of α, β -dehydrophenylalanine on activity and conformation. The analog peptide shows high biological activity in stimulating superoxide production by rabbit neutrophils. An NMR analysis of the solution conformation of the ΔZ-Phe analog, using nuclear Overhauser effects and comparisons with the corresponding saturated peptides, favours a significant population of extended backbone conformations.
合成了趋化三肽的甲酰-Met-Leu- ΔZ -Phe-OMe甲酰-Met-Leu-Phe,以评估α,β-脱氢苯丙氨酸的取代对活性和构象的影响。类似物肽在刺激兔嗜中性粒细胞产生超氧化物方面显示出高的生物学活性。使用核Overhauser效应对ΔZ -Phe类似物的溶液构象进行NMR分析,并与相应的饱和肽进行比较,这有利于大量的扩展骨架构象。
