usefulness of the new linker-type molecules was demonstrated by the solid-support synthesis of the potentially antivirally active 3′-deoxyadenylyl-(2′–5′)-2′-adenylic acid 2′-2-[(adenin-9-yl)methoxy]ethyl} ester (38) starting from the 2′-end with N6,N6-[2-(2-carboxyethyl)glutaryl]-9-2-[(4,4′-dimethoxytrityl)ethoxy]methyl}adenine (12).
研究了各种双官能氨基保护基团,例如邻苯二甲酰基,琥珀酰基和戊二酰基作为潜在的连接分子,用于连接到固相支持物上。戊烷1,3,5-三羧酸1,3-酐(16)具有最佳性能,并与不同糖保护的腺苷(参见20和22),胞苷(参见29)和鸟苷衍生物的氨基反应(见32),以相应的2-(2-羧乙基)戊二衍生物23,24,30,和33。潜在的抗病毒活性3'-脱氧腺苷基-(2'-5')-2'-腺苷酸2'-2-[(腺嘌呤- -9-基)甲氧基]乙基}酯(38)从所述2'-端开始ñ 6,ñ 6 - [2-(2-羧乙基)戊二酰] -9 - 2 - [(4,4'-二甲氧基三苯甲基)乙氧基]甲基}腺嘌呤(12)。
