    • A phosphinic acid derivative represented by the general formula [I], or a pharmaceutically acceptable salt thereof,
      wherein R¹ represents an alkyl, cycloalkyl or aralkyl group which may be substituted; R² and R⁵ 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
      wherein R³ represents an alkyl group, a group of the formula
      wherein R³⁰ 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; R³¹ 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
      wherein R⁴ 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.
