[Anti-inflammatory mechanism research of flavonoid compounds in Dalbergiae Odoriferae Lignum by module-based network analysis].
Dalbergiae Odoriferae Lignum as a traditional Chinese medicine (TCM) has been widely used for promoting blood circulation and removing blood stasis. Flavonoid compounds are main chemical constituents of Dalbergiae Odoriferae Lignum, which exert anti-inflammatory property. However, the underlying anti-inflammatory mechanisms of flavonoid compounds are incompletely understood. It has been reported that isoliquiritigenin, liquiritigenin, naringenin and butein possess anti-inflammatory property. The purpose of this study is to illuminate the anti-inflammatory mechanism of flavonoid compounds based on the protein interaction network (PIN) analysis on molecular network level. 130 targets of the main medicinal ingredients of flavonoid compounds were gained though database retrieval. A protein interaction network of flavonoid compounds was constructed with 589 nodes and 216 interactions. By a graph theoretic clustering algorithm Molecular Complex Detection (MCODE), 26 modules were identified and analyzed by Gene ontology (GO) enrichment. Two modules were associated with anti-inflammatory actions. The most interesting finding of this study was that the anti-inflammatory effect of flavonoid compounds may be partly attributable to inhibite FOS, PTGS2 expression, inhibite of IL-1beta release, and block the MAPK pathway and toll-like receptor pathway.
