Dendrimer with hyperbranched structure and multivalent surface is regarded as one of the most promising candidates close to the ideal drug delivery systems, but the clinical translation and scale-up production of dendrimer has been hampered significantly by the synthetic difficulties. Therefore, there is considerable scope for the development of novel hyperbranched polymer that can not only address the drawbacks of dendrimer but maintain its advantages. The reversible addition-fragmentation…

One-Pot Synthesis of Dual-Responsive Hyperbranched Polymeric Prodrugs Using an All-in-One Chain Transfer Monomer.

One-pot preparation of dual-responsive hyperbranched polymeric prodrugs (DRHPPs) using an all-in-one chain transfer monomer that integrates a drug molecule with both acidic pH- and reduction-sensitive links offered a highly promising platform for efficient anticancer drug delivery.

Triple Functional AB2 Unit-Modulated Facile Preparation of Bioreducible Hyperbranched Copolymers.

A triple functional AB2 unit, A-SS-B2 chain transfer agent (AB2 CTA), that integrates the merits of both multifunctional agents and highly reactive ABx units was designed and synthesized successfully to include a disulfide bond for reduction-triggered polymer degradation toward promoted intracellular release of encapsulated cargoes.

Long-Chain Hyperbranched Polymers: Synthesis, Properties, and Applications.

A comprehensive summary of the research progress of LCHBPs is presented, with a particular focus on their synthetic strategies, unique properties, and potential applications.

Micelles with cyclic poly(ε-caprolactone) moieties: greater stability, larger drug loading capacity, and slower degradation property for controlled drug release.

The topological effect of a hydrophobic moiety on the properties of the self-assembled micelles is uncovered, and a complementary alternative to enhance the micelle stability by introducing a cyclic hydrophilic segment is developed.

Synthesis of cyclic graft polymeric prodrugs with heterogeneous grafts of hydrophilic OEG and reducibly conjugated CPT for controlled release.

Cg-prodrug-based micelles exhibited greater in vitro cytotoxicity against cancer cells despite the lower drug loading content than the bg-based analogues, which results primarily from the faster reduction-triggered degradation and drug release as well as the greater cellular uptake efficiency of the former micelle prodrugs.
