yields of products and column-free synthesis. The synthesized compounds were evaluated in vitro for their antimicrobialactivity. Among the synthesized compounds, namely 3-(5-(4-hydroxy-3-methoxyphenyl)-4,5-dihydro-1H-pyrazol-3-yl)-2H-chromen-2-one (5f) was found to be the most potent D-alanine-D-alanine ligase enzyme inhibitor, with an IC50 value 106 μM, and the compound 3-(5-(p-tolyl)-4,5-dihydro-1H-p
