Compounds of formula I
wherein
R is alkyl, alkenyl, cycloalkyl, cycloalkylalkyl or optionally
substituted aryl, aralkyl or aralkenyl,
R is hydrogen or a substituent,
R2 is hydrogen or has the significance indicated above for R,
A is alkylene,
X is a bond or imino,
Y is an oxygen or a sulfur atom and either Z is an oxygen
atom and n is 2 or 3 or Z is a bond and n is 1, 2 or 3, with the
proviso that when R2 is cycloalkylalkyl, R is alkyl and X is a bond then R1 is other than hydrogen, or aphysiologically acceptable hydrolyzable derivative thereof having the hydroxy group in the 2 position of the 3-aminopropoxy side chain in esterified form,
in free form or in salt form.
These compounds are useful as cardioselective betaad- renoreceptor blocking agents.
