  Glycyrrhetinic acid derivatives as potent inhibitors of Na+, K+-ATPase. Synthesis and structure-activity relationships

  摘要：

  A series of ring A-modified GA derivatives (26 compounds) has been systematically synthesized and the structure-activity relationship investigated for inhibition of canine kidney Na+, K+-ATPase in vitro. The most potent inhibitory activity was found with a group of the 3-deoxygenated derivatives including 5, 6, 9, 10 and 11. The high inhibition may be closely related to the hydrophobic character of the A-ring of these compounds. This finding suggests that the ATP-binding site at the active center of the enzyme is located in a hydrophobic environment.

  The effect of glycyrrhetinic acid (GA) and GA-derivatives towards 11 beta-hydroxysteroid dehydrogenase (11 beta-HSD) was investigated. Novel compounds with modi. cations at positions C-3, C-11 and C-29 of the GA skeleton were prepared. Single crystal X-ray diffraction data of selected substances are reported and discussed.
