title: (RS), (R)(-) and (S)(+) derivatives of 2-N-arylalkylamino-1-butanol having antiarrhythmic properties.
abstract: A series of theophyllinyl-7'-ethyl derivatives of (RS), (R)(-) and (S)(+) 2-aminobutanol were synthesized and tested in various models of experimental arrhythmia for their preventive and curative properties; (R)(-) 2-N-theophyllinyl-7'-ethyl amino-1-butanol (1a) and (R)(-) theophyllinyl-7'-ethyl-2-N-methylamino-1-butanol (3a) hydrochlorides showed interesting antiarrhythmic properties. The levorotatory compounds of R configuration showed stronger protective and also therapeutic effect in different experimental arrhythmias.
