Medicines containing an N-acyl-L-aspactyl-taurine.

摘要

Dipeptide derivatives represented by the general formula Ac - A - X - Y, wherein Ac represents the acyl rest of an organic carboxylic acid. A is an amino acid carrying a carboxylic function at alpha . X is an amino acid rest and Y is hydrogen or the rest of a mono- or disubstituted amine. They are prepared by acetylation of the amino acid A and then by dihydration of the N-acetyl amino acid into anhydride, coupling with an X amino acid, new dihydration of the dipeptide N-acetyl A-X into anhydride-amide and condensation with a Y amine to form the dipeptide Ac - A - X - Y.
