Butein是一种具有抗氧化作用的查尔酮,具有多种药理作用。
活性氧(ROS)在细胞内通过多种机制产生,依赖于细胞和组织类型,主要通过细胞膜、线粒体、过氧化物酶体和内质网的ROS NADPH氧化酶(NOX)复合体而产生,可由牙科粘合漂白剂和牙髓病诱导产生,ROS可激活氧化应激。[1]ROS是正常氧代谢的天然产物,在细胞信号和内稳态中具有重要作用。但是,在多次环境压力后,ROS水平急剧增加。[2] 在butein 存在时,H2O2诱发的细胞毒性和ROS生成会被阻断,这一效果是剂量依赖的。由于ROS的双重作用,基于促氧化和抗氧化功能的抗癌制剂都被研发出来。
Butein可诱导B16黑色素瘤细胞和人早幼粒白血病细胞凋亡,抑制糖尿病并发症,并能抑制诸如蛋白激酶和谷胱甘肽还原酶等酶类。[3,4,5,6]最近,Butein从R. verniciflua中分离出来,通过JNK–Nrf2/ARE依赖的HO-1表达,抑制HDP细胞中H2O2引起的氧化性细胞损伤。[7]另外,体外流式细胞仪分析和RT-PCR表明,Butein可通过抑制NF-kB活性,减弱VEGF和MMP-9的活性。并且,通过电泳迁移率变动分析(EMSA)和酶联免疫吸附试验(ELISA)发现,Butein可抑制肿瘤坏死因子ɑ和佛波醇-12-肉豆蔻酸酯-13-乙酸酯诱导的VEGF和MMP-9表达,最终导致前列腺癌细胞生长、侵袭和血管生成的抑制。[8]因此,Butein有希望成为治疗多种牙科疾病的制剂。
