Soft tertiary amine esters of bio-affecting carboxylic acids, processes for preparing and a pharmaceutical composition containing the same.

摘要

Derivatives of known bio-affecting carboxylic acids, their non-toxic pharmaceuticaily acceptable acid addition salts and N-oxides as well as processes for preparing those novel derivatives are disclosed. Those derivatives having the structural formula
<CHEM>
wherein R-COO- is the acyloxy residue of a bio-affecting monocarboxylic acid;
Y and Y min are each hydrogen or alkyl; n is zero or one;
R1 and R2 are each inter alia alkyl, alkenyl, aryl, cycloalkyl, cycloalkenyl, aralkyl or alkaryl; and R3 is inter alia hydrogen; or the structural formula
<CHEM>
wherein -OOC-R min -COO- is the di(acyloxy) residue of a bio-affecting dicarboxylic acid.
