Zika virus (ZIKV) infection in utero might lead to microcephaly and other congenital defects. Since no specific therapy is available thus far, there an urgent need for the discovery of agents capable inhibiting its viral replication deleterious effects. Chloroquine widely used as antimalarial drug, anti-inflammatory agent, it also shows antiviral activity against several viruses. Here we show that chloroquine exhibits ZIKV Vero cells, human brain microvascular endothelial neural stem mouse...
