Abstract:
Qigui Tongfeng tablet (QLTFT) is a traditional Chinese medicine with good effect for treating gout. Here, network pharmacology method and molecular similarity analysis were utilized to study the effective substance basis and molecular mechanism of the QLTFT on the gout. The similarity to the medicinal compounds is reflected in the Tanimoto coefficient that gives the structural similarity of two compounds. Operationally, similar modifiers were described as pairs of concepts with a similarity score of 0. 500. The results of the molecular similarity analysis suggested that the flavonoids in QLTFT could be new leads for gout. Furthermore, complex biological systems may be represented and analyzed as computable networks. Two important properties of a network were degree and betweenness. Nodes with high degree or high betweenness may play important roles in the overall composition of a network. And the results of network analysis showed that dongbeinine, verticinone-N-oxide, verticine N-oxide, peimine, peiminine, isobaimonidine, dongbeirine, peimisine and simi-arenol which with high degree acted on xanthine dehydrogenase/oxidase, matrix metalloproteinase-9, an arachidonate 5-lipoxygenase-activating protein, tyrosine-protein kinase and etc. Inhibition of these targets can prevent the formation of uric acid, reduce inflammation by uric acid and regulate the body's immune response. Thus, these compounds may be the main effective substance basis. The research results not only reveals its molecular mechanism, but also provide a theoretical basis for the quality control of drugs and clinical application.
