Abstract
Ganoderma lucidum, a medicinal mushroom with a long history in traditional Chinese medicine, is widely used for chronic diseases. Ganospirones A−G (1–7), seven pairs of undescribed spiro-meroterpenoids, were isolated from the fruiting bodies of G. lucidum. Their structures including absolute configurations were characterized by using NMR spectroscopic data, ECD computational and X-ray diffraction methods. The anti-inflammatory and anti-renal fibrosis activities of the meroterpenoids 1–7 were tested, and the results revealed that (−)-2 and (+)-2 could inhibit iNOS expression in lipopolysaccharide-induced RAW264.7 cells at 20 μM.
