• There are a number of stages in the drug discovery process before human clinical trials begin.

The first, creative stage, consists in identifying interesting biological properties in an active ingredient, either synthetically prepared or of natural origin, and constituting a leader. This stage may involve high-throughput screening, using automated robots, of compounds from chemical substance collections (chemical libraries) or obtained by combinatorial chemistry (automated high-throughput syntheses). Knowledge of the therapeutic properties of raw materials of plant, fungal...
