The overexpression of NIK plays a critical role in liver inflammatory diseases. Treatment of such diseases with small-molecule NIK inhibitors is a reasonable but underexplored approach. In this paper, we reported the discovery of a potent and selective NIK inhibitor 46 (XT2). 46 inhibited the NIK kinase with an IC50 value of 9.1 nM in vitro, and it also potently suppressed NIK activities in intact
