Rotaxane-Based Propeptides: Protection and Enzymatic Release of a Bioactive Pentapeptide

摘要

Rotaxane and pseudorotaxane architectures are starting to attract interest as a means of molecularly encapsulating substrates for potential biological applications.Nano-valves' that can store and release cargo molecules have been developed, and the encapsulation of squaraine dyes within rotaxanes has been shown to enhance dye fluorescence and stability as well as imparting different cell-localization propensities on the substrates.
