Novel 18β-glycyrrhetinic acid analogues as potent and selective inhibitors of 11β-hydroxysteroid dehydrogenases
摘要:
Extensive structural modifications to the 18beta-glycyrrhetinic acid template are described and their effects on the SAR of the 11beta-hydroxysteroid dehydrogenase isozymes type 1 and 2 from the rat are investigated. Isoform selective inhibitors have been discovered and compound 7 N-(2-hydroxyethyl)-3beta-hydroxy-11-oxo-18beta-olean-12-en-30-oic acid amide is highlighted as a very potent selective inhibitor of 11beta-hydroxysteroid dehydrogenase 2 with an IC50 = 4 pM.

main active compound in liquorice root. Its aglycone, glycyrrhetinic acid, has shown several beneficial pharmacologicalactivities. This study reports the synthesis and screening of a series of glycyrrhetinic acid analogs as AChE-Is. Fourteen derivatives were prepared, of which five derivatives are recorded as new viz., 3-phenyl-carbamoyl-18β-glycyrrhetinic acid (J9), 3-acetyl-18β-glycyrrhetinic-30-anilinamide

Glycyrrheticacid (2, 3β-hydroxyl-11-oxo-olean-12-ene-29-oic acid), a pentacyclic triterpenoid isolated from Glycyrrhiza glabra, is known to possess a wide range of biological activities. Herein, we report the synthesis and antiproliferative activity of 3-O-ether derivatives of glycyrrheticacid. The cytotoxicity of the prepared derivatives was investigated in three cancer cell lines, including human
