Novel Pyrimidines as Antitubercular Agents.

abstract：:OXA-48-like carbapenemases have only recently emerged in Europe. OXA-162 is a rare OXA-48 variant usually coexpressed with extended-spectrum β-lactamases. Here, we report the identification of the first OXA-162 carbapenemase-producing Klebsiella pneumoniae isolates, which coexpressed an AmpC cephalosporinase (DHA-1), ...
