metabolism. We report herein the discovery of lead chemical series of NIK inhibitors that were identified through a scaffold-hopping strategy using structure-based design. Electronic and steric properties of lead compounds were modified to address glutathione conjugation and amide hydrolysis. These highly potent compounds exhibited selective inhibition of LTβR-dependent p52 translocation and transcription of
NF-κB诱导激酶(NIK)是位于多个TNF受体家族成员(包括BAFF)下游的非规范NF-κB通路中枢的蛋白激酶,与B细胞存活和成熟,树突状细胞活化,继发性淋巴器官有关发育和骨骼代谢。我们在此报告了使用基于结构的设计通过支架跳跃策略确定的NIK
抑制剂的主要
化学系列的发现。修饰了先导化合物的电子和空间特性,以解决
谷胱甘肽共轭和酰胺
水解的问题。这些高效的化合物表现出对LTβR依赖性p52易位和NF-κB2相关
基因转录的选择性抑制。化合物4f 已显示出在种间具有良好的药代动力学特征,并在体外抑制BAFF诱导的B细胞存活并在体内减少脾边缘区B细胞。
