Synthesis and irreversible beta-adrenergic blockade with a bromoacetamido derivative of betaxolol.

Abstract:

:1-[4-(2-Cyclopropylmethoxyethyl)phenoxy]-3-[1-p-(bromoacetamidophe nyl) -2-methyl-2-propylamine]-2-propranol (8), which is a derivative of the beta 1-adrenergic agent betaxolol, was synthesized. Compound 8 showed less potent beta-adrenergic blocking activity than betaxolol in an in vitro test with guinea pig tracheal muscle and left atrium but retained high beta 1-selectivity. Irreversible beta-adrenoceptor antagonism of 8 was assessed by the blockade of the isoproterenol response of the guinea pig atria and by ligand binding studies with rat cerebral cortex.

  • Determination of pindolol in biological fluids by electron-capture GLC.

    abstract::An electron-capture GLC method was developed for measuring pindolol in human plasma and urine. The unchanged drug was extracted with benzene from alkalinized plasma or urine using propranolol as the internal standard. Both compounds subsequently were back-extracted into 0.1 M HCl and then into benzene. After evaporati...
