Abstract Title:
Antiviral effect of compounds derived from Angelica archangelica L. on Herpes simplex virus-1 and Coxsackievirus B3 infections.
Abstract:
The dichloromethane extract from fruits of Angelica archangelica L. was separated by the modern high-performance countercurrent chromatography (HPCCC). The extract and five pure compounds: xanthotoxin, bergapten, imperatorin, phellopterin and isoimperatorin, and the mixture of imperatorin and phellopterin, have been studied as the potential antiviral agents against Herpes simplex virus type l and Coxsackievirus B3. The cytotoxicity was measured using the MTT method. Compounds were tested for the in vitro antiviral activity using the cytopathic effect (CPE) inhibitory assay and by the virus titre reduction assay. Real-time PCR was used to quantify the relative inhibition of the HSV-1 replication. The results indicate that the highest activity was demonstrated by the extract, imperatorin, phellopterin and the mixture of imperatorin and phellopterin, reducing the HSV-1 replication by 5.61 log, 4.7 log, 3.01 log and 3.73 log, respectively. The influence of isolated compounds on the CVB3 replication was not significant. Only the extract caused the decrease in the titre of virus in relationto the virus control. Our results show that coumarins of A. archangelica L. might be a potential candidate for the development of the alternative natural anti- HSV-1 compound. Moreover, the presence of isopentenyloxy moiety at C-8 position significantly improves their activity.
