we discovered a series of novel benzodithiazines-dioxides with both antiviral and anticancer activities. In order to design compounds with distinct antiviral properties, we prepared new compounds with modifications on the imidazole and pyrimidine rings. Herein, we present the synthesis and antiviral activity of 8-chloro-2,3-dihydroimidazo[1,2-b][1,4,2]benzodithiazine 5,5-dioxides (22, 23, 30, and 31)
以前,我们发现了一系列具有抗病毒和抗癌活性的新型二苯并噻嗪类二氧化物。为了设计具有独特抗病毒特性的化合物,我们制备了在咪唑和嘧啶环上经过修饰的新化合物。在这里,我们介绍了8-氯-2,3-二氢咪唑并[1,2-b] [1,4,2]苯并噻二嗪5,5-二氧化物(22、23、30和31)的合成和抗病毒活性,以及9-氯-2,3,4-三氢嘧啶基[1,2-b] [1,4,2]苯并噻二嗪6,6-二氧化物(14、24、25和27)。我们成功地鉴定出具有显着抗HIV-1活性(EC(50)= 0.09microM)的先导化合物。这些化合物显示出最小的细胞毒性,因此适用于抗病毒开发。
