Zein-based nanoparticles (NPs) have attracted considerable attention as potential delivery systems for bioactive compounds. However, their application has been limited by poor stability and redispersibility. In this study, we addressed these challenges by fabricating zein nanocarriers using branching structural fructo-oligosaccharides (P-FOS) and sodium caseinate (NaCas) as costabilizers. P-FOS and NaCas were incorporated through an antisolvent coassembled precipitation technique. Astilbin (Ast) served as a model lipophilic bioactive compound to evaluate this innovative nanocarrier system. The results showed that Ast-loaded zein/P-FOS/NaCas nanoparticles (AZPS NPs) were successfully prepared, featuring a distinct spherical core-shell structure with a mean particle size of 156.4 ± 2.1 nm, zeta potential of -27.5 ± 3.5 eV and a uniform size distribution. Microstructural analysis using Fourier transform infrared spectroscopy, X-ray diffraction, and high-resolution transmission electron microscopy with energy-dispersive X-ray spectroscopy revealed that electrostatic interactions, hydrophobic interactions, and intermolecular hydrogen bonding contributed to the formation of the composite NPs. Compared to Ast-loaded zein NPs stabilized solely with NaCas (AZS), AZPS NPs exhibited superior stability under various environmental conditions (temperature, pH, and ionic strength) and demonstrated exceptional redispersibility after freeze drying. They also achieved an efficient Ast encapsulation rate of 92.3 % and a loading capacity of 12.4 %, compared to 73.56 % and 13.3 % in AZS, along with significantly enhanced bioavailability (2.4-fold) and antioxidation activity of Ast. Our findings suggest that P-FOS and NaCas are effective costabilizers for zein NPs, providing new insights into the application of fructans in zein-based composite NPs for the efficient delivery of hydrophobic bioactive compounds in cosmetics, pharmaceuticals, and food industries.
Scutellarein, a flavonoid compound from the traditional Chinese herb Scutellaria baicalensis, exhibits inhibitory effects against hepatocellular carcinoma (HCC), but its clinical application is limited by relatively weak potency. To enhance its antitumor activity, we synthesized a novel derivative, 5,6,7-trimethoxy-4'-benzimidazolyl scutellarein 6b (TBS6b), by introducing antitumor pharmacophores-trimethoxyphenyl and benzimidazole-into the scutellarein scaffold. TBS6b demonstrated significantly improved anti-HCC activity both in vitro and in vivo. Cell-based assays, including colony formation, EdU staining, wound healing, transwell migration, and western blot analysis, demonstrated that TBS6b significantly inhibits HCC cell proliferation, migration, and invasion. Mechanistically, we employed proteomic and transcriptomic sequencing, along with western blot and qRT-PCR experiments, to predict and validate atypical chemokine receptor 3 (ACKR3) as the target of TBS6b. Molecular docking studies confirmed that TBS6b binds tightly to the ACKR3 protein. Additionally, with the aid of pharmacological tools, we established that TBS6b promotes the ubiquitination and degradation of ACKR3. Tissue microarray analysis and queries of public databases revealed that ACKR3 expression is elevated in HCC tissues compared to adjacent non-cancerous tissues, correlating closely with patient survival. By constructing cell lines with either silenced or overexpressed ACKR3, we confirmed that ACKR3 promotes the proliferation, migration, and invasion of HCC. Finally, rescue experiments indicated that TBS6b exerts its anticancer effects primarily through targeting ACKR3. These findings establish ACKR3 as a critical target through which TBS6b mediates its anticancer activity against HCC.

Background: Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disease. The fruits of Illicium verum, which is a medicinal and edible resource, have been shown to have anti-inflammatory properties. Methods: In this study, we investigated the effects of I. verum extracts (IVEs) on human RA fibroblasts-like synoviocytes (RA-FLS) by using a sensitive and selective ultra-high-performance liquid chromatography with high-definition mass spectrometry (UPLC-HDMS) method. We subsequently analyzed the metabolites produced after the incubation of cultured RA-FLS with IVEs. Results: IVEs inhibited the proliferation and suppressed the migration of RA-FLS, and reduced the levels of inflammatory factors including TNF-α and IL-6. Twenty differential metabolites responsible for the effects of IVEs were screened and annotated based on the UPLC-HDMS data by using a cell metabolomics approach. Discussion: Our findings suggest that treating RA-FLS with IVEs can regulate lipid and amino acid metabolism, indicating that this extract has the potential to modify the metabolic pathways that cause inflammation in RA. Conclusions: This might lead to novel therapeutic strategies for managing patients with RA.
