Synthesis of novel benzo[h]quinolines: wound healing, antibacterial, DNA binding and in vitro antioxidant activity.

We have characterized a new class of 2-mercapto/2-selenobenzo[h]quinoline-3-carbaldehyde (3/4). Antibacterial potential of these compounds against a wide range of gram-positive and gram-negative bacteria was studied. The selenium containing compound 4 showed significant inhibition zone on Staphylococcus aureus (22.
