Summary: | 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)‐1
H
‐indole (
3
) and
N‐
1
‐β‐
glucopyranosyl‐3‐(2‐methoxy‐2‐oxoethyl)‐1
H
‐indole (
4
) could be detected. Compound
3
is the
N
‐glucoside of the plant‐growth regulator 1
H
‐indole‐3‐acetic acid (IAA), but, in contrast, it does not exhibit auxin‐like activity in an
Arabidopsis thaliana
tap root elongation assay. |
