A new series of quinazolinone hybrid molecules containing coumarin, furan, 1,2,4‐triazole and 1,2,4‐thiadiazole rings was designed, synthesized, and screened for their urease inhibition activities. All newly synthesized compounds showed outstanding urease inhibitory potentials with IC50 values ranging between 1.26 ± 0.07 and 7.35 ± 0.31 μg/mL. Among the series, coumarin derivatives (10a–d) exhibited
设计、合成了一系列新的含有香豆素、呋喃、1,2,4-三唑和1,2,4-噻二唑环的喹唑啉酮杂化分子,并筛选了它们的脲酶抑制活性。所有新合成的化合物都显示出出色的脲酶抑制潜力,IC50 值范围在 1.26 ± 0.07 和 7.35 ± 0.31 μg/mL 之间。在该系列中,与乙酰异羟肟酸和硫脲等标准脲酶抑制剂相比,香豆素衍生物(10a-d)在 IC50 = 1.26 ± 0.07 至 1.82 ± 0.10 μg/mL 范围内表现出最佳的脲酶抑制作用(IC50 = 21.05 ± 0.96 和 15.08 ± 0.71 μg/mL)。还进行了分子对接研究以分析化合物 10b 的结合模式,并支持实验结果。
