Carbon Dioxide → Deoxynojirimycin

Cells and viruses. BVDV-free MDBK cells (CCL 22) were obtained from the American Type Culture Collection and propagated in DMEM/F12 essential medium supplemented with penicillin (500 U/ml), streptomycin (500 U/ml), and 10% heat inactivated horse serum (Invitrogen). Cells were maintained in a humidified incubator at 37° C. with 5% CO2. BVDV (NADL strain). For infections, virus inoculum was added in complete medium and adsorbed for 1 hour at 37° C., the inoculum was then removed, the cells washed once with medium and fresh medium containing compounds added. Virus stocks were prepared by freeze-thawing the infected cells and culture supernatant three times followed by centrifugation at 1,000 g for 5 min. Stock titers were determined, and stocks were aliquoted and stored at −80° C. WNV was obtained from a cDNA clone of a human 2002 isolate from Texas; virus obtained from BHK cells electroporated with the in vitro synthesized RNA from this cDNA clone was passaged in Vero cells before use in antiviral assays. Dengue virus (DV) serotype 2 was a New Guinea C virus that had been passaged 28 times in suckling mouse brain, twice in Vero cells, and once in C6/36 mosquito cells.
