Abstract
Benzyloxyamine derivatives have been shown to be inhibitors of the enzyme dopamine-β-oxidase by virtue of their isosteric relationship to the corresponding phenethylamine derivatives. Benzyloxyamine and two hydroxylated analogues were shown to inhibit the enzyme by a mechanism which is initially competitive with substrate. However, when preincubated with the enzyme the compounds become so firmly bound that substrate cannot readily reverse the inhibition. Although preincubation results in a non-competitive type of inhibition the inhibitor-enzyme complex can, in many instances, be dissociated by prolonged dialysis.
