The aminoglycoside and aminoglycotide N⁴-(2,3,5-tri-O-acetyl-β-D-ribofuranosyl)pyrimido|4,5-d]pyrimidine-4,8-diamine and N⁴-(5-O-phosphono-β-D-ribofuranosyl)pyrimido[4,5-d]pyrimidine-4,8-diamine exhibit antiviral activity as well as cytotoxic activity against the L1210 and mammary 16/C tumor cell lines.
An improved method for their production involves the production of a sylilated intermediate and reaction of the intermediate with tetra-O-acetyl-β-D-ribofuranose in the presence of the specific catalyst trimethylsilyltrifluoromethanesulfonate.
氨基糖苷和氨基糖苷酸 N⁴-(2,3,5-三-O-乙酰基-β-D-呋喃核糖基)嘧啶|4,5-d]嘧啶-4,8-二胺和 N⁴-(5-O-膦酰-β-D-呋喃核糖基)嘧啶[4、5-d]嘧啶-4,8-二胺对 L1210 和乳腺 16/C 肿瘤细胞系具有抗病毒活性和细胞毒性活性。
一种改进的生产方法是先生产出一种苯胺化中间体,然后在特定催化剂三甲基硅基三氟甲磺酸酯的作用下,将该中间体与四-O-乙酰基-β-D-呋喃核糖反应。
