Amino Acids and Peptides. XXVIII. Preparation of Poly(Ethylene Glycol)Hybrids of Gln-Val-Val-Ala-Gly Analogs and Their Inhibitory Effect on Papain

抄録

Gln-Val-Val-Ala-Gly is a sequence which is common in cystetine protease inhibitors. Poly(ethylene glycol)hybrids of Gln-Val-Val-Ala-Gly analogs were prepared by the solid phase method by fluorenylmethyloxycarbonyl chemistry. The hybrid formation of Gln-Val-Val-Ala-Gly resulted in improvement of the solubility and also in enhancement of the inhibitory effect of the peptide on papain. In addition, the hybrid formation of Gln-Val-Val-Ala-Gly analogs resulted in the enhancement of the inhibitory effect of the peptide analogs.
