for activity. The new nucleosides were 9-(6-deoxy-beta-D-glucopyranosyl)adenine (2), 9-(6-deoxy-beta-D-allopyranosyl)adenine (3), 9-(6-deoxy-alpha-L-talopyranosyl)adenine (4), 9-alpha-D-rhamnopyranosyladenine (5), and 9-(6-deoxy-alpha-L-idopyranosyl)adenine (6). In addition, 9-(6-deoxy-alpha-L-sorbofuranosyl)adenine (7) was isolated from the same preparation as 6. None of the new nucleosides 2-7 had
9-β-D-富勒索糖基腺嘌呤(1)对培养物中生长的L1210细胞的抗白血病活性较弱。通过标准程序合成了几种新的6'-脱氧己吡喃糖基腺嘌呤核苷,并对其活性进行了测定。新的核苷是9-(6-脱氧-β-D-吡喃葡萄糖基)腺嘌呤(2),9-(6-脱氧-β-D-戊吡喃糖基)腺嘌呤(3),9-(6-脱氧-α-L -talopyranosyl)腺嘌呤(4),9-α-D-鼠李糖吡喃糖基腺嘌呤(5)和9-(6-脱氧-α-L-idopyranosyl)腺嘌呤(6)。另外,从与6相同的制剂中分离出9-(6-脱氧-α-L-山梨糖醛酸基)腺嘌呤(7)。新的核苷2-7都没有抗培养中的L1210细胞的活性。还测试了许多与结构相关的其他已知核苷的活性。其中一种9-α-L-阿拉伯吡喃型腺嘌呤腺苷具有活性,但明显弱于1。
