PREPARATION OF NEW GLYCYRRETIC ACID DERIVATIVES WITH NITROGEN-CONTAINING LIGANDS

This article presents the results of a study of obtaining new derivatives of glycyrrhizic acid aglycone with nitrogen-containing ligands. Natural compounds isolated from plant materials are relatively low toxic, can exhibit unique physical and chemical properties, and have a wide range of biological activity. One of these natural compounds is 3β-hydroxy-11-oxo-12-en-18βН, 20β-olean-30 acid, 3-О-(2҆-О-β-D-glucuronopyranosyl)-β-D-glucuronopyranoside (glycyrrhizic acid, GK) is the main active principle of licorice root (Glycyrrhiza glabra L.), which grows on the territory of the Republic of Uzbekistan and is a renewable natural source. With the ability to self-organize and recognize other particles and molecules, natural biologically active compounds are the subject of current chemical research aimed at modeling various biochemical processes. One of such widespread natural compounds are plant triterpenoids, glycyrrhizic (GA), glycyrrhetic (GlK), oleanolic, betulinic and ursalic acids, etc. The article also presents the results of a study of the dependence of the complex formation of GlK with nitrogen-containing ligands depending on the structural changes in the guest molecule. New supramolecular derivatives of GlK with some nitrogen-containing ligands were obtained by the liquid phase method, their physicochemical and spectral (UV, IR) characteristics of the synthesized compounds were determined, and the chemical structure was analyzed on the basis of mass spectrometry data.
