Abstract
Due to its simplicity,high efficiency,and chemo-selectivity,bioorthogonal chemistry has shown a great application potential in pre-targeting.Currently,four bioorthogonal pairs as targeting tools,including(strept)avidin/biotin,antibody/antigen,oligonucleotide hybridization and IEDDA tools,have been devel-oped and applied in targeted delivery.Nevertheless,all of these tools still suffer from some limitations,such as difficult modification,biochemical fragility and larger molecular weight for biological associa-tion tools,as well as chemical instability for IEDDA tools.Synthetic host-guest pairs with relatively small molecular sizes not only possess strong chemical stability,but also have the features of fast conjugation rate,tunable binding affinity,easy modification,and high chemo-selectivity.Consequently,they can be used as a novel non-covalent bioorthogonal tool for pre-targeting.In order to further promote the de-velopment of host-guest pairs as novel bioorthogonal tools for pre-targeted delivery,we firstly calculate their conversion rate to make researcher aware of their unique advantages;next,we summarize the re-cent research progress in this area.The future perspectives and limitations of these unique tools will be discussed.This review will provide a systemic overview of the development of synthetic host-guest pairs as novel bioorthogonal tools for pre-targeting,and may serve as a"go for"resort for researchers who are interested in searching for new synthetic tools to improve pre-targeting.
