  • Title: Synthesis and evaluation of a new series of substituted acyl(thio)urea and thiadiazolo [2,3-a] pyrimidine derivatives as potent inhibitors of influenza virus neuraminidase.
    Author: Sun C, Zhang X, Huang H, Zhou P.
    Journal: Bioorg Med Chem; 2006 Dec 15; 14(24):8574-81. PubMed ID: 16979342.
    Abstract:
    A series of substituted acyl(thio)urea and 2H-1,2,4-thiadiazolo [2,3-a] pyrimidine derivatives were prepared and both of their cell culture and enzymatic activity toward influenza virus were tested. Their in vitro neuraminidase inhibitory activities were in good agreement with the corresponding activities in cultured cells and they were evaluated as potent neuraminidase inhibitors. Of the analogues that demonstrated IC(50)s<0.1microM, 16 and 60 were further investigated as candidates with the most potential for future development. The molecular docking work of the representative compound was described to provide more insight into their mechanism of action and further rationalize the observations of this new series herein, which represents a novel class of highly potent and selective inhibitors of influenza virus.
