- 2-(3-Amino-2-hydroxy-propoxy)-mono-and diazines
-
Heterocyclic compounds of the formula STR1 wherein Het denotes optionally substituted pyridazinyl, pyrimidinyl, pyrazinyl or substituted pyridyl, R1 is hydrogen or methyl and R2 is lower alklyl, optionally substituted phenyl-lower alkyl, carboxy-lower alkyl or functionally modified carboxy-lower alkyl, their condensation products with aldehydes, ketones or carbonic acid and their N-oxides, which are valuable (cardioselective) β-receptor blocking agents, and/or (cardioselective) β-receptor-stimulants.
