A new nucleoside and two new pyrrole alkaloid derivatives from Cordyceps militaris.

A new nucleoside, a new natural product nucleoside, and two new pyrrole alkaloids derivatives with eight known compounds were isolated from the fruiting body of Cordyceps militaris. The structures of the new compounds were elucidated through extensive analysis of spectroscopic data including 1D and 2D NMR, HRESIMS, IR and UV. All the isolated compounds were detected for their bioactivities against LPS-induced NO production in RAW 264.7 cells. Unfortunately, all the isolates have shown no obvious activity.
