Certain 1-amino-3-(1-isoquinolinyl)oxy-2-propanol derivatives

Abstract

This invention provides compounds of formula I, ##STR1## wherein R is alkyl of 3 to 7 carbon atoms; cycloalkyl of 3 to 7 carbon atoms; cycloalkyl of 3 to 7 carbon atoms monosubstituted with alkyl of 1 to 4 carbon atoms; .alpha.-dialkylpropinyl of 5 to 9 carbon atoms; .alpha.-dialkylallyl of 5 to 9 carbon atoms; hydroxyalkyl of 2 to 7 carbon atoms, the hydroxy group thereof being separated by at least two carbon atoms from the nitrogen atom to which R is bound; phenethyl; phenethyl mono- or disubstituted in the phenyl residue independently when di-substituted with halogen of atomic number from 9 to 35, alkyl of 1 to 4 carbon atoms or unbranched alkoxy of 1 to 4 carbon atoms; or adamantyl; and Either R.sub.1 is phenyl and R.sub.2 is hydrogen; Or R.sub.1 is alkyl of 1 to 4 carbon atoms or halogen of atomic number from 9 to 35 and R.sub.2 is unbranched alkoxy of 1 to 4 carbon atoms or halogen of atomic number from 9 to 35, with the general proviso that the 8-position of the isoquinoline is unsubstituted and any halogen substituent which may be present in the 3- or 4- position is other than fluorine, Useful for treating coronary diseases, arrhythmia, hyperlipoidemia and hyperglycemia.
