Metallo-β-lactamase inhibitory activity of 3-alkyloxy and 3-amino phthalic acid derivatives and their combination effect with carbapenem

Hiraiwa, Yukiko,Morinaka, Akihiro,Fukushima, Takayoshi,Kudo, Toshiaki

, p. 5841 - 5850 (2013/09/12)

3-Alkyloxy and 3-amino phthalic acid derivatives were found to have metallo-β-lactamase inhibitory activity. Among them, 3-amino phthalic acid derivatives showed both potent activity against metallo-β-lactamase, IMP-1 inhibitory activity and a strong combination effect with biapenem (BIPM), carbapenem antibiotic. In particular, the 4′-hydroxy-piperidine derivative showed strong IMP-1 inhibitory activity and a combination effect with various antibiotics.
