Nanotechnology-based approaches have enabled overcoming the challenging issues such as the rapid clearance, poor solubility, and non-specific action or cellular uptake of drugs. In this study, we have evaluated the therapeutic effects of the phenolic compound, ferulic acid (FA), in the acute pancreatitis (AP) as this phenolic compound has demonstrated promising effects against the oxidative stress and inflammatory reactions. In order to overcome the poor solubility and bioavailability of FA, it was entrapped into the nanoparticles (NPs) based on the silk fibroin (SF) as a biomimetic substance. Neutrophil membrane-coated SF-NPs with appropriate capacity of FA loading and physicochemical characteristics, released FA in a controlled fashion, selectively delivered FA into the inflammatory pancreas lesion, and demonstrated protective effects against the detrimental aspects of the disease. The prepared nanoformulation by improving the pharmacological profile of FA and targeted delivery could be of therapeutic importance against the AP via suppressing the inflammation and oxidative stress.
