In the drug discovery sequence, which activity identifies compounds with desired biological activity?

In drug discovery, the search for compounds that show the intended biological effect happens by screening large libraries against a target or biological assay to find hits. Those hits are then pursued to become lead compounds through validation and optimization, refining potency, selectivity, and drug-like properties. This screening-based lead discovery step is specifically where compounds with the desired biological activity are identified. Clinical trials come later, testing safety and efficacy in humans; preclinical toxicity testing looks at safety in animals before human use; and pharmacovigilance monitors safety after a drug is marketed.
