11β-羟基类固醇脱氢酶1型（HSD11B1），也称为可的松还原酶，是一种NADPH依赖性酶，在包括肝脏、脂肪组织和中枢神经系统在内的关键代谢组织中高度表达。在这些组织中，HSD11B1将可的松还原为激活糖皮质激素受体的活性激素皮质醇。属于短链脱氢酶家族。

功能

这个基因编码的蛋白质是一种微粒体酶，催化应激激素皮质醇转化为非活性代谢物可的松。此外，编码的蛋白质可以催化相反的反应，即可的松转化为皮质醇。过多的皮质醇会导致中枢性肥胖，这种基因的一个特殊变异与儿童肥胖和胰岛素抵抗有关。在这个基因中发现了两个编码相同蛋白质的转录变体。[6]

Cortisol-cortisone equilibrium

临床意义

11β-HSD1被通常用于治疗消化性溃疡的药物卡宾诺酮抑制。此外，从甘草（glycyrrhiza glabra）根中提取的18α-甘草酸被发现是一种抑制剂。[7]

水杨酸盐下调肥胖小鼠脂肪组织中11β-HSD1的表达，从而解释了阿司匹林改善2型糖尿病血糖控制的原因。[8]绿茶中的表没食子儿茶素没食子酸酯也能有效地抑制这种酶；[9]绿茶是多种酚类物质的复杂混合物，其含量随着生产和加工的不同而变化，其中一些酚类物质是已知的改变遗传表达的HDAC抑制剂。绿茶中的EGCG通常很难被血液吸收。需要更多的研究才能得出明确的结论。
