Résumé
To be able to understand the mechanisms of action of drugs, predict their efficacy, and anticipate their potential side-effects is important during drug development. In diseases where the genetic background of patients modulates treatment response, it might allow personalizing the therapy.
Substantial progress in proteomic technologies[1] have made it possible to develop chemical proteomics methods, where the protein targets of a drug are affinity-purified and identified by mass spectrometry[2, 3]. Compound-protein interactions are measured in a biological context as opposed to in vitro binding assays. That is, drugprotein interactions can not only be determined proteome-wide, but also in a tissue- or cell type-dependent manner.
