A new method was developed for synthesis of 1,2,4-triazole-3-carboxylates 5a–p and 6 from nitrilimines 3a–p through amination and heterocyclization two-steps reactions. All of 1,2,4-triazole-3-carboxylates 5 and 6 were characterized by spectroscopy technique. Based on the SAR study of anti-inflammation activity, most of 5a–p showed potential anti-inflammatory activity on NO inhibition in LPS-induced
通过胺化和杂环化两步反应,从亚胺3a - p合成1,2,4-三唑-3-羧酸5a - p和6的新方法得到了发展。通过光谱技术表征所有1,2,4-三唑-3-羧酸盐5和6。根据SAR的抗炎活性研究,与Celecoxib和消炎痛相比,大多数5a - p对LPS诱导的RAW 264.7细胞(IC 50 <7.0 nM)对NO抑制具有潜在的抗炎活性。几种可能的化合物5b – h,5j,5升,5N和5O进行体外环氧合酶COX-1 / COX-2抑制试验。化合物5d表现出非凡的COX-2抑制作用(IC 50 = 17.9 nM)和最佳选择性(COX-1 / COX-2 = 1080)。此外,与10 mg / kg消炎痛相比,5 mg / kg的化合物5d在体内的抗炎和胃保护作用也更好。已经评估了将5d对接至COX-2结合袋的实验。根据生物活性实验数据,潜在的候选药物5d比消炎痛具有更好的抗炎作用。
