NIK plays a crucial role in the noncanonical NF-κB signaling pathway associated with diverse inflammatory and autoimmune diseases. Our study presents compound 54, a novel NIK inhibitor, designed through a structure-based scaffold-hopping approach from the previously identified B022. Compound 54 demonstrates remarkable selectivity and potency against NIK both in vitro and in vivo, effectively suppressing
NIK 在与多种炎症和自身免疫性疾病相关的非经典 NF-κB 信号通路中发挥着至关重要的作用。我们的研究提出了化合物54 ,一种新型 NIK 抑制剂,通过基于结构的支架跳跃方法从先前鉴定的 B022 中设计出来。化合物54在体外和体内均表现出显着的针对 NIK 的选择性和效力,可有效抑制促炎细胞因子和一氧化氮的产生。在小鼠模型中,化合物54可以预防 LPS 诱导的系统性脓毒症,减少 AST、ALT 和 AKP 肝损伤标志物。此外,它还可以减轻败血症引起的肺和肾损伤。从机制上讲,化合物54通过靶向 NIK 来阻断非经典 NF-κB 信号通路,从而阻止 p100 到 p52 的加工。这项工作揭示了一类新型 NIK 抑制剂,具有治疗脓毒症的巨大潜力。
