Lanostane Triterpenoids from the Fruiting Bodies of Fomes officinalis and Their Anti-Inflammatory Activities

In the current study, further chemical investigation of the fruiting bodies of Fomes officinalis led to isolate seven new 24-methyl-lanostane triterpenoids, named officimalonic acids I−O (1–7). Their structures were elucidated based on the analysis of spectroscopic data (HR-MS, 1D and 2D NMR, UV, IR...

Sumario:In the current study, further chemical investigation of the fruiting bodies of Fomes officinalis led to isolate seven new 24-methyl-lanostane triterpenoids, named officimalonic acids I−O (1–7). Their structures were elucidated based on the analysis of spectroscopic data (HR-MS, 1D and 2D NMR, UV, IR). Compounds 1−3 possessed an unusual C-23 spirostructure moiety, while compounds 4−7 had 23,26-lactone unit. Anti-inflammatory assay revealed that compounds 3 and 5 exhibited significant inhibitory activities against NO production in LPS-induced RAW 264.7 cells and cyclooxygenase (COX-2).
