Ivermectin Inhibits Zika Virus Replication in Vitro But Does Not Prevent Zika Virus Infection in Rhesus Macaques (Macaca mulatta).

ABSTRACT: Zika virus (ZIKV) outbreaks occur sporadically in tropical and subtropical regions. At present, there are no licensed vaccines or specific treatments available for ZIKV. Ivermectin is approved for use in humans as an antiparasitic drug. In this study, we conducted in vitro cell culture and in vivo experiments in rhesus macaque hosts and Aedes aegypti vectors to investigate the potential of ivermectin as an inhibitor of ZIKV infection. In LLC-MK2 mammalian cells, ivermectin inhibited ZIKV growth in vitro with 50% inhibitory concentration (IC50) values in the ranges of 7.4-21.3 µM and 4.0-11.6 µM for African and Asian genotypes, respectively. In C6/36 mosquito cells, ivermectin inhibited ZIKV growth in vitro with IC50 values in the ranges of 10.1-17.4 µM and 8.0-15.6 µM for the African and A
