An organic carboxylic acid salt of 2-[(3S,4R)-1-[2-chloro-6-(trifluoromethyl)phenyl]methyl}-3-[1-(cyclohex-1-en-1-ylmethyl) piperidin-4-yl]carbamoyl}-4-methylpyrrolidin-3-yl]acetic acid and a crystal thereof.
A new metallo-β-lactamase inhibitor which acts as a medicament for inhibiting the inactivation of β-lactam antibiotics and recovering anti-bacterial activities is disclosed. The maleic acid derivatives having the general formula (I) have metallo-β-lactamase inhibiting activities. It is possible to recover the anti-bacterial activities of β-lactam antibiotics against metallo-β-lactamase producing bacteria by combining the compound of the general formula (I) with β-lactam antibiotics.
