• Verwenden

  Anti-inflammatory glucocorticoid related to Enoxolone. Antiulcerative

• Verwenden

  beta-adrenergic agonist, growth stimulant

• Verwenden

  Carbenoxolone is anti-inflammatory. It is often used as a gap junction inhibitor in neuroscience research. Carbenoxolone is also an inhibitor of the steroid dehydrogenase enzymes 11 β-hydroxysteroid dehydrogenase (human) and 3α, 20 β-hydroxysteroid dehydrogenase (bacterial). It is used for the treatment of digestive tract ulcers, especially in the stomach. Used in the treatment of peptic, mainly gastric, ulcers. It is often used as a gap junction inhibitor in neuroscience research.

• Definition

  ChEBI: Carbenoxolone sodium is a triterpenoid.

• Manufacturing Process

  23.5 g of glycyrrhetinic acid were dissolved in 50 cc of dry pyridine. A solution of 6.0 g of succinic anhydride in 30 cc of dry pyridine was added, followed by 30 cc of dry triethylamine and then, for washing purposes, 5 cc of dry pyridine. The solution was heated on a boiling water bath for ten hours and then poured into excess of dilute hydrochloric acid and ice. The fine gray precipitate formed was filtered off, washed with water, dissolved in chloroform, and the solution repeatedly extracted with dilute hydrochloric acid and later with water. It was dried over sodium sulfate and evaporated to dryness. Crystallization from methanol, using charcoal to effect decolorization, gave the hydrogen succinate as cream-colored crystals, MP 291° to 294°C, with previous softening.
  One molecular proportion of glycyrrhetinic acid hydrogen succinate was ground with a dilute (5%) aqueous solution containing two molecular proportions of sodium hydroxide. The solution was filtered and evaporated in vacuum over concentrated sulfuric acid. The sodium salt is then obtained as a creamy white water-soluble solid. Glycyrrhetinic acid is obtainable from licorice root.

• Therapeutic Function

  Antiinflammatory (gastric)

• Allgemeine Beschreibung

  Carbenoxolone disodium is a water soluble disodium salt of glycyrrhetinic acid hemisuccinate. It acts as an efficient promoter for the nasal absorption of insulin.

• Biologische Aktivität

  Glucocorticoid that inhibits 11 β -hydroxysteroid dehydrogenase (11-HSD) and blocks gap juntion communication.

• Lager

  Store at +4°C
