Some new 6‐amino‐1,3‐dimethyl‐5‐(substituted methylidene)aminouracils were synthesized. Most of them were cyclized with triethyl orthoformate as a one‐carbon source to afford 1,3‐dimethyl‐6‐substituted pteridine derivatives. Certain uracils gave xanthine instead of the expected pteridine derivatives upon using another one‐carbon source such as triethyl orthoacetate or triethyl orthobenzoate. The nucleic
合成了一些新的6-氨基-1,3-二甲基-5-(取代亚甲基)氨基尿嘧啶。它们中的大多数与原甲酸三乙酯作为单碳源环化,得到 1,3-二甲基-6-取代的蝶啶衍生物。某些尿嘧啶在使用另一种单碳源(如原乙酸三乙酯或原苯甲酸三乙酯)时产生黄嘌呤而不是预期的蝶啶衍生物。核酸结合试验表明,与仅对 DNA 具有亲和力的阿昔洛韦相反,一些新化合物显示出高亲和力、螯合和核酸片段化,无论是 DNA 还是 RNA。这些新型化合物的抗病毒活性表明,化合物 2e 和 2f 分别将 Vero 细胞培养物中小反刍兽疫病毒 (PPRV) 的细胞致病性降低了 60% 和 50%。
