5β-Cholanic acid

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[1][2].
