Nine multifarious new meroterpenoids, cochlearols E-M (1-9), along with seven known meroterpenoids 10-16, were isolated from the fruiting bodies of Ganoderma cochlear. Racemic 1, 6-8, 10 and 13 were separated by chiral HPLC. The structures were elucidated based on detailed spectroscopic analyses (HRESIMS, 1D/2D-NMR) and calculated electronic circular dichroism (ECD). Their biological activities against renal fibrosis were evaluated by using rat normal and diseased renal interstitial fibroblast cells (NRK49F). The results show that compounds 7a, 7b, and 10a exhibit potent proliferation inhibition in TGF-β1-induced NRK-49F cells.
