Abstract
A number of new N-arylaminomethyl-1,3,4-oxadiazole derivatives 2, 3a,b, and 9-12a,b were prepared. Sugar (5-N-arylaminomethyl-1,3,4-oxadiazol-2-yl) hydrazones 4-6a,b were synthesized by the reaction of the hydrazino derivatives 3a,b with the corresponding monosaccharides. The novel acyclo-C-nucleosides 7, 8a,b were prepared by heterocyclization of the sugar hydrazones 4, 5a,b with acetic anhydride. A number of the synthesized compounds were tested for their antiviral activity against herpes simplex virus type-1 (HSV-1) and hepatitis-A virus (HAV, MBBcell culture-adapted strain). The results revealed that the sugar hydrazones 6a,b showed higher antiviral activity compared to the other hydrazones and their acetylated derivatives.
