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

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
organometallic recyclable catalyst in the synthesis of coumarin–chalcone hybrids through the Claisen–Schmidt condensation of different aromatic aldehydes and 3-acetyl coumarin. The nanocomposite increased the rate and facility of the aforementioned reaction and represented a strong influence in the green synthesis of different coumarin–chalcone derivatives. The nanocatalyst has been characterized by N2 adsorption–desorption
摘要 固定在石墨化碳氮化物(ZnS NPs / gC 3 N 4)纳米复合材料上的氧化锌纳米颗粒通过有机碳可循环利用催化剂,通过不同芳族醛和3-乙酰香豆素的Claisen-Schmidt缩合反应合成香豆素-查尔酮杂化物。纳米复合材料提高了上述反应的速率和便利性,并且在不同香豆素-查尔酮衍生物的绿色合成中表现出强大的影响力。纳米催化剂的特征在于N 2吸附-解吸,傅立叶变换红外光谱,扫描电子显微镜,粉末X射线衍射和能量色散光谱。这种新颖且可持续的方法的优点是香豆素-查尔酮化合物的收率高,反应时间短,对环境无害,ZnS NPs / gC 3 N 4的可回收性以及可重用性,而不会显着降低催化活性。 图形概要

A novel series of coumarin–pyrazoline hybrids 3a–f, 4a–c and 5a–c have been synthesized and tested for their antiproliferative activity against the breast cancer cell line MCF-7. The most active compounds 3d, 3e, 3f, 5a and 5c were also evaluated for their ability to inhibit EGFR expression with reference to erlotinib. In silico studies using rigid docking, flexible docking and molecular dynamics were
