Özet

A new series of 2,3-disubstituted quinazolin-4(3H)-one compounds including oxadiazole and furan rings was synthesized. Their inhibitory activities on urease were assessed in vitro. All newly synthesized compounds exhibited potent urease inhibitory activity in the range of IC50 = 1.55 +/- 0.07-2.65 +/- 0.08 mu g/mL, when compared with the standard urease inhibitors such as thiourea (IC50 = 15.08 +/- 0.71 mu g/mL) and acetohydroxamic acid (IC50 = 21.05 +/- 0.96 mu g/mL). 2,3-Disubstituted quinazolin-4(3H)-one derivatives containing furan ring (3a-e) were found to be the most active inhibitors when compared with the compounds 2a-e bearing oxadiazole ring. Compound 3a, bearing 4-chloro group on phenyl ring, was found as the most effective inhibitor of urease with the IC50 value of 1.55 +/- 0.11 mu g/mL. The molecular docking studies of the newly synthesized compounds were performed to identify the probable binding modes in the active site of the Jack bean urease (JBU) enzymes.
