investigation its mechanism of action, we designed and synthesized its biotinylated derivative 2 as a novel probe. From commercially available starting material, 2 was obtained in 6 steps with 13.4% overall yield. It is notable that this practical synthetic route give a template for the preparation of unsymmetrical di-benzo[d][1,2]selenazol-3(2H)-ones. Based on probe 2, we developed a novel biomolecular
Hexylselen是一种新型的亚微摩尔双KGA / GDH抑制剂,可有效抑制癌细胞,并具有最小的毒性。为了进一步研究其作用机理,我们设计并合成了其生物素化衍生物2作为新型探针。从市售原料中,经6个步骤得到2个,总收率为13.4%。值得注意的是,该实用的合成途径为制备不对称的二苯并[ d ] [1,2]硒烯唑-3(2 H)-酮提供了模板。基于探针2,我们开发了一种新颖的生物分子相互作用测定法,用于方便,可靠地测试KGA变构抑制剂,并通过竞争性实验证实,己基硒醚作为KGA的变构抑制剂,与BPTES具有相同的结合口袋,而与Ebselen没有相同的结合口袋。
