Treating staphylococcal biofilm-associated infections is challenging. Based on the findings that compound 2 targeting the HK domain of Staphylococcus epidermidis YycG has bactericidal and antibiofilm activities against staphylococci, six newly synthesized derivatives were evaluated for their antibacterial activities. The six derivatives of compound 2 inhibited autophosphorylation of recombinant YycG' and the IC50 values ranged from 24.2 to 71.2 μM. The derivatives displayed bactericidal activity against planktonic S. epidermidis or Staphylococcus aureus strains in the MIC range of 1.5-3.1 μM. All the derivatives had antibiofilm activities against the 6- and 24-h biofilms of S. epidermidis. Compared to the prototype compound 2, they had less cytotoxicity for Vero cells and less hemolytic activity for human erythrocytes. The derivatives showed antibacterial activities against clinical methicillin-resistant staphylococcal isolates. The structural modification of YycG inhibitors will assist the discovery of novel agents to eliminate biofilm infections and multidrug-resistant staphylococcal infections.
