Time course of CBX‐addition experiment during DENV‐2 infection. a: Infected with DENV‐2, A549 cells were treated with 100 µM CBX at different time frames: starting at 1 hr before DENV‐2 infection (pre‐treatment); 0 hr concurrently with viral infection till 24 hr post‐infection (post‐treatment); from 1 hr prior to viral infection till 24 hr post‐infection (continuous‐treatment) or till 16 hr post‐infection (short‐treatment). b: The titer of progeny DENV‐2 particles was measured by TCID₅₀ assay. Data are shown as mean ± SEM of at least three independent experiments. ***P < 0.001. NS, non‐significant by t‐test (n = 3).
