Twenty purine 2'-deoxy-2'-fluororibosides were synthesized by enzymic pentosyl transfer from 2'-deoxy-2'-fluorouridine. Each nucleoside analogue was assayed for cytotoxicity in uninfected Madin-Darby canine kidney cells and for their ability to suppress influenza A virus infections in these cells. The most potent antivirial activity was observed with analogues having an amino group in the 2-position
通过酶促戊二糖从2'-脱氧-2'-氟尿苷转移合成了20个嘌呤2'-脱氧-2'-氟核苷。分析了每种核苷类似物在未感染的Madin-Darby犬肾细胞中的细胞毒性,以及它们在这些细胞中抑制甲型流感病毒感染的能力。用嘌呤部分2-位具有氨基的类似物观察到最有效的抗病毒活性。所有2-未取代的类似物均比其2-氨基对应物效力低。此外,2-甲基,2-甲氧基或2-氟取代消除了抗病毒活性。该系列中最具细胞毒性的成员是2-氟-6-氨基类似物(IC50 = 120 microM)。2'-脱氧-2' -氟鸟嘌呤和那些由腺苷脱氨酶容易转化为它的同源物显示出最有效的抗病毒活性(IC50 = 15-23 microM)。该类似物亚组几乎没有细胞毒性,因此作为潜在的抗流感药物值得进一步研究。
