Objective:To decipher the possible mechanisms of Sinomenium Acutum (SA) in treating diseases by a bioinformatics method.Methods:SA ingredients were searched according to Chinese Pharmacopoeia,Chinese Medicine Dictionary and Traditional Chinese Medicines Database (TCMD).Active compounds and target proteins of SA were acquired through the Pubchem platform.Pathway,network and function analyses of SA were performed with ingenuity pathway analysis (IPA),a bioinformatics analysis platform.Disease,biofunction-target networks were established with Cytoscape.Results:Eighteen ingredients from SA were obtained.Seven active ingredients with 31 active target proteins were acquired according to PubChem Bioassay test.By IPA analysis,277 canonical pathways belonging to 17 function categories were collected,23 kinds of diseases,21 categories bio-functions were obtained.Based on P value,calculated by IPA,the top 5 significant pathway of SA targets include phosphatidylinositol 3 kinase/Akt (PI3K/Akt) signaling,prostate cancer signaling,macrophage migration inhibitory factor (MIF) regulation of innate immunity,Guanosine-binding protein coupled receptor (GPCR) signaling,and ataxia telangiectasia mutated protein (ATM) signaling.Disease and bio-function network analysis indicated that mitogen activated protein kinase 1 (MAPK1),MAPK3,p65 nuclear factor κ B (RELA),nuclear factor of κ B inhibitor alpha (NF κ BIA),interleukin 1 β (IL-1 β),prostaglandin G/H synthase 2 (PTGS2) and tumor protein 53 (TP53) were the critical targets in various diseases treated by SA.Conclusions:In the different view of target,pathway,disease and bio-function,inflammation was found to be a central theme in many chronic conditions.SA could be used not only as an anti-inflammatory agent,but also for the treatment of cancers,neurological diseases,psychological disorders and metabolic diseases.
