and OCH3 substituents at aryl part were the most potent derivatives. Compound 14 (IC50 = 11.4 ± 0.4 μM) with a methyl substituent at ortho position was found to be the most active member of the series. Whereas, among halogen substituted derivatives, para substituted chloro compound 16 (IC50 = 13.7 ± 0.9 μM) showed good urease inhibitory activity. These synthetic derivatives were found to be non-cytotoxic
脲酶是酰胺水解酶家族的一种酶,可引起人体的各种病理状况,包括消化性溃疡,导管结壳,肾结石形成,肝昏迷,脑病等。因此,近年来寻找有效的脲酶抑制剂引起了科学上的重大关注。通过使色胺与不同的取代苯基异氰酸酯/异硫氰酸酯反应,合成了色胺的尿素和硫脲衍生物(1 – 25)。评估了合成化合物的脲酶抑制活性,在(IC 50)范围内对脲酶表现出良好的抑制潜力。 与标准硫脲(IC 50 = 21.2 ±1.3μM)相比,= 11.4±0.4–24.2±1.5μM )。在25种化合物中,发现14种比标准化合物更具活性。有限的结构活性关系表明,在芳基部分具有CH 3和OCH 3取代基的化合物是最有效的衍生物。发现 在邻位带有甲基取代基的化合物14(IC 50 = 11.4±0.4μM)是该系列中最活跃的成员。而在卤素取代的衍生物中,对位取代的氯化合物16(IC 50 = 13.7±0.9μM)表现出良好的脲酶
