FMDV belongs to the Picornaviridae and has the potential to cause devastating epidemics in livestock. The 50% and 90% effective concentrations (EC50 and EC90) for inhibition of the FMDV-induced cytopathic effect (CPE) formation were 6.4+/-3.8 and 10.8+/-5.4 microM. Comparable EC50 values for inhibition of viral RNA synthesis were observed. Treatment of FMDV-infected BHK-21 cells with 77 microM 2'-C-MetCyt resulted in a (1.6-3.2)x10(3)-fold reduction of infectious virus yield. Time-of-drug addition experiments suggest that 2'-C-MetCyt interacts with viral replication at a time point that coincides with the onset of intracellular viral RNA synthesis. In contrast to emergency vaccination, a potent and selective antiviral agent may provide almost immediate (prophylactic/therapeutic) protection against infection and thus constitute an important alternative/supplementary option to contain outbreaks such as those caused by FMDV.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/17055073?dopt=Abstract</style></custom1></record></records></xml>
