Processes for their preparation and their use in the treatment of disorders mediated by the neuropeptide Y5 receptor in a warm-blooded animal, such as a human being are also described.
The synthesis of a series of 1-phenoxy-3-[[(substituted-amido)alkyl]amino]-2-propanols is described. Many of the compounds are more potent than propanolol as beta blockers, while having cardioselectivity comparable to that of practolol, when given intravenously to anesthetized cats. The structure-activity relationships shown by this series of compounds provide further evidence that the addition of substituents to the alkylamino moeity of a beta blocker can confer cardioselectivity and that amidic substituents are remarkably effective.
