简介
In this paper, we report an efficient one-pot three-component reaction sequences comprising Cu(I)-catalyzed 1,3-dipolar cycloaddition (CuAAC) followed by Cu-catalyzed arylation of resulting 1,2,3-triazole in the presence of ionic liquid [Emim]BF4 under microwave conditions involving. The newly synthesized derivatives were screened for in vitro antibacterial inhibition potency against both gram +ve and gram −ve strains. Among the tested compounds, 4f exhibited significant inhibition activity with MIC value 3.12 µg/mL against B. subtilis and S. epidermidis which is two-fold higher than the standard ciprofloxacin (6.25 µg/mL) and also displayed equipotent activity to that of the positive control against S. aureus with MIC value 6.25 µg/mL. Conjugates of the series viz. 3f and 4b against S. aureus, and 4e against E. coli have also displayed promising results with MIC values 6.25 µg/mL which is comparable to the …
