A Sensitive Fluorometric Assay for Activity of Pepsin
Fluorogenic substrates of pepsin; Dns-Ala-Ala-Phe-Trp-Val-Leu-OCH2Py (I), Ala-Ala-Trp-Phe-Leu-NHNHDns (II), and Ala-Ala-Trp-Phe-NHNHDns (III) were synthesized by a solution method and their properties were compared with Dns-Ala-Phe-Trp-Val-Leu-OCH2Py (IV)
