In Silico Identifcation Of New Potential Inhibitors Of Quorum Sensing By Gram‑Positive Bacteria Through Specialized Molecular Docking, Amgad Albohy, Najla A. Obaid, Mariam Mojally, Mohammed Abou Rehab, Najd Ahmad Alkhudhir
Pharmacy
Quorum sensing is the process by which bacterial cells can communicate by producing substances to regulate viable processes such as gene expression, virulence, and bioflm formation. Gram-positive bacteria such as Staphylococcus aureus and Enterococcus faecalis have specifc enzymes (autoinducers) that control the quorum sensing system. Sortase A is a surface protein that regulates virulence and cell‒cell communication in Gram-positive bacteria. To interfere with this system and reduce virulence and cell‒cell communication, quorum sensing inhibitors are used, which are nonantibiotic substances. In this study, we aimed to use Food and Drug Administration-approved drugs (analgesics and antipsychotics) and investigate their activity using …
