3-substituted 1,5-diarylpyrroles bearing a nitrooxyalkyl side chain linked to different spacers were designed. New classes of pyrrole-derived nitrooxyalkyl inverse esters, carbonates, and ethers (7–10) as COX-2 selective inhibitors and NO donors were synthesized and are herein reported. By taking into account the metabolic conversion of nitrooxyalkyl ethers (9, 10) into corresponding alcohols, derivatives
设计了一系列带有连接到不同间隔基的硝基氧基烷基侧链的3-取代的1,5-二芳基吡咯。吡咯衍生的硝基氧基烷基逆酯,碳酸酯和醚(新类7 - 10),为COX-2选择性抑制剂和NO供体被合成并在本文中报告。通过考虑硝基氧基烷基醚(的代谢转化9,10)转换成相应的醇,衍生物17和18也进行了研究。硝基氧衍生物显示出NO依赖性血管舒张特性,而大多数化合物在体外实验模型中被证明是非常有效和选择性的COX-2抑制剂。对化合物9a的进一步体内研究,c和17a强调了良好的抗炎和抗伤害感受活性。化合物9c能够抑制白介素-1β(IL-1β)诱导的糖胺聚糖(GAG)释放,显示出软骨保护特性。最后,对化合物6c,d,9c和10b进行分子建模以及1 H和13 C-NMR研究,可以评估COX-2活性位点内这些分子的硝基氧基烷基酯和醚侧链的正确构型。
