Recebido em 12/1/10; aceito em 2/8/10; publicado na web em 16/11/10 COORDINATION OF METALS TO ANTIBIOTICS AS A STRATEGY TO COMBAT BACTERIAL RESISTANCE. Antibiotic resistance has been growing at an alarming rate and consequently the arsenal of effective antibiotics against Gram-negative and Gram-positive bacteria has dropped dramatically. In this sense there is a strong need to produce new substances that not only have good spectrum of activity, but having new mechanisms of action. In this regard, this paper emphasizes the coordination of metals to antibiotics as a strategy for reversing antibiotic resistance and production of new drugs, with a special focus on quinolones, fluoroquinolones, sulfonamides and tetracyclines.
