ABSTRACT
A pair of new diphenyl glycerol ether enantiomers (-)-and (+)-and two new methyl benzamidobenzoatesand, named (-)-()- and (+)-()-isatindigotrioic acid [(-)-and (+)-] and isatindigoticamides A () and B (), respectively, were isolated from an aqueous decoction of the roots of(ban lan gen). Their structures were elucidated by spectroscopic data analysis including 2D NMR experiments. The absolute configurations of (-)-and (+)-were assigned based on the CD exciton chirality method. Compoundsandexhibited antiviral activities against HSV-1 with ICvalues of 4.87 and 25.87 μmol/L, respectively. Compoundwas also found active against Coxsackie virus B3 and LPS-induced NO production.
