Biodivers.}, doi = {10.1002/cbdv.200890062}, volume = {5}, abstract = {Two new N ‐glucosylated indole alkaloids were isolated from fruiting bodies of the basidiomycete Cortinarius brunneus (Pers .) Fr . The structures were elucidated by means of the spectroscopic data. Additionally, the very recently reported compounds N‐ 1‐β‐ glucopyranosyl‐3‐(carboxymethyl)‐1H ‐indole (3 ) and N‐ 1‐β‐ glucopyranosyl‐3‐(2‐methoxy‐2‐oxoethyl)‐1H ‐indole (4 ) could be detected. Compound 3 is the N ‐glucoside of the plant‐growth regulator 1H ‐indole‐3‐acetic acid (IAA), but, in contrast, it does not exhibit auxin‐like activity in an Arabidopsis thaliana tap root elongation assay.} }
