Five ebselen and three acyclic ebselen derivatives were synthesized. These compounds were screened for their glutathione peroxidase (GSH Px)-like activity and scavenging activity against 1,1-diphenyl-2-pycryl-hydrazyl (DPPH) and peroxynitrite radical. All tested compounds displayed similar significant GSH Px-like activity, which are slightly higher than that of ebselen. The peroxynitrite scavenging activity showed that the acyclic allylseleno 4c was five times more potent than ebselen.
合成了五种依布硒和三种无环依布硒衍生物。对这些化合物进行了谷胱甘肽过氧化物酶(GSH Px)样活性和清除 1,1-二苯基-2-吡丙烯基-肼(DPPH)和过氧化亚硝酸自由基活性的筛选。所有测试化合物都显示出类似 GSH Px 的显著活性,且略高于依布硒。过氧化亚硝酸清除活性显示,无环烯丙基硒 4c 的清除活性是依布硒的五倍。
