基于分子对接技术探讨“附子无干姜不热”的作用机制

目的:利用分子对接技术,探讨"附子无干姜不热"的作用机制。方法:利用相关数据库和Autodock 4.2软件,将附子、干姜中乌头碱、次乌头碱、新乌头碱、6-姜酚、8-姜酚、10-姜酚和6-姜烯酚等7种主要成分与线粒体钙离子单向转运蛋白(mitochondrial calcium uniporter,MCU)进行分子对接。结果:在温度保持在298.15 K的条件下,乌头碱、次乌头碱、新乌头碱、6-姜酚、8-姜酚、10-姜酚和6-姜烯酚与MCU(4XSJ)的抑制常数分别为180.40、258.88、430.37、574.20、130.57、629.48和167.00 mmol/L,与MCU(4XT...

Summary:目的:利用分子对接技术,探讨"附子无干姜不热"的作用机制。方法:利用相关数据库和Autodock 4.2软件,将附子、干姜中乌头碱、次乌头碱、新乌头碱、6-姜酚、8-姜酚、10-姜酚和6-姜烯酚等7种主要成分与线粒体钙离子单向转运蛋白(mitochondrial calcium uniporter,MCU)进行分子对接。结果:在温度保持在298.15 K的条件下,乌头碱、次乌头碱、新乌头碱、6-姜酚、8-姜酚、10-姜酚和6-姜烯酚与MCU(4XSJ)的抑制常数分别为180.40、258.88、430.37、574.20、130.57、629.48和167.00 mmol/L,与MCU(4XTB)的抑制常数分别为199.380 00μmol/L,2.760 00、0.218 37、1.370 00、1.780 00、3.660 00 mmol/L和0.217 14μmol/L。结论:"附子无干姜不热"的作用机制可能与干姜中6-姜酚、6-姜烯酚和10-姜酚竞争性抑制乌头碱与Pro1130氨基酸残基和Asp148氨基酸残基结合,减弱乌头碱对MCU(4XTB)以及MCU(4XSJ)的抑制作用有关。
