selenonium, sulfonium, and iminium analogues of salacinol containing polyhydroxylated, monosulfated, extended acyclic chains of 6-carbons, differing in stereochemistry at the stereogenic centers and ring-heteroatom constitution. Four of these compounds inhibit recombinant human maltase glucoamylase, one of the key intestinal enzymes involved in the breakdown of glucose oligosaccharides in the small intestine
合成了六种天然存在的糖苷酶抑制剂salacinol的扩链类似物,具有环杂原子变化,用于使用不同的糖苷酶进行结构活性研究。合成过程涉及PMB保护的d和1-硒代,硫代和亚氨基阿拉伯糖醇与亚苄基和异亚丙基保护的1,3-环硫酸盐的反应,该硫酸盐可从市售d衍生而来。-山梨糖醇,含碳酸钾的1,1,1,3,3,3-六氟-2-丙醇。产物的脱保护提供了含有六羟基碳的多羟基化,单硫酸化,延伸的无环链的水杨醇的新型硒代,sulf和亚胺类似物,其立体化学在立体中心和环杂原子组成上不同。这些化合物中的四种抑制重组人麦芽糖酶葡糖淀粉酶,后者是参与小肠中葡萄糖寡糖分解的关键肠酶之一,K i值在微摩尔范围内,因此为治疗2型糖尿病提供了主要候选药物。
