Abstract
1. Methylation of tryptamine in the 1-position had little effect on the potency of the drug as a pressor agent in the intact anaesthetized rat. 2. In contrast, substitution of a benzo[b]thiophene ring system for the indole ring decreased the pressor activity. 3. Pretreatment of the animals with reserpine reduced the pressor effect of tryptamine and its benzo[b]thiophene analogue while increasing the effect of the 1-methylindole analogue. 4. Pretreatment with phenoxybenzamine reduced the pressor effect of all three compounds.
