Synthesis and screening of peptoid arrays on cellulose membranes
摘要:
Rapid synthesis and screening of compound libraries enables the accelerated identification of novel protein ligands in order to support processes like analysis of protein interactions, drug target discovery or lead structure discovery. SPOT synthesis-a well established method for the rapid preparation of peptide arrays-has recently been extended to the field of nonpeptides. In this contribution we report on the systematic evaluation of the SPOT technique for the assembly of N-alkylglycine (peptoid) library arrays. In the course of this investigation bromoacetic acid 2,4-dinitrophenylester (1a) was identified to be the most suited agent for bromoacetylation in terms of yield and N-selectivity enabling straightforward submonomer synthesis on hydroxy-group rich cellulose membranes. The potential of this method for the rapid identification of novel nonpeptidic protein ligands was demonstrated by synthesis and screening of a library consisting of 8000 peptoids and peptomers (i.e. their hybrids with a-substituted amino acids) allowing the identification of micromolar ligands for the monoclonal antibody Tab-2.

The SPOT synthesis technique, originally developed for peptide synthesis on cellulose membranes, was successfully adapted for the modular, parallel synthesis of 1,3,5-trisubstituted hydantoins. The synthetic approach presented here is based on a modified sub-monomer peptoid synthesis protocol on cellulose membranes. (C) 2000 Published by Elsevier Science Ltd.

With microwave irradiation, the submonomer synthesis of dipeptoids on functionalized cellulose can be accelerated with good yields and purity. Optimization provided a library of 96 dipeptoids. From these, 29 compounds were found with an antibacterial activity against MRSA at a concentration of 25 mu M. Large nonpolar residues, such as undecylamine and dehydroabiethylamine, are the key components engendering the observed antibacterial activity of these peptoids.
