摘要:
A series of new N,N'-disubstituted thioureas were prepared and evaluated in vitro for their activity against myxoviruses. Compound N-[4-(3-propoxy-1H-1,2,4-triazol-1-yl)phenyl]-Ar-(2-pyrazinyl)thiourea 5d exhibited specific activity against respiratory syncytial virus in HeLa cells. Compounds N-(1-adamantanyl)-N'-[4-(3-ethoxy-1H-1,2,4-triazol-1-yl)phenyl]thiourea 5g and N-(1-adamantanyl)-N'-[4-(3-propoxy-1H-1,2,4-triazol-1-yl)phenyl]thiourea 5h proved active against influenza A in Madin-Darby canine kidney (MDCK) cells and respiratory syncytial virus in HeLa cells.
