INTRODUCTION: Methicillin-resistant Staphylococcus aureus (MRSA), known for its resistance to multiple antibiotics, has emerged as a major global health concern. It facilitates biofilm formation under stressful conditions by catalyzing the synthesis of alarmones (p)ppGpp and ppGpp. These alarmones on accumulation lead to biofilm formation and cause resistance towards antibiotics.
METHODS: This condition has prompted the exploration of various novel approaches and methodologies to combat MRSA infections. Among these, peptide therapeutics stand out as a promising nextgeneration treatment option. In this study, ninety antimicrobial peptides were sourced from the antimicrobial peptide database and the other sixty-one peptide sequences were designed using the Pepdraw server. These peptide sequences were screened out using different in-silico tools. The proteinpeptide molecular interaction was studied using a molecular docking and molecular dynamic simulation technique.
RESULTS AND DISCUSSION: Out of 151 peptide sequences, Pantocin wh-1 emerged as the most promising drug candidate. Both molecular interaction studies and molecular dynamics simulations demonstrated positive results.
CONCLUSION: Peptide therapeutics is a novel approach researchers are presently exploring as it provides prompt significant results and promotes a new insight towards dealing with conditions like MDR. Pantocin wh-1 is a peptide drug currently listed as an accessible anti-tuberculosis peptide, and this study suggests the repurposing of this drug as a viable treatment option for MRSA infections.
