Abstract
本发明涉及一种式(I)化合物,其中R1至R2如说明书和权利要求书中所定义。所述式(I)化合物可用作药物。
Description
本发明涉及可用于哺乳动物的治疗和/或预防的有机化合物,特别是涉及调节cGAS活性的化合物。
本发明特别涉及一种式(I)化合物,
其中
R1为烷基异噁唑基、烷基三唑基、烷基咪唑基、烷基异噻唑基或噁唑基;并且
R2为烷基-二氧代(dioxido)-7,8-二氢-5H-噻喃并[4,3-d]嘧啶基、烷氧基-5,6,7,8-四氢喹唑啉基、苯基-5,6,7,8-四氢喹唑啉基、(烷氧基苯基)-1-氧代-1,2-二氢异喹啉基、二烷基苯基氨基羰基吡啶基、烷氧基吡嗪基、吡啶基、萘基、烷氧基吡啶基、烷氧基哒嗪基、氧代-吡啶基、(N-烷基)氧代-吡啶基、氧代-茚满基、卤代烷基苯基、烷氧基羰基苯基、(烷氧基羰基)烷基噻吩基或(烷氧基羰基)噻吩基;
或其药学上可接受的盐、立体异构体或互变异构体。
细胞因子负责先天性免疫应答的调节,且促炎症性细胞因子的失调与严重的全身性炎症和自身免疫性疾病相关联,其中许多迄今为止仍缺乏有效的疗法。
脊椎动物具有先天性和适应性免疫系统,其作为抵御病原体和其他挑战的保护。先天性免疫系统为一种进化的旧系统,其在脊椎动物之外也存在。与适应性免疫系统不同,它不需要启动或训练,而是作为一般的物理屏障(例如皮肤)或通过特定模式的检测来工作。触发先天性免疫系统的一种普遍模式为细胞溶质双链DNA的检测,其导致I型干扰素应答。细胞溶质dsDNA的来源可能来自细菌或病毒感染,但也可能来自积累的自身DNA。
细胞溶质酶环状GMP-AMP合酶(cGAS)为细胞溶质双链DNA的传感器。dsDNA的结合导致通过ATP和GTP的酶促连接产生环状二核苷酸2,3-cGAMP。2,3-cGAMP充当第二信使并与位于内质网中的干扰素基因刺激物(STING)结合。在2,3-cGAMP结合后,STING移位至核周高尔基体,在那里它与TANK结合激酶1(TBK1)相关联并募集和磷酸化干扰素应答因子3(IRF3)。最终,这导致产生I型干扰素(I IFN)、其他细胞因子,如IL-6、TNFα、IL1β和趋化因子(对于宿主防御入侵病原体的重要因素)。然而,I型IFN和其他促炎症性细胞因子的不当或慢性产生与严重的全身性炎症和自身免疫性疾病相关联。例如,IFN信号传导参与SLE、皮肤型皮肤病(皮肌炎和皮肤型狼疮)、间质性肺纤维化、干燥综合征和I型糖尿病(G.Trinchieri,J Exp Med.2010 207(10):2053-63)。其他促炎症性细胞因子诸如TNFα和IL1β在炎症性肠病、NASH、幼年型炎症性关节炎、强直性脊柱炎和痛风中发挥重要作用。
cGAS/STING的慢性激活导致严重的全身性炎症。关于它在临床炎症中作用的证据来自单基因疾病。核酸修饰酶(如Trex1、RNaseH2和SAMHD1)缺乏的患者患有Aicardi-Goutieres综合征(AGS)。在用作AGS模型的Trex1缺陷型小鼠中支持cGAS/STING的参与。
因此,抑制疾病介导细胞因子上游的cGAS途径为治疗患者免受多种自身免疫性疾病的新策略。适应症可能包括连接至IFN信号传导的那些适应症或由TNFα和IL1β驱动的那些适应症。
迄今为止,许多由先天性免疫系统失调引起的疾病都缺乏有效的疗法。
本发明的化合物与cGAS结合并调节其活性。
式(I)化合物特别适用于治疗或预防例如系统性红斑狼疮(SLE)、皮肤型皮肤病如皮肌炎或皮肤型狼疮、间质性肺纤维化、干燥综合征、I型糖尿病、炎症性肠病、非酒精性脂肪性肝炎(NASH)、幼年型炎症性关节炎、强直性脊柱炎、痛风或Aicardi-Goutieres综合征(AGS)。
