The synthesis and study of the antioxidant and vasodilator properties of a new class of phenols able to release nitric oxide are described. The products were designed through a symbiotic approach using selected phenols and selected nitrooxy and furoxan NO-donors as reference models. The antioxidant activities of the hybrid products were assessed by detecting the 2-thiobarbituric acid reactive substances
描述了新型能够释放一氧化氮的酚类的抗氧化剂和血管扩张剂的合成和研究。这些产品是通过共生方法设计的,使用了选定的苯酚以及选定的硝基氧基和呋喃喃NO供体作为参考模型。通过检测在大鼠肝细胞的微粒体膜中存在的亚铁盐/抗坏血酸诱导的脂质的自氧化中产生的2-硫代巴比妥酸反应性物质(TBARS),可以评估杂化产物的抗氧化活性。在与去氧肾上腺素预收缩的大鼠主动脉条上评估血管舒张活性。一些产品(13、35、37、60-62、64)主要表现为血管扩张剂,而其他产品则表现为抗氧化剂(24、32、72),并且两种特性在19、41和68中相对平衡。
