Figure 1. Overall scheme for proposed GlcNAc-mediated drug delivery system.
(a) Decoration of drug-loaded polymeric nanoparticle with GlcNAc should provide a mechanism whereby therapeutics may be delivered intracellularly to CMs. (b) The particle will be composed of the acid-labile poly(cyclohexane-1,4-diyl acetone dimethylene ketal) (PCADK). Once internalized, the particle will degrade into the biocompatible products acetone and cyclohexanedimethanol.
