DL-phenyl-aminobutyric acid amide were resolved to L-amino acids and D-amino acid amides by the partially purified leucine aminopeptidase preparation. The products in the digests were separated conveniently by the use of ion-exchange resin, Amberlite IRA-400, in the case of DL-phenylalaninamide, while by the differential solubility in the case of DL-phenylaminobutyric acid amide. The parts of D-amino acid amide hydrochlorides
DL-苯丙酰胺和DL-苯基-氨基丁酸酰胺通过部分纯化的亮氨酸氨肽酶制剂拆分为L-氨基酸和D-氨基酸酰胺。对于 DL-苯丙酰胺,使用离子交换树脂 Amberlite IRA-400 可以方便地分离消化物中的产物,而对于 DL-苯氨基丁酰胺,则使用不同的溶解度。得到的D-氨基酸酰胺盐酸盐部分经酸水解转化为D-氨基酸。
