The European Lead Factory: Results from a decade of collaborative, public-private, drug discovery programs.

The European Lead Factory (ELF) is a consortium of universities and small and medium-sized enterprises (SMEs) dedicated to drug discovery, and the pharmaceutical industry. This unprecedented consortium provides high-throughput screening, triage, and hit validation, including to non-consortium members. The ELF library was created through a novel compound-sharing model between nine pharmaceutical companies and expanded through library synthesis by chemistry-specialized SMEs.

The European Federation for Medicinal Chemistry and Chemical Biology (EFMC) Best Practice Initiative: Phenotypic Drug Discovery.

Phenotypic drug discovery has a long track record of delivering innovative drugs and has received renewed attention in the last few years. The promise of this approach, however, comes with several challenges that should be addressed to avoid wasting time and resources on drugs with undesired modes of action or, worse, false-positive hits. In this set of best practices, we go over the essential steps of phenotypic drug discovery and provide guidance on how to increase the chance of success in identifying validated and relevant chemical starting points for optimization: selecting the right assay, selecting the right compound screening library and developing appropriate hit validation assays.

The European Federation for Medicinal Chemistry (EFMC) Best Practice Initiative: Validating Chemical Probes.

As part of an initiative aimed to share best practices in Medicinal Chemistry, the European Federation for Medicinal Chemistry (EFMC) is preparing a series of webinars and slide sets focused on the early phase of drug discovery. This educational material is freely accessible through the EFMC. The main target audiences are students or early career scientists and we also believe it will be valuable for experienced practitioners.

Discovery of novel 7-azaindoles as PDK1 inhibitors.

A combined screening strategy using HTS together with focused kinase library and virtual screening led to the identification of diverse chemical series as PDK1 inhibitors. We focused our medicinal chemistry efforts on 7-azaindoles with low micromolar IC50s (e.g.
