ine were prepared and evaluated as inhibitors of norepinephrine N-methyltransferase (NMT). These included several alkyl side chain extended analogues (1-5), as well as the terminally hydroxylated derivatives phenylalanol (6a) and phenylglycinol (7a). None of the alkyl-substituted derivatives displayed appreciable activity as inhibitors; however, the hydroxylated analogues were up to twofold more potent
