HOMO- AND HETERO-POLYAMINO-ACID DERIVATIVES OF FULLERENE С60, METHOD FOR PRODUCING SAME, AND PHARMACEUTICAL COMPOSITIONS BASED ON SAID DERIVATIVES.

摘要

The invention relates to the pharmaceutical industry and to medicine, specifically to novel homo- and hetero-polyamino-acid derivatives of fullerene С60 of general formula: C60(H)x{NH(CH2)nCOO -}x{NH3 +(L)COOH)}x, where n = 2-5, Ñ = 3, L = -(СÐ�2)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. A pharmaceutical composition comprises, as active substance, homo- and hetero-polyamino-acid derivatives of fullerene of formula C60(H)x{NH(CH2)nCOO -}x {NH3 +(L)COOH)}x, where n = 2-5, Ñ = 3, L = -(СÐ�2)m, where m = 1-5, or - CO(CH2)kCH(NH2)-, where k = 1-2.
