Binding
Inhibition Assay: Reaction mixtures consisting of 25 μL (1 unit/well) of Jack bean (Canavalia ensiformis) urease, 55 μL of buffer at pH 6.8, 100 mM of urea, and 5 μL of various concentrations of test compounds were incubated at 30° C. for 15 min in 96-well plates. Subsequently 45 μL phenol reagents (1% w/v phenol and 0.005% w/v sodium nitroprussside), and 70 μL of alkali reagent (0.5% w/v NaOH and 0.1% w/v NaOCl) were added to each well. Urease activity through indophenols method was confirmed by the production of ammonia, as described by Weatherburn [12]. After 50 min, the increasing absorbance at 630 nm was measured in a microplate reader SpectraMax M2 (Molecular Devices, CA, USA). All reactions were performed in triplicate in a final volume of 200 μL.
