To overcome the poor solubility, permeability, and bioavailability of the plant isoflavone daidzein (DAI), a novel salt of DAI with anhydrous piperazine (PIP) was obtained based on cocrystallization strategy. The new salt DAI-PIP was characterized by powder X-ray diffraction (PXRD), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), Fourier-transform infrared (FT-IR) spectroscopy, and optical microscopy. The results showed that the maximum apparent solubility (S) of DAI-PIP increased by 7.27-fold and 1000-fold compared to DAI in pH 6.8 buffer and water, respectively. The peak apparent permeability coefficient (P ) of DAI-PIP in the Caco-2 cell model was 30.57 ± 1.08 × 10 cm/s, which was 34.08% higher than that of DAI. Additionally, compared to DAI, the maximum plasma concentration (C) value of DAI-PIP in beagle dogs was approximately 4.3 times higher, and the area under the concentration-time curve (AUC) was approximately 2.4 times higher. This study provides a new strategy to enhance the dissolution performance and bioavailability of flavonoid drugs, laying a foundation for expanding their clinical applications.

Ferulic acid (FA) is a phenolic compound obtained naturally and is a versatile antioxidant identified for its potential in managing hypertension. However, its application is constrained due to its classification as a BCS Class IV moiety. To address this, we concentrated on improving its solubility and permeability by developing nanostructured lipid carriers (NLCs) of FA using emulsification probe sonication technique.

Background: Intestinal barrier dysfunction may lead to a break in tolerance and development of food allergy (FA). There is contradictory evidence on whether intestinal permeability (IP) is altered in IgE-mediated FA. Thus, we sought to determine whether IP differed between children with eczema who did (FA group) or did not (atopic controls, ACs) develop FA and whether peanut sensitization, allergy, and early introduction impacted IP using serum biomarkers zonulin, soluble CD14, and Intestinal Fatty Acid Binding Protein among randomly selected participants enrolled in the Learning Early About Peanut allergy trial.

This study evaluated the potential of starch (ST) and carrageenan (CRG) in packaging film formulation. CRG isolated from the seaweed (SW) was blended with starch and cast to obtain films whose moisture content (MC), total soluble matter (TSM), degree of solubility (DS), water vapor permeability (WVP), opacity (O), contact angles (CA), moisture absorption (MA), and percent elongation (PE) were evaluated.
