The present invention relates to methods of treating a disease related to cell hyper-proliferation via administration of a therapeutically effective amount of a compound having a general tripartite structure A-B-C. In the tripartite structure A, B, and C are identical or non-identical structures, for example, but not limited to, heterocyclic, phenyl or benzyl ring structures with or without substitutions and are described in detail herein. The methods may utilize particular compounds, for example, having a piperidinyl, a pyrrolinyl or pyridinyl A ring, a thiazole B ring, and a phenyl C ring which may be further substituted independently.

We disclose herein that the BlaR1 protein of methicillin-resistant Staphylococcus aureus (MRSA), an antibiotic sensor/signal transducer, is phosphorylated on exposure to -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 -lactam antibiotics. The invention thus provides compounds and methods for abrogating antibiotic resistance to -lactam antibiotics and for treating infections causes by antibiotics prone to developing resistance.
