Novel compounds useful as hypotensive agents are presented having the general formula I ##STR1## wherein R.sub.1 represents a substituted or unsubstituted aralkyl group, that is an aralkyl group of the general formula ##STR2## wherein R.sub.2 represents hydrogen, a lower alkyl group or a halogen atom. Furthermore, new therapeutic compositions of matter are also described incorporating the above novel 3-substituted-2(1H)pyridone-6-carboxylic acids (I) as an active ingredient with carriers and showing uses as hypotensive agents. These new compounds of the formula I are prepared by reacting D-glucaro-.delta.-lactam or its salt with an aralkyl halide.
