catalyst among the tested ones. The conjugates were evaluated for in-vitro xanthine oxidase activity. The results of the in-vitro assay were quite promising as some conjugates were endowed with remarkable inhibitory potential against the enzyme. HV-8, 11 and 12 were found to be high-potent inhibitors with HV-11 (the most potent inhibitor) possessing an IC50 value of 2.21 µM. The most active conjugate HV-11
摘要鉴于分子杂交技术在药物设计中的最新成功,本研究设计并合成了2,4-二芳基吡喃并[3,2-c] chromen-5(4H)-作为香豆素和查耳酮的缀合物。 。研究了各种路易斯酸在纯净条件下合成设计的共轭物的催化效率,并优化了SiO2(200-400目)-ZnCl2作为测试催化剂中的最佳催化剂。评价缀合物的体外黄嘌呤氧化酶活性。体外测定的结果非常有前途,因为某些结合物具有明显的抑制酶的潜力。发现HV-8、11和12是高效抑制剂,而HV-11(最有效的抑制剂)的IC50值为2.21 µM。评价活性最高的缀合物HV-11的抑制类型,发现其为混合型抑制剂。还计算了某些选定的共轭物对Lipinski规则的依从性。
