Urease inhibitors play the role of potential drugs in serious infections caused by Proteus and related species in the urinary tract, as well as Helicobacter pylori in the gastrointestinal tract.
There are two key steps that are widely targeted by stabilising technology--(i) the hydrolysis of urea to ammonium carbonate ([(N[H.sub.4]).sub.2]C[O.sub.3]) by urease inhibitors (UIs) (Andrews et al.
In this case, using urease inhibitors is an efficient alternative to reduce the losses through N[H.sub.3] volatilization and increase N use efficiency (Soares et al., 2012).
In the past decades, many urease inhibitors like phosphorodiamidates, hydroxamic acid derivatives have been investigated but because of their instability or toxicity they are prevented from being employed in vivo and part of them had side effects.
To eradicate and control bacterial infections urease production is targeted by therapeutic regimens such as urease inhibitors. Inhibitors of urease are useful against some infectious disorders including gastric pathologies and urinary tract infection, pyelonephritis, urinary catheter obstruction, peptic ulceration and cancer.
Therefore, both in early and late rice, the grain and straw yields of rice increased gradually when the ratio of urease inhibitors increased from 0.50 to 1.00%, but decreased when NBPT rate was more than 1.00%.
To summarize, urease inhibitors are highly potential target for different pathological conditions induced urease hyperactivity.
The coating of urea with sulphur, urease inhibitors and other biodegradable materials are the possible remedies to reduce N loss and enhance urea efficiency (Shaviv, 2001).
A number of synthetic compounds including imidazoles, hydroxamic acids, and phosphazenes are effective urease inhibitors, but limited studies have been conducted on natural products (Ahmad et al.
In this regard, urease inhibitors have gained tremendous attention over the years which resulted into the discovery of numerous inhibitors [5, 7-11].
It was reported that some urease inhibitors depressed jack-bean urease activities by interacting with the sulfhydryl group of residues, especially the Cysteine-592 [4].
