“…In particular, the antiviral effect of polysaccharides against the herpes simplex virus (HSV) has been reported (Arad, Ginsberg, & Huleihel, 2006;Damonte, Matulewicz, & Cerezo, 2004;Karmakar, Pujol, Damonte, Tuhin Ghosh, & Ray, 2010;Luescher-Mattli, 2003;Pujol, Carlucci, Matulewicz, & Damonte, 2007) and some of these polysaccharides are currently undergoing either preclinical or clinical evaluation (Kleymann, 2005;McReynolds & Garvey-Hague, 2007). Unlike the widely used acyclovir (ACV)-related nucleoside analogues, which all targeted against viral DNA synthesis, polysaccharides interfere with the attachment of virus to host cell surface by binding to viral envelope glycoprotein (Damonte et al, 2004;Duarte et al, 2001;Neyts et al, 1992;Witvrouw & De Clercq, 1997).…”
