K. Augustyns et al., SYNTHESIS OF PEPTIDYL ACETALS AS INHIBITORS OF PROLYL ENDOPEPTIDASE, Bioorganic & medicinal chemistry letters, 5(12), 1995, pp. 1265-1270
Several acyclic and cyclic dipeptidyl acetals were synthesized. Among
these, N-[N-benzyloxycarbonyl-(S)-prolyl]-(S)-prolinal dimethyl acetal
8 was shown to be a potent inhibitor of prolyl endopeptidase.
