  Synthesis of novel 3-amino and 29-hydroxamic acid derivatives of glycyrrhetinic acid as selective 11β-hydroxysteroid dehydrogenase 2 inhibitors

  摘要：

  Glycyrrhetinic acid, the metabolite of the natural product glycyrrhizin, is a well known nonselective inhibitor of 11 beta-hydroxysteroid dehydrogenase (11 beta-HSD) type 1 and type 2. Whereas inhibition of 11 beta-HSD1 is currently under consideration for treatment of metabolic diseases, such as obesity and diabetes, 11 beta-HSD2 inhibitors may find therapeutic applications in chronic inflammatory diseases and certain forms of cancer. So far, no selective 11 beta-HSD2 inhibitor has been developed and neither animal studies nor clinical trials have been reported based on 11 beta-HSD2 inhibition. Starting from the lead compound glycyrrhetinic acid, novel triterpene type derivatives were synthesized and analyzed for their biological activity against overexpressed human 11 beta-HSD1 and 11 beta-HSD2 in cell lysates. Several hydroxamic acid derivatives showed high selectivity for 11 beta-HSD2. The most potent and selective compound is active against human 11 beta-HSD2 in the low nanomolar range with a 350-fold selectivity over human 11 beta-HSD1. (C) 2010 Elsevier Ltd.

  Disclosed are methods and compositions for treating alcohol dependence by administration to a patient of an inhibitor of 11β-hydroxysteroid dehydrogenases (11β-HSD) to modulate glucocorticoid effects. One such compound is the 11β-HSD inhibitor carbenoxolone (18β-glycyrrhetinic acid 3β-O-hemisuccinate), which has been extensively employed in the clinic for the treatment of gastritis and peptic ulcer. Carbenoxolone is active on both 11β-HSD1 and 2 isoforms. Here, carbenoxolone is surprisingly shown to reduce both baseline and excessive drinking in rats and mice. The carbenoxolone diastereomer 18α-glycyrrhetinic acid 3β-O-hemisuccinate (αCBX), which the applicants discovered to be selective for 11β-HSD2, was also effective in reducing alcohol drinking in mice. Thus, 11β-HSD inhibitors are a new class of candidate alcohol abuse medications and existing 11β-HSD inhibitor drugs may be re-purposed for alcohol abuse treatment.
