Many pharmaceutical companies have introduced a distinctive ‘hit-to-lead’ stage to drug discovery programmes. A common goal of hit-to-lead projects is to build confidence in a chemical series, reducing the risk...

Hit discovery and hit-to-lead approaches

Keseru GM and Makara GM
Drug Discovery Today

Hit discovery technologies range from traditional high-throughput screening to affinity selection of large libraries, fragment-based techniques and computer-aided de novo design, many of which have been extensively reviewed...

Improving the hit-to-lead process: data-driven assessment of drug-like and lead-like screening hits

Wunberg T, Hendrix M, Hillisch A, Lobell M, Meier H, Schmeck C, Wild H and Hinzen B
Drug Discovery Today

Drug-like and lead-like hits derived from HTS campaigns provide good starting points for lead optimization. However, too strong emphasis on potency as hit-selection parameter might hamper the success of such projects. A detailed absorption, distribution, metabolism, excretion and toxicology (ADME–Tox) profiling is needed...

Computational chemistry-driven decision making in lead generation

Schnecke V and Boström J
Drug Discovery Today

Novel starting points for drug discovery projects are generally found either by screening large collections of compounds or smaller more-focused libraries. Ideally, hundreds or even thousands of actives are initially found, and these need to be reduced to a handful of promising lead series...
