• First report of novel FAAH inhibition was recorded for heterocyclic carbohydrazide derivatives. • Compound 26 exhibited high selectivity towards FAAH when comparing with CES2 and MAGL. • Molecular docking analysis was performed to delineate several key binding interactions. • Compound 26 displayed obviously anti-neuroinflammation activity against LPS-induced BV2 cell injury. Fatty acid amide hydrolase (FAAH) is a promising target for the development of drugs to treat pain, inflammation, and other central nervous system disorders. Herein, a series of novel heterocyclic carbohydrazide derivatives were firstly designed by the classic scaffold-hopping strategy. Then, multi-steps synthesis and human FAAH enzyme inhibiting activity assays were conducted. Among them, compound 26 showed strong inhibition against human FAAH with IC 50 of 2.8 μM. Corresponding docking studies revealed that the acyl hydrazide group of compound 26 well-occupied the acyl-chain binding pocket. It also exhibited high selectivity towards FAAH when comparing with CES2 and MAGL. Additionally, compound 26 effectively suppressed the LPS-induced neuroinflammation of microglial cells (BV2) via the reduction of interleukin-1β and tumor necrosis factor-α. Our results provided significative lead compounds for the further discovery of novel selective and safe FAAH inhibitors with potent anti-neuroinflammation activity. [ABSTRACT FROM AUTHOR]
