In vitro antiviral activity of new oxazoline derivatives as potent poliovirus inhibitors
The final stages of polio eradication are proving more difficult than the early phases and the development of effective drugs and treatments is considered a priority, thus the research is ongoing. A screening of our in-house chemical library against poliovirus Sabin strains led to identification of 5 and 6 as hits active at submicromolar concentration. Derivatives of these compounds were synthesized as a preliminary structure-activity relationship study. Among them, 7 and 11 were highly active against poliovirus Sabin 1, 2 and 3.
