2、抑制磷脂酶A2(phospholipaseA2)和脂氧合酶(lipoxygenase)的活性,从而抑制炎性介质(前列腺素、白三烯、血栓素A2等)的合成。3、抑制补体系统,抑制血清总补体活性,从而抑制变态疾病中补体参与的膜攻击复合物对组织的损伤。第六页,共29页。CH2-O-脂肪酸CH-O-花生四烯酸CH2-O-磷酸胆碱磷脂酶A2CH2-O-脂肪酸CH2OHCH2-O-磷酸胆碱花生四烯酸+白三烯前列腺素抑制膜磷脂抑制甘草酸铵抑制抑制抑制脂氧酶(LOX)环氧酶(cox)炎症第七页,共29页。3、皮质激素(类固醇)样作用康体多中的甘草酸铵分解的甘草次酸与类固醇结构相似具有肾上腺皮质激素样作用,激素样副作用少。甘草酸铵甘草次酸皮质酮类固醇第八页,共29页。组织中11β羟基类固醇脱氢酶(11-β-
HSD)有HSD1和HSD2两种亚型,它们催化GC的C11位的氧化和还原反应。HSD1具有还原酶的功能,通过结构修饰增强GC的活性。HSD2则为氧化酶,降低GC的活性。皮质激素代谢的关键酶第九页,共29页。Thekineticanalysisassociatedwiththelossof11alpha-2Hduringtheconversionofcortisol-13C4,2H1tocortisone-13C4by11beta-HSD2clearlyindicatedreduced11beta-HSD2
