8,4′-Oxyneolignane glucosides from an aqueous extract of “ban lan gen” (Isatis indigotica root) and their absolute configurations
Three pairs of glycosidic 8,4'-oxyneolignane diastereoisomers, named isatioxyneolignosides A-F (1-6), were isolated from an aqueous extract of Isatis indigotica roots. Their structures and absolute configurations were elucidated by comprehensive spectroscopic data analysis and enzyme hydrolysis. The validity of ΔδC8-C7 values to distinguish threo and erythro aryl glycerol units and Cotton effec...
متن کاملAromatic compounds from an aqueous extract of “ban lan gen” and their antiviral activities
A pair of new diphenyl glycerol ether enantiomers (-)-1 and (+)-1 and two new methyl benzamidobenzoates 2 and 3, named (-)-(R)- and (+)-(S)-isatindigotrioic acid [(-)-1 and (+)-1] and isatindigoticamides A (2) and B (3), respectively, were isolated from an aqueous decoction of the roots of Isatis indigotica (ban lan gen). Their structures were elucidated by spectroscopic data analysis including...
متن کاملIndole alkaloid sulfonic acids from an aqueous extract of Isatis indigotica roots and their antiviral activity
Six new indole alkaloid sulfonic acids (1-6), together with two analogues (7 and 8) that were previously reported as synthetic products, were isolated from an aqueous extract of the Isatis indigotica root. Their structures including the absolute configurations were determined by spectroscopic data analysis, combined with enzyme hydrolysis and comparison of experimental circular dichroism and ca...
متن کاملThree pairs of alkaloid enantiomers from the root of Isatis indigotica
Three pairs of enantiomerically pure alkaloids with diverse structure features, named isatindigoticoic acid A and epiisatindigoticoic acid A [(-)-1 and (+)-1], phaitanthrin A and epiphaitanthrin A [(-)-2 and (+)-2], and isatindopyrromizol A and epiisatindopyrromizol A [(-)-3 and (+)-3], respectively, were isolated from an aqueous extract of the roots of Isatis indigotica. Racemic and scalemic m...
متن کاملAntiviral Activity of Isatis indigotica Extract and Its Derived Indirubin against Japanese Encephalitis Virus
Isatis indigotica is widely used in Chinese Traditional Medicine for clinical treatment of virus infection, tumor, and inflammation, yet its antiviral activities remain unclear. This study probed antiviral activity of I. indigotica extract and its marker compounds against Japanese encephalitis virus (JEV). I. indigotica methanol extract, indigo, and indirubin proved less cytotoxic than other co...
