Regulation of stress-induced cytokine production by pyridinylimidazoles; inhibition of CSBP kinase
摘要:
Members of three classes of pyridinylimidazoles bind with varying affinities to CSBP (p38) kinase which is a member of a stress-induced signal transduction pathway. Based upon SAR and protein homology modeling, the pharmacophore and three potential modes of binding to the enzyme are presented. For a subset of pyridinylimidazoles, binding is shown to correlate with inhibition of CSBP kinase activity, whereas no significant inhibition of PKA, PKC alpha and ERK kinase activity is observed.

We disclose herein that the BlaR1 protein of methicillin-resistant
Staphylococcus aureus
(MRSA), an antibiotic sensor/signal transducer, is phosphorylated on exposure to β-lactam antibiotics. This event is critical for the onset of the biochemical events that unleash induction of antibiotic resistance. The BlaR1 phosphorylation and the antibiotic-resistance phenotype are abrogated in the presence of inhibitors described herein that restore susceptibility of the organism to β-lactam antibiotics. The invention thus provides compounds and methods for abrogating antibiotic resistance to β-lactam antibiotics and for treating infections causes by antibiotics prone to developing resistance.
