Adenophostins A and B are naturally occurring glyconucleotides that interact potently with receptors for D-myo-inositol 1,4,5-trisphosphate, an important second messenger molecule in most cell types. Here we describe the design and synthesis of glucopyranoside-based analogues of adenophostin A lacking the adenine component. The key synthetic strategy involves glycosylation of selectively protected
腺苷A和B是天然存在的糖核苷酸,可与D-肌醇1,4,5-三磷酸酯(大多数细胞类型中重要的第二信使分子)的受体有效相互作用。在这里,我们描述了缺乏腺嘌呤成分的基于腺苷A的吡喃葡萄糖苷类似物的设计和合成。关键的合成策略涉及使用由2,6-二-O-苄基-D-吡喃葡萄糖衍生物合成的糖基供体,对甲基β-D-核呋喃糖苷或1,4-脱水赤藓糖醇衍生的选择性保护的醇进行糖基化。偶联产物的进一步精制和脱保护得到两个三磷酸酯类似物。甲基3-O-α-D-吡喃葡萄糖基-β-D-呋喃呋喃糖苷2,3',4'-三磷酸(“ ribophostin”)和(3'S,4'R)-3'-羟基四氢呋喃-4'-基α- D-吡喃葡萄糖苷3,4,3'-三磷酸酯(“呋喃酮”)。进一步修饰呋喃核黄素的路线,得到(3'S,4'R)-3'-羟基四氢呋喃-4'-基α-D-吡喃葡萄糖苷3'-磷酸3,4-双硫代磷酸酯,这是第一个含硫代磷酸酯的腺苷类似物。
