A new series of 1-(4-aminosulfonylphenyl)-3,5-diaryl pyrazolines (5) was synthesized by the reaction of appropriate chalcones 3 with 4-hydrazinobenzenesulfonamide hydrochloride (4) in ethanol in the presence of catalytic amount of acetic acid. All newly synthesized compounds were in vivo evaluated for their antiinflammatory activity using carrageenan-induced rat paw edema assay. Five of the newly synthesized
在催化量的乙酸存在下,使合适的查尔酮3与4-肼基苯磺酰胺盐酸盐(4)在乙醇中反应,合成了一系列新的1-(4-氨基磺酰基苯基)-3,5-二芳基吡唑啉(5)。使用角叉菜胶诱导的大鼠爪水肿测定法在体内评估所有新合成的化合物的抗炎活性。新合成的5种化合物5d,5g,5h,5i和5m显示出显着的抗炎活性,角叉菜胶注射后3小时抑制作用大于55%。评价所有新合成的化合物对两种革兰氏阳性细菌(金黄色葡萄球菌和枯草芽孢杆菌)的体外抗菌活性;两种革兰氏阴性细菌(大肠杆菌和铜绿假单胞菌)和两种酵母菌(白色念珠菌和酿酒酵母)。一些新合成的化合物5a,5f,5g,5h,5j和5k对啤酒酵母显示出优异的抗真菌活性,比参考药物两性霉素B强。
