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.
本发明公开了通过向患者施用 11β-羟基类固醇脱氢酶(11β-HSD)抑制剂以调节糖皮质激素作用来治疗酒精依赖症的方法和组合物。其中一种化合物是 11β-HSD 抑制剂卡本诺酮(18β-甘草次酸 3β-O-hemisuccinate ),临床上已广泛用于治疗胃炎和消化性溃疡。卡贝诺酮对 11β-HSD1 和 2 同工酶均有活性。令人惊讶的是,羧甲诺龙在大鼠和小鼠体内可减少基线饮酒量和过量饮酒量。申请人发现,羧诺龙的非对映异构体 18α-甘草次酸 3β-O-hemisuccinate (αCBX)对 11β-HSD2 具有选择性,也能有效减少小鼠的饮酒量。因此,11β-HSD 抑制剂是一类新的候选酗酒药物,现有的 11β-HSD 抑制剂药物可重新用于酗酒治疗。
