Background: Blood-brain permeability is the primary concern when dealing with the biodistribution of drugs to the brain in neurological diseases.
Objective: The purpose of the study is to develop the nanoformulation of Epigallocatechin gallate (EGCG) in order to improve its bioavailability and penetration into the brain.
Methods: EGCG loaded Solid Lipid Nanoparticles (SLNs) have been developed using microemulsification method and pharmacological assessments were performed.
Results: Surface morphology and micromeritics analysis showed the successful development of EGCG loaded solid lipid nanoparticles with an average size of 162.4 nm and spherical in shape. In vitro release studies indicated a consistent and slow drug release. Pharmacological evaluation of SLN-EGCG demonstrated a significant improvement in cerebral ischemia-induced memory impairment.
Conclusion: The results indicate that the EGCG loaded SLNs provide a potential drug delivery system for improved delivery of EGCG to the brain, hence, enhancing its brain bioavailability.

The study investigates the development and characterization of dual-loaded niosomes incorporated into ion-sensitive in situ gel as a potential drug delivery platform for ophthalmic application. Cannabidiol (CBD) and epigallocatechin-3-gallate (EGCG) simultaneously loaded niosomes were prepared via the thin film hydration (TFH) method followed by pulsatile sonication and were subjected to comprehensive physicochemical evaluation. The optimal composition was included in a gellan gum-based in situ gel, and the antimicrobial activity, in vitro toxicity in a suitable corneal epithelial model (HaCaT cell line), and antioxidant potential of the hybrid system were further assessed.

Anthracycline doxorubicin (DOX) remains the first-line chemotherapeutic drug for the efficient treatment of breast cancer, but its severe cardiotoxicity limits its long-term application in clinical tumor chemotherapy. Until now, the pathogenesis mechanism of DOX-induced cardiotoxicity (DIC) is still not fully understood. According to current studies, the oxidative stress caused by the imbalance of reactive oxygen species (ROS) and reactive nitrogen species (RNS) production and mitochondrial dysfunction in myocardial cells are closely related to DIC.

Magnesium (Mg)-based alloys have been recognized as desirable biodegradable materials for orthopedic implants. However, their clinical application has been limited by rapid degradation rates, insufficient antibacterial and osteogenic-promotion properties. Herein, a MgF priming layer was first constructed on AZ31 surface.

Epigallocatechin gallate (EGCG), an important active component extracted from green tea, has attracted much attention due to its multiple biological activities such as antioxidant, antibacterial, anti-inflammatory, and antitumor effects. Meanwhile, metformin (Met), a classic drug for the treatment of type 2 diabetes, exhibits additional benefits such as hypoglycemic, antioxidant, anti-inflammatory, and antitumor effects. However, metformin often causes gastrointestinal reactions when used alone, affecting patients' quality of life.

We aimed at investigating the effect of different anionic polysaccharides (pectin, carboxymethylcellulose, and gum Arabic) on the physicochemical properties and stability of whey protein isolate (WPI)- stabilized solid-in-oil-in-water (S/O/W) bilayer emulsions loaded with epigallocatechin gallate (EGCG). S/O/W emulsions were prepared by homogenizing EGCG-loaded oil with an aqueous phase containing WPI and the selected polysaccharides. The emulsions were characterized for their particle size, zeta potential, microstructure, and rheological properties.
