Announcing a new review article publication for Acta Materia Medica<\/em> journal. \u00a0Bile salt hydrolases (BSHs) play crucial roles in the deconjugation of conjugated bile acids and therefore are key targets for modulating bile acid metabolism.<\/p>\n

This authors of this article aimed to identify efficacious BSH inhibitors from a natural compound library and to characterize their inhibitory mechanisms. The inhibitory potential of more than 100 natural compounds against BSH produced by\u00a0Lactobacillus salivarius<\/em>\u00a0(lsBSH) was assayed, and several chalcones with strong or moderate lsBSH inhibitory activity were identified.<\/p>\n

Of all tested chalcones, licochalcone C and isobavachalcone showed the most potent lsBSH inhibitory activity (IC50<\/sub>\u00a0< 1 \u03bcM). Inhibition kinetic analyses demonstrated that both licochalcone C and isobavachalcone reversibly inhibited lsBSH-catalyzed CA-AMCA hydrolysis\u00a0via<\/em>\u00a0a mixed manner. Docking simulations suggested that they bind lsBSH at two distinct sites mainly\u00a0via<\/em>\u00a0hydrogen bonding and hydrophobic interactions. Additionally, licochalcone C and isobavachalcone were found to inhibit various BSHs and decrease the total BSH activity in mouse feces, thus suggesting that these agents are broad-spectrum BSH inhibitors.<\/p>\n

The findings reveal that licochalcone C and isobavachalcone are naturally occurring inhibitors of BSH, which may serve as promising lead compounds in the development of more efficacious BSH inhibitors for modulating bile acid metabolism.<\/p>\n
