The synthesis of the 3′-fluoro-derivatives of 5-amino-1-(β-D-ribofuranosyl)imidazole-4- carboxamide (AICA-riboside) and the isomeric 4-amino-1(β-D-ribofuranosyl)imidazole-5- carboxamide (iso-AICA-riboside) are described. Structures were confirmed by elemental analysis, UV and 1H NMR spectroscopy. The anti-viral and anti-cancer activities of these imidazole nucleosides were tested.
本文介绍了3'-氟衍生物的合成,包括5-氨基-1-(β-D-核糖呋喃)咪唑-4-甲酰胺(AICA-核苷)和同分异构体4-氨基-1(β-D-核糖呋喃)咪唑-5-甲酰胺(iso-AICA-核苷)。通过元素分析、紫外线和1H核磁共振光谱确定了它们的结构。对这些咪唑核苷的抗病毒和抗癌活性进行了测试。
