Фридман, С.М. 2004 2018-01-19 New amino acid derivatives of glycyrrhizic acid and its methyl ester were selectively synthesized using active /V-succinimide esters. The compounds with residues of glycine ethyl ester and alanine methyl and butyl esters increased the level of agglutinins and hemolysins in blood serum of mice two- to threefold in comparison with the control upon parenteral administration at a dose of 2 mg/kg for 14 days. https://repo.bashgmu.ru/publication/633 https://repo.bashgmu.ru/files/698
