Abstract for-d-Met-l-Leu-l-Phe-OMe was synthesized in order to understand the importance of the methionine configuration on human neutrophil biological activity. Our results show that both chemotactic response and lysozyme release are lower than those of the parent fMLP-OMe, indicating that the specific receptor pocket possesses a well-located, restricted positive area that does not completely face
摘要 为了了解蛋氨酸构型对人类中性粒细胞生物活性的重要性,合成了 for-d-Met-l-Leu-l-Phe-OMe。我们的研究结果表明,趋化反应和溶菌酶释放均低于亲本 fMLP-OMe,这表明特定受体口袋具有位置良好、限制性的阳性区域,该区域不完全面对 d-Met 残基。超氧阴离子产生的触发似乎对这种配置变化不敏感。
