4-substituted benzensulfonyl chlorides afforded the compounds containing 4-nitro/aminophenyl sulfonylamino moiety in the cephalosporanic acid skeleton (2, 4). The synthesis of the cephalosporanic acid derivatives containing 1,3-thiazole or 5-oxo-1,3-thiazolidine nucleus and sulfonamide function (8a, 8b, 10) was performed starting from 7-ACA by several steps. The reaction of 7-ACA with [4-(2-fluoro-4-nitroph
7-ACA与4-取代的苯磺酰基氯化物处理,得到含有所述化合物的4-硝基/氨基苯基磺酰基部分在头孢烷酸骨架(2,4)。从7-ACA开始,通过几个步骤进行包含1,3-噻唑或5-氧代-1,3-噻唑烷核和磺酰胺官能团(8a,8b,10)的头孢烷酸衍生物的合成。7-ACA与[4-(2-氟-4-硝基苯基)哌嗪-1-基]乙酰氯的反应得到相应的7-[4-(2-氟-4-硝基苯基)哌嗪-1-基] ]乙酰基}氨基衍生物(13)。 筛选合成的化合物的抗微生物和抗脲酶活性。发现其中一些对测试微生物具有良好的中度抗菌活性。观察到化合物5d具有中等的抗脲酶活性。
