Mass spectrometry offers the potential of acquiring high resolution data depicting the functional status of a group of healthy or diseased individuals, according to different conditions. As most of the drugs are currently targeting proteins, proteomics has a dual value, both in the discovery of new molecules as therapeutic targets, but also as a methodology to perform high throughput drug profiling. As there is an evident need for drugs to be improved in terms of efficacy, a mechanistic insight for downstream effectors can be valuable in order to predict side effects and resistance mechanisms. Recently developed assays, like thermal proteome profiling enables comprehensive drug target profiling and is, therefore, of high value in drug discovery. In this review, a systematic literature search is conducted and the most prominent proteomics studies as implicated in assisting drug discovery and development is presented. Focus is placed on investigations that are closer to implementation, therefore particular emphasis is given in studies conducted in human diseased population and further verified in vitro or in vivo.
