Published by U.S. EPA Office of Research and Development (ORD) | U.S. Environmental Protection Agency | Catalog Last Checked: April 21, 2026 at 08:00 PM | Dataset Last Updated: September 13, 2020
Table S1: Tox21 IDs mapped to NCGC IDs, PubChem IDs, and DSSTox IDs, and indicating NCATS, NTP and EPA partner library associations (date stamped February 24, 2020). Table S2: DSSTox TOX21SL list of substance IDs and structure formula, molecular weight, SMILES, InChI, and QSAR-ready SMILES (downloaded January 24, 2020). Table S3: DSSTox TOX21SL DTXSID overlaps with EPA CompTox Dashboard lists (downloaded January 24, 2020). Table S4: Predicted physicochemical properties and toxicities generated from OPERA, T.E.S.T, CORINA, and Derek Nexus models. Table S5: ToxPrint (V2.0_r711) fingerprint file for the TOX21SL chemical list. Table S6: Chemotype enrichment workflow results generated from binarized activity hit calls for ToxCast and Tox21 assay end points (aeids) obtained from EPA’s public ToxCast database, invitroDBv2. Table S7: Tox21 binarized assay hit call matrix for stereo and salt pairs, extracted from EPA’s public ToxCast database, invitroDBv3.
