Abstract
Background:
An enzyme called urease assists highly pathogenic bacteria in colonizing and
maintaining themselves. Accordingly, inhibiting urease enzymes has been shown to be a promising strategy
for preventing ureolytic bacterial infections.
Objective:
This study aimed to synthesize and evaluate the bioactivity of a series of semicarbazone derivatives.
Methods:
A series of piperazine-based semicarbazone derivatives 5a-o were synthesized and isolated, and
their structures were elucidated by 1H-NMR and 13C-NMR spectroscopic techniques besides MS and
elemental analysis. The urease inhibition activity of these compounds was evaluated using the standard
urease enzyme inhibition kit. An MTT assay was performed on two different cell lines (NIH-3T3 and
MCF-7) to investigate the cytotoxicity profile.
Results:
All semicarbazone 5a-o exhibited higher urease inhibition activity (3.95–6.62 μM) than the reference
standards thiourea and hydroxyurea (IC50: 22 and 100 μM, respectively). Derivatives 5m and 5o
exhibited the best activity with the IC50 values of 3.95 and 4.05 μM, respectively. Investigating the cytotoxicity
profile of the target compound showed that all compounds 5a-o have IC50 values higher than 50
μM for both tested cell lines.
Conclusion:
The results showed that semicarbazone derivatives could be highly effective as urease inhibitors.

Abstract
Urease is an enzyme associated with the degradation of urea, an important nitrogen fertilizer in agriculture. Thus, this current report describes the use of a paper-based analytical device (UrePAD) designed to contain a microzone array for colorimetric determination of urease activity in soils in the absence/presence of potential enzyme inhibitors. The UrePAD can be used at the point-of-need (point-of-care), and it offers advantages such as low cost, simplicity in handling, low sample/reagent volumes, and no use of toxic reagents. The acid-base indicator phenol red was used to monitor the urea hydrolysis reaction catalyzed by urease in the evaluated systems. The images were digitalized in a bench scanner, and the analysis was performed using Corel Draw X8 software. The device offered a LOD of 0.10 U mL-1 with linearity between 0.25 and 4.0 U mL-1 and a relative standard deviation ≤ 1.38%. UrePAD was tested in four soil samples of different characteristics and with eight urease inhibitors of varied classes. The results obtained through the proposed device did not differ statistically (95% confidence interval) from those employing the classic method based on the Berthelot reaction, thus indicating that UrePAD was effective for determining urease activity and screening inhibitors, besides showing the capacity to simplify fieldwork involving the application of urea in the soil.

Abstract
The enzyme urease is an essential colonizing factor of the notorious carcinogenic pathogen Helicobacter pylori (H. pylori), conferring acid resistance to the bacterium. Recently, antibiotic resistant strains have emerged globally with little to no alternative treatment available. In this study we propose novel urease inhibitors capable of controlling infection by H. pylori and other pathogenic bacteria. We employed hierarchal computational approaches to screen new urease inhibitors from commercial chemical databases followed by in vitro anti-urease assays. Initially ROCS shape-based screening was performed using o-chloro-hippurohydroxamic acid followed by molecular docking studies. Out of 1.83 million compounds, 1700 compounds were retrieved based on having a ROCS Tanimoto combo score in the range of values from 1.216 to 1.679. These compounds were further screened using molecular docking simulations and the 100 top ranked compounds were selected based on their Glide score. After structural classification of the top ranked compounds, eight compounds were selected and purchased for biological assays. The plausible binding modes of the most active compounds were also confirmed using molecular dynamics (MD) simulations. Compounds 1, 2 and 3 demonstrated good urease inhibitory properties (IC50 = 0.32, 0.68 and 0.42 μM) compared to the other compounds. Enzyme kinetic studies revealed that compounds 1 and 3 are competitive inhibitors while 2 is a mixed type inhibitor of the urease enzyme. Cell based urease inhibition and MTT assay showed that these compounds blocked H. pylori urease activity, affecting bacterial growth and acid tolerance. The enzyme urease is an essential colonizing factor of the notorious carcinogenic pathogen Helicobacter pylori (H. pylori), conferring acid resistance to the bacterium.![]()
