Redox Biol:多种树!坚叶樟树是这样保护我们肺的

2017-09-26 Emma MedSci原创

直接暴露于环境的氧化剂和毒物的人体肺组织容易受到伤害,导致急性或慢性氧化损伤。Nrf2(核因子红细胞2相关因子2)代表中枢细胞防御机制,并且是用于开发抗氧化损伤诱导的人类肺部疾病的药物靶标。

直接暴露于环境的氧化剂和毒物的人体肺组织容易受到伤害,导致急性或慢性氧化损伤。Nrf2(核因子红细胞2相关因子2)参与中枢细胞防御机制,并且是用于开发抗氧化损伤诱导的人类肺部疾病的药物靶标。研究人员之前研究发现,坚叶樟树的提取物EtOH能够通过激活Nrf2保护人支气管上皮细胞免受氧化损伤。研究人员又对坚叶樟树地上的部分植物进行了系统的化学成分研,通过使用NAD(P)H:醌还原酶(QR)测定法,分离了三十种化学成分,并进一步评估其Nrf2诱导潜力。

在这些纯化组分中,含有NLD、THD、α,β-不饱和酮基三倍体和苯二酚共聚酚,3,3'等,能显著激活Nrf2及其下游基因,NQO-1和γ-GCS能够增强人肺上皮细胞中Nrf2的核易位和稳定性。更重要的是,NLD和THD在Nrf2的诱导剂量下没有毒性。THD还表现出中断Nrf2-Keap1 PPI(蛋白质-蛋白质相互作用)的潜力,并且NLD和THD能够保护人肺上皮细胞免受亚砷酸钠[As(III)]诱导的细胞毒性。

该研究表明,NLD和THD作为Nrf2的两种新型激活剂,具有预防人肺组织急性和慢性氧化损伤的应用潜力,可进行下一步的研究。
