phenyl)-1H-pyrazole-1-sulfonate exhibited excellent anti-inflammatory activity (% inhibition of auricular edemas = 27.0 and 35.9, respectively); the in vivo analgesic activity of phenyl 5-methyl-3-(p-tolyl)-1H-pyrazole-1-sulfonate and 2-chlorophenyl 5-methyl-3-(p-tolyl)-1H-pyrazole-1-sulfonate was confirmed to be effective (inhibition ratio of writhing = 50.7% and 48.5% separately), and compounds phenyl 5-
基于一种新的吡唑磺酸盐合成方法,设计并合成了一类具有吡唑N-芳基磺酸盐基本结构的新型分子。进行深入研究的兴趣源于这些化合物在初步动物实验中表现出的相当明显的抗炎作用。通过R 1、R 2和R 3基团的不同取代,合成了一系列化合物。在该系列中,4-iodophenyl 5-methyl-3-(p-tolyl)-1H-pyrazole-1-sulfonate 和 phenyl 5-methyl-3-(4-(trifluoromethyl) phenyl)-1H-pyrazole-1-sulfonate表现出优异的抗炎活性(耳廓水肿抑制百分比分别为 27.0 和 35.9);在体内5-甲基-3-(p-tolyl)-1H-pyrazole-1-sulfonate 和 2-chlorophenyl 5-methyl-3-(p-tolyl)-1H-pyrazole-1-sulfonate 的镇痛活性被证实为有效(扭体抑制率分别为50
