5q showed significant activity against Urease enzyme and also exhibited good antioxidant potential. The compound 3‐(2‐oxo‐2H‐chromen‐3‐yl)‐5‐phenyl‐4,5‐dihydro‐1H‐pyrazole‐1‐carbothioamide (5n) was found to be superior agent in the series with an IC50 = 0.358 ± 0.017 μm compared to standard thiourea with an IC50 = 4720 ± 174 μm. To undermine the binding mode of inhibition kinetic studies were performed
目前的研究文章报道了香豆素基吡唑啉基硫代酰胺衍生物的合成及其作为杰克豆脲酶抑制剂的生物活性。通过氨基硫脲与新合成的查耳酮反应合成香豆基吡唑啉基硫代酰胺,以良好的收率提供产物,并通过重结晶纯化合成的化合物。香豆素基吡唑啉基硫代酰胺衍生物 5a - 5q 对脲酶显示出显着的活性,并且还表现出良好的抗氧化潜力。发现化合物 3-(2-oxo-2H-chromen-3-yl)-5-phenyl-4,5-dihydro-1H-pyrazole-1-carbothioamide (5n) 是该系列中的优良药物,IC50 = 0.358 ± 0.017 μm,与标准硫脲相比,IC50 = 4720 ± 174 μm。为了破坏抑制的结合模式,对大多数有效衍生物进行了动力学研究,发现化合物 5n 通过非竞争性抑制模式抑制脲酶。进行分子对接研究以描绘合成衍生物的结合亲和力。
