their corresponding condensed derivatives 3,6-disubstituted 7H-1,2,4-triazolo[3,4-b]-1,3,4-thiadiazines (1a–4c) were synthesized and evaluated for their analgesic/anti-inflammatory activities. All synthesized compounds were also tested for their gastric toxicity and antioxidant activity on acute administration. Most of the compounds showed significant activity in both carrageenan-induced oedema and acetic
在这项研究中,一类新的4-氨基-3-取代的-1,2,4-三唑-5-硫酮(1 - 4)和它们的相应的冷凝衍生物3,6-二取代的7 ħ -1,2,4- -triazolo [3,4- b ] -1,3,4-噻二嗪(1a – 4c合成)并评估其镇痛/抗炎活性。还测试了所有合成的化合物在急性给药时的胃毒性和抗氧化活性。除了可忽略的胃肠道毒性外,大多数化合物在角叉菜胶引起的水肿和乙酸引起的扭体试验中均显示出显着的活性。表现出较少的致溃疡作用的化合物也表现出较少的脂质过氧化(LPO)水平。使用将氟或氯化物置于苯环上稠合环第六位的化合物获得了最有希望的结果。
