We have described a simple, convenient, and high‐yielding one‐pot synthesis of novel azo chromene derivatives via a three‐component reaction of various azo aldehydes with dimedone and malononitrile using 10 mol% of 1,8‐diazabicyclo[5.4.0]undec‐7‐ene (DBU) as catalyst and ethanol as solvent at reflux condition. All the synthesized compounds have been characterized using Fourier‐transform infrared spectroscopy
我们已经描述了使用10 mol%的1,8-二氮杂双环[3.4.0]通过各种偶氮醛与二甲酮和丙二腈的三组分反应,简单,方便且高收率的新型偶氮苯二烯衍生物的一锅法合成[5.4.0]在回流条件下,十一碳烯(DBU)作为催化剂,乙醇作为溶剂。所有合成的化合物均使用傅里叶变换红外光谱(FT-IR),1 H NMR,13 C NMR和HR-MS光谱进行了表征,并进行了分子对接以探索人类胎盘芳香化酶细胞色素P450和环氧合酶的新型抑制剂。 2种酶。在所有对接的化合物中,化合物(E)-2-氨基-4-(4,4-二甲基-2,6-二氧代环己基)-6-((3-甲氧基苯基)二氮烯基4 H-色烯-3-腈(4度)与抑制因子(Ki)为1.66 nM的人胎盘芳香化酶细胞色素P450酶(PDB:3EQM)的活性位点具有良好的结合亲和力,化合物4o也与环氧合酶2酶的活性位点(PDB:6COX)具有良好的结合力抑制常数(Ki)为367
Synthesis, anti‐inflammatory activity, and molecular docking study of novel azo bis antipyrine derivatives against cyclooxygenase‐2 enzyme
We have synthesized a new series of azo‐bis antipyrine derivatives from a one‐pot multicomponent Knoevenagel/Michael addition reaction of antipyrine, with a diversity of azo aldehydes in ethanol and L‐Proline as a catalyst under reflux condition. The anti‐inflammatory activity of the final products was assessed using the inhibition of albumin denaturation technique. Compound 3f showed an inhibitory
