anamide (GUF-6) were synthesized as bioisosteres of the NSAIDs paracetamol, ibuprofen, and naproxen, respectively. All these compounds were characterized by spectroscopic and spectrometric analysis. Antinociceptive activity of GUF-1 to GUF-6 was evaluated using the formalin test in rats. Pharmacological responses of GUF-1, GUF-2 (hybrids), and GUF-5 (bioisostere) demonstrated significant antinociceptive
这项工作的目的是设计,合成和表征来自已知非甾体抗炎药(NSAIDs)的一系列新的生物等排体和杂种的潜在抗伤害感受和抗炎活性。化合物4-(乙酰氨基)苯基(2S)-2-(6-甲氧基-2-萘基)丙酸酯(GUF-1)和4-(乙酰氨基)苯基2-(R,S)-(4-异丁基苯基)丙酸酯(GUF-2)被合成为杂种(也称为异二聚体);而命名为2-(R,S)-(4-异丁基苯基)-N-1H-四唑-5-基丙酰胺(GUF-3),(2S)-2-(6-甲氧基-2-萘基)-N- 1H-四唑-5-基丙酰胺(GUF-4),[2-(R,S)-N-羟基-2- [4-(2-甲基丙基)苯基]丙酰胺](GUF-5)和(2S)合成了-N-羟基-2-(6-甲氧基-2-萘基)丙酰胺(GUF-6)作为NSAID对乙酰氨基酚,布洛芬和萘普生的生物等排体。所有这些化合物都通过光谱和光谱分析来表征。使用福尔马林试验评估大鼠中GUF-1对GUF-6的抗
