Five series of 1,4-phthalazinedione derivatives were synthesized in good yields. Vasorelaxant activity of these new derivatives was measured on either intact or endothelium-denuded isolated rat thoracic aortic rings pre-contracted with phenylephrine. Most of studied compounds, substituted in both nitrogen atoms, attained practically the total relaxation of the organ at low micromolar concentrations
以高收率合成了五个系列的1,4-酞嗪二酮衍生物。在与去氧肾上腺素预收缩的完整或内皮剥脱的大鼠胸主动脉环上测量了这些新衍生物的血管舒张活性。大多数研究的化合物都被两个氮原子取代,在低微摩尔浓度下,实际上达到了器官的完全松弛。对于大多数研究的化合物,功能性内皮的存在会显着降低EC 50值。建立了一些构效关系,化合物2d和5d可被视为进一步修饰的新线索。
