Urease inhibitors are a class of drug for H.pilory treatment.
Urease inhibitors are potentially useful tools for controlling or reducing gaseous losses of ammonia following fertilization with urea. They can restrict urea hydrolysis for up to 7 to 14 days, after which rain, irrigation, or soil mixing would be required to further restrict ammonia losses.
The observations that urease due to its high substrate (urea) specificity can only bind to a few inhibitors with a similar binding mode as urea is also discussed. Several non-covalent interactions including hydrogen bonds and hydrophobic contacts stabilize the enzyme-inhibitor complex.
The most widely used urease inhibitor is N-(n-Butyl) triphosphoric triamide (NBTPT), which converts to active NBPT (N-(n-Butyl) phosphoric triamide). Other widely studied urease inhibitors include phenylphosphorodiamidate (PPD/PPDA) and hydroquinone.
Recent drug studies are highly focused on heterocyclic ring systems. Thiadiazoles are one of the privileged structural fragments. Fused systems containing the thiadiazole ring give rise to compounds with varied bioactivities, such as anticancer [1], antimicrobial [2, 3], and antiviral [4] properties. Currently, compounds A [5] and B [6, 7] (Figure 1) are in clinical trials, and several other 1,3,4-thiadiazole derivatives including C [8, 9], D [10], and the parent compound 2-amino-5-mercapto-1,3,4-thiadiazole (AMT) [11–15] display a variety of biological activities. Several synthetic strategies to AMT have been reported [16]. The easy accessibility of AMT prompted us to prepare a new series of 2-amino-5-mercapto-1,3,4-thiadiazole derivatives
