Twenty-five benzophenone semicarbazones and thiosemicarbazones 3–27 were synthesized starting from benzophenones via hydrazones treated with different aryl isocyanates and isothiocyantes under reflux. All synthetic derivatives were evaluated for their urease inhibitory potential. Good to moderate inhibition trend against urease was observed with the IC50 values in the range of 8.7–119.5 µM, when compared
二十五个二苯甲酮缩氨基脲和缩氨基硫脲3 - 27合成通过与在回流下不同的芳基异氰酸酯和isothiocyantes处理腙从二苯甲酮开始。评价所有合成衍生物的脲酶抑制潜力。与标准硫脲相比(IC 50 = 21.2±1.3 µM),观察到的对脲酶的良好至中度抑制趋势,IC 50值为8.7-119.5 µM 。化合物15的抑制作用优于IC 50值为8.7±0.6 µM的标准品。化合物3,4,8,11 -14,16,和17与IC 50至43.6μM的26.1的范围内的值,表现出优良至适中的活动,同时化合物9(IC 50 = 119.5±1.6μM)显示非常弱的活性。进行了对活性最高的化合物15和17的酶动力学研究,以推导它们的抑制方式和解离常数K i。
