ABSTRACT:
A 5-substituted amino-4-hydroxy-pentenoic acid or its salt represented by the formula: ##STR1## wherein each of R.sup.1 and R.sup.2 which may be the same or different is a hydrogen atom, a lower alkyl group, an aralkyl group, a lower alkoxycarbonyl group, an aryloxycarbonyl group, an aralkyloxycarbonyl group or a lower alkanoyl group which may be substituted by from one to three substituents selected from the group consisting of an amino group, a hydroxyl group, a carboxyl group, an aryloxy group, an aralkyloxycarbonylamino group, a lower alkoxycarbonylamino group and a ##STR2## group (wherein each of X.sup.1 and X.sup.2 which may be the same or different is a hydrogen atom, a lower alkyl group, an aryl group or an aralkyl group, or X.sup.1 and X.sup.2 form together with the adjacent nitrogen atom a 5- or 6-membered heterocyclic group which may further contain a hetero atom selected from the group consisting of a nitrogen atom, an oxygen atom and a sulfur atom) and which may further contain a double bond in its carbon chain, each of R.sup.3, R.sup.4 and R.sup.6 which may be the same or different is a hydrogen atom, a lower alkyl group, a cycloalkyl group, a cycloalkylalkyl group, an aryl group, an aralkyl group or a residue of an acidic neutral or basic amino acid, R.sup.5 is a hydrogen atom or a lower alkyl group, R.sup.7 is a hydrogen atom, a lower alkyl, cycloalkyl, cycloalkylalkyl or aralkyl group which may be substituted by one or two hydroxyl groups or a residue of an acidic, neutral or basic amino acid, R.sup.8 is a hydroxymethyl group or a --CO--R.sup.9 group (wherein R.sup.9 is a hydroxyl group, a --OY group (wherein Y is a lower alkyl group, an aryl group, an aralkyl group, a lower alkoxyalkyl group, a lower alkanoyloxyalkyl group, a lower alkoxycarbonyloxyalkyl group, or a 1-phthalidyl group) or ##STR3## group (wherein each of Y.sup.1 and Y.sup.2 which may be the same or different is a hydrogen atom, a lower alkyl group, an aryl group, an aralkyl group or a cycloalkyl group, or Y.sup.1 and Y.sup.2 form together with the adjacent nitrogen atom a 5- or 6-membered heterocyclic group which may further contain a hetero atom selected from the group consisting of a nitrogen atom, an oxygen atom and a sulfur atom), and each of n and m which may be the same or different is 0 or 1.
