Abstract
Based on the mode of action of antibacterial drugs currently used, targets can be defined as distinct cellular constituents such as enzymes, enzyme substrates, RNA, DNA, and membranes which exhibit very specific binding sites at the surface of these components or at the interface of macromolecular complexes assembled in the cell. Intriguingly, growth inhibition or even complete loss of bacterial viability is often the result of a cascade of events elicited upon treatment with an antibacterial agent. In addition, their mode of action frequently involves more than one single target. A comprehensive description of the targets exploited so far by commercialized antibacterial agents, including anti-mycobacterial agents, is given. The number of targets exploited so far by commercial antibacterial agents is estimated to be about 40. The most important biosynthetic pathways and cellular structures affected by antibacterial drugs are the cell wall biosynthesis, protein biosynthesis, DNA per se, replication, RNA per se, transcription and the folate biosynthetic pathway. The disillusionment with the genomics driven antibacterial drug discovery is a result of the restrictive definition of targets as products of essential and conserved genes. Emphasis is made to not only focus on proteins as potential drug targets, but increase efforts and devise screening technologies to discover new agents interacting with different RNA species, DNA, new protein families or macromolecular complexes of these constituents.

"Tuberculosis Prevention, Diagnosis and Drug Discovery"
The Nobel Prize-winning discoveries of Mycobacterium tuberculosis and streptomycin have enabled an appropriate diagnosis and an effective treatment of tuberculosis (TB). Since then, many newer diagnosis methods and drugs have been saving millions of lives. Despite advances in the past, TB is still a leading cause of infectious disease mortality ...read more
Blood-based biomarkers in large-scale screening for neurodegenerative diseases
Disease biomarkers are necessary tools that can be employ in several clinical context of use (COU), ranging from the (early) diagnosis, prognosis, prediction, to monitor of disease state and/or drug efficacy. Regarding neurodegenerative diseases, in particular Alzheimer’s disease (AD), a battery of well-validated biomarkers are available, such as cerebrospinal fluid ...read more
