Endogenous Enzyme-responsive Nanoplatforms for Anti-tumor Therapy.

Abstract:

:The emergency of responsive drug delivery systems has contributed to the reduced cytotoxicity, the improved permeability in tissues and extended circulation time of the active drug. Of particular, enzyme-responsive nanoplatforms have attracted a lot due to the specificity and efficiency of an enzyme-catalyzed reaction. In this review, enzyme-based mono responsive drug delivery systems designed in the past 5 years were summarized. These drug delivery systems were introduced by different tumor-related enzymes such as matrix metalloproteinase, esterase, hyaluronidase, caspase and cathepsin. Moreover, the enzyme-sensitive nanoplatforms activated by dual-stimuli were also described. Although great progress had been made in the past years, the translation into clinical practice was still difficult. Thus, three obstacles (enzyme heterogeneity, reaction environment, animal model) were also discussed. In short, enzymeactivated drug delivery systems offer great potential in treating cancers.
