Teprenone Chemische Eigenschaften,Einsatz,Produktion Methoden

• Beschreibung

  Teprenone (geranylgeranylacetone) is an antiulcer agent whose synthesis was inspired by the gastric protecting properties of Coenzyme Q10. Teprenone is reported to act via enhancement of gastric mucosal glycoprotein secretion.

• Beschreibung

  Geranylgeranylacetone is an inducer of heat shock protein (Hsp) expression that has been shown to increase Hsp70 (also known as Hsp72 and HspA1A), Hsp22 (HspB8), Hsp27 (HspB1), Hsp90 (HspC), and Hsp105 (HspH1) levels in various cells and tissues. It is orally bioavailable and has diverse effects in vivo, including hepatoprotective, neuroprotective, and antiulcerative effects. The effects of geranylgeranylacetone on Hsp expression are more pronounced under stress conditions.

• Verwenden

  An anti-ulcerative. Geranylgeranylacetone can induce expression of HSP70, HSPB8, and HSPB1. Induction of HSP70 expression is protective against the development of various diseases, such as inflammatory bowel disease, hypoxic/ischemic brain injury and spinal and bulbar muscular atrophy (cytoprotective and anti-inflammatory effects). Reports indicate that GGA protects against NSAID-induced gastric and intestinal lesions by induction of HSP70 expression. Other studies have shown that GGA induces expression of HSPB8 and HSPB1 and reduces the formation of amyloid oligomers as well as insoluble aggregates in HSPB5 R120G TG mice.

• Verwenden

  Geranylgeranylacetone has been used as an inducer of heat shock protein 70 (HSP70) to analyze its protective effects against cerebral ischemia/reperfusion (I/R).

• Definition

  ChEBI: A terpene ketone in which a (9E,13E)-geranylgernayl group is bonded to one of the alpha-methyls of acetone (it is a mixture of 5E- and 5Z-geoisomers in a 3:2 ratio).
