摘要:
The invention relates to complex compounds of germanium with amino acids and carboxylic acids of the general formula Ge[OH]a[AA]b[CA]c (I),where AA is an amino acid, CA is a carboxylic acid,a = 0-3, b = 1-3, c = 0-3, and 1<;b+c<;4,wherein AA and CA in the complex can be identical or different, and to a method for preparing the same. The method consists in preparing an aqueous suspension of germanium dioxide, adding an amino acid and a carboxylic acid to the aqueous suspension of germanium oxide produced, heating the mixture produced with agitation at a temperature of 40-100°C for 2-14 hours with subsequent filtering, removal of the water and production of a complex in solid form. The method makes it possible to prepare stable complex compounds with a controllable composition and a controllable ratio of germanium to amino acid and carboxylic acid which are stable in solid form and can be used in medicine.
