group was inserted in place of the glycosidic bond of a potent and selective A3 adenosine receptor antagonist 2. The analogues were designed to induce maximum binding interaction in the binding site of the A3 adenosine receptor. However, all homologated nucleosides were devoid of binding affinity at all subtypes of adenosine receptors, indicating that free rotation through the single bond allowed the
我们合成了同源截短的 4'-硫腺苷类似物3,其中插入了一个亚甲基 (CH 2 ) 基团来代替有效和选择性的 A 3腺苷受体拮抗剂2的糖苷键。类似物被设计成在A 3腺苷受体的结合位点诱导最大的结合相互作用。然而,所有同源核苷对腺苷受体的所有亚型都缺乏结合亲和力,表明通过单键的自由旋转允许化合物采用无限数量的构象,破坏了受体识别所必需的有利结合相互作用。
