Streptococcus pneumoniaecauses bacterial pneumonia with high mortality and morbidity. The emergency of multidrug-resistant bacteria threatens the treatment of the disease. Leucyl-tRNA synthetase (LeuRS) plays an essential role in cellular translation and is an attractive drug target for antimicrobial development. Here we report the compound ZCL039, a benzoxaborole-based derivative of AN2690, as a potent anti-pneumococcal agent that inhibitsS. pneumoniaeLeuRS (SpLeuRS) activity. We show using kinetic, biochemical analyses combined with the crystal structure of ZCL039-AMP in complex with the separatedSpLeuRS editing domain, that ZCL039 binds to the LeuRS editing active site which requires the presence of tRNALeuand employs an uncompetitive inhibition mechanism. Further docking models establish that ZCL039 clashes with the eukaryal/archaeal specific insertion I4ae helix within editing domains. These findings demonstrate the potential of benzoxaboroles as effective LeuRS inhibitors for pneumococcus infection therapy and provide future structure-guided drug design and optimization.
