Advances in Piperazine-based Compounds for Antimicrobial Drug Development: Design, SAR, and Therapeutic Potential

Piperazine derivatives have shown enhanced antibacterial activity through specific structural modifications.

• Incorporating electron-withdrawing groups such as Cl, Br, and NO2 into piperazine derivatives is associated with improved antibacterial effectiveness.
• Conversely, the addition of electron-donating groups and certain ring substitutions, like pyridine and furan, often leads to reduced potency.
• Molecular docking studies indicate that piperazine derivatives effectively bind to microbial enzymes and proteins, supporting their proposed mechanism of action.
• The integration of computational methods and medicinal chemistry strategies has enabled the design of more potent piperazine derivatives with better drug absorption and distribution.
• Piperazine-based antimicrobials may be particularly effective against infections caused by multidrug-resistant pathogens.
