用途
DL-丙氨酸乙酯盐酸盐可用作维生素B6的中间体。
生产方法
通过酯化反应制备而成。将无水乙醇和α-丙氨酸投入反应锅中,在室温下通入干燥氯化氢气体直至饱和,待反应液完全澄清后,升温回流4小时。蒸去过量的乙醇至干即得DL-丙氨酸乙酯盐酸盐。
Synthesis and aldose reductase inhibitory profile of certain parabanic acid derivatives 1a-p is described. Also, the antihyperglycaemic potential of these compounds was studied. The most active inhibitors in this series were compounds 1g, 1p, and 10 which showed inhibitory activity, 36.6,90 and 91% respectively, at concentration 1 x 1 0−4. Their IC50 were 2 x 10−6, 7.5 x 1 0-8 and 5 x 10-8, respectively. Compound 10 exhibited pronounced antihyperglycaemic effect.
