Multicomponent Synthesis of 2, 4, 6-Triarylpyridine Analogues As Antibacterial And Antiurease Agents

Five new 2,4,6-triarylpyridine analogues with potential biological importance have been synthesized using the multicomponent reaction (MCR) solid support catalyst synthetic approach. This green synthesis furnished method simplicity, reduce reaction time, and excellent yield, along with an additional feature of catalyst reusability. A number of spectroscopic techniques such as 1H-NMR, IR, and mass spectrometry, confirmed structures of the newly synthesized compounds. Antibacterial and anti-urease activities of these compounds were evaluated. Results revealed that compounds 4a, 4c, 4d, and 4e exhibit significant inhibition against gram-positive bacterial pathogens. Furthermore, all synthesized compounds showed potent urease inhibitory activity with IC50 values ranging from 12.8 ± 1.04 to 23.7 ± 0.23 µM when compared with the standard inhibitor thiourea (IC50 21.0 ± 0.23 µM).In addition, the synthesized derivatives were subjected to density functional theory (DFT) calculations (DFT) to determine the energy of the molecules having biological potential.
