| Description | Succinyl phosphonate is a α-ketoglutarate dehydrogenase inhibitor . |
| In vitro | Succinyl phosphonate(0.01 mM) completely inhibits isolated brain KGDHC even in the presence of a 200-fold higher concentration of its substrate. In cultured human fibroblasts, 0.01 mM succinyl phosphonate produced 70% inhibition of α-ketoglutarate dehydrogenase complex. DESP and TESP are also inhibitory in the cell system, but only after preincubation, suggesting the release of their charged groups by cellular esterases[2]. Succinyl phosphonate inhibits 2-Oxoglutarate dehydrogenase , the first rate-limiting component of the mitochondrial multi-enzyme complex of oxidative decarboxylation of 2-oxoglutarate, in a highly selective and efficient manner[3]. |
