Abstract

This study aimed to provide an inclusive in silico investigation for the identification of novel drug targets that can be exploited to develop drug candidates for treating oral infections caused by S. sputigena. By coupling subtractive genomics with an in silico drug discovery approach, we identified dTDP-4-dehydrorhamnose 3,5-epimerase (UniProt ID: C9LUR0), UTP-glucose-1-phosphate uridyltransferase (UniProt ID: C9LRH1), and imidazole glycerol phosphate synthase (UniProt ID: C9LTU7) as three unique proteins crucial for the S. sputigena life cycle with no substantial similarity to human proteins. These potential drug targets served as the starting point for screening bioactive phytochemicals (1090 compounds) from the Indian Medicinal Plants, Phytochemistry and Therapeutics (IMPPAT) database. Among the screened natural products, cubebin (IMPHY001912) showed a higher affinity for two of the three selected targets, as evidenced by molecular docking and molecular dynamics studies. Given its favorable drug-like profile and possible multitargeting behavior, cubebin could be further exploited as an antibacterial agent for treating S. sputigena-mediated oral infections. It is worth nothing that cubebin could be the active ingredient of appropriate formulations such as mouthwash and/or toothpaste to treat S. sputigena-induced periodontitis, with the advantage of limiting the adverse effects that could affect the use of current drugs.
