Peptide drugs have the advantages of target specificity and good drugability and have become one of the most increasingly important hotspots in new drug research in biomedical sciences. However, peptide drugs generally have low bioavailability and metabolic stability, and therefore, the modification of existing peptide drugs for the purpose of improving stability and retaining activity is of viable
多肽药物具有靶点特异性、成药性好等优点,已成为生物医学领域新药研究日益重要的热点之一。然而,肽药物普遍生物利用度和代谢稳定性较低,因此,对现有肽药物进行修饰以提高稳定性和保留活性具有重要意义。众所周知,胰高血糖素是治疗严重低血糖的有效疗法,但其半衰期短阻碍了其广泛的治疗用途。在此,我们报道,组合的非天然残基和长脂肪酸缀合提供了有效的胰高血糖素α/磺基-γ-A肽混合类似物,具有增强的稳定性和延长的体内活性。该策略可用于开发其他短效生物活性肽的稳定类似物。
