We employed molecular docking, molecular dynamics simulations, and computational mutagenesis to evaluate the binding of halogenated phenazine compounds (C1 to C7, HP, and HP-14) to AgrA. Binding free energy analysis was performed to assess the affinity of these compounds for the AgrA-DNA complex.

The binding-free energy analysis revealed that all compounds enhance binding affinity compared to the Apo form of AgrA, which has a <i>Δ</i>G_bind of -80.75 kcal/mol.

Molecular dynamics simulations demonstrated that these compounds bind at the hydrophobic cleft of AgrA, disrupting essential salt bridge interactions between His174-Glu163 and His174-Glu226. This disruption led to structural conformational changes and reduced DNA binding affinity, aligning with experimental findings on biofilm inhibition. The halogenated phenazine compounds effectively inhibit biofilm formation by targeting AgrA, disrupting its DNA-binding function.
