The relative simplicity and high specificity of peptide therapeutics has fueled recent interest. However, peptide and protein drugs generally require injection and suffer from low metabolic stability. We report here the design, synthesis, and characterization of fluorinated analogues of the gut hormone peptide, GLP-1. Overall, fluorinated GLP-1 analogues displayed higher proteolytic stability with simultaneous retention of biological activity (efficacy). Fluorinated amino acids are useful for engineering peptide drug candidates and probing ligand-receptor interactions.
肽类疗法相对简单且特异性高,这引发了近期的关注。然而,肽类和蛋白质药物通常需要注射给药,并且代谢稳定性较低。我们在此报告肠道激素肽GLP - 1的氟化类似物的设计、合成及表征。总体而言,氟化GLP - 1类似物表现出更高的蛋白水解稳定性,同时保留了生物活性(功效)。氟化氨基酸可用于构建肽类药物候选物以及探究配体 - 受体相互作用。
