An in silico Analysis of Protein Targeted by Glycyrrhizin in Common Dental Pathogens. Journal of Pharmaceutical Research International. 2020 Aug; 32(15): 170-1782456-91192231-2919http://imsear.searo.who.int/handle/123456789/215884Glycyrrhizin is a phytocompound which is derived from Glycyrrhiza glabra. It is used in treating the upper respiratory tract disease like cough, bronchitis, laryngitis, sore throat, etc. It has various medicinal uses in rheumatism, peptic ulcers, asthma, allergies, and inflammation. Glycyrrhizin has been reported to possess antibacterial, antiviral, antioxidant, anti inflammatory properties. In view of the above facts, the present in silicostudy was designed to demonstrate the molecular mechanism underlying the antimicrobial activity of glycyrrhizin against common dental pathogens such as Streptococcus mutans, Porphyromonas gingivalis, Treponema denticola, Enterococcus faecalisandTannerella forsythia.The STITCH tool was used to identify the drug-protein interaction. The functional class of the protein was deduced using VICMPred, followed by the identification of epitopes on the virulence factors using BepiPred. Further, the subcellular location of the virulence factors were also studied using PSORTb software. The computational analysis performed identified several virulence factors viz., short chain dehydrogenase/reductase family oxidoreductase of Treponema denticola and D-mannonate oxidoreductase of Tannerella forsythiawhich were found to interact with glycyrrhizin. Interestingly, phosphopyruvate hydratase was found to be the protein present in all the five genera was shown to interact with glycyrrhizin. Thus the present study reveals the target proteins on the dental pathogens which were shown to interact with glycyrrhizin. Furthermore,experimental validation of the resultsare warranted to provide substantial details on the anti-microbial activity of glycyrrhizin against common dental pathogensGlycyrrhizinin silico analysisSTITCHVICMPredvirulenceJournal ArticleIndiaDepartment of Microbiology, Saveetha Dental College, SaveethaInstitute of Medical and Technical Sciences (SIMATS), Saveetha University, 162, Poonamallee High Road ,Chennai 600077, Tamil Nadu, India.Department of Microbiology, Saveetha Dental College, SaveethaInstitute of Medical and Technical Sciences (SIMATS), Saveetha University, 162, Poonamallee High Road ,Chennai 600077, Tamil Nadu, India.Biomedical Research Unit and Laboratory Animal Centre -Dental Research Cell, Saveetha Dental College, SaveethaInstitute of Medical and Technical Sciences (SIMATS), Saveetha University, Chennai 600077,India.
