Some novel substituted pyrazole and pyrazolo[3,4-d]pyrimidine derivatives 2, 4, 8, and 9 were synthesized. Also, some acyclic S-nucleosides of pyrazolo[3,4-d]pyrimidine derivatives 10-13 were prepared via reaction of pyrazolo[3,4-d]pyrimidine-4(3H)-thione derivative 9 with some acyclic sugars. Moreover, the N-nucleoside derivative 14 was prepared via reaction of compound 8 with glucosamine hydrochloride
合成了一些新颖的取代吡唑和吡唑并[3,4-d]嘧啶衍生物2、4、8和9。同样,通过吡唑并[3,4-d]嘧啶-4(3H)-硫酮衍生物9与一些无环糖的反应制备了吡唑并[3,4-d]嘧啶衍生物10-13的一些无环S-核苷。此外,通过化合物8与氨基葡萄糖盐酸盐的反应制备N-核苷衍生物14。对某些精选新产品的抗病毒评估表明,它们对甲型肝炎病毒(HAV)和1型单纯疱疹病毒(HSV-1)具有良好的抗病毒活性。
