Citrinal B, a tricyclic compound from endophytic fungus Colletotrichum capsici in our previous studies, exhibited significant inhibitory activity against 11 beta-hydroxysteroid dehydrogenase type 1 (11 beta-HSD1) in vitro and showed strong binding affinity to 11 beta-HSD1. Moreover, citrinal B treatments decreased the lipid droplet accumulation associate with the inhibition of 11 beta-HSD1 expression in differentiate induced 3T3-L1 preadipocytes. Furthermore, the molecular docking demonstrated that citrinal B coordinated in the active site of 11 beta-HSD1 is essential for the ability of diminishing the enzyme activity.
