Francesco Maione等人对单铵甘草酸盐抗炎抗伤害以小鼠实验进行以及生化和对接研究。在小鼠单次给药后的,一次腹腔注射AG对酵母多糖引起的足跖水肿和足跖肿胀均有抗炎作用腹膜炎。此外,在几种疼痛动物模型中,如扭体试验、福尔马林试验,酵母多糖诱发的痛觉过敏,试验前24小时给予AG可诱发痛觉过敏强烈的抗伤害作用。综上所述,所有这些发现都突出了AG在疼痛和或炎症相关疾病临床治疗中的潜在应用。AG与mPGES-2和COX-2的关键氨基酸相互作用。经过实验结果分析,甘草酸单铵的抗炎抗伤效应来自其与mPGES-2和COX-2的特异受体相互作用 。AG在结合处的定位较好COX-2与Trp387、Ser530(氢键)和Arg120等关键氨基酸相互作用时的囊袋。此外,通过结合刚性和柔性分子对接研究,两种可能的方法提出了AG与5-LO相互作用的机制:非氧化还原竞争结合和非氧化还原竞争结合Fe2+络合。而理论计算结果显示,前者结合能相对更低。[11]
