Succinyl phosphonate
Based on 14 publication(s) in Google Scholar
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.

Biological Activity
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].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Succinyl phosphonate (10 nM; intra-CA1; 30 minutes after first Aβ25-35 injection) can block the damaging effects induced by Aβ and neuronal damage, improve the spatial learning and memory abilities of rats, and reverse the decrease in α-KGDHC enzyme activity[2].
Succinyl phosphonate (1 mg/kg; i.c.v.; single injection) reduces LPS (HY-D1056)-induced hippocampal mitochondrial protein succinylation, including succinylation of SDHA and ECHA, in male C57BL/6J mice[3].

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.
