1b. Compounds 1b, 6b and 7b exhibited no selective antiviral activity against several DNA and RNA viruses. Compound 1b had weak antibacterial activity (minimum inhibitory concentration approximately 25-50 micrograms/ml) and was cytotoxic to several tumor cell lines (L1210, Molt 4, CEM) at a concentration of about 5 microM. This antitumor cell activity may be attributed to inhibition of protein biosynthesis
开发了合成2'-脱氧-2'-氟嘌呤霉素(1b)的方法。lyxo-epoxide(4)的开环或3'-O-甲磺酸酯(5)被叠氮化物离子的亲核取代提供了两个叠氮基核苷6a和7a。使主要产物(7a)与二乙基氨基三氟化硫(DAST)反应,得到2'-氟核苷(8),其通过氢化转化为3'-氨基核苷(9)。用常规方法将化合物9与氨基酸缩合,然后用酸脱保护,得到1b。化合物1b,6b和7b对几种DNA和RNA病毒没有选择性的抗病毒活性。化合物1b具有弱的抗菌活性(最低抑制浓度约为25-50微克/ ml),并且对几种肿瘤细胞系(L1210,Molt 4,CEM)的浓度约为5 microM。这种抗肿瘤细胞活性可以归因于蛋白质生物合成的抑制。
