    摘要: A phosphinic acid derivative represented by the general formula [I], or a pharmaceutically acceptable salt thereof, ##STR1## wherein R.sup.1 represents an alkyl, cycloalkyl or aralkyl group which may be substituted; R.sup.2 and R.sup.5 may be identical or different, and each represents a hydrogen atom, or an ester residue capable of forming a non-toxic ester hydrolyzable in vivo; and A represents a group of the formula ##STR2## wherein R.sup.3 represents an alkyl group, a group of the formula ##STR3## wherein R.sup.30 represents a halogen atom, a carboxyl group, a hydroxyl group, a cycloalkyl group which may be substituted, an aryl group which may be substituted, an arylthio group, a heteroarylthio group which may be substituted, an alkylthio group which may be substituted, an amino group which may be substituted, or a lower alkoxycarbonyl group; R.sup.31 represents a hydrogen atom or a lower alkyl group; and n represents an integer of 0 to 6, a cycloalkyl group which may be substituted or an aryl group which may be substituted; and the double bond at A has a Z-configuration, or a group of the formula ##STR4## wherein R.sup.4 represents a cycloalkyl group which may be substituted. Said phosphinic acid derivative is useful for reducing renal toxicity induced by a carbapenem or penem antibiotic and for inhibiting dipeptidase.
