A review of pyridine and pyrimidine derivatives as anti-MRSA agents

Methicillin-resistant Staphylococcus aureus (MRSA) is a gram-positive strain whose resistance against existing antibiotics is a major concern for the researchers across the globe. Gram-positive infections, particularly methicillin-resistant Staphylococcus aureus spreading among S. aureus isolates, observed to increase exponentially from 29% in 2009 to 47% in 2014. Literature reviews revealed about 13-74% of worldwide S. aureus strains are Methicillin-resistant. In this article, we have summarized the mechanism of bacterium resistance, molecular targets to treat MRSA, and the activity of reported pyridine and pyrimidine derivatives against methicillin-resistant Staphylococcus aureus. The data collected for this study from online peer reviewed research articles and Molecular-docking study of reported anti-MRSA agents performed by using Maestro Module of Schrodinger software. Results of in silico studies showed that some pyridine derivatives having better binding interactions than standard anti-MRSA agents. Molecular docking studies of reported pyridine derivatives resulted in excellent hits for the development of novel anti- MRSA agents. Overall, this study will be immense importance for researchers working in design and development of target based anti-MRSA agents.
