CEM微波合成用于γ-Lactam的研究

更新時間：2012-06-29 點擊次數(shù)：2708

INTRODUCTION

One challenge facing peptide synthesis is the -lactam formation of arginine （Figure 1）. The formation of -lactam occurs when the internal nitrogen of the guanidine attacks the activated ester, irreversibly forming the lactam ring. This reaction is competitive with peptide-bond formation, greatly reducing the coupling efficiency of arginine.

Figure 1: γ-Lactam Formation

The goal of this study was to determine what effect microwave irradiation has on -lactam formation and how to optimize the microwave synthesis of arginine-containing peptides. As a test substrate, we selected the 1992 ABRF study peptide sequence. This sequence is known to suffer from Arg deletion due to -lactam formation.
