Efficient synthesis of piperazinyl amides of 18β-glycyrrhetinic acid
Beilstein J. Org. Chem. 2020, 16, 798–808, doi:10.3762/bjoc.16.73
- conditions. Furthermore, the reasons for the appearance of byproducts were elucidated. Crystallographic data of a selected piperazinyl amide is reported. Keywords: 18β-glycyrrhetinic acid; piperazinyl amides; synthesis; Introduction Glycyrrhizin was the major bioactive component in Glycyrrhiza uralensis
- fisch root. 18β-glycyrrhetinic acid (1, Figure 1) was then obtained by hydrolysis of glycyrrhizin. 18β-glycyrrhetinic acid and its derivatives have been extensively investigated in medicinal chemistry for their various biological activities, including anti-inflammatory [1], antiulcer [2], antioxidative
Synthesis and antiviral activities of spacer-linked 1-thioglucuronide analogues of glycyrrhizin
Beilstein J. Org. Chem. 2012, 8, 705–711, doi:10.3762/bjoc.8.79
- need for new antiviral compounds. Starting from the natural, antivirally active compound glycyrrhizin, spacer-bridged derivatives were generated with improved antiviral activity against the influenza A virus infection. Simplified analogues of the triterpene saponin glycyrrhizin containing 1-thio-β-D
- . The deprotected compounds containing these carboxylic acid appendices mimic the glycon part of glycyrrhizin as well as the hemisuccinate derivative of glycyrrhetinic acid, carbenoxolone. Antiviral activities of the compounds were determined in a biological test based on influenza A virus-infected
- cells, wherein the 3-(2-thioethyl)-N-acetylamino- and 3-(2-thioethyl)-thio-linked glucuronide derivatives were effective inhibitors with IC50 values as low as 54 µM. Keywords: antiviral activity; carbenoxolone; glycyrrhizin; influenza A virus; thioglycoside; triterpene; Introduction The triterpene
