A search of new drugs for the treatment of viral infections and immune deficiencies of various etiologies is still one of the most important tasks of medicinal chemistry, pharmacy and medicine due to the wide spread of a number socially dangerous viral infections. This review is devoted to the chemical modification of Glycyrrhizic acid, the main component of licorice root, which is currently a leading natural glycoside promising as a basis for creation of new antiviral agents. The review presents the results of studies conducted over the past 15 years to obtain a library of Glycyrrhizic acid derivatives for biological studies and search of lead compounds. The synthesis of new biologically active derivatives and analogues (conjugates with amino acids and dipeptides, amino sugars, licorice triterpene acids conjugates with amino sugars, saponins and mono glycosides, heterocyclic amides) was carried out , and their antiviral and immune modulate properties were studied. Potent inhibitors of HIV, SARS CoV, Epstein-Barr, influenza A/H1N1 viruses and stimulators of primary immune response were found among GL derivatives and analogues produced.
