BAM15(AbMole,M8653)是一種新型合成的線粒體解偶聯(lián)劑,可破壞電子傳遞鏈與ATP合成之間的質(zhì)子梯度。其作用原理如下:BAM15具有離子載體的特性,可在雙層脂膜中誘導(dǎo)質(zhì)子傳導(dǎo),導(dǎo)致跨線粒體內(nèi)膜的質(zhì)子梯度消失,增加活性氧積累,并抑制細(xì)胞增殖和遷移[1]。上述效應(yīng)已在人乳腺癌細(xì)胞系MDA-MB-231和小鼠乳腺癌細(xì)胞系EO771中得到驗(yàn)證[2]。此外,
BAM15(AbMole,M8653)通過(guò)抑制線粒體的功能還可調(diào)控巨噬細(xì)胞極化,在RAW264.7小鼠巨噬細(xì)胞中顯著抑制促炎性M1型極化,同時(shí)促進(jìn)抗炎性M2型標(biāo)志基因表達(dá)[3]。
在動(dòng)物實(shí)驗(yàn)中,C57BL/6J小鼠經(jīng)BAM15干預(yù)后表現(xiàn)出顯著的體重控制效果,同時(shí)伴隨糖代謝改善和肝臟脂肪沉積減少[4]。BAM15的納米顆粒形式(以PLGA作為載體)在
LPS(Lipopolysaccharides,脂多糖) 誘導(dǎo)的膿毒癥小鼠模型中顯示:該納米粒子可被脾臟和肝臟巨噬細(xì)胞特異性攝取,減輕全身炎癥反應(yīng)并保護(hù)肝損傷[3]。BAM15還被用于增強(qiáng)CD7CAR-T細(xì)胞的抗腫瘤功能:在異種移植小鼠模型中,低濃度的BAM15即可提升細(xì)胞毒性并降低細(xì)胞因子釋放[5]。
