We have prepared 4-nitrobenzamide-adenine conjugates (8, 13 and 14) linked with versatile spacer such as triethylene glycol (TEG), aminocaproic acid and ethyl chains which were eventually reduced to obtain the corresponding 4-aminobenzamide-adenine conjugates (1–3) in good yields. These conjugates bear a nucleobase for DNA recognition or self-assembly through base-pair complementarity, a biocompatible linker for interfacing with biological system, and a p-aminobenzamide moiety for pharmacological applications. The use of hydrophilic or lipophilic linkers may tune the dispersibility of these conjugates in different solvents, as well as impart different properties. In the preliminary experiments the versatility and application of these linkers has been tested for functionalization of SWCNTs.
我们制备了 4-硝基苯甲酰胺-腺嘌呤共轭物(8、13 和 14),这些共轭物通过三乙二醇(TEG)、氨基己酸和乙基链等多功能间隔物连接,最终以良好的收率还原出相应的 4-氨基苯甲酰胺-腺嘌呤共轭物(1-3)。这些共轭物含有通过碱基对互补实现 DNA 识别或自组装的核碱基、与生物系统连接的生物相容性连接体以及用于药理应用的对氨基苯甲酰胺分子。使用亲水或亲油连接体可以调节这些共轭物在不同溶剂中的分散性,并赋予其不同的特性。在初步实验中,我们测试了这些连接体在 SWCNT 功能化方面的多功能性和应用。
