In this study, we adopted the synergistic modification technology of hydrodynamic cavitation and snail enzyme, to improve yield activity soluble dietary fibers (SDFs) rice husk. The physicochemical properties, structural changes, inhibition α-glucosidase α-amylase SDFs were examined in vitro. This treatment significantly increased 18.64 % ± 0.16 %, reduced particle size 122.33 0.26 nm, specific surface area 1.718 0.002 m2/g. absolute value zeta potential -36.39 0.12 mV, indicating an excellent solution stability gel-forming ability. At same time, water-holding, oil-holding, swelling capacities enhanced, reaching 8.52 0.09 g/g, 4.85 0.29 7.29 0.25 mL/g, respectively. Structural analysis showed that destroyed fiber structure, produced a large number small molecule fragments, changed monosaccharide components functional group distribution. Functional evaluation inhibitory effect CE-SDF on was enzymatic reaction kinetic revealed both enzymes competitive inhibitors, with IC50 values 2.893 1.727 mg/mL, summary, enzyme greatly optimized properties husk SDFs, providing theoretical basis for its application field hypoglycemic drugs foods.

Abstract Phenolic compounds are a new class of Carbonic Anhydrase inhibitors (CAIs). Despite numerous advancements in treatment approaches, cancer continues to be growing health problem worldwide. In our study, we tested the effects 4-hydroxy-3-methoxyacetophenone (1) , doxycycline hydrochloride (2) 5,7-dichloro-8-hydroxyquinoline (3) methyl 3,4,5-trihydroxybenzoate (4) 2-hydroxy-4-methylacetophenone (5) 6-hydroxy-4-methylcoumarin (6) and 2,5-dihydroxyacetophenone (7) on Achetylcholynesterase (AChE), Butrycholynesterase (BChE), Human anhydrase I (hCA I) enzymes. The U2OS human osteosarcoma cell line was used determine anticancer potential these phenolic compounds. proliferation colony formation were analyzed using Neutral Red Uptake (NRU) assay clonogenic assay. K i values arachidonoyl dopamine, 2,4,6-trihydroxybenzaldehyde, 3,4-dihydroxy-5-methoxybenzoic acid 203.80, 1170.00, 910.00 mM, respectively, for hCA I, 75.25, 354.00, 1510.00 II II). Additionally, IC 50 from vivo studies found range 173.25 1360.00 mM CA II, CO 2 -hydratase activity methods. NRU results revealed that had dose-dependent cytotoxic effect cells. cells determined > 100, 93.7, 81.4, 26.9, 53.1, 100 µM, respectively. Notably, compound with lowest value, significantly suppressed at 5 10 µM concentrations. These demonstrated could inhibit approximately 30% CO2-hydratase total enzyme rat erythrocytes. Furthermore, suggests molecules pave way development approaches treatment. activities seven studied compared against AChE (PDB ID: 4M0E), BChE 5NN0), 2CAB), E3 ubiquitin-protein ligase 4HG7) proteins. binding free energy molecule highest docking score is computed MM/GBSA techniques. Finally, molecular dynamics simulations performed between 4M0E protein over 0–200 ns interval. Graphical abstract
