Abstract
Bisphenoxy carboxylic acid derivatives useful as an antiarteriosclerosis agent with good absorbability and low toxicity, which are novel compounds represented by the general formula, ##STR1## wherein R.sub.1 and R.sub.2 represent hydrogen atoms or lower alkyl groups and A preresents ##STR2## (wherein in case R.sub.3 is a hydrogen atom, R.sub.4 represents an amino-lower-alkyl group, an N-lower-alkylaminoalkyl group, a heterocyclic group, or a heterocyclic group-substituted alkyl group; or R.sub.3 and R.sub.4 may join through an intermediary hetero atom to form a heterocyclic group and if said hetero atom is a nitrogen atom, this nitrogen atom can bear a lower alkyl group as a substituent) or ##STR3## (wherein R.sub.5 represents a hydrogen atom, a hydroxyalkyl group or a derivative thereof, and R.sub.6 represents a hydroxyalkyl group or a heterocyclic group; or R.sub.5 and R.sub.6 may join to form a cyclic group, or may join through another intermediary hetero atom to form a heterocyclic group and if said hetero atom is a nitrogen atom, this nitrogen atom can bear a lower alkyl group as a substituent).
