Entrectinib inhibits NLRP3 inflammasome and inflammatory diseases by directly targeting NEK7.

ABSTRACT: Excessive inflammation caused by abnormal activation of the NLRP3 inflammasome contributes to the pathogenesis of multiple human diseases, but clinical drugs targeting the NLRP3 inflammasome are still not available. In this study, we identify entrectinib (ENB), a US Food and Drug Administration (FDA)-approved anti-cancer agent, as a target inhibitor of the NLRP3 inflammasome to treat related diseases. ENB specifically blocks NLRP3 without affecting activation of other inflammasomes. Furthermore, we demonstrate that ENB directly binds to arginine 121 (R121) of NEK7 and blocks the interaction between NEK7 and NLRP3, thereby inhibiting inflammasome assembly and activation. In vivo studies show that ENB has a significant ameliorative effect on mouse models of NLRP3 inflammasome-related disease
