NADPH is a coenzyme of glutathione reductase (GR), thioredoxin reductase (TrxR) and NADPH oxidase (NOX), and participates in redox reactions as a hydrogen donor. NADPH has the characteristic of selectively participating in the regulation of cellular redox homeostasis. NADPH exerts antioxidant activity and resists reactive oxygen species (ROS) damage by providing reducing equivalents for the regeneration of glutathione (GSH) and thioredoxin (Trx); at the same time, it acts as a substrate of NOX to generate superoxide anions, mediating oxidative stress and immune response. NADPH participates in maintaining the intracellular reducing environment, biosynthesis and regulating gene expression (such as the Nrf2 pathway), and is mainly used in the study of oxidative stress-related diseases (such as cardiovascular diseases, neurodegenerative diseases, cancer) and immune regulation mechanisms .

5β-Cholanic acid is a hydrophobic modifier used to modify polymer carriers. 5β-Cholanic acid can improve the acid stability, cell penetration efficiency and drug sustained release ability of nanocarriers, and optimize the oral effectiveness of delivered molecules. 5β-Cholanic acid can covalently bind to Glycol chitosan (GC) to form a GC-CA conjugate, which optimizes the hydrophobic anchoring ability of nanoparticles and enables them to be stably adsorbed on the surface of PLGA nanoparticles. Such nanoparticles can resist dissociation in the gastric acid environment and maintain positive charge to enhance endocytic uptake by intestinal epithelial cells (such as Caco-2 cells). 5β-Cholanic acid can be used in the development of drug delivery systems .
