选择性雌激素受体调节剂抗氧化作用的研究进展

Research advances of the antioxidative activities of selective estrogen receptor modulators

选择性雌激素受体调节剂(selective estrogen receptor modulators,SERMs)是一类能与雌激素受体结合的类似雌激素的非甾体化合物,依据靶组织和激素的内环境不同而具有雌激素受体刺激或拮抗作用。SERMs主要通过清除氧自由基和抑制脂质过氧化,调节NO和一氧化氮合酶水平,抑制线粒体膜通透性转换,改善线粒体内游离脂肪酸的代谢,调控非基因转录活性通路等机制发挥抗氧化作用。

Selective estrogen receptor modulators （SERMs） is a class of estrogen-like non-steroid compounds that are able to bind to steroid hormone receptors .They can act as estrogen receptor agonist or antagonist depending on the target tissue and hormonal environment .Additionally , SERMs play an antioxidant role by scavenging oxygen free redicals , inhibiting lipid peroxidation , adjusting the level of NO and NOS , inhibiting mitochondrial permeability transition , improving the metabolism of free fatty acids in the mitochon-drial and regulating non-genomic transcription pathway .
