Synthesis, molecular docking studies, and antimicrobial evaluation of new structurally diverse ureas.

A series of new urea derivatives (3a-p) have been synthesized from readily available isocyanates and amines in good to high yields. All synthesized compounds were fully characterized using 1H NMR, 13C NMR, IR, and mass spectrometry. Additionally, the structure of the compound (3n) was confirmed by single-crystal X-ray diffraction. Furthermore, all compounds were evaluated for antimicrobial activity against five bacteria and two fungi. Last but not the least, molecular docking studies with Candida albicans dihydropteroate synthetase were performed and the results are presented herein.
