at N-8 of the 8-azapurine ring system. Structure proofs utilized UV and 1H and 13C NMR data. Compounds 6b-e,g and 7b-f were evaluated in the H.Ep.-2 cell culture screen, and compounds 6c-e and 7d were evaluated in the P388 mouse leukemia screen. Adenosine deaminase data are also presented for some compounds.
描述了2-氟-8-氮杂腺苷(6e)和2-氨基-8-氮杂腺苷(6d)的合成。9H-2,6-双(甲硫基)-8-氮杂嘌呤(4)与2,3,5-三-O-乙酰基-D-呋喃呋喃糖基氯(5)的缩合产生6a(9-beta-D)的混合物-呋喃核糖基)和7a(8-β-D-呋喃核糖基)。标准的官能团操作,包括引入氟的改进的Schiemann反应,可从主要异构体6a制备6d和6e。通过一系列类似的反应,次要组分7a转化为7d和7e,核糖环连接在8-氮杂嘌呤环系统的N-8上。结构证明利用了UV以及1H和13C NMR数据。在H.Ep.-2细胞培养筛选中评估化合物6b-e,g和7b-f,在P388小鼠白血病筛选中评估化合物6c-e和7d。
