中文摘要：
采用电喷雾质谱法研究了防己诺林碱与双链核酸及G-四链体的相互作用. 结果表明, 防己诺林碱可选择性地与G-四链体结合. 利用串联质谱技术对防己诺林碱与核酸的结合模式进行了研究, 结果表明, 防己诺林碱可能通过末端堆积作用与G-四链体结合, 而通过插入作用与双链核酸结合. 结合模式的差异导致防己诺林碱选择性地与G-四链体结合.
英文摘要：
Electrospray ionization mass spectrometry （ESI-MS） was used to investigate the interaction of fangchinoline with G-quadruplex and duplex DNA. The results showed that fangchinoline selectively bound to G-quadruplex DNA. Upon MS/MS experiments, complexes of fangchinoline and G-quadruplex DNA underwent the loss of fangchinoline, suggesting an end-stacking binding mode, while complexes of fangchinoline and duplex DNA underwent the loss of fangchinoline, suggesting the intercalated binding mode.
