A series of novel 2-(5-hydroxy-5-trifluoromethyl-4,5-dihydropyrazol-1-yl)-4-(coumarin-3-yl)thiazoles (6) were synthesized by condensing 3-(2-bromoacetyl)coumarins (4) with various 5-hydroxy-5-trifluoromethyl-4,5-dihydropyrazol-1-thiocarboxamides (5), obtained by the reaction of thiosemicarbazide with trifluoromethyl-β-diketones. All the tested compounds displayed significant to moderate in vivo anti-inflammatory
通过缩合3-(2-溴乙酰基)合成了一系列新型的2-(5-羟基-5-三氟甲基-4,5-二氢吡唑-1-基)-4-(香豆素-3-基)噻唑(6)。通过硫代氨基脲与三氟甲基-β-二酮反应制得的具有各种5-羟基-5-三氟甲基-4,5-二氢吡唑-1-硫代羧酰胺(5)的香豆素(4)。与标准药物消炎痛相比,所有测试的化合物均显示出显着至中等的体内抗炎活性,与头孢克肟相比,对三种革兰氏阳性和四种革兰氏阴性细菌均具有良好的广谱体外抗菌活性。
