An amino acid derivative of the general formula: wherein, R1? is a lower alkyl group and R11 is (wherein R111 is a lower alkyl group and n is an integer of 1 to 5) or a lower alkyl group which may be substituted by hydroxy group or methoxyethoxymethoxy group, or R1? and R11 are combinedly together with the adjacent nitrogen atom; R12 is a hydrogen atom, CnH2n+ 1-O-CO-(n is as defined above) or R13 is a lower alkyl group which may be substituted by substituent(s) selected from HOOC-(H?C)n-O-, R12-NH-(n and R12 are as defined above) and pyridyl group; X is-CH?-,-O-or-NH-and Y is-O-or-NH-; wherein (wherein Z is-O-,-S-,-S(O)-,-S(O)?-,-CH?-,-CH(OH)-,---,-NH-or and a and b are independently an integer of 1 to 4 and the total of a and b is not more than 5) ; R2 is an aralkyl group which may be substituted by lower alkyl group(s); R3 is a hydrogen atom or a lower alkyl group; R? is a lower alkyl group; and A is hydroxy group and B is a hydrogen atom, or A and B are carbonyl group combinedly together with the adjacent carbon atom, a pharmaceutically acceptable acid addition salt or an ester thereof is described. The compounds of the invention possess inhibitory activities against renin and are useful as an antihypertensive agent.
