by heating in dilute nitric acid. The lactone, formed by heat dehydration from aqueous solution at low pH, was purified by paper chromatography, and quantitated by gas-liquid chromatography using inositol as the internal standard. The monolactone inhibited human, seminal-fluid α- l -idosiduronase activity, with either phenyl or 4-methylumbelliferyl α- l -idosiduronic acid as the substrate, to the same
摘要1-Idaro-1,4-内酯是通过两种不同的已公开方法合成的:(1)通过在氢氧化钡水溶液中回流,使葡萄糖酸单钾盐差向异构化;(2)通过在稀硝酸中加热而氧化1-糖醇。由低pH值的水溶液加热脱水而形成的内酯通过纸色谱法纯化,并使用肌醇作为内标通过气液色谱法定量。单苯内酯以苯基或4-甲基伞形酮基α-1-多聚异丁二糖醛酸为底物抑制人精液α-1-异十二烷醛酸酶活性,其抑制程度与d-葡萄糖醛-1,4-内酯抑制α-d相同。 -葡萄糖苷酸酶。
