RAPID CATALYTIC METHOD FOR PREPARING RECOVERED FORM OF COENZYME Q10 TO BE USED IN PHARMACEUTICAL AND FOOD COMPOSITIONS Russian patent published in 2014 - IPC C07C43/23 C07C41/26 

FIELD: medicine, pharmaceutics.

SUBSTANCE: invention refers to the chemical-pharmaceutical and food industries. What is presented is a catalytic method for synthesis of a recovered form of coenzyme Q₁₀ (ubiquinol) which can be used for the rapid preparation of ubiquinol and various based pharmaceutical compositions and biologically active food additives possessing antioxidant and antihypoxant activity. The method for preparing ubiquinol of an oxidised form of coenzyme Q₁₀ is based on the catalytic recovery of Q₁₀ in the presence of a chemical reducing agent, a solvent and trace amounts of a Cu²⁺ copper catalyst for the pharmaceutical and food applications. In addition to the substantial reduction of the time for preparing ubiquinol, using the catalyst enables reducing the consumption of the chemical reducing agent and energy. Prepared ubiquinol can be used, e.g. for preparing various compositions, including ones in the liquid form and in the form of water-soluble powders containing inclusion complexes.

EFFECT: method for the synthesis of the recovered form of coenzyme Q₁₀ (ubiquinol).
