A pyridyl triazole (pyta) modified sucrose ligand was prepared in a seven step synthesis using d-glucose as the protection group for d-fructose and starting from commercially available sucrose. After complexation with Ru(bpy)Cl precursor, the sucrose-conjugated Ru complex of the general formula [Ru(bpy)(L)]Cl was formed. Acidic cleavage of the d-glucose unit led to the first d-fructose conjugated metal complex viad-fructose C6 in literature. Additionally, pyta-modified d-fructose via C1 and the corresponding Ru complex were synthesized. All compounds were analyzed by R values, specific rotation, NMR, IR, UV/Vis and fluorescence spectroscopy, mass spectrometry and elemental analysis.

A novel delivery system comprising N-succinic anhydride (N-SAA) and D-fructose co-conjugated chitosan (NSCF)-modified polymeric liposomes (NSCF-PLip) were designed to enhance oral delivery of paclitaxel (PTX) by targeting monocarboxylate transporters (MCT) and glucose transporters (GLUT). The synthesized NSCF was characterised by FT-IR and H NMR spectra. The prepared 30.

This research examines the interaction between human serum albumin (HSA) and various sugar forms (β-D-fructofuranose (FRC), α-D-glucopyranose (GLC), Keto-D-fructose (FRO), Aldehydo-D-glucose (GLO), and modified Aldehydo-D-glucose (GLOm)) using fluorescent spectroscopy, molecular docking simulations, molecular dynamics, protein conformational clusters (EnGens), molecular fractionation with conjugate caps (MFCC) and quantum biochemistry analysis. We analyze molecular and quantum aspects, uncovering interaction energies between sugar atoms and amino acids. Total interaction energy considers protein fragmentation, energetic decomposition, and interaction energy from a bottom-up perspective.

Ovalbumin (OVA) was modified by fructose (Fru) and galactose (Gal) to study the structure, IgG/IgE binding capacity and effects on human intestinal microbiota of the conjugated products. Compared with OVA-Fru, OVA-Gal has a lower IgG/IgE binding capacity. The reduction of OVA is not only associated with the glycation of R84, K92, K206, K263, K322 and R381 in the linear epitopes, but also with conformational epitope changes, manifested as secondary and tertiary structural changes caused by Gal glycation.

Article Synopsis
- Traditional blueberry planting methods are becoming inadequate due to increasing commercial demands, leading to a rise in soilless substrate cultivation as a solution in the blueberry industry.
- Different soilless substrate treatments, like 50:50 peat/pine bark (FPB) and 50:50 pine bark/rice husk (FBR), significantly affect the appearance and quality of blueberries, with FPB yielding larger, more vibrant fruits and higher antioxidant levels, while FBR produced fruits with increased total phenols and flavonoids.
- Metabolomic analysis reveals notable variations in compounds such as flavonoids and carbohydrates between treatments, highlighting how specific substrates can enhance blueberry quality and offering insights for optimizing soilless cultivation practices.
