Polymer-assisted solution-phase parallel synthesis of dipeptide p-nitroanilides and dipeptide diphenyl phosphonates
摘要:
This letter describes the parallel synthesis of dipeptide p-nitroanilides (1) and dipeptide diphenyl phosphonates (2). compounds that can be used as Substrates and irreversible inhibitors for the rapid profiling of dipeptidyl peptidases. A polymer-assisted solution-phase synthesis was used for a rapid and clean Coupling between easily available building blocks. (C) 2001 Elsevier Science Ltd. All rights reserved.
Atlantic cod trypsin-catalyzedpeptidesynthesis has been studied by using p-amidino- and p-guanidinophenyl esters of N-(tert-butyloxycarbonyl)amino acid as acyl donor components. The reaction temperature was optimized at 0 degrees C. The method was shown to be successful as effectively for synthesizing the peptide and useful for preparing dipeptide between D-amino acid with D-amino acid and beta-amino
Trypsin-catalyzedpeptidesynthesis has been studied by using p-guanidinophenyl esters of N alpha-(tert-butyloxycarbonyl)amino acid and peptide as acyl donor components. The reaction conditions were optimized for organic solvents, pH, and concentration of acceptor. The method was especially useful for the preparation of various peptides containing D-amino acids. The enzymatic hydrolysis of the resulting
Methyltrypsin-catalyzed peptide synthesis has been studied by using conventional alkyl ester and p-guanidinophenyl ester derivatives of alpha-amino acid as the acyl donor component. They were found to be coupled with alpha-amino acid derivatives (acyl acceptor component) to produce dipeptide. The behavior of methyltrypsin toward both the substrates has been studied.
