具有泛肽酶活性的外切酶,主要催化泛酰巯基乙胺的水解而产生泛酸(pantothenic acid,VB5)和巯基乙胺。由VB5合成而来的辅酶A(CoA)调节脂肪酸合成和氧化以及能力代谢等生物转化,而巯基乙胺和胱胺之间的可逆反应是氧化应激的重要传感器。越来越多的研究发现,巯基乙胺的缺乏或水平降低导致γ-GCS活性增强,引起组织中内源性GSH储备升高,从而可以预防或消除组织炎症。研究发现,Vanin-1的mRNA在人结肠、十二指肠、子宫内膜、肝、肾、胆囊和小肠中高表达。在UC(溃疡性结肠炎)患者中,Vanin-1高表达且弥漫,而且仅限于笔刷边界。另外,在UC的临床静止期,结肠中Vanin-1的表达水平仍显著高于对照品。在TNBS模型实验中,小鼠Vanin-1敲除(Vanin-1-/-)后生存率明显高于模型对照组,并且未表现明显体重降低。而且,90%经胱胺处理的Vanin-1-/-小鼠在5天内死亡,说明胱胺完全逆转 Vanin-1的缺乏对结肠炎的保护作用。此外,对小鼠组织病理学分析发现,对Vanin-1的抑制或敲除能显著改善小鼠结肠的病变(Berruyer C,等人Vanin-1-/-mice exhibit a glutathione mediated tissueresistance to oxidative stress.Mol.Cell Biol.2004;24:7214-7224; Berruyer C,等人Vanin-1licenses inflammatory mediator production by gut epithelial cellsand controls colitis by antagonizing peroxisome proliferator-activatedreceptorγactivity.J.Exp.Med. 2006;203:2817-2827)。
另外,Vanin-1也被认为在心血管疾病和肿瘤疾病中起调节作用。有研究证明,Vanin- 1在体外调节平滑肌细胞的活化,并在体内调节响应于颈动脉结扎的新内膜增生的发生。 VNN1基因的多态性与血压和HDL水平相关。在SF-1转基因小鼠中,Vanin-1缺失防止小鼠发展为肾上腺皮质的瘤形成,表明了Vanin-1在某些癌症中的作用。在炎症性疾病方面的研究发现,与正常个体相比,在牛皮癣的皮肤损伤中,Vanin-1高度上调。在患有儿童免疫血小板减少症(ITP)的患者的全血中,VNN1的基因表达也上调,其中VNN1的过表达与慢性ITP的进展相关。另外,在患有多种肾脏病症的患者尿液中已检测到Vanin-1 升高,所述肾脏病症包括系统性红斑狼疮、肾脏毒物(nephrotoxicant)-诱导的肾损伤和2型糖尿病(Rommelaere S,等人PPARalpha regulates the production of serum Vanin-1byliver. FEBS Lett.2013Nov 15;587(22):3742-8)。
