產(chǎn)品簡(jiǎn)介:
SB-415286是糖原合酶激酶-3 (GSK-3)的有效和選擇性細(xì)胞滲透性抑制劑,Ki為31 nM。它對(duì)GSK-3和GSK3β表現(xiàn)出相似的效力[1]。
SB-415286抑制GSK-3活性,促進(jìn)人肝細(xì)胞中糖原合成,并誘導(dǎo)HEK293細(xì)胞中由連環(huán)蛋白-LEF/TCF調(diào)節(jié)的報(bào)告基因表達(dá)[1]。在初級(jí)神經(jīng)元中,它可以防止被抑制的PI3k通路活性誘導(dǎo)的細(xì)胞死亡[2]。進(jìn)一步的研究表明,SB-415286誘導(dǎo)的GSK3β活性降低可以抑制細(xì)胞周期蛋白D1的下調(diào)、細(xì)胞周期停滯和化療敏感性,這些都是由雷帕霉素介導(dǎo)的[3]。對(duì)GSK-3β的藥理學(xué)抑制顯著損害了p21和Puma的p53依賴性反式激活,但促進(jìn)了Bax的p53依賴性構(gòu)象激活,導(dǎo)致p53介導(dǎo)的損傷反應(yīng)從細(xì)胞周期停滯轉(zhuǎn)變?yōu)榈蛲鯷4]。
SB-415286通過與線粒體相關(guān)的機(jī)制減輕缺血-再灌注損傷。SB-415286減少了腺嘌呤核苷酸轉(zhuǎn)運(yùn)和VDAC的磷酸化,然后增加了Bcl-2與線粒體的結(jié)合,并阻斷了心肌細(xì)胞中線粒體通透性轉(zhuǎn)換孔的開放[5]。SB-415286對(duì)輻射誘導(dǎo)的海馬神經(jīng)元凋亡也有保護(hù)作用。SB-415286誘導(dǎo)的GSK-3β抑制可導(dǎo)致MDM2上調(diào),從而調(diào)節(jié)p53降解和p53依賴性細(xì)胞反應(yīng)[6]。
最近在小鼠模型中的研究進(jìn)一步證實(shí),SB-415286是一種對(duì)抗輻射誘導(dǎo)的中樞神經(jīng)系統(tǒng)壞死的神經(jīng)保護(hù)劑。與DMSO處理的小鼠相比,在照射前用SB415286處理的小鼠(即靶向左半球的單個(gè)45-Gy部分)顯示出對(duì)輻射誘導(dǎo)的壞死的顯著保護(hù),這通過體內(nèi)MRI確定[7]。
