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
制备了一系列取代的酰基(硫)脲和2H-1,2,4-噻二唑[2,3-a]嘧啶衍生物,并测试了它们的细胞培养和对流感病毒的酶活性。它们的体外神经氨酸酶抑制活性与培养细胞中的相应活性高度吻合,并且被评价为有效的神经氨酸酶抑制剂。在显示IC(50)s <0.1microM的类似物中,有16和60被进一步研究,认为它们具有未来发展的最大潜力。描述了代表性化合物的分子对接工作,以提供对其作用机理的更多见解,并进一步使本文中该新系列的观察合理化,该新系列代表了新型的高效和选择性的流感病毒抑制剂。
