Research Progress of Targeted Drug Delivery Nanocarriers Through Blood-brain Barrier / 中国实验方剂学杂志

ABSTRACT

The small size， moderate drug loading， and targeting properties of nano-preparations make them can be excellent delivery tools for drugs， genes or proteins crossing the cell or blood-brain barrier （BBB）. Currently， facilitating drug crossing BBB with innovative nano-drug delivery systems is considered as a strategic approach for the prevention， diagnosis and treatment of central nervous system （CNS） diseases. However， with the deepening of the research， the adverse reactions and toxicity of nanocarriers have gradually attracted the attention of researchers. Based on this， this paper summarized the situation of BBB-penetrating targeted nano-preparations at home and abroad in recent years from the perspective of classification of types and properties of nanocarriers， and analyzed the advantages and disadvantages of each carrier. The results showed that nano-preparations with active ingredients of traditional Chinese medicine （TCM） as carriers have become a promising way of cancer treatment， but the complexity and diversity of TCM components limited its application to a certain extent. Further studies should be strengthened to lay a foundation for the application and development of TCM nano-preparations in the field of CNS diseases.
