Five novel sesquiterpene glycosides, namely, cosmosporasides A-E (1-5), were isolated from the ethyl acetate extract of the fermented broth of Cosmospora joca. The structures of 1-5 were elucidated on the basis of spectroscopic data analyses, monosaccharide composition analyses, and monosaccharide chirality analyses. The relative configuration of the sesquiterpene moiety of 3-5 was determined by J-based configuration analyses and supported by NOESY assignments. The inhibitory effects of 1-5 on the nitric oxide (NO) production in lipopolysaccharide (LPS)-activated murine macrophage RAW264.7 cells were evaluated; all except 3 inhibited NO production at 100 μM. 4 was the most potent, with an average maximum inhibition and a median inhibitory concentration value of 71.70 ± 1.23% and 65.98 ± 0.53 μM, respectively.
