A new C(18)-ceramide congener named pecipamide (1), together with the known ergosta-4,6,8(14),22-tetraen-3-one (2), was isolated from the solid fermentations of the basidiomycetous fungus Polyporus picipes. The structure of the new metabolite was established as (2'R,2S,3R)-N-2'-hydroxyheptadecanoyl-2-amino-octadecane-1,3-diol on the basis of spectroscopic data, including 1D- and 2D- nuclear magnetic
从担子菌的固体发酵中分离出一种新的 C(18)-神经酰胺同系物,名为 Pecipamide (1),以及已知的 ergosta-4,6,8(14),22-tetraen-3-one (2)。真菌猪苓。根据光谱数据(包括一维和二维)确定了新代谢物的结构为 (2'R,2S,3R)-N-2'-hydroxyleptadecanoyl-2-amino-octadecane-1,3-diol核磁共振波谱 (NMR) 实验,以及质谱测量 (MS)。
