An aminocarboxylic acid derivative represented by the formula ##STR1## wherein R.sub.1 and R.sub.2, independently from each other, represent a hydrogen atom or an alkyl group which may have a substituent, and Y represents --NH-- or --S--, provided that when Y represents --NH--, at least one of R.sub.1 and R.sub.2 represents an alkyl group which may have a substituent. These compounds have excellent inhibitory activity on dipeptidase in animals, and are useful for administration in combination with carbapenem antibiotics.
由以下公式表示的氨基羧酸衍生物##STR1##其中R.sub.1和R.sub.2独立地代表氢原子或可能具有取代基的烷基基团,Y代表--NH--或--S--,但当Y代表--NH--时,至少一个R.sub.1和R.sub.2代表可能具有取代基的烷基基团。这些化合物在动物体内对二肽酶具有出色的抑制活性,并且可与碳青霉烯类抗生素联合使用。
