Nitrooxymethyl-substituted analogues of celecoxib were synthesized and tested for their cyclooxygenase (COX)-inhibiting, vasodilator, and anti-aggregatory activities, as well as for their metabolic stability in human serum and whole blood. The results showed their potency and selectivity in inhibiting the COX isoforms, evaluated in whole human blood, as well as their anti-aggregatory activity to depend
合成了塞来昔布的硝基氧甲基取代的类似物,并测试了它们对环加氧酶(COX)的抑制,血管舒张和抗聚集活性,以及它们在人血清和全血中的代谢稳定性。结果表明,它们在全人类血液中抑制COX亚型的能力和选择性,以及它们的抗聚集活性密切依赖于NO供体部分的引入位置。所有产品均通过cGMP依赖性机制以剂量依赖性方式扩张了与去氧肾上腺素预收缩的大鼠主动脉条。它们在人血清中稳定,而在血液中则被代谢转化,主要转化为相关的醇。
