In present, we have performed the Michaelis–Menten kinetics studies of urease inhibitors (6a–o), having basic skeleton of acetamide hybrids of N-substituted 1,3,4-oxadiazoles and piperidines. From the Lineweaver-Burk plot, Dixon plot and their secondary replots, it has been confirmed that all the compounds have inhibited the enzyme competitively with Ki values of in range from 3.11 ± 0.2 to 5.20 ± 0.7 μM. Compound 6a was found to have lowest Ki among the series, while compounds 6d, 6e, 6gand 6i were found subsequently the excellent Ki values after 6a. Molecular docking has supported their types of inhibitions and structure activity-relationship. Most frequently, the nitro group oxygen atoms were found in contact with nickel ions of the active site. Moreover, all the compounds were subjected to toxicity tests and were found nontoxic against human neutrophils and plants, respectively.

In the current paper, through a convergent multi-step approach, a library of novel indole-phenyltriazole hybrids containing an amide moiety (9a-k) was synthesized. The structural verification of all synthesized molecules was accomplished by CHN and spectral analyses data. These synthesized bi-heterocyclic derivatives (9a-k) were evaluated for their anti-ulcer potential by inhibitory action against Jack bean urease enzyme and subsequently their structure-activity relationship was perceived. Moreover, these compounds were inspected for cytotoxic profile by hemolytic activity and it was professed that nearly all the synthesized compounds showed low cytotoxicity. In addition, free radical scavenging activity and kinetic analysis were also carried out for these compounds to understand their mode of inhibition. So, it was summated that these derivatives might lead to further research gateways for obtaining better and safe anti-ulcer agents.
