  • Patent number: 9221746
    Abstract: The invention relates to the pharmaceutical industry and to medicine, specifically to novel homo- and hetero-polyamino-acid derivatives of fullerene C60 of general formula: C60(H)x{NH(CH2)nCOO—}x{NH3+(L)COOH)}x, where n=2-5, x=3, L=-(CH2)m, where m=1-5, or —CO(CH2)kCH(NH2)—, where k=1-2, characterized in that the compounds comprise covalently bonded amino-acid groups and polar ionic forms of the amino acids, and also to a method for producing said derivatives, and to the production of pharmaceutical compositions based on same. The method for producing homo- and hetero-polyamino-acid derivatives of fullerene is based on the reaction of a nucleophilic bond of amino acids to fullerene, forming covalently bonded amino-acid derivatives of fullerene, with the subsequent introduction of polar ionic forms of the amino acids.

  • Patent number: 9096492
    Abstract: The invention relates to the pharmaceutical industry and to medicine, specifically to novel hydrated amino-acid derivatives of fullerene C60 of general formula C60(H)3{NH(CH2)nCOOH}3.xH2O, where C60-fullerene, n=5, 6, 7, x=8-10, and also to a method for producing said derivatives, and to the production of pharmaceutical compositions on the basis thereof. Hydrated N-fullerene amino acids are formed in the interaction of fullerene with 15 times the molar excess of anhydrous potassium salts of amino acids in a medium of organic aromatic solvent with slow addition to the resultant suspension of an interphase catalyst and with mixing and heating to a temperature not exceeding 60° C. until the solution is completely decolorized and a solid residue formed, after which the latter is separated out, and then 0.8 M of aqueous solutions of potassium salts of fullerene amino-acid derivatives is treated with a solution of organic or mineral acids, followed by centrifugation, rinsing and drying of the residue.

  • Publication number: 20110208258
    Abstract: The invention relates to medicinal equipment and is useful in physiotherapy for controlling the functions of biological objects. A method for capturing the changes induced by the action of acoustic and electromagnetic fields of a biological medium using a crystal whose structure comprises at least one semiconductor junction is offered. The crystal is positioned on an insulating plate which is in direct contact with the biological medium, and the changes in the crystal structure are captured by means of exposing the semiconductor junction thereof to a cut-off polarity electric pulse.
