  • Publication number: 20130165691
    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.

  • Publication number: 20130165692
    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.
