Pneumonia
caused by bacterium S. pneumoniae is a severe acute respiratory infectious disease with high morbidity and mortality, especially for children and immunity-compromised patients. The emergence of multidrug-resistant S. pneumoniae also presents a challenge to human health.
Leucyl-tRNA synthetase
(
LeuRS
) catalyzes the attachment of l-leucine to tRNA
Leu
, which plays an essential role in protein translation and is considered an attractive antimicrobial drug target. In the present work, benzhydrol-oxaborole hybrid compounds were designed and synthesized as inhibitors of S. pneumoniae
LeuRS
. Exploration of the phenyl ring near Lysine 389 eventually yielded compounds 46 and 54 with submicromolar inhibitory potency. The co-crystal of compound 54 in the editing domain pocket of SpLeuRS was obtained and confirmed the formation of an additional hydrogen bond between the carbonyl of 54 and Lysine 389. It also showed anti-pneumococcal activity in vitro. The structure-activity relationship was discussed. This work will provide an essential foundation for the further development of anti-pneumococcal agents by targeting
