We have discovered by high-throughput fragment-based docking several novel chemotypes of potent (single-digit nanomolar) and selective tyrosine kinase inhibitors [1-4]. Explicit solvent molecular dynamics has played an important role for the in silico validation of binding modes and the selection of compounds for testing in vitro. Definitive validation of the binding mode has been obtained by X-ray crystallography in our group [1,2]. The most advanced of our tyrosine kinase inhibitors are active on a subset of the NCI 60 cancer cell lines. Furthermore, some of our inhibitors have shown good pharmacokinetic properties in mice (including oral bioavailability) and are being currently selected for testing in tumor xenograft models. [1] K.

Alzheimer’s disease (AD) is a disruptive brain disorder characterized by a massive neuronal loss leading to a progressive decline of cognitive function. The cause of AD is poorly understood. Several hypotheses have been proposed over the years to explain the disease and to identify relevant drug targets. It has been shown that AD is always associated with the formation of plaques (amyloid hypothesis) as well as with the deposition of neurofibrillary tangles (tau hypothesis). There are few currently approved drugs, and these offer just a small benefit for a relatively short period of time. Nowadays, AD represents the largest unmet medical need in neurology. Our approach to drug discovery in AD has been based on a radical change of the classical ‘one-drug one-target’ paradigm into a multitarget drug discovery approach. In this seminar, two different series of molecules discovered following the multitarget strategy will be presented. The initial steps of our drug discovery strategy will be discussed, from structure-based drug design, carried out by means of computational tools, to chemical syntheses, and in vitro and in vivo characterization.
