技术领域

技术背景
五环三萜类天然产物齐墩果酸(Oleanolic acid,简称OA)具有多种潜在的药用价值,如器官保护、治疗慢性肾病、抗肿瘤、降血脂、降血糖、抗炎,抗溃疡等,其较弱的生物活性和不理想的物理性质限制了他的临床应用,因此以齐墩果酸为构架的化学修饰也成为药物研究的方向之一。特别是近年来的研究证明这类衍生物的抗炎药理活性是通过干预多个生化信号传导通路实现的,如抑制多个诱发炎症的媒介,包括IFN-γ诱导的一氧化氮的合成酶(INOs)和COX-2的合成等,特别是激活KEAP/NRF2/ARE信号通路,诱导多种抗炎和抗氧化蛋白的生成,例如HO-1和NQO-1的上调。具有高活性、低毒性以及高生物利用度的齐墩果酸衍生物一直是当前待解决的问题。
