Phenoxybenzenes and phenoxypyridines were prepared and tested for the effect of substituents on antipicornavirus activity. The most active compound, 2-(3,4-dichlorophenoxy)-5-nitrobenzonitrile (8), demonstrated broad-spectrum antipicornavirus activity. Compound 8 and several analogues each given orally prior to and during infection protected mice against an otherwise lethal challenge with coxsackievirus A21.
Die Chlorierung der Titelverbindung bei verschiedenen Temperaturen in Abwesenheit und Gegenwart von Chlorbenzol als Lösungsmittel und Phosphortrichlorid führt zu den in der l. Mitt. beschriebenen Monochlorcyclohexancarbonsäuren [wie z.B. (II)‐(IV), vergleiche vorstehendes Referat] und zum Teil höher chlorierten Säuren.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
