Title: Ginseng, the natural effectual antiviral: Protective effects of Korean Red Ginseng against viral infection Document date: 2015_9_16
ID: u800148j_11
Snippet: In an attempt to investigate the effects of ginsenosides on rhinovirus infection, Song et al [26] examined the antiviral activities of protopanaxatriol (PT)-type ginsenosides (Re, Rf, and Rg2), and protopanaxadiol (PD)-type ginsenosides (Rb1, Rb2, Rc, and Rd). The results showed that PT-type ginsenosides protected HeLa cells from human rhinovirus 3 (HRV3)-induced cell death as determined by sulforhodamine B staining of viable cells and morphologi.....
Document: In an attempt to investigate the effects of ginsenosides on rhinovirus infection, Song et al [26] examined the antiviral activities of protopanaxatriol (PT)-type ginsenosides (Re, Rf, and Rg2), and protopanaxadiol (PD)-type ginsenosides (Rb1, Rb2, Rc, and Rd). The results showed that PT-type ginsenosides protected HeLa cells from human rhinovirus 3 (HRV3)-induced cell death as determined by sulforhodamine B staining of viable cells and morphological assessment [26] . However, PD-type ginsenosides did not show any protective effects and even stimulated the HRV3-induced cell death significantly, implying a structure-dependent effect of ginsenosides on HRV3. The selective antiviral activities of panaxatriol-type ginsenosides were also found in the case of coxsackievirus, as described below. Future studies are needed to elucidate the relationship between the antiviral activities and structural differences among panaxadiol-and panaxatriol-type ginsenosides.
