Peptide derivatives related to the active site of some hydrolytic enzymes: I. Syntheses of tetrapeptide ethyl esters containing glutamic acid and serine

Autor: J. P. J. van der Holst, A. van De Linde, A. Verweij, H. Kienhuis

Publikováno v: Recueil des Travaux Chimiques des Pays-Bas. 80:1278-1284

The syntheses of glycyl-α-L-glutamyl-L-serylglycine ethyl ester and of glycyl-α-L-glutamyl-O-acetyl-L-serylglycine ethyl ester are described. The mixed anhydride method and the carbodiimide method were used for condensing together two dipeptide der

Intramolecular catalysis in cis-diethyl 2-carboxyvinylphosphonate hydrolysis

Autor: H. Kienhuis, J. P. J. van der Holst, C. van Hooidonk

Publikováno v: Recueil des Travaux Chimiques des Pays-Bas. 93:40-43

The hydrolysis of the title compound proceeds very fast in weakly acidic aqueous media by a stepwise release of both ethyl ester groups via phosphorus-oxygen bond fission. The reactions are about 106 times faster than that for the release of one ethy

Peptide derivatives related to the active site of some hydrolytic enzymes III. Syntheses and some physical properties of tetrapeptide derivatives protected by N-acetyl and amide groups

Autor: A. Verweij, J. P. J. van der Holst, H. Kienhuis

Publikováno v: Recueil des Travaux Chimiques des Pays-Bas. 83:1129-1141

For our investigations of model compounds related to the active site of esterases some new peptide derivatives containing the amino acid sequences gly-asp-ser-gly, gly-glu-ser-gly and gly-gly-ser-gly were synthesized. The compounds were obtained by c

Peptide derivatives related to the active site of some hydrolytic enzymes: IV. Tetrapeptide derivatives containing D-serine

Autor: A. Verweij, H. Kienhuis, J. P. J. van der Holst

Publikováno v: Recueil des Travaux Chimiques des Pays-Bas. 88:592-596

The syntheses of derivatives of the L-L tetrapeptides Gly-Asp-Ser-Gly and Gly-Glu-Ser-Gly have been described in preceding communications 123 . These compounds were used as models for esterases. In order to study the effects of configuration and conf
