FIELD: biochemistry.
SUBSTANCE: describes is new chemical compound, namely glycirrisine acid derivative with L-prolin: 3-O-{2-O-[N-(β-O-glucopyranosyluronoyl)-L-prolin-N-(β-D-glucopyranosyluronoyl)-L-prolin]}-(3β,20β)-11-oxoolean-12-en-30-oic acid, stimulating of humoral immune response. Said compound has low toxicity and increases agglutinins levels (by 3,7 times) and hemolysines level (by 3 times) in mouth blood in contrast with control while administrating of 2 mg/kg.
EFFECT: preparation with increased stimulating activity in relation to agglutinin production.
