DOCUMENT TYPE: Journal CA Section: 34 (Synthesis of Amino Acids, Peptides, and Proteins) Section cross-reference(s): 25, 63 The title derivs. 121-02-8 is also in the experiment. I, II, an III (X = Gly, Ala, Val, Leu, DL-Phe, Tyr, DL-Pro; R = OH) were prepd. by acylating the appropriate amino acid with the appropriate benzenesulfonyl chloride. Dipeptides I (X = Gly-Gly, Tyr-Leu; R = Me) were prepd. by coupling I (X = Gly, Tyr; R = OH) to the appropriate amino acid Me ester by dicyclohexylcarbodiimide. II (X = DL-Phe-Gly, Tyr-Tyr; R = Me) and III (X = Gly-Gly, Leu-Leu; R = Me) were also prepd. Some of the above derivs. exhibited antibacterial activity. ..
