Urease inhibitors: A review
Urease inhibitors possess a wide application in agriculture, clinical science and understanding of enzyme kinetics. These inhibitors play a significant role in reducing the loss of nitrogen from urea fertilizer in the form of volatile ammonia and, thus, improve the utility of urea based fertilizers. Their impact as an effective drug against urease producing bacterial infection is well documente...
متن کاملN-substituted hydroxyureas as urease inhibitors.

متن کاملKinetic and Thermodynamic Behaviors of Soil Urease as Affected by Urease Inhibitors
The kinetic characteristics of soil urease have attracted great attention, but little information was available on its kinetic and thermodynamic behaviors as affected by urease inhibitors and temperature. With black soil (Pachic Udic Mollisol) in Heilongjiang Province of Northeast China as a test soil, an incubation test was conducted to investigate the effect of urease inhibitors (hydroquinone...
