β-phenylethylamine can be viewed as the parent Compound of the sympathomimetic amines, consisting of a benzene ring and an ethylamine side chain. The structure permits substitutions to be made on the aromatic ring, the alpha- and β-carbon atoms, and the terminal amino group, to yield a great variety of Compounds with sympathomimetic activity. Norepinephrine, epinephrine, dopamine, dobutamine, dopexamine and isoproterenol have OH groups substituted in the 3 and 4 positions of the benzene ring. Since dihydroxybenzene is also known as catechol, sympathomimetic amines with these OH substitutions in the aromatic ring are termed catecholamines (fig 1).
