蘇州大學(xué)的實驗人員在上述論文中發(fā)現(xiàn)Nicotinamide ribose(煙酰胺核糖)可在大鼠心肌缺血再灌注(I/R)損傷模型中起到保護(hù)作用,并且利用AbMole提供的SIRT3抑制劑
3-TYP(3-(1H-1,2,3-triazol-4-yl) pyridine,AbMole,M8978),證實了Nicotinamide ribose的心臟保護(hù)作用主要依賴于SIRT3-SOD2軸抑制線粒體氧化應(yīng)激。在該實驗中,科研人員發(fā)現(xiàn)200 mg/kg的Nicotinamide ribose的預(yù)處理顯著減少大鼠的心肌梗塞面積,降低了血清中CK-MB和LDH水平,并改善大鼠心臟功能。同時,在體外模型中,0.5 mM 的Nicotinamide ribose也有效提高了H9c2細(xì)胞在OGD/R(缺氧和葡萄糖剝奪/再灌注)期間的存活率并減少了乳酸脫氫酶的釋放[5]。而3-TYP可阻斷Nicotinamide ribose的上述生物學(xué)效應(yīng),證實后者的活性與SIRT3有關(guān)。
2014年,AbMole的兩款抑制劑分別被西班牙國家心血管研究中心和美國哥倫比亞大學(xué)用于動物體內(nèi)實驗,相關(guān)科研成果發(fā)表于頂刊 Nature 和 Nature Medicine。
Inhibition of SIRT3 deacetylase activity reversed the cardioprotective effects of NR during myocardial I/R injury[5].
