摘要:
The present invention is directed to the use of RecA inhibitors as antibiotic agents, and provides RecA inhibitors useful in treating infections. Also provided are various compositions and methods associated with RecA inhibition.
摘要:
The present invention provides methods for identifying target genes whose partial or complete functional inactivation potentiates the activity of an antibiotic agent, e.g., a quinolone antibiotic. The invention further provides methods for identifying agents that modulate expression of target genes or that modulate activity of expression products of target genes. Agents identified according to various methods of the invention potentiate the activity of antibiotics such as quinolones, aminoglycosides, peptide antibiotics and β-lactams. Also provided are agents that suppress and/or retard resistance to antibiotics. The inventive methods provide potentiating agents and compositions comprising potentiating agents and antibiotics. Such agents and compositions can be used for inhibiting growth or survival of a microbial cell or of treating a subject suffering from or susceptible to a microbial infection.

摘要:
The present invention provides compounds that potentiate the activity of antibiotic agents, particularly quinolones such as norflaxin. The invention further provides compositions, e.g., pharmaceutical compositions, comprising the inventive compounds. The invention also provides compositions comprising an antibiotic (e.g., a quinolone) and a compound that potentiates activity of the antibiotic. The invention further provides methods of treating a subject comprising administering any of the inventive compounds or compositions to the subject. The invention also provides screening methods to identify compounds that potentiate the activity of an antibiotic, e.g., a quinolone.
摘要:
A pharmaceutical composition comprising an antimicrobial agent and an enhancer of an antimicrobial agent, wherein the enhancer of an antimicrobial agent is an inhibitor of gene, that by inactivating the gene product potentiates the effectiveness of the antimicrobial agent. In some embodiments, the pharmaceutical composition further comprises a pharmaceutically acceptable carrier. In some embodiments, the antimicrobial agent is an antimicrobial peptide such as a polymyxin, for example but not limited to colistin. In some embodiments of the present invention provides methods to treat and/or prevent infection of a subject with a microorganism by administering a pharmaceutical composition comprising an antimicrobial agent and an enhancer of an antimicrobial agent. In some embodiments, the present invention provides methods to inhibit growth of a microorganism by administering a pharmaceutical composition comprising an antimicrobial agent and an enhancer of an antimicrobial agent.
