The present invention relates to prodrug compounds of inhibitors of dipeptidyl peptidase IV (DP IV), which prodrug compounds have the general formula A-B-C, wherein
A is an amino acid,
B is a chemical bond between A and C or is an amino acid, and
C is a stable inhibitor of DP IV.
Such prodrug compounds are used in the treatment of impaired glucose tolerance, glucosuria, hyperlipidaemia, metabolic acidoses, diabetes mellitus, diabetic neuropathy and nephropathy and of sequelae of diabetes mellitus in mammals.

A peptide with C-terminal proline amide is produced by reacting in aqueous solution a protein substrate having C-terminal prolyl-leucine, prolyl-isoleucine, prolyl-valine, or polyl-phenylalanine with carboxypeptidase Y in the presence of amonia. The ammonia is preferably generated by the aqueous reaction of an ammonium salt and an alkali. An example of the peptide product is human calcitonin.
在水溶液中,具有 C 端脯氨酰-亮氨酸、脯氨酰-异亮氨酸、脯氨酰-缬氨酸或多酰基苯丙氨酸的蛋白质底物与羧肽酶 Y 在氨的存在下发生反应,生成具有 C 端脯氨酸酰胺的多肽。 氨最好是由铵盐和碱在水溶液中反应生成的。 多肽产品的一个例子是人降钙素。
