fibroblasts cell cultures. Of these, two selected compounds demonstrated to distribute at NMR detectable levels within the cytosolic and mitochondrial sites following their perfusion to isolated rat livers, with no detrimental effects on cell energetics and aerobic respiration. This study provided a new molecular scaffold for further development of in situ spectroscopic real-time monitoring of mitochondrion/cytosol
设计并合成了一系列将二乙氧基磷酰基与烷基连接的三苯基溴化tail尾部结合的线粒体靶向α-氨基膦酸酯,并对其pH敏感的31 P NMR特性和体内外生物学活性进行了评估。结果表明,许多这些线粒体氨基膦酸酯的p K a值符合线粒体pH范围,短暂弛豫和与敏感的31相容的化学位移参数P NMR检测以及对绿藻和鼠成纤维细胞培养物的低细胞毒性。在这些化合物中,有两种选择的化合物在向分离的大鼠肝脏灌注后,在胞质和线粒体位点以NMR可检测的水平分布,对细胞能量和有氧呼吸没有有害影响。该研究为线粒体/细胞质pH梯度原位光谱实时监测的进一步发展提供了新的分子支架。
