the vasorelaxant activities of chalcones, nine hybrid chalcone derivatives conjugated with nitric oxide (NO) donor or 1,4-dihydropyridyl (1,4-DHP) moiety were designed and synthesized based on molecular hybridization strategy. Their vasorelaxant activities were evaluated in aortic rings with endothelium pre-contracted with phenylephrine (PE). All of these compounds showed preferable vasorelaxant activities
为了进一步改善查尔酮的血管舒张活性,基于分子杂交策略设计合成了九种杂化查尔酮衍生物,它们与一氧化氮(NO)供体或1,4-二氢吡啶基(1,4-DHP)部分共轭。他们的血管舒张活性被评估在主动脉环与苯肾上腺素(PE)预收缩的内皮细胞。所有这些化合物均表现出优选的血管舒张活性,比其母体化合物更有效。化合物8c和15c是最有效的化合物,将成为开发新型血管松弛剂的有前途的结构模板。
