TL;DR: A new indole alkaloid, together with four known indole alkaloids, was isolated from the 95% EtOH extract of the traditional Chinese medicinal plant Isatis indigotica as mentioned in this paper.
Abstract: A new indole alkaloid 1, together with four known indole alkaloids 2–5, was isolated from the 95% EtOH extract of the traditional Chinese medicinal plant Isatis indigotica. Alkaloids 2–5 were found in the plant for the first time. Their structures were elucidated as 3-hydroxy-3-acetonitrile-4-hydroxy-2-indolone (1), 1-methoxy-3-indoleacetonitrile (2), 3-indoleacetic acid (3), 3-indolealdehyde (4), and 1-methoxy-3indolecarbaldehyde (5) on the basis of spectroscopic data. Their anti-HSV effects in vitro were evaluated by plaque reduction assay.

Journal ArticleDOI
TL;DR: Three indole alkaloids and a new alkaloid, 5-hydroxy-3,6-oxidovoacangine, isolated from Voacanga africana were found to exhibit potent cannabinoid CB1 receptor antagonistic activity, the first example of CB1 antagonists derived from natural alkal steroids.
