Complexes of Glucarolactones with Water-Soluble Copolymers of N-Vinylpyrrolidone with N-Vinylamine as Inhibitors of β-Glucuronidase Efficacy

Water-soluble complexes of N-vinylpyrrolidone/N-vinylamine copolymers with lactones of D-glucuronic acid were obtained and characterized by chromatographic, spectral, and hydrodynamic methods. The complexes efficiently inhibited the enzyme β-glucuronidase that causes the appearance of bladder tumors. The products demonstrated prolonged action and were stable during storage.

Silver nanoparticles doped with silver cations, stabilized with maleic acid copolymers: specific structure, antimicrobial properties

The combined composites containing silver nanoparticles and silver cations were proposed. Water-soluble complexes of silver nanoparticles (AgNPs) stabilized by copolymers of maleic acid with ethylene or N-vinylpyrrolidone were doped with...

Thermal Exposure Methods Intensification by the Use of Catalysts

The article reviewed the catalysts used for upgrading high-viscosity oil in the reservoir. It is concluded that the most widespread and effective catalysts are oil-soluble complexes based on transition metals.
