A new alkaloid from Chaetomium globosum

球毛壳霉中一个新的生物碱类化合物（英文）

A new alkaloid, methyl 6-（isoprenyl）-lH-indole-3-carboxylate （1）, was isolated from the solid culture broth of fungus Chaetomium globosum, together with five known compounds, including N-acetyl-L-tryptophan （2）, xylariol B （3）, 5-（methoxymethyl）- 1H-pyrrole-2-carbaldehyde （4）, ergosterol （5） and ergosta-4,6,8（14）,22-tetraen-3-one （6）. Their chemical structures were elucidated by spectroscopic data （UV, IR, HRESIMS, and NMR）. In addition, it is the first report of compounds 2 and 3 from the fungus Chaetomium globosum.
