Figure 2. 25HC Broadly Inhibits Flaviviruses Infection.
(A and B) Vero cells were pretreated with EtOH or indicated dose of 25HC for 8 hr, followed by ZIKV infection (GZ01/2016 strain, MOI 0.1). The titer of ZIKV in the supernatant was quantified by (A) plaque assay and (B) qRT-PCR.
(C–F) Vero cells were pretreated with indicated amount of 25HC for 8 hr and then infected with (C) ZIKV GZ01/2016 strain, (D) DENV, (E) YFV, and (F) WNV at MOI 0.1. Viral RNA copies in cell lysates were quantified by qRT-PCR. IC50 of 25HC to ZIKV, DENV, YFV, and WNV were calculated and indicated. All data are shown as mean ± SEM from three independent experiments. **p ≤ 0.01, unpaired Student’s t test. See also Figure S4.
