Malonate ethers and phosphonate derivatives of 2-deoxyribose and 2-deoxy-2-fluoroarabinose have been synthesized, for the first time, as stable analogues of 2-deoxy-α-d-ribose-1-phosphate (1). In almost all the cases, the α-anomers have been obtained as the major isomers. The NMR conformational analysis performed indicate a similar conformational equilibria for the natural phosphate 1 and the here described
首次合成了2-脱氧核糖和2-脱氧-2-氟阿拉伯糖的丙二酸酯醚和膦酸酯衍生物,作为2-脱氧-α-d-核糖-1-磷酸的稳定类似物(1)。在几乎所有情况下,都已获得了α-端基异构体作为主要异构体。进行的NMR构象分析表明天然磷酸酯1和本文所述类似物的构象平衡相似,除了糖基膦酸酯3α。在250μM下,没有一种化合物能抑制纯化的大肠杆菌胸苷磷酸化酶。同样,当施用于完整的CEM细胞时,在次黄嘌呤和肌苷代谢酶(包括嘌呤核苷磷酸化酶)中也没有观察到抑制作用。
