Polypept(o)ide-Based Core–Shell Bottlebrush Polymers: A Versatile Platform for Drug Encapsulation Volume 25 Issue 7, 2025

Front Cover: Cylindrical bottlebrush polymers (CBPs) enable precise control over nanoparticle properties via polymer synthesis. Here, a grafting-from approach utilizing a polylysine backbone enabled the formation of amphiphilic polypept(o)ide-based side chains by sequential NCA-ROP, which provides convenient access to core-shell CBPs. These core-shell architectures combine Dasatinib-loading and sustained release kinetics with cellular uptake and therapeutic efficacy in glioblastoma cells. More details can be found in article 2500083 by Heyang Zhang, Matthias Barz, and co-workers.

Polypept(o)ide-Based Core–Shell Bottlebrush Polymers: A Versatile Platform for Drug Encapsulation

This study developed polypept(o)ide-based core–shell brushes (CSBs) with tunable sizes (Rh: 17–70 nm) for hydrophobic drug delivery. CSBs achieved 10% dasatinib loading through ππ interactions, enabling sustained release over 72 h. Notably, CSB-dasatinib complexes showed comparable cell viability reduction to the free drug in U-87 MG cells, demonstrating its potential for advanced cancer therapy.

A Novel Series of Synthetic Heparin-Mimetics–Itaconic Acid-Containing Copolymers for Targeting Tumor Cell Coagulability and Metastasis

Heparin is postulated to possess antitumor properties- beyond its anticoagulative activities in oncology, but disclosure of targeted activities is complicated by heparins structural variabilities as natural glycosaminoglycans. Here, synthetic noncarbohydrate polymers are presented with tuneable structures as heparin mimetics in in-vitro-approaches for metastatic control. Among different polymer series, poly(SS-co-IA) copolymers outperform heparin in blocking heparanase, reducing platelet activation, while minimizing HIT II risk of heparin.
