A novel lipophilic glyoxylic acid derivative for the lipidation of peptides using salt-free hydrazone ligation
摘要:
A lipophilic vector, composed of a palmitoyl and glyoxylyl group linked by a 1,3-diaminopropane moiety, was found to react rapidly and almost quantitatively with N-terminal alpha -hydrazino acetyl peptides to give the corresponding hydrazones. The ligation was performed in salt-free conditions, using a 95/5 mixture of 2-methyl-propan-2-ol/water. (C) 2000 Elsevier Science Ltd. All rights reserved.
