治疗性多肽靶向中枢神经系统给药的研究进展

Recent advance in new strategies for therapeutic peptide delivery to the central nervous system

随着当今生物技术的迅猛发展,治疗性多肽以其易于设计和高靶向特异性,成为中枢神经系统疾病药物研发的热点,但治疗性多肽很难跨越血脑屏障的阻碍进入中枢神经系统和靶细胞内,加之其在体内的不稳定性,严重制约了其在中枢神经系统疾病中的应用。本文现围绕治疗性多肽透过血脑屏障靶向中枢神经系统给药的研究进展进行综述,对比分析治疗性多肽结合其他分子增加穿透力、特异性和稳定性的方法,以期为靶向中枢神经系统药物的开发提供帮助。

With the rapid development of biotechnology, therapeutic peptide has been a hot area in the central nervous system drugs due to its features of easy to design and target specificity. However, therapeutic peptide is difficult to cross the blood brain barrier into the central nervous system and target cells, coupled with its in vivo instability, which seriously restricts its application in central nervous system diseases. This review focuses on the progress of therapeutic peptides across the blood brain barrier targeting the central nervous system, compares and analyses the methods of increasing therapeutic peptides penetration, specificity and stability in combination with other molecules, in order to provide help for the development of central nervous system drugs.
