Development of novel antibacterial agents against methicillin-resistant Staphylococcus aureus
摘要:
Methicillin-resistant Staphylococcus aureus (MRSA) poses a serious threat to public health because of its resistance to multiple antibiotics most commonly used to treat infection. In this study, we report the unique ability of the cyclooxygenase-2 (COX-2) inhibitor celecoxib to kill Staphylococcus aureus and MRSA with modest potency. We hypothesize that the anti-Staphylococcus activity of celecoxib could be pharmacologically exploited to develop novel anti-MRSA agents with a distinct mechanism. Examination of an in-house, celecoxib-based focused compound library in conjunction with structural modifications led to the identification of compound 46 as the lead agent with high antibacterial potency against a panel of Staphylococcus pathogens and different strains of MRSA. Moreover, this killing effect is bacteria-specific, as human cancer cells are resistant to 46. In addition, a single intraperitoneal administration of compound 46 at 30 mg/kg improved the survival of MRSA-infected C57BL/6 mice. In light of its high potency in eradicating MRSA in vitro and its in vivo activity, compound 46 and its analogues warrant continued preclinical development as a potential therapeutic intervention against MRSA.

Methods of treating bacterial infection by in a subject by administering a pharmaceutical composition including a celecoxib derivative are described. The compounds are particularly useful for treating infection by bacteria capable of growing inside macrophages, such as
Myocobacteria tuberculosis.

A method of treating infection by Staphylococcus in a subject by administering a pharmaceutical composition including a celecoxib derivative of formula I or a pharmaceutically acceptable salt thereof is described. The preparation of numerous celecoxib derivatives for testing as potential anti-staphylococcal agents is also described.
