57 The present invention discloses a compound of the formula:
where R1 is hydrogen or the group -C(R3)(R5)-R4, where R3 and R4 are the same or different and are hydrogen, C1 to C12 linear or branched alkyl, C3 to C7 cycloalkyl, C6 to C10 aryl unsubstituted or substituted with C1 to C6 linear or branched alkyl, C1 to C6 linear or branched alkoxy, nitro, amino, amino substituted with at least one C1 to C6 linear or branched alkyl or phenyl, C2 to C10 aralkyl, C4 to C8 heteroaryl wherein said heteroatom is nitrogen, phosphorous, sulfur or oxygen, and R2 is hydrogen, or taken together with Rs, forms a chemical bond, and R is a monosaccharide radical selected from the group consisting essentially of glucose, fructose, ribose, 2-deoxyribose, mannose, galactose, xylose and arabinose. The compounds prepared by the present invention are therapeutically effective adenosine receptor agonists in mammals. Thus, they are effective for treating conditions which respond to selective adenosine A2 receptor stimulation (particularly adenosine-2). Accordingly, the compounds of the present invention are useful for treating hypertension, thrombosis and atherosclerosis and for causing coronary vasodilation.
57 本发明公开了一种式化合物:
其中R1为氢或基团-C(R3)(R5)-R4,其中R3和R4相同或不同且为氢、C1至C12直链或支链烷基、C3至C7环烷基、未取代或被C1至C6直链或支链烷基取代的C6至C10芳基、C1至C6直链或支链烷氧基、硝基、氨基、被至少一个C1至C6直链或支链烷基或苯基取代的氨基、C2 至 C10 芳烷基、C4 至 C8 杂芳基,其中所述杂原子为氮、磷、硫或氧,R2 为氢,或与 Rs 结合形成化学键,R 为单糖基,选自主要由葡萄糖、果糖、核糖、2-脱氧核糖、甘露糖、半乳糖、木糖和阿拉伯糖组成的组。本发明制备的化合物是哺乳动物体内具有治疗效果的腺苷受体激动剂。因此,它们可有效治疗对选择性腺苷 A2 受体刺激(特别是腺苷-2)有反应的病症。因此,本发明的化合物可用于治疗高血压、血栓形成和动脉粥样硬化,以及引起冠状动脉血管扩张。
