Oral cavity hosts an exhaustive collection of microorganisms which are known to be associated with disease such as dental caries, periodontal and deep-seated infections. Elimination of these pathogens from the site of infection remains a perplexing task, which demands the use of antibiotics. The emergence of drug resistant forms has spurred interest into identifying novel therapeutic targets against these pathogens. In this context, the present study has been designed to analyse and identify potential drug targets of the phytocompound reserpine in red complex pathogens. Computational tools were used to identify the targets, assess its functional role and virulence property. Further, the peptide epitopes present in the virulence factors were identified using BepiPred tool. The subcellular location of the virulence proteins were also elucidated using PSORTb. Reserpine was found to target vital protein transporters such as ABC transporter and efflux pumps which are known to play a crucial role in the survival of bacterial cells. Hence the present in silico study provides substantial evidence on the anti-bacterial activity of reserpine against red complex pathogens. However, in vitro studies using the compound is warranted to further confirm the efficacy of the compound.
