AI Article Synopsis
Article Abstract
The carbosilane metallodendrimer G-[[NCPh(o-N)Ru(η6- p-cymene)Cl]Cl] (CRD13), based on an arene Ru(II) complex coordinated to imino-pyridine surface groups, has been conjugated with anti-cancer drugs. Ruthenium in the positively-charged dendrimer structure allows this nanoparticle to be considered as an anticancer drug carrier, made more efficient because ruthenium has anticancer properties. The ability of CRD13 to form complexes with Doxorubicin (DOX), 5-Fluorouracil (5-Fu), and Methotrexate (MTX) has been evaluated using zeta potential measurement, transmission electron microscopy (TEM) and computer simulation. The results show that it forms stable nanocomplexes with all those drugs, enhancing their effectiveness against MDA-MB-231 cancer cells. In vivo tests indicate that the CRD13/DOX system caused a decrease of tumor weight in mice with triple negative breast cancer. However, the tumors were most visibly reduced when naked dendrimers were injected.

Background: Melanoma is an aggressive skin tumor with limited therapeutic options due to rapid proliferation, early metastasis, and poor prognosis. Baicalin (BA), a natural flavonoid, shows promise in inducing ferroptosis and apoptosis but faces challenges of poor solubility and bioavailability. To address these issues, we developed a multifunctional drug delivery system: manganese-doped ZIF-8 nanoparticles (ZIF(Mn)) loaded with BA and modified with folic acid (FA) and polyethylene glycol (PEG).

Exosomes are vesicles ranging from 30 to 100 nanometers in size that show great potential as carriers for therapeutic uses and drug delivery. Enriching a specific set of miRNAs in exosomes emphasizes the existence of particular sorting mechanisms that manage the targeted cargo packaging. The molecular mechanism for miRNA sorting has not been understood.

Lipid nanoparticles serve as a promising drug delivery system due to the good biocompatibility, non-immunogenicity, and high drug loading efficiency. However, unmodified lipid nanoparticles have limitations such as poor stability, easy hydrolysis, and rapid removal. To overcome these shortcomings, researchers have developed peptide modification, antibody modification, ligand modification, nucleic acid aptamer modification, and polysaccharide modification for lipid nanoparticles.

In order to enrich the selection of biological ligands, realize the miniaturization analysis, and broaden the application of monolith materials for active ingredients screening and separating, we sough to construct a lipid raft @capillary monolith microcolumn affinity chromatography model. Single factor experiments and various characterization methods, including scanning electron microscopy (SEM) and thermogravimetric analysis, were employed to investigate the polymerization of the monolith column under different material ratios to determine optimal preparation conditions. Subsequently, the lipid raft from U251 cells was integrated with the monolith materials based on epoxy-based covalent crosslinking principle and characterized through SEM and immunofluorescence methods.

Acyclovir (ACV) is a potentially effective antiviral medication; however, it has a serious drawback, which is its poor solubility, bioavailability, and short half-life. The goal of this study is to improve its drawbacks through the synthesis of nanogels. In this study, the cross-linked hyaluronic acid-grafted poly(acrylamide--itaconic acid) nanogel is synthesized successfully through free radical polymerization and used as a safe pH-responsive carrier for ACV.
