Abstract: Although a diverse range of chemical entities offering striking therapeutic potential against urease enzyme has been reported, the key challenges (toxicity and safety) associated with these inhibitors create a large unmet medical need to unveil new, potent and safe inhibitors of urease enzyme. In this pursuit, the present study demonstrates the successful synthesis of carbazole-chalcone hybrids (4a-n) in good yields. The evaluation of the preliminary in vitro biological results showed that selected members of the investigated library of hybrid compounds possess excellent urease inhibitory efficacy. In particular, compounds 4c and 4k were the most potent inhibitors with lowest IC values of 8.93 ± 0.21 and 6.88 ± 0.42 μM, respectively. Molecular docking analysis of the most potent inhibitor 4k suggests that the compound is fitted neatly at the active site interface and mediates interaction with both nickel atoms present in the active site. Several other obvious interactions including metal-carbonyl contact, hydrogen bonding and hydrophobic interactions were also observed, playing a crucial part in the stabilization of 4k in the active site of urease.
