..This commentary provides an overview of current antibiotic leads and their mechanism of action, and highlights tools that can be applied to the discovery of new antibiotics...

..7 and 61.6 mg/kg/day. BMS-284756 was more potent than levofloxacin and equipotent with moxifloxacin against ISP794 both in vitro and in vivo, while BMS-284756 was more potent than levofloxacin and moxifloxacin against 2C6(1)-1...

..In addition, areas for basic research and development included metallo-beta-lactamases, ribosomal structural studies and phage-selected targets were described...

..Among the leading development candidates are dalbavancin, oritavancin, telavancin and ramoplanin, each of which provides a unique microbiological and pharmacological profile to fill an important unmet medical need...

..The isolation, structure elucidation, antibacterial activity, and proposed biogenesis of thiazomycins are herein described...

..Despite its positive attributes, emergence of an unacceptable frequency of resistance poses significant challenges for further development of thiazomycin and this class of molecules for therapeutic use...

..7 microg/mL) and a potent Gram-positive antibacterial agent with minimum inhibitory concentration (MIC) ranging 0.002-0.25 microg/mL. The isolation and structure elucidation and biological activities of thiazomycin A are described...

..aureus. It exhibited a spectrum of antibacterial activity against clinically important pathogens including methicillin-resistant Staphylococcus aureus, Bacillus subtilis, and Haemophilus influenzae...

..The design and execution of the bioassay, the isolation, structure, in vitro and in vivo antibacterial activity, and docking studies of philipimycin and its degradation product are described...

..With the realization that MRSA is now a community problem, there are expanded efforts toward more direct intervention, such as the use of anti-MRSA antibacterials and vaccines, in an attempt to reduce the overall burden of MRSA...

..The isolation and structure elucidation of thiazomycin is herein described...

..g., host metabolism differences), safety and the microbial genesis of chronic diseases (e.g., gastric ulceration)...

..This decline in antibacterial drug discovery, coupled with increasing risk as a result of infections caused by drug-resistant bacterial pathogens, represents a clear public health threat...

..So this leaves one with the question of 'can biotech deliver the new antibiotics?'...

..e., spectrum, activity, resistance emergence, efficacy, target, safety) provide a basis for an emerging pharmacoeconomic-based distinction between these newer anti-Gram-positive agents...

..2 to 0.4 microg/ml. Furthermore, the effectiveness, selectivity, and the in vitro and in vivo correlations of BABX as well as other fatty acid inhibitors were elucidated, which will aid in future drug discovery...

..To this end, the authors outline a few ideas regarding the changes in approach in order to accomplish these needs, including a fundamental change in the drug discovery process...

..Within this overview, we provide a strategic overview of a sample process for the identification, validation and exploitation of novel antibacterial targets ascertained through a bioinformatics-based genomics drug discovery program...

....

..Although critical for certain resistance niche needs, these agents are unlikely to provide the solution to the requirement for a major novel scaffold class of antibacterials...

..The synthesis and antibacterial activity of three such ring systems, the benzisoxazolinones, pyrroles, and isoxazolinones is described...

..These compounds demonstrated potential for further development as a new class of antibacterial agents with activity against key antibiotic-resistant gram-positive bacterial pathogens...

..This work therefore demonstrates a streamlined process for proceeding from selection and validation of candidate antifungal targets to screening for specific inhibitors...

..The synthesis of homologated sordaricin as well as ether and ester derivatives is presented, and structural rearrangement products upon oxidation. These compounds were evaluated as agents to inhibit fungal growth...

..06 microg/mL. The antifungal activity was established to be exquisitely sensitive to the spatial orientation of the lipophilic side chains...

..Extensive investigation of various substitutions on the phenyl ring was then undertaken. We report here, the synthesis and antibacterial activity of a series of biaryl isoxazolinone compounds...
