Beschreibung
Spermine is an endogenous polyamine synthesized from the reaction of spermidine with decarboxylated S-adenosylmethionine in the presence of the enzyme spermine synthase and is required for eukaryotic cell growth and protein synthesis. Intracellular spermine blocks inward rectifying K⁺ channels, whereas extracellular spermine acts as a mixed NMDA glutamate receptor agonist/antagonist at the polyamine site. Spermine has neuroprotective and anti-inflammatory effects and functions as a free radical scavenger to prevent DNA damage by reactive oxygen species.
Chemische Eigenschaften
White to slightly off-white powder crysta
Verwenden
immune modulator
Verwenden
Biogenic polyamine formed from spermidine and occurring in almost all tissues. Essential for both normal and neoplastic tissue growth. Involved in the modulation of calcium-dependent immune processes
Verwenden
Binds to the polyamine modulatory site of NMDA Spermine is essential for both normal and neoplastic tissue growth. It is involved in the modulation of calcium-dependent immune processes. It plays an important role in cellular proliferation and differentiation as well as inhibits neuronal nitric oxide synthase (nNOS).
Definition
ChEBI: A polyazaalkane that is tetradecane in which the carbons at positions 1, 5, 10 and 14 are replaced by nitrogens. Spermine has broad actions on cellular metabolism.
Allgemeine Beschreibung
Spermine?is a polyamine, which functions as a free radical scavenger. It modulates gene expression, chromatin stabilization and prevents DNA damage. Spermine inhibits endonuclease-mediated DNA fragmentation.
Biochem/physiol Actions
Mixed NMDA glutamate receptor agonist/antagonist at the polyamine site. Neuroprotective effects have been observed at high concentrations (1 mM), while neurotoxicity is observed at lower concentrations. It enhances agonist effectiveness at the strychnine-insensitive glycine site. Plays a role in cellular proliferation and differentiation; inhibits neuronal nitric oxide synthase (nNOS).
