The increasing frequency of nosocomial infections due to multi-resistant pathogens exerts a significant toll and calls for novel and better antibiotics. Different approaches can be used in the search for novel antibiotics acting on drug-resistant bacterial pathogens. We present some considerations on valid bacterial targets to be used for searching new antibiotics, and how the information from bacterial genome sequences can assist in choosing the appropriate targets. Other factors to, be considered in target selection are the chemical diversity available for screening and its uniqueness. We will conclude discussing our strategy for searching novel antibacterials. This is based on a large collection of microbial extracts as a source of chemical diversity and on the use of specific targets essential for the viability of bacterial pathogens. Two assay strategies have been implemented: a pathway-based assay, where a series of essential bacterial targets is screened. in a single assay; and a binding assay, where many targets can be screened individually in the same format.
