Feature Updates 

• Advanced Search > Molecular Formula Search has a new option, Formula Contains that has been made the default selection 
• Reply column has been added to the Comments page 
• Updated the Hazard and HTPP data and assay descriptions, respectively, to accordions to be more widely accessible 
• In the downloaded Batch Search file after MS-Ready SMILES are selected, MS-Ready mass and MS-Ready formulae are now included 

Data (Updated) 

• The hazard database is updated to ToxValDB v9.5, visualized on the Hazard and Executive Summary tabs. ToxValDB v9.5 represents a major restructuring compared to previous versions, please see the EPA CCTE Clowder repository for more detail. 
  • Executive Summary tab restructure due to updated ToxValDB 
    • Reproductive and Developmental Toxicology endpoints are now displayed together 
    • Subacute, endocrine system, and occupational exposure endpoints are no longer displayed 
  • Hazard subtab 
    • The scope of ToxValDB has been modified to focus curation efforts on human health-relevant toxicity information. Visit the ECOTOX Knowledgebase (ECOTOX, www.epa.gov/ecotox) to access ecological toxicity data from over 54,000 publications, including effects and endpoints measured and detailed metadata from each toxicity test on test compound, test organism, study design, test conditions, and statistical analysis.  
    • Revised classification schemes were developed for effect type supercategory, risk assessment class, study type, study duration class, and quality control. 
    • A new classification was added to indicate whether records were experimentally-derived, as opposed to cases where the numeric for the effect level is based on an analogue or surrogate chemical. 
    • Improvements to source document accessibility have been made via added columns of subsource URL and stored source record (links to associated documents in the EPA CCTE Clowder repository) 
  • Genotoxicity subtab

  • Added HTTr and HTPP data and visualizations - data from EPA's High Throughput Transcriptomics (HTTr) and High Throughput Phenotypic Profiling (HTPP) have been added in separate “HTTr: Summary” and “HTTP: Summary” tabs, under the “Bioactivity” main tab. Data can be visualized in plots, searched, and downloaded.
  • Extended ToxVal download available in batch search - A new “Enhanced Data Sheet ->ToxVal Details” in the batch search allows the user to download the ToxVal data values. The ability to populate a Yes/No column for ToxVal data from the batch search “Metadata->Include ToxVal Data Availability” is still available.
  • Extended chemical property download available in batch search - A new “Enhanced Data Sheet -> Chemical Properties Details” in the batch search allows the user to download the experimental and predicted chemical property values altogether.
  • Updated demographics exposure predictions under “Exposure -> Exposure Predictions” to include multiple predictors (e.g., Systematic Empirical Evaluation of Models (SEEM), Stochastic Human Exposure and Dose Simulation (SHEDS), USETox), and new generic predictions data table for predicted production volume, presence/absence on the Stockholm Convention list, and probability of type of exposure.
  • Updated “More” column in the Hazard data table to include more complete metadata.
  • Updated ADME>IVIVE data table to include multiple species (human and rat), multiple models (1 compartment, 3 compartment steady state, and physiologically based toxicokinetic (PBTK)), and multiple percentiles (50% and 95%)
  • Streamlined the About dropdown menu and the About page
• Data
  • Data update
    • DSSTOX (prod_dsstox_202202), including ~300,000 new chemicals, plus updated MS-Ready and QSAR-Ready structures, and ACD Names
    • invitroDBv3.5 (prod_internal_invitrodb_v3_5), including updates to the ToxCast bioactivity data
    • ChemExpoDB (prod_factotum_202009), visible from the Exposure tabs
  • New data
    • HTTr (ro_httr_20220120) and HTPP (res_htpp_u2os_apcra) added in new sub-tabs under the Bioactivity tab
    • Please note, this initial release of the HTPP visualization includes the dataset published in Nyffeler et al. 2020 (PMID: 31899216). Data on additional chemicals, including additional PFAS chemicals, will be made available in future releases.
  • Note, new chemicals have been added as this release has incorporated an update to the DSSTOX database. The current update includes MS-Ready and QSAR-Ready structures and ACD Names. Due to limited resources, an update to the chemical predictions (TEST, OPERA, Percepta/ACD Labs, EPISuite) have not been included at this time. Please stay tuned for a future release containing these data.
  • Note, analytical QC data have not yet been incorporated. There are columns in the HTTr and HTPP data tables as placeholders. Please stay tuned for a future release containing these data, specifically for PFAS compounds in the near future.
• Resolved Issues
  • Executive summary links work properly
  • Chemical list SDF download works
  • Chemicals with only DTXCID values are now visible
  • Broken image in chemical tile view is fixed
  • ToxPrint fingerprints (ChemoTyper) are now downloadable in standard CSV format
  • Link in downloadable data from the batch search using ToxVal Data Availability now works
  • Updated NIH NCATS Tox21 analytical QC link
• Known Issues
  • ACD/Labs values for water solubility are listed incorrectly
  • Chemical structure images in the predicted TEST reports are missing
  • TEST, OPERA, Percepta/ACD Labs, EPISuite chemical predictions are not yet available for the newly added chemicals
  • Production volume data are outdated. Until the updated data are available, please refer to: https://www.epa.gov/chemical-data-reporting/access-cdr-data
  • Analytical QC data have not yet been incorporated in the bioactivity data tables
