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
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.
