The synthesis of the enantiomers of 6-epicastanospermine and of 1,6-diepicastanospermine from the enantiomeric gulonolactones is reported and the structure of the former is established as (1S,6R,7R,8R,8aR)-1,6,7,8-tetrahydroxyoctahydroindolizine. The inhibitory activities of the diastereomers against the amyloglucosidase-catalysed hydrolysis of p-nitrophenyl alpha-D-glucopyranoside were investigated
据报道,由对映体古洛内酯合成6-表锡精胺和1,6-二硬脂精胺的对映异构体,前者的结构确定为(1S,6R,7R,8R,8aR)-1,6,7,8 -四羟基八氢吲哚嗪。研究了非对映异构体对淀粉葡糖苷酶催化的对硝基苯基α-D-葡萄糖吡喃糖苷水解的抑制活性,并报道了6-表二十碳四烯精胺和1,6-二甲基吡喃二精胺对14种人肝糖苷酶的影响。
