Hit to lead (H2L) also known as lead generation is a stage in early drug discovery where small molecule hits from a high throughput screen (HTS) are evaluated and undergo limited optimization to identify promising lead compounds.
Hit identification is the process of identifying and delivering a compound with confirmed activity against a biological target; hit finding typically occurs after target identification and validation, and before hit-to-lead and lead optimization studies. The two main approaches to hit ID are target-based and phenotypic.
The Hit confirmation phase is follows: Exclusion of hits with potential reactivity, assay interference or aggregation. Re-testing: compounds that were found active against the selected target are re-tested using the same assay conditions used during the HTS. Dose response curve generation: an IC50 or EC50 value is then generated.
8. Jan. 2021 · Modern drug discovery that is focused on delivering novel, small-molecule therapeutics to treat disease, via either target-based or phenotypic approaches, typically identifies bioactive starting points (“hits”) through the screening of a greater library of molecules.

The hit validation process typically consists of a suite of assays to confirm the hit activity and on-target activity. This process aims to eliminate false positives, confirm the activity with the expected target, and to establish the initial ranking of compounds by activity.
9. Sept. 2013 · Virtual screening, traditional high-throughput screening, and fragment-based screening are now established as three important hit identification paradigms in drug discovery. The goal of these screens is often to discover initial hit compounds for further medicinal chemistry optimization.
