poses providing interactions with the hinge region of the tyrosine kinase (TK). Besides the effect on expression, this in silico investigation predicts the possibility of direct binding between the newcoumarin derivatives and the EGFR TK. Moreover, computational calculation for ADME properties for the most active compounds 9d, 9e, 10c, and 11c revealed the expected high gastrointestinal tract absorption

Abstract A series of novel 3-(2-oxo-2H-chromen-3-yl)-1-(4-(2-oxo-2H-chromen-3-yl)thiazol-2-yl)-5-aryl-1H-pyrazol-1-ium bromides have been prepared through a one-pot three-component cyclocondensation of various coumarin chalcones, thiosemicarbazide and 2-bromocoumarin. The key features of this reaction are the incorporation of four heterocyclic rings in the structure of target products, using commonly
摘要 一系列新颖的3-(2-oxo-2 H -chromen-3-yl)-1-(4-(2-oxo-2 H -chromen-3-yl)thiazol-2-yl)-5-芳基-1高通过各种香豆素查尔酮,硫代氨基脲和2-溴香豆素的一锅式三组分环缩合反应制得了-吡唑-1-溴化溴化物。该反应的关键特征是使用通常可得的和廉价的催化剂,在目标产物的结构中引入四个杂环,高收率和简单的反应条件。最终的盐产物是通过吡唑部分的氮原子对质子的自捕获而获得的。简便的后处理和温和的反应条件是该方案的显着特征。检查了合成产品的抗氧化,抗菌和抗真菌活性。与参考文献相比,大多数化合物显示出良好的生物学能力。 图形概要

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
