An alphabetical directory of published research compounds, scientific aliases, development codes, and verified identifiers.
102 records
Filters read the fields stored in each record. A record with no assigned class, listed target, listed sequence, recorded terminal group or recorded ring closure is grouped under its own option; it may still have one that this Library has not yet verified. A small molecule, peptidomimetic or glycoprotein that declares no terminal group is listed as not a single peptide chain. Residue counts cover records with a listed sequence only. Filtered views can be shared by copying the page address.
