Synthesis of Coumarins Linked With 1,2,3-Triazoles under Microwave Irradiation and Evaluation of their Antimicrobial and Antioxidant Activity
Abstract: A series of coumarin derivatives linked with 1,2,3-triazoles has been synthesized by utilizing the copper catalyzed azide-alkyne cycloaddition reaction and were screened for their antimicrobial and antioxidant properties. Some of the compounds displayed promising antibacterial activities (MIC ranging from 5-150 µg/mL) and moderate antifungal activities as compared to the respective standards. The compounds 4k and 4g displayed good antibacterial activity when compared with the standard, Ciprofloxacin, and 4n exhibited better antifungal activity when compared to other synthesized compounds. The in silico docking studies of the active compounds were carried out against the gyrase enzyme and from those studies, it was acknowledged that 4k possessed significant hydrogen bonding and hydrophobic interactions which could be the plausible reason for its superior activity as compared to the other synthesized compounds. The compounds 4h and 4q showed promising antioxidant activity when compared with the standard, BHT, which could be attributed to the presence of electron donating substituents.
