About screening compounds
Screening compounds are drug-like small molecules supplied in collections for high throughput and phenotypic screening. They are usually chosen to follow guidelines such as Lipinski's rule of five, with filters that remove reactive groups and frequent hitters known as pan-assay interference compounds. Libraries include diverse collections, focused sets for target families such as kinases, GPCRs and ion channels, natural product-like compounds and covalent libraries.

Pharmaceutical companies, biotech start-ups and academic screening centres buy screening compounds by the thousand, often as DMSO solutions in 96 or 384 well plates, then reorder hits as dry powder for confirmation. Make-on-demand collections enumerate billions of virtual compounds that suppliers can synthesise within weeks.
Ask for purity by LC-MS (often at least 90 percent), identity confirmation, the plate format and concentration, the availability of the same batch for reorders, and the delivery time for make-on-demand compounds. Repeat purchases of hits should include NMR data. Check intellectual property terms, since compounds bought from catalogues are usually free to use, while some collections carry restrictions.
