chronic human diseases. Herein, we reported the synthesis of new nitrogen-containing diselenides by a simple and efficient synthetic route. The products were obtained in good to excellent yields and their identification and characterization were achieved by NMR and HRMS techniques. The new derivatives may represent promising structures with different biological activities, which can act against oxidative
为了开发新药,已经对有机硒化合物的抗氧化特性进行了广泛研究,因为氧化应激可导致多种慢性人类疾病。在本文中,我们报道了通过简单有效的合成途径合成新的含氮二硒化物。获得的产物的收率高至优异,并且通过NMR和HRMS技术实现了它们的鉴定和表征。新的衍生物可能代表具有不同生物活性的有前途的结构,这些结构可以通过多种作用机理来抵抗氧化应激。新合成化合物的谷胱甘肽过氧化物酶样测定(GPx样活性)表明它们还原了H 2 O 2。牺牲PhSH来浇水。用二硒化物2b可获得最好的结果,二硒化物2b的活性是标准有机硒药物依布硒仑的9倍,相反,该化合物不会被肝TrxR还原。所有这些新化合物均能抑制Fe(II)诱导的TBARS。
