The calculated results show that the binding affinity between Myricetin and MMP-7 is higher than that between Pyrogallic acid and MMP-7 when they bind to MMP-7, thus Myricetin is more potent on MMP-7 than Pyrogallic acid. This is in agreement with the inhibitory activity order from experiments.

研究结果表明，在与MMP-7结合时，杨梅黄酮比焦性没食子酸具有更高的亲合性，因此杨梅黄酮对MMP-7有更好的效能，这与实验测得的活性顺序相符。
