  Bentos,Kakenyaku Kako,Japan,1983

• Verwenden

  β-Adrenergic blocker used as antiglaucoma agent in ophthalmie solutions

• Verwenden

  Befunolol is a β-adrenergic blocker with an intrinsic sympathomimetic action. But it can work as a β-adrenergic partial agonist in isolated organs.

• Definition

  ChEBI: Befunolol is a member of benzofurans.

• Manufacturing Process

  To 8.8 g of 2-acetyl-7-hydroxybenzofuran were added 80 ml of epichlorohydrin and 0.2 g of piperidine hydrochloride and the mixture was heated at 105°C for 3 hours. After the reaction, the excess of epichlorohydrin was evaporated and the resultant was distilled under reduced pressure to give 9.3 g of 2-acetyl-7-(2,3-epoxypropoxy)benzofuranhaving a boiling point of 175° to 176°C/0.7 mm Hg. 6 g of the product was dissolved in 30 ml of ethanol and to the solution was added 10 ml of isopropylamine. After refluxing the mixture for 40 minutes, the solvent was evaporated from the reaction mixture. The resulting residue was recrystallized from cyclohexane-acetone to give 6 g of 2-acetyl-7-(2-hydroxy-3-isopropylaminopropoxy)benzofuran having a melting point of 115°C.

• Therapeutic Function

  Beta-adrenergic blocker

• Kontakt-Allergie

  Befunolol was implicated in allergic contact dermatitis due to beta-blocker agents in eye-drops. Crosssensitivity has been described with levobunolol.
