ISOPIMARIC ACID Chemische Eigenschaften,Einsatz,Produktion Methoden

Beschreibung
Isopimaric acid (5835-26-7) is a terpenoid acid that activates BK (voltage-gated potassium) channels when used at 10 μM in HEK293 cells.1 Improves spatial and non-spatial memory in Alzheimer’s mouse model2,3, and significantly improves motor function in a rat spinal cord injury model4. Reduces hyperactivity of spontaneously active auditory networks, EC50=7.8 μM.5
Verwenden
A potent novel activators of large-conductance Ca2+-activated K+ channel.
Definition
ChEBI: Isopimaric acid is a diterpenoid, a carbotricyclic compound and a monocarboxylic acid. It is a conjugate acid of an isopimarate. It derives from a hydride of an isopimara-7,15-diene.
Allgemeine Beschreibung
Isopimaric acid, a resin acid produced by conifer trees, is a tricyclic diterpene compound. High levels of isopimaric acid in the hepatocytes of the rainbow trout may impair calcium signalling machinery. Isopimaric acid is a potential big potassium (BK) channel opener.
Biochem/physiol Actions
Potent opener of large conductance calcium activated K+ (BK) channels.
