A method for alleviating hypertension in hypertensive mammals which comprises administering an effective dose of a compound having the formula ##STR15## or salt thereof, wherein R is hydroxy or lower alkoxy R 1 is hydrogen, lower alkanoyl or amino(imino)methyl; R 2 is hydrogen, lower alkyl or phenyl-lower alkylene; R 3 is hydrogen, lower alkanoyl, benzoyl or ##STR16## A is hydrogen, lower alkyl or hydroxy-lower alkylene; B is hydrogen, lower alkyl, phenyl, phenyl-lower alkylene, hydroxy-lower alkylene, hydroxyphenyl-lower alkylene, amino-lower alkylene, guanidino-lower alkylene, imidazolyl-lower alkylene, indolyl-lower alkylene, mercapto-lower alkylene, lower alkylthio-lower alkylene, carbamoyl-lower alkylene or carboxy lower alkylene; or A and B together form a (CH 2 ) p bridge which completes an unsubstituted ring of 5 or 6 atoms with the nitrogen and carbon to which they are joined or said ring substituted with a hydroxy group; m is 1, 2, 3 or 4; n is 0 or 1; and p is 3 or 4.
