Chloroquine inhibits Zika Virus infection in different cellular models

Here we show that chloroquine exhibits antiviral activity against ZIKV in VERO, human brain microvascular endothelial, and neural stem cells. We demonstrated in vitro that chloroquine reduces the number of ZIKV-infected cells, virus production and cell death promoted by ZIKV infection without cytotoxic effects. Our results suggest that chloroquine is a promising candidate for ZIKV clinical trials, since it is already approved for clinical use and can be safely administered to pregnant woman.
