This invention pertains to nucleoside analogs that have antiviral activity and improved metabolic stability, compositions comprising them, and methods of antiviral treatment employing them. More particularly, this invention pertains to imidazo[1,2-a]pyridine C-nucleosides, as exemplified by compounds such as imidazo[l,2-a]pyridine C5-nucleosides and imidazo[1,2-a]pyridine C3-nucleosides, and may be represented by formula (I), wherein exactly one of Q3 and Q5 is a sugar-like moiety; exactly one of Q3 and Q5 is —H; and Q2, Q6, Q7 and Q8 are independently imidazo[1,2-a]pyridine substituents, such as —H, —F, —Cl, —Br and —I.
这项发明涉及具有抗病毒活性和改善代谢稳定性的核苷类似物,包括它们的组合物,以及利用它们的抗病毒治疗方法。更具体地,这项发明涉及咪唑[1,2-a]吡啶C-核苷,例如咪唑[1,2-a]吡啶C5-核苷和咪唑[1,2-a]吡啶C3-核苷等化合物,可以用公式(I)表示,其中Q3和Q5中的一个恰好是类似于糖的基团;Q3和Q5中的一个恰好是—H;Q2、Q6、Q7和Q8独立地是咪唑[1,2-a]吡啶取代基,例如—H、—F、—Cl、—Br和—I。
