BAY-876(AbMole,M8659)是一種高選擇性葡萄糖轉(zhuǎn)運(yùn)蛋白1(GLUT1)抑制劑,通過靶向抑制GLUT1介導(dǎo)的葡萄糖攝取,在多種研究中展現(xiàn)出顯著的代謝調(diào)控與抗增殖作用。其作用機(jī)制主要包括:(1)直接抑制GLUT1蛋白表達(dá),如Western blot分析顯示其在人結(jié)直腸癌細(xì)胞系(HCT116、DLD1、COLO205、LoVo)中可降低GLUT1蛋白水平[1]。(2)通過阻斷糖酵解通路,誘導(dǎo)線粒體呼吸增強(qiáng)和活性氧(ROS)積累,導(dǎo)致細(xì)胞凋亡率上升,在體外實(shí)驗(yàn)中2 nM BAY-876即可抑制高糖誘導(dǎo)的GLUT1 mRNA和蛋白表達(dá)[2]。(3)與EGFR信號(hào)通路相互作用:BAY-876能通過抑制EGFR下游通路增強(qiáng)其它抑制劑(如
Osimertinib)的敏感性[3]。
BAY-876(AbMole,M8659)在多種細(xì)胞系中表現(xiàn)出劑量依賴性的抑制效果。例如,在卵巢癌細(xì)胞中,BAY-876(CAS No.:1799753-84-6)通過阻斷糖酵解和錨定非依賴性生長,顯著抑制細(xì)胞增殖[4]。0.05 μM的BAY-876能特異性抑制GLUT1介導(dǎo)的肌肉細(xì)胞葡萄糖攝取[5]。BAY-876還能顯著抑制砷酸鹽處理的L-02肝細(xì)胞中GLUT1膜定位及葡萄糖攝取[6]。在小鼠異種移植模型中,BAY-876表現(xiàn)出顯著的抗腫瘤活性。例如,在結(jié)直腸癌移植瘤中,BAY-876治療組顯示GLUT1表達(dá)抑制和腫瘤生長減緩[1]。BAY-876還被用于研究代謝重編程與免疫調(diào)控之間的關(guān)聯(lián)。例如,在CD4 +T細(xì)胞中,GLUT1抑制可減少20%的IFN-γ分泌,同時(shí)巨噬細(xì)胞中TNF分泌降低27%[7]。
