The present invention relates to small molecule 4-(piperazin-1-yl)quinazolin-2-amino compounds with formula (I) useful for inhibiting signalling by certain toll-like receptors (TLRs), especially TLR9. Toll-like receptors (TLRs) are members of the larger family of evolutionarily conserved pattern recognition receptors which are critical first line of defense for self-nonself discrimination by the host immune response. Aberrant TLR9 activation is implicated in autoreactive inflammation in different autoimmune diseases. The invention depicts compounds with formula (I), composition and methods can be used in a number of clinical applications, including as pharmaceutical agents and methods for treating conditions involving unwanted immune activity due to TLR9 activation.
本发明涉及小分子 4-(哌嗪-1-基)喹唑啉-2-氨基化合物,其式(I)有助于抑制某些类毒素受体(TLRs),特别是 TLR9 的信号传导。类毒素受体(TLRs)是进化保守的模式识别受体大家族的成员,是宿主免疫反应识别自我和非自我的关键第一道防线。TLR9的异常激活与不同自身免疫性疾病中的自身反应性炎症有关。本发明描述的式(I)化合物、组合物和方法可用于多种临床应用,包括作为药物制剂和方法用于治疗因TLR9活化而导致的不需要的免疫活动。
