摘要: |
Lingzhifuran A (1) and lingzhilactones D-F (2-4), four new phenolic meroterpenoids were isolated from the fruiting bodies of Ganoderma lucidum. Their structures were identified by spectroscopic data. Chiral HPLC analysis indicates the racemic nature of 2-4. Chiral separation followed by X-ray diffraction analysis discloses the absolute configuration of (-)-2. Compounds 1 and 2 could selectively inhibit TGF-beta 1-induced Smad3 phosphorylation in rat renal tubular epithelial cells, representing novel scaffolds of selective Smad3 activation inhibitors. Total synthesis accompanied by in vivo rodent experiments reveals antifibrotic activities of 1 against kidney fibrosis. Finally, a plausible biosynthetic pathway for 1 was proposed. |
