A method was developed for the synthesis of dihydroberberine nitroaryl derivatives on the basis of dihydroberberine reactions with aromatic electrophiles (picryl chloride, 4-chloro-7-nitrobenzofurazan, 4-chloro-5,7-dinitrobenzofurazan, and 7-chloro-4,6-dinitrobenzofuroxan). The obtained 13-substituted dihydroberberine derivatives represent structures with significant intramolecular charge transfer
开发了一种基于二氢小ber碱与芳香族亲电试剂(氯化苄酯,4-氯-7-硝基苯并呋喃,4-氯-5,7-二硝基苯并呋喃和7-氯-4,6)的二氢小ber碱硝基芳基衍生物的合成方法-二硝基苯并呋喃聚糖)。所获得的13-取代的二氢小ber碱衍生物代表具有显着的分子内电荷转移的结构,并且根据分子对接分析的结果,可以有效地与端粒DNA片段的G-四链体结合。
