Abstract:

Several compounds extracted from spices and herbs exhibit antiviral effects in vitro, suggesting potential pharmacological uses. Curcumin, a component of turmeric, has been used as a food additive and herbal supplement due to its potential medicinal properties. Previously, curcumin exhibited antiviral properties against several viruses, including dengue virus and hepatitis Cvirus, among others. Here, we describe the antiviral effect of curcumin on Zika and chikungunya viruses, two mosquito-borne outbreak viruses. Both viruses responded to treatment of cells with up to 5 μM curumin without impacting cellular viability. We observed that direct treatment of virus withcurcumin reduced infectivity of virus in a dose- and time-dependent manner for these enveloped viruses, as well as vesicular stomatitis virus. In contrast, we found no change in infectivity for Coxsackievirus B3, a non-enveloped virus. Derivatives of curcumin also exhibited antiviral activity against enveloped viruses. Further examination revealed that curcumin interfered with the binding of the enveloped viruses to cells in a dose-dependent manner, though the integrity of the viral RNA was maintained. Together, these results expand the family of viruses sensitive to curcumin and provide a mechanism of action for curcumin's effect on these enveloped viruses.
