Abstract
Abstract Biologically active derivatives of norepinephrine are disclosed. Such derivatives are catecholamines wherein isoproterenol is modified by extending the isopropyl functional grouping to an alkyl, aryl, or alkyl-aryl chain of variable length where said chain terminates in a carboxylic acid functional group, or in a substituted amide functional group. Such derivatives are beta -adrenergic and a number of such derivatives e.g., 6-( beta -3,4-dihydroxyphenyl- beta -hydroxy)-ethylamino heptanoic acid p-toluide, 6-( beta -3,4-dihydroxyphenyl- beta -hydroxy)-ethylamino heptanoic acid para-n-butyl anilide; 6-( beta ,3,4-dihydroxyphenyl- beta -hydroxy)-ethylamino heptanoic acid para-methoxy anilide; 6-( beta -3,4-dihydroxyphenyl- beta -hydroxy)-ethylamino heptanoic acid paratrifluoromethyl anilide; and 6-( beta -3,4-dihydroxyphenyl- beta -hydroxy)-ethylamino heptanoic acid N-methyl para-toluide display a beta -adrenergic activity at least several orders of magnitude greater than isoproterenol itself. Several methods of producing such active derivatives are also disclosed.
