Summary: In this study, we synthesized polyethylenimine2k (PEI2k)-conjugated hydroxyethyl cellulose (HECP2k) for the co-delivery of doxorubicin/Bcl-2 siRNA. HECP2ks were successfully synthesized and characterized. The results showed that HECP2ks effectively condensed pDNA into positively charged and nano-sized complexes, exhibiting low cytotoxicity and high transfection efficiency. HECP2k 10X demonstrated superior cellular uptake, endosome escape, and synergistic anti-cancer effects through co-delivery of Dox and Bcl-2 siRNA. Therefore, HECP2k shows great potential as a promising co-delivery carrier for Dox/Bcl-2 siRNA.

Summary: Polysaccharide-based Schiff base hydrogels prepared by reacting oxidized hydroxypropyl cellulose (Ox-HPC) with carboxymethyl chitosan (CMCS) exhibit pH-responsive, injectable, and self-healing properties. The reversible nature of the imine bonds allows for an injectable and self-healing hydrogel. The incorporation of the model amine-containing drug phenylalanine within the hydrogel showed pH sensitivity, releasing faster in the extracellular space around tumors (pH 6.8) compared to normal tissues (pH 7.4).

Summary: In this study, a novel green synthesis route was described for the growth of metal-organic framework (MOF) from zinc metal and 1,4-benzene dicarboxylic acid in the presence of carboxymethyl cellulose (CMC). The synthesized material showed promising characteristics for prolonged drug release, with high drug loading efficiency and better drug release performance compared to the pristine MOF. Overall, the results confirm the functionality of CMC biopolymer for in situ growth of MOF and its cytocompatibility.

Summary: A pH-sensitive nanocomposite was synthesized by coating halloysite nanotubes (HNT) with polyacrylic acid (PAA)/carboxymethyl cellulose (CMC) hydrogel for controlled delivery of curcumin (CUR) to MCF-7 cancer cells. Hazelnut oil and Span 80 surfactant were added to minimize the nanocomposite size and increase its uniformity, and to enhance the stability and retention of CUR as an anticancer drug, respectively. The resulting drug delivery system exhibited high drug loading and encapsulation efficiency, pH-sensitivity, and sustained drug release. It also demonstrated strong toxicity against MCF-7 cancer cells and induced apoptosis. These results highlight the potential of PAA/CMC/HNT/CUR hydrogel nanocomposites as smart drug delivery vehicles for breast cancer treatment.

Summary: Our previous work demonstrated that beta-lactoglobulin-stabilized amorphous solid dispersion (ASD) loaded with 70 % indomethacin remains stable for over 12 months. We further investigated the stabilization mechanisms by testing five other drug molecules and using experimental techniques and molecular dynamics simulations. The results showed that steric confinement, hydrogen bonding, and the glass transition temperature of the drug molecule play important roles in stabilizing ASDs with high drug loadings.

Summary: The binding of drugs to plasma proteins, such as human serum albumin (HSA), is crucial for determining pharmacokinetic parameters. This study investigated the enantioselective binding of S- and R-ketamine to HSA. It was found that ketamine has weak affinity to HSA, with no significant differences in binding behavior between the individual enantiomers and the racemate. The aromatic ring and N-methyl group were identified as the most strongly involved structural moieties in the binding of ketamine to HSA.

Summary: Interleukins (ILs) are important for communication between immune cells and non-immune cells, but dysregulation of ILs expression is a characteristic of autoinflammatory diseases. Drugs targeting ILs have significant clinical benefits, but may also cause adverse reactions. Fusion protein technology, with its ability to enhance therapeutic efficacy, has been explored for developing anti-inflammatory drugs. This review discusses the efficacy of fusion protein drugs developed with ILs or their receptors in treating autoinflammatory diseases, highlighting the potential of this technology in future anti-inflammatory drug development.

Summary: This study investigated the correlation between the structure and release properties of solid lipid microparticles (MPs) with different liquid additives. The additives accelerated the conversion of the unstable alpha-form of tristearin to the stable beta-polymorph and caused structural modifications in the MPs. The presence of additives prolonged the drug release in water and resulted in higher release profiles in biorelevant media. The findings suggest that the release behavior can be influenced by the polymorphism and supramolecular-level structural modification of lipid formulations containing crystal modifiers.
