Abstract
本发明涉及喹啉衍生物及其在医药上的应用,具体涉及通式(I)所示的喹啉衍生物及其在医药上的应用。本发明的化合物可治疗自身免疫疾病和与TLR7、TLR8或TLR9相关的疾病,并且可用于制备IL‑6抑制剂
Description
技术领域
本发明涉及喹啉衍生物或者其立体异构体或药物可接受的盐,及其在医药上的应用。
背景技术
Toll样受体(Toll-like receptors,TLR)是一类分子模式识别受体,广泛分布于不同的组织中,监视识别不同的病原体相关分子模式(PAMP)和损伤相关分子模式(DAMP),在先天免疫和获得性免疫中均扮演着重要的角色。
TLR属于I型跨膜蛋白,到目前为止已发现13个TLR家族成员,其中10个存在于人类中,TLR1、TLR2、TLR4、TLR5、TLR6、TLR10和TLR11位于细胞膜上,可以识别微生物的脂类、脂蛋白等物质;而TLR3、TLR7、TLR8和TLR9位于胞内囊泡结构(如溶酶体、内涵体和内质网等),识别微生物的核酸。
TLR7和TLR8在序列和功能上最相似,大量研究表明,TLR7/8的激活可以引发I型干扰素应答及多种炎症反应,在自身免疫性障碍如系统性红斑狼疮(SLE)的情况下,TLR7/8的异常持续激活导致疾病状态的恶化。因此,开发具有选择性和强效抑制活性化合物,通过拮抗TLR7/8抑制过度激活的免疫反应有望成为治疗自身免疫性疾病的新方法。
