以鸟苷(1)为原料, 与乙酸酐经过糖环羟基保护反应, 得到2',3',5'-三-O-乙酰基鸟苷(2); 2与对甲苯磺酰氯反应, 得到9-(2',3',5'-三-O-乙酰基-β-D-呋喃核糖)-2-氨基-6-对甲苯磺酰氧基嘌呤(3); 3与亚硝酸异戊酯和二乙基二硫醚反应, 得到9-(2',3',5'-三-O-乙酰基-β-D-呋喃核糖)-6-对甲苯磺酰氧基-2-乙硫基嘌呤(4); 4经过胺解和脱糖环羟基保护反应得到10个未见报道的6-烷氨基-2-乙硫基嘌呤核苷化合物(5). 化合物结构经1H NMR、13C NMR、IR和HRMS进行了表征, 并对它们进行了抗血小板聚集活性测试, 结果表明对抗血小板聚集显示一定的活性.

Guanosine (1) as the starting material, reacted with acetic anhydride to obtain 2',3',5'-tri-O-acetyl-guanosine (2), which reacted with TsCl to obtain 2-amino-6-tosyl-9-(2',3',5'-tri-O-acetyl-β-D-ribofuranosyl)purine (3). Compound 3 was diazotized with isoamyl nitrite and then reacted with dialkyl disulfides to afford 2-ethylthio-6-tosyl-9-(2',3',5'-tri-O-acetyl-β-D-ribofuranosyl)purine (4). Finally, compounds 5 were acquired by aminolysis and deprotection of 4. Ten new compounds were synthesized and all compounds were characterized with 1H NMR, 13C NMR, IR and HRMS. Meanwhile, their antiplatelet aggregation rate was measured. The results show that these compounds have a certain antiplatelet aggregation activity.
