本研究开发了三种新的6-(芳硫基)尿嘧啶衍生物,即6-(苯硫基)嘧啶-2,4(1 H ,3 H )-二酮( 1 )、C 10 H 8 N 2 O 2 S;6-( p -tolylthio)pyrimidine-2,4(1 H ,3 H )-dione ( 2 ), C 11 H 10 N 2 O 2 S;和 6-(3,5-二甲基苯硫基)嘧啶-2,4(1 H ,3 H )-二酮 ( 3 ), C 12 H 12 N 2 O 2S,已经合成。这些化合物的单晶结构揭示了一个不变的分子带,其中包含交替的R 2 2 (8) 合成子,由1和3 中的N-H···O 氢键形成。这种交替的氢键模式在2 中消失了;相反,会生成一个新的合成子。晶格能计算表明,甲基取代衍生物(2和3)比化合物1具有更高的稳定能。. 静电势图揭示了羰基氧接受倾向的差异。Hirshfeld 表面和 2D 指纹图分析表明,主要的分子间相互作用来自1

Abstract A series of 6-(Arylthio)uracils have been prepared via condensation of 6-chlorouracil or 5-ethyl-6-chlorouracil with the corresponding thiophenol derivatives in pyridine or ethanolic potassium hydroxide. The synthesized compounds were tested for their antiviral activity. Some of the 5-ethyl-6-(arylthio)uracil derivatives 10a-g showed moderate activities against hepatitis B Virus (HBV) and
