Biological properties of novel antistaphylococcal quinoline-indole agents.

The antibacterial properties of novel quinoline-indole (QI) agents were examined. QI agents demonstrated potent bactericidal activities against Staphylococcus aureus, killing by lytic and nonlytic mechanisms. S.

Potent in vitro methicillin-resistant Staphylococcus aureus activity of 2-(1H-indol-3-yl)tetrahydroquinoline derivatives.

Novel antibacterials agents, 2-(1H-indol-3-yl)tetrahydroquinolines, were prepared using hetero Diels-Alder chemistry and found to be effective in vitro against methicillin-resistant Staphylococcus aureus (MRSA). A structure-activity relationship (SAR) study was conducted to determine the important features of this series and to increase the potency of these compounds. Compounds were prepared that had minimum inhibitory concentrations (MIC's) < 1.
