autoimmune disorders such as psoriasis, arthritis, and lupus. In our search for small molecule antagonists of TLR7/9, 7f was identified as possessing excellent on-target potency for human TLR7/9 as well as for TLR8, with selectivity against other representative TLR family members. Good pharmacokinetic properties and a relatively balanced potency against TLR7 and TLR9 in mouse systems (systems which lack
                                    Toll 样受体 (TLR) 家族是先天免疫系统进化上保守的组成部分,负责早期检测外来或内源性威胁信号。在自身免疫的背景下,无意中将自身基序识别为外来的会促进疾病的发生或传播。TLR7 和 TLR9 的过度激活被认为是导致自身免疫性疾病(如
银屑病、关节炎和狼疮)的因素。在我们的TLR7 / 9,小分子拮抗剂搜索1408米被鉴定为对人 TLR7/9 和 TLR8 具有出色的靶向效力,对其他代表性 TLR 家族成员具有选择性。在小鼠系统(缺乏功能性 TLR8 的系统)中,良好的药代动力学特性和相对平衡的 TLR7 和 TLR9 效力使其成为一种出色的体内工具化合物,并且在自身免疫性疾病的临床前模型中证明了口服给药的功效。
