Résumé

The global emergence of multi-drug resistant bacteria invokes an urgent and imperative necessity for the identification of novel antimicrobials. The general lack of success in progressing novel chemical entities from target-based drug screens have prompted calls for radical and innovative approaches for drug discovery. Recent developments in chemical biology and target deconvolution strategies have revived interests in the utilization of whole-cell phenotypic screens and resulted in several success stories for the discovery and development novel drug candidates and target pathways. In this review, we present and discuss recent chemical biology approaches focusing on the discovery of novel targets and new lead molecules for the treatment of human bacterial and protozoan infections.

Drug discovery

In the fields of medicine, biotechnology and pharmacology, drug discovery is the process by which new candidate medications are discovered. Historically, drugs were discovered by identifying the active ingredient from traditional remedies or by serendipitous discovery, as with penicillin. More recently, chemical libraries of synthetic small molecules, natural products or extracts were screened in intact cells or whole organisms to identify substances that had a desirable therapeutic effect in a process known as classical pharmacology.

Conception de médicament

La conception de médicament, plus précisément conception de substance pharmacologiquement active plus connue sous sa dénomination anglaise Drug design est l'ensemble des processus nécessaires à l'élaboration d'un médicament. Dans l'industrie pharmaceutique, ces processus peuvent-être subdivisés et répartis en quatre phases ou étapes : La phase de recherche La phase de développement La phase clinique La phase de mise sur le marché Remarque : Les phases de recherche et développement sont communément dénommées R&D.

Phenotypic screening

Phenotypic screening is a type of screening used in biological research and drug discovery to identify substances such as small molecules, peptides, or RNAi that alter the phenotype of a cell or an organism in a desired manner. Phenotypic screening must be followed up with identification (sometimes referred to as target deconvolution) and validation, often through the use of chemoproteomics, to identify the mechanisms through which a phenotypic hit works. Phenotypic screening historically has been the basis for the discovery of new drugs.
