A reliable and sensitive method was used to compare the analgesic activities of salicylic acid and aspirin (acetylsalicylic acid) and several phenoxy substituted isosteric pairs. Those isosteric compounds studied did not show analgesic activity. The analgesic activity of aspirin was more than twofold greater than that of salicylic acid.
采用一种可靠且灵敏的方法比较了水杨酸、阿司匹林(乙酰水杨酸)以及几对苯氧基取代的等排体的镇痛活性。所研究的那些等排体化合物未显示出镇痛活性。阿司匹林的镇痛活性比水杨酸的镇痛活性强两倍多。
