mg, p.o.) possessed anti-inflammatory activity. In the Carrageenan-induced edema test in rat paw, the activity ranged from 28 to 47% for 3a-3d and 44 to 63% for 4a-4d, with indomethacin (10 mg/kg, p.o.), used as the standard reference drug, showing 88.5% protection. The compounds (1 mM) were also tested for the inhibition of bovine serum albumin denaturation, and this activity ranged from 27 to 68%
通过将相应的N1-[[()环合,合成了各种5-[[[acetamidophen-4-yl)oxy]甲基] -2-(对位苯氨基)-1,3,4-恶二唑(4a-4d)。对乙酰氨基苯-4-基)氧基]乙酰基] -N4-(对位取代的苯基氨基)-3-硫代氨基脲(3a-3d)。四种硫代氨基脲(250 mg / kg,口服(口服))和相应的恶二唑(250 mg,口服)均具有抗炎活性。在角叉菜胶诱导的大鼠足水肿试验中,活性为3a-3d,范围为28%至47%,4a-4d为44%至63%,吲哚美辛(10 mg / kg,口服)用作标准参考药物,显示出88.5%的保护。还测试了化合物(1 mM)对牛血清白蛋白变性的抑制作用,该活性为27%至68%。在3a-4d的抗炎活性与抑制牛血清白蛋白变性之间没有相关性。这些化合物的低毒性通过其较高的约50%致死剂量(LD50)值来反映,范围从2000至2500 mg / kg。
