double nucleophilic displacement of a dimesylated derivative with selenide anion generated in situ. Se-Alkylation and oxidation of the corresponding selenane afforded a selenonium and a selenoxide, respectively. The biological activities of such compounds have been evaluated, finding a dual activity caused by the presence of the selenium atom: the selenane exerted a good glutathione peroxidase mimicry
通过用原位产生的硒化阴离子对二甲基化衍生物进行双亲核置换,可以合成一系列1 -fuco-构型的硒代糖,即有效的糖苷酶抑制剂异氟卡因的等排体。相应的硒烷的Se-烷基化和氧化分别提供了硒鎓和硒氧化物。已评估了此类化合物的生物活性,发现了硒原子的存在引起的双重活性:硒烷通过在硫醇的存在下有效清除H 2 O 2,发挥了良好的谷胱甘肽过氧化物酶模拟作用,而稳定的硒氧化物衍生物为被发现是硒糖起良好α- 1作用的第一个例子-岩藻糖苷酶抑制剂。
