Boc-Tyr-Gly-Gly-Phe-Leu-Ch2Cl was synthesized by the conventional solution method. During the course of acid hydrolysis (6N HCl, 110 degrees C, 18h) of Boc-Phe-Leu-CH2Cl, side reaction occurred, resulting in low recovery of Phe residue on amino acid analysis. The inhibitory activity of the synthesized Boc-Tyr-Gly-Gly-Phe-Leu-CH2Cl against endopeptidase 22.19, an enzyme related to the metabolism of
