Determination of the antiviral activity of a naturally occurring sulfated xylomannan under various experimental conditions
The effects of different experimental conditions on the antiviral activity of the sulphated xylomannan F6, isolated from the red seaweed Nothogenia fastigiata, against the replication of herpes simplex virus type 1 and 2 (HSV-1 and HSV-2) were studied. The compound was equally effective against seve...
