Although mast cells have long been known to play a critical role in anaphylaxis and other allergic diseases, they also participate in some innate immune responses and may even have some protective functions. Data from the study of mast cell-deficient mice have facilitated our understanding of some of the molecular mechanisms driving mast cell functions during both innate and adaptive immune responses. This review presents an overview of the biology of mast cells and their potential involvement in various inflammatory diseases. We then discuss some of the current pharmacological approaches used to target mast cells and their products in several diseases associated with mast cell activation. © 2014 Elsevier Inc.

Docking is the computational method of choice to quickly predict how a low molecular-weight ligand binds to its macromolecular target. Despite persistent problems in predicting binding free energies, docking has undergone significant advances in numerous topics (throughput, target flexibility). The ever increasing availability of high-resolution X-ray structures and the development of more reliable comparative models for proteins of pharmacological interest paved the way to apply protein-ligand docking to multiple targets to predict main and off-targets for bioactive compounds and even to repurpose existing drugs. Applying docking to multiple targets brings an additional level of complexity in scoring numerous and heterogeneous docking poses. Despite undeniable successes, proteome-wide docking should, however, be considered with caution with regard to recall and precision of the predictions. © 2012 Elsevier Ltd. All rights reserved.

Fragment-based design has significantly modified drug discovery strategies and paradigms in the last decade. Besides technological advances and novel therapeutic avenues, one of the most significant changes brought by this new discipline has occurred in the minds of drug designers. Fragment-based approaches have markedly impacted rational computer-aided design both in method development and in applications. The present review illustrates the importance of molecular fragments in many aspects of rational ligand design, and discusses how thinking in "fragment space" has boosted computational biology and chemistry. © 2011 Springer-Verlag Berlin Heidelberg.

Inferring the biological function of a protein from its three-dimensional structure as well as explaining why a drug may bind to various targets is of crucial importance to modern drug discovery. Here we present a generic 4833-integer vector describing draggable protein-ligand binding sites that can be applied to any protein and any binding cavity. The fingerprint registers counts of pharmacophore triplets from the Ca atomic coordinates of binding-site-lining residues. Starting from a customized data set of diverse protein-ligand binding site pairs, the most appropriate metric and a similarity threshold could be defined for similar binding sites. The method (FuzCav) has been used in various scenarios: (i) screening a collection of 6000 binding sites for similarity to different queries; (ii) classifying protein families (serine endopeptidases, protein kinases) by binding site diversity; (iii) discriminating adenine-binding cavities from decoys. The fingerprint generation and comparison supports ultra-high throughput (ca. 1000 measures/s), does not require prior alignment of protein binding sites, and is able to detect local similarity among subpockets. It is thus particularly well suited to the functional annotation of novel genomic structures with low sequence identity to known X-ray templates. © 2010 American Chemical Society.
