L-DMDP, prepared from D-gulonolactone, is a highly specific inhibitor of a number of plant and mammalian alpha-glucosidases [between 2 and 4 orders of magnitude more potent than the enantiomeric natural product DMDP] but is not an inhibitor of bacterial and yeast alpha-glucosidases. Additionally N-butyl-DMDP is a potent inhibitor of ceramide-specific glucosyltransferase but N-butyl-L-DMDP shows no inhibition.
由D-古洛糖酸内酯制备的L-DMDP是多种植物和哺乳动物α-葡萄糖苷酶的高度特异性抑制剂[比对映体天然产物DMDP的效力高2至4个数量级],但不是细菌和酵母α-葡萄糖苷酶的抑制剂。此外,N-丁基-DMDP是神经酰胺特异性葡萄糖基转移酶的有效抑制剂,但N-丁基-L-DMDP没有抑制作用。
