New cytokine production inhibitors, CJ-14, 877 (I) and CJ-14, 897 (II), were isolated from the fermentation broth of a basidiomycete, Marasmiellus sp. CL21624. Their structures were determined to be methyl-(7R, 8S)-5-(7, 8-dihydroxypropyl) pyridine-2-carboxylate and methyl (7R, 8S)-5-(8-acetoxy-7-hydroxypropyl) pyridme-2-carboxylate, respectively, by spectroscopic analyses. These compounds showed inhibitory activities for ...
