Previous studies have indicated that curcumin, a polyphenol extracted from the plant Curcuma longa, has demonstrated antiviral properties against a variety of viruses. After establishing the maximum non-cytotoxic concentrations of curcumin on Vero cells, HSV-1 and HSV-2 virions were treated with varying concentrations of curcumin. The effect on infectivity was determined by antiviral assays, using WST-1, plaque assays, adsorption and penetration assays. Treating HSV-1 and HSV-2 viruses with curcumin, at a concentration of 30 μM, reduces the production of infectious HSV-1 and HSV-2 virions in cultured Vero cells by interfering with the adsorption process. These results support the potential of curcumin to be used as a therapeutic agent to reduce the transmission of HSV-1 and HSV-2.展开更多
