Aim Licoricidin has multiple pharmacological activities. The present study was designed to investigate the permeability and pharmacokinetic behavior of licoricidin using in vitro models. MATERIAL AND METHODS First, human liver microsomes and recombinant human supersomes were used to investigate the interactions between metabolic enzymes and licoricidin. In addition, rat, minipig, rabbit, dog, monkey, and human liver microsomes were used to determine metabolic differences among species. The parallel artificial membrane permeability assay (PAMPA) was used to explore licoricidin permeability behavior. KEY FINDINGS At 100 μM, licoricidin strongly inhibited CYP2C9, CYP2C19, CYP3A4, UGT1A3, UGT1A6, UGT1A7, UGT1A8, UGT1A9, UGT2B4, UGT2B7, UGT2B15, and UGT2B17. Licoricidin metabolism exhibited considerable differences among species; dog, pig, and rat liver microsomes showed higher metabolic capacity than the other species. Seven licoricidin metabolites were identified by liquid chromatography-tandem mass spectrometry, and hydration and hydroxylation were the major metabolic pathways. The PAMPA permeability of licoricidin was moderate at both pH 4.0 and 7.4. SIGNIFICANCE The present study will support further pharmacological or toxicological research on licoricidin.
