Infectious virus yields were determined in A549 cells infected with adenovirus and treated with 0 or up to 100 μM WR1065. Cells in six-well plates were infected with a given species of adenovirus. After 1 hr adsorption, cells were replenished with minimum essential medium containing 0 or up to 100 μM WR1065. At 7 days postinfection, infected cells were frozen and infectious virus yields in freeze-thawed preparations were titered by plaque assay.
Infected with 103 PFUs, adsorption for 1 hr.
Infected with 104 PFUs, adsorption for 1 hr.
Two additional experiments using 100 μM WR1065 yielded similar results.
P < 0.05 (χ2 test), compared with untreated infected A549 cells.
P < 0.001 (χ2 test), compared with untreated infected A549 cells.
