Methods of treating mitochondrial fatty acid b-oxidation and/or transport disorders arising from mutant proteins in the mitochondrial fatty acid β-oxidation and transport metabolic pathways in patients are provided. The methods modulate the mitochondrial fatty acid β-oxidation pathway at the last step so that the product of the mutant protein accumulates and stabilizes the mutant protein and/or the substrate(s)/product(s) of the down stream reactions accumulate and possibly bind to allosteric sites on the mutant protein to stabilize it. Trimetazidine pharmacodynamics function as such in the β-oxidation pathway. Further, a synergistic effect is observed where trimetazidine and PPARδ agonist combination enhanced enzyme activity and presence significantly more than either alone.
提供了治疗患者线粒体
脂肪酸β-氧化和转运代谢途径中突变蛋白引起的线粒体
脂肪酸b-氧化和/或转运障碍的方法。这些方法在最后一步调节线粒体
脂肪酸β-氧化途径,使突变蛋白的产物积累并稳定突变蛋白,和/或使下游反应的底物/产物积累并可能与突变蛋白上的异位位点结合以稳定突变蛋白。
曲美他嗪的药效学在β-氧化途径中就是这样发挥作用的。此外,还观察到一种协同效应,即
曲美他嗪和
PPARδ 激动剂联合使用比单独使用更能增强酶的活性和存在。
