Aggregation-induced emissive materials are gaining particular attention in the last decades due to their wide application in different fields, from optical devices to biomedicine. In this work, compounds having these kinds of properties, composed of tetraphenylethylene scaffold combined with fatty acids of different lengths, were synthesized and characterized. These molecules were found able to self-assemble into different supramolecular emissive structures depending on the chemical composition and water content. Furthermore, they were used as - capping agents in the development of peptide-based materials. The functionalization of a 5-mer laminin-derived peptide led to the obtainment of luminescent fibrillary materials that were not cytotoxic and were able to form supramolecular gels in aqueous environment.

In situ forming gels as subcutaneous delivery systems of curcumin and piperine.

Sci Rep

January 2025

Department of Chemical, Pharmaceutical and Agricultural Sciences, University of Ferrara, I-44121, Ferrara, Italy.

In this study an in situ forming gel for curcumin and piperine delivery is investigated as a long-lasting strategy in the local treatment of inflammatory and degenerative joint disease, such as osteoarthritis and rheumatoid arthritis. Particularly glyceryl monooleate, in association with phosphatidylcholine and ethanol, were employed. Different ratios between excipients were tested, with the aim to obtain a liquid form suitable for subcutaneous injection, gaining a semisolid consistency in contact with biological fluids.

Peptides can be designed to self-assemble into predefined supramolecular nanostructures, which are then employed as biomaterials in a range of applications, including tissue engineering, drug delivery, and vaccination. However, current self-assembling peptide (SAP) hydrogels exhibit inadequate self-healing capacities and necessitate the use of sophisticated printing apparatus, rendering them unsuitable for 3D printing under physiological conditions. Here, we report a precisely designed charged peptide, Z5, with the object of investigating the impact of electrostatic interactions on the self-assembly and the rheological properties of the resulting hydrogels.

In this present study, we developed and characterized a series of supramolecular G4 hydrogels by integrating -cyclodextrin (-CD) and boronic acid linkers into a supramolecular matrix to enhance antibacterial activity against (). We systematically investigated how varying the number of free boronic acid moieties (ranging from two to six), along with guanosine and β-CD content, influences both the structural integrity and antimicrobial efficacy of these materials. Comprehensive characterization using FTIR, circular dichroism, X-ray diffraction, SEM, AFM, and rheological measurements confirmed successful synthesis and revealed that higher boronic acid content correlated with a stronger, more organized network.

Columnar Mesophases and Organogels Formed by H-Bound Dimers Based on 3,6-Terminally Difunctionalized Triphenylenes.

Gels

December 2024

Departamento de Química Inorgánica, Analítica y Química Física, Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, Buenos Aires C1428EGA, Argentina.

A series of triphenylene (TP) compounds-denoted 3,6-THTP-DiCOH-bearing four hexyloxy ancillary chains and two variable-length alkoxy chains terminally functionalized with hydroxyl groups have been synthesized and characterized. The shorter homologs revealed mesogenic characteristics, giving rise to thermotropic mesophases in which π-stacked columns of H-bound dimers self-organize yielding superstructures. Molecular-scale models are proposed to account for their structural features.

A novel isopthalamide based receptor HL2 featuring two p-benzoic acid units has been synthesised and its anion binding properties analysed by H-NMR spectroscopy in DMSO-d/0.5 % HO. As expected, in the presence of tetrabutylammonium (TBA) fluoride the deprotonation of the carboxylic acid moieties was observed.
