Abstract
Coacervation driven liquid-liquid phase separation of biopolymers has aroused considerable attention for diverse applications, especially for the construction of microstructured polymeric materials. Herein, a coacervate-to-hydrogel transition strategy is developed to create macroporous hydrogels (MPH), which are formed via the coacervation process of supramolecular assemblies (SA) built by the host-guest complexation between γ-cyclodextrin and anthracene dimer. The weak and reversible supramolecular crosslinks endow the SA with liquid-like rheological properties, which facilitate the formation of SA-derived macroporous coacervates and the subsequent transition to MPH (pore size ≈ 100 µm). The excellent structural dynamics (derived from SA) and the cytocompatible void-forming process of MPH can better accommodate the dramatic volumetric expansion associated with colony growth of encapsulated multicellular spheroids compared with the non-porous static hydrogel with similar initial mechanical properties. The findings of this work not only provide valuable guidance to the design of biomaterials with self-evolving structures but also present a promising strategy for 3D multicellular spheroid culture and other diverse biomedical applications.

Abstract
The efficiency of reactive oxygen species (ROS)-based photodynamic therapy (PDT) is far from satisfactory, because cancer cells can adapt to PDT by upregulating glutathione (GSH) levels. The GSH levels in tumor cells are determined based on glutamine availability via alanine-serine-cysteine transporter 2 (ASCT2)-mediated entry into cells. Herein, we develop co-assembled nanoparticles (PPa/V-9302 NPs) of the photosensitizer pyropheophorbide a (PPa) and V-9302 (a known inhibitor of ASCT2) in a 1:1 M ratio using a one-step precipitation method to auto-enhance photodynamic therapy. The computational simulations revealed that PPa and V-9302 could self-assemble through different driving forces, such as π-π stacking, hydrophobic interactions, and ionic bonds. Such PPa/V-9302 NPs could disrupt the intracellular redox homeostasis due to enhanced ROS production via PPa-induced PDT and reduced GSH synthesis via inhibition of the ASCT2-mediated glutamine flux by V-9302. The in vivo assays reveal that PPa/V-9302 NPs could increase the drug accumulation in tumor sites and suppress tumor growth in BALB/c mice bearing mouse breast carcinoma (4 T1) tumor. Our findings provide a new paradigm for the rational design of the PDT-based combinational cancer therapy.

Interfacial Behavior of Oligo(Ethylene Glycol) Dendrons Spread Alone and in Combination with a Phospholipid as Langmuir Monolayers at the Air/Water Interface. Molecules 2019; 24:E4114. [PMID: 31739495 PMCID: PMC6891365 DOI: 10.3390/molecules24224114] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2019] [Revised: 11/09/2019] [Accepted: 11/11/2019] [Indexed: 01/11/2023] Open
Abstract
Dendrons consisting of two phosphonate functions and three oligo(ethylene glycol) (OEG) chains grafted on a central phenoxyethylcarbamoylphenoxy group were synthesized and investigated as Langmuir monolayers at the surface of water. The OEG chain in the para position was grafted with a t-Bu end-group, a hydrocarbon chain, or a partially fluorinated chain. These dendrons are models of structurally related OEG dendrons that were found to significantly improve the stability of aqueous dispersions of iron oxide nanoparticles when grafted on their surface. Compression isotherms showed that all OEG dendrons formed liquid-expanded Langmuir monolayers at large molecular areas. Further compression led to a transition ascribed to the solubilization of the OEG chains in the aqueous phase. Brewster angle microscopy (BAM) provided evidence that the dendrons fitted with hydrocarbon chains formed liquid-expanded monolayers throughout compression, whilst those fitted with fluorinated end-groups formed crystalline-like domains, even at large molecular areas. Dimyristoylphosphatidylcholine and dendron molecules were partially miscible in monolayers. The deviations to ideality were larger for the dendrons fitted with a fluorocarbon end-group chain than for those fitted with a hydrocarbon chain. Brewster angle microscopy and atomic force microscopy supported the view that the dendrons were ejected from the phospholipid monolayer during the OEG conformational transition and formed crystalline domains on the surface of the monolayer.
