An Efficient, Microwave-Assisted, One-Pot Synthesis of Dioxolano Quinoline/benzo[h]quinolines as Potent Antibacterial Agents
摘要:
Quinolines/benzo[h]quinolines are associated with a broad spectrum of biological activities. In view of this, 3-(1,3-dioxolan-2-yl)quinoline/benzo[h]quinoline-2-thiol/selenols were prepared under microwave irradiation through one-pot reactions, and these quinolines/ benzo[h]quinolines were evaluated for potential antibacterial activity.

Synthesis of novel benzo[h]quinolines: Wound healing, antibacterial, DNA binding and in vitro antioxidant activity
摘要:
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 (22.76 +/- 0.14), Bacillus subtilis (20.63 +/- 0.24), and Streptococcus pyogenes (19.54 +/- 0.20) over sulfur containing compound 3. To validate the ethnotherapeutic claims of the synthetic compounds in skin diseases, wound healing activity was studied, besides antioxidant activity to understand the mechanism of wound healing. The interaction behavior of these compounds with DNA was investigated by absorption spectra (obtained K-b constant for 3 is 2.7 x 10(5) and for 4 is 3.8 x 10(6)), viscosity, and thermal denaturation studies. Finally, the results show that the DNA intercalated 314 compounds are strong antioxidants; they show significan wound healing activity and protect oxidative DNA damage from harmful free radical reactions.
