                            The present invention relates to an amino acid derivative represented by the formula ##STR1## wherein R.sub.1 and R.sub.2 represent hydroxyl, alkyloxy, aryloxy, arylkyloxy, alkyl, aryl, or aralkyl; R.sub.3, R.sub.5, R.sub.8 and R.sub.11 are hydrogen or alkyl; R.sub.4, R.sub.7 and R.sub.10 are hydrogen, or substituted or unsubstituted alkyl, aryl or aralkyl; R.sub.6 and R.sub.9 are hydrogen, alkyl, aryl, or aralkyl; R.sub.12 is hydroxyl, alkyloxy, aryloxy, aralkyloxy, amino, mono- or di-alkyl-, aryl- or aralkyl amino; and R.sub.6 and R.sub.7 combined together, and R.sub.9 and R.sub.10 combined together independently may form a substituted or unsubstituted alkylene bridge. The present invention also relates to a method of preparing said amino acid derivatives, and to anti-hypertensive drugs containing them.
