RESUMO
This paper reports the synthesis of tauryl dipeptides related to carnosine. In particular H-Tau-His-OH (5), H-Tau-His(pi-Me)-OH (6) and H-Tau-His(tau-Me)-OH (9) are described. The enzyme carnosinase has been isolated from pig kidney and after purification has been used to test the stability and the inhibitory activity of the three new analogues. H-Tau-His-OH (5) and H-Tau-His(tau-Me)-OH (9) were found to possess weak inhibitory properties towards carnosinase, while H-Tau-His(pi-Me)-OH (6) proved to be devoid of any significant activity. All the three sulfonamido pseudopeptides 5, 6 and 9 show stability to carnosinase activity.
