Succinyl phosphonate is a α-Ketoglutarate Dehydrogenase Complex (KGDHC) modulator with neuroprotective activity. Succinyl phosphonate protects this complex, reduces cellular succinyl-CoA concentration, downregulates protein succinylation levels, and inhibits the activity of the α-ketoglutarate dehydrogenase complex. Succinyl phosphonate corrects hypoxic or ethanol-induced behavioral impairments, modulates exploratory behavior and emotional stress responses, and improves hypoxia tolerance. Succinyl phosphonate reduces glutamate excitotoxicity, restores the activity of the α-ketoglutarate dehydrogenase complex, reverses the changes in glutamate dehydrogenase and glutamine synthetase activities induced by β-amyloid (Amyloid-β), modulates cognitive function, and prevents β-amyloid-induced neuronal damage. Succinyl phosphonate improves microglial senescence, alleviates neuroinflammation, reactive oxygen species (ROS) production, lipid peroxidation, and the expression of proinflammatory cytokines. Succinyl phosphonate can be used in the research of Alzheimer's disease, aging-related neuroinflammation, and Parkinson's disease.

At equivalent molar concentrations, both the salt and free forms of a compound exhibit comparable biological activity. Nevertheless, the salt form (Succinyl phosphonate trisodium salt) usually boasts enhanced water solubility and stability.

    Depiction of representative voltage responses to application of 3 µM and 10 µM glutamate of control neurons, Succinyl phosphonate trisodium salt (SP)-treated neurons and TH-treated neurons. Responses were characterized by triggering of or increase in action potential discharge, and at 10 µM glutamate, by a transition into depolarisation block, which manifests itself in a cessation of discharge activity during sustained depolarization. Action potentials are truncated at −10 mV.

    体外実験

    Succinyl phosphonate (10 μM; 72 h) reduces succinylation levels and succinyl-CoA concentrations, mitigates LPS (HY-D1056)-induced reactive oxygen species production, lipid accumulation, lipid peroxidation, and pro-inflammatory cytokine expression in BV2 cells and primary mouse microglia, and reduces senescence in VP-16 (HY-13629)-induced aged BV2 cells[3].
    Succinyl phosphonate upregulates active OGDHC quantity in cultured neurons, but this upregulation is impaired by co-treatment with ethanol[4].

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
