A series of 3,9-dihydro-9-oxo-5H-imidazo[1,2-A]purine nucleosides (tricylic nucleosides) were synthesized from 9-[4-α-(hydroxymethyl)cyclopent-2-ene-1-α-yl]guanine (CBV) 5, (−)-β-D-(2R,4R)-1,3-dioxolane-guanosine (DXG) 6, 3′-azido-3′-deoxy-guanosine (AZG) 7, and 2′-C-methylguanosine 8. Their in vitro activity against HIV and HCV was evaluated and correlated to their ability to degrade to their purine
以9-[4-α-(羟甲基)环戊-2-烯-1为原料合成了一系列3,9-dihydro-9-oxo-5 H - imidazo [1,2- A ]嘌呤核苷(三环核苷) -α-基]鸟嘌呤 (CBV) 5 , (-)-β-D-(2 R ,4 R )-1,3-二氧戊环-鸟苷 (DXG) 6 , 3'-叠氮基-3'-脱氧-鸟苷(AZG) 7和 2'- C-甲基鸟苷8。他们对 HIV 和 HCV 的体外活性进行了评估,并与它们降解为嘌呤对应物的能力相关联。
