title: Potential inhibitors of tyrosine hydroxylase and dopamine-beta-hydroxylase.
abstract: A series of methyl-substituted 1,2,3,4-tetrahydrocarbazoles was synthesized and screened for in vitro activity against tyrosine hydroxylase and dopamine-beta-hydroxylase. The most potent compounds were evaluated for inhibition of norepinephrine biosynthesis in rats. The results indicated no significant decrease in norepinephrine levels at three dosage levels.
