Cell-Based Assay: The ability of representative disclosed to block influenza infection was assessed in a cell-based assay using A549 human epithelial cells (ATCC CCL-185). Briefly, a spatial infection model for testing drug efficacy and influenza replication was adapted from Lam et al. (Biotechnol Bioeng. (2005) 90(7):793-804). A549 cells were plated on Lab-Tek two well Permanox slides (Nalge Nunc International, Rochester, N.Y.) and allowed to become nearly confluent during an overnight incubation. Culture media used in these experiments was as described above, i.e. in DMEM supplemented with 5% fetal bovine serum, 100 U/ml penicillin, and 100 ug/ml streptomycin. Following overnight incubation, the cells were then washed three times with PBS, and 2 ml of a binary mixture of 2% agar and 2xMEM (with 100 U/ml penicillin, 100 ug/ml streptomycin, 2 mM L-glutamine, and 1xMEM vitamin solution (e.g. Gibco Cat. No. 111120 for 100x solution) was added to the cells.
