摘要:

以水溶性磷酸盐柱[6]芳烃(WP6P)为主体, 天然药物甘松新酮(ND)为客体, 采用饱和溶液法构筑了一种新的ND/WP6P主客体包合物. 通过紫外光谱滴定法研究了主客体之间的络合行为, 结果表明, ND和WP6P以摩尔比1∶1形成主客体包合物, 其络合常数为5.160×104 L/mol. 利用红外吸收光谱、 X射线粉末衍射、 热重分析(TG)、 示差扫描量热分析(DSC)和扫描电子显微镜对形成的包合物进行了表征. 通过一维和二维核磁共振氢谱及分子对接模拟等方法进一步验证了ND与WP6P之间形成主客体包合物的包合模式. 本文为水溶性柱芳烃在天然药物方面的应用提供了理论参考.

Abstract:

Using water-soluble phosphate salt pillar[6]arene(WP6P) as the host and the natural drug nardosinone(ND) as the guest, the saturated solution method was used to construct a new the host-guest inclusion compound of ND/WP6P. The complexation behavior between the host and guest was studied by UV spectrome- tric titration. The results showed that ND and WP6P formed inclusion compound at a molar ratio of 1∶1, and the complex constant was 5.160×104 L/mol. Infrared spectroscopy(IR), X-ray powder diffraction(XRD), thermos gravimetry(TG), differential thermal analysis(DSC) and scanning electron microscope(SEM) were used to characterize the ND/WP6P inclusion compound. The possible inclusion mode of between ND and WP6P was further verified by nuclear magnetic resonance(1H NMR, 2D NMR) and molecular docking simulation. This study provides a theoretical reference for the application of water-soluble pillar[6]arene in natural medicine.
