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. A pharmaceutical composition which exhibits activity against the herpes virus, flu viruses of various origin and HIV, and also anti-tumor and anti-psoriatic activity, comprising, as active substance, an effective quantity of hydrated N-fullerene amino acids.
