compounds exhibited potent urease inhibitory activity in the range of IC50 = 1.55 ± 0.07–2.65 ± 0.08 µg/mL, when compared with the standard urease inhibitors such as thiourea (IC50 = 15.08 ± 0.71 µg/mL) and acetohydroxamic acid (IC50 = 21.05 ± 0.96 µg/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
A new series of 2,3‐disubstituted quinazolin‐4(3H)‐one derivatives bearing triazole and thiadiazole nucleus has been synthesized and then screened for their urease inhibition properties. All synthesized compounds showed outstanding urease inhibitory potentials with IC50 values ranging between 0.25 ± 0.01 and 18.00 ± 0.64 μg/mL when compared with standard inhibitors thiourea (IC50 = 15.08 ± 0.71 μg/mL)
合成了一系列新的带有三唑和噻二唑核的2,3-二取代喹唑啉-4(3 H)-one衍生物,然后对其脲酶抑制特性进行了筛选。与标准抑制剂硫脲(IC 50 = 15.08±0.71μg/ mL)和乙酰氧肟酸(IC 50 = 21.05± )相比,所有合成的化合物均显示出出色的脲酶抑制潜能,IC 50值在0.25±0.01和18.00±0.64μg/ mL之间。0.96μg/ mL)。所有新分子均通过1 H NMR,13 C NMR和MS表征。
