Structural systems pharmacology offers a novel way of approaching drug discovery by considering the global physiological environment of protein targets, and the effects derived of tinkering with them, without losing the key molecular details. In this article, we review some recent advances in the structural annotation of cell networks and discuss their potential impact on some of the hottest areas of drug development. In particular, we analyze recent structure-based strategies to target networks, protein interaction interfaces and allosteric sites, and how they will help in the development of more potent and specific treatments. Finally, we propose that mapping genetic variations onto protein networks, beyond the pharmacological targets, can rationalize interindividual variability in drug response, giving valuable hints to advance toward personalized medicine.
