QSAR TOOLBOX

Software for grouping chemicals into categories and filling gaps in (eco)toxicity data needed for assessing the hazard of chemicals.

QSAR Toolbox is freeware developed with the scientific and financial assistance of OECD and the European Union.  The software tool facilitates the application of the category approach for identifying and filling fate and (eco)toxicity data gaps for chemicals hazard assessment.

 

 

QSAR Toolbox facilitates chemicals hazard assessment by:

 

  • Use of predefined categories, refinement of existing or development of new categories.

 

  • Identification of analogue chemicals (or category) based on user selected interaction mechanisms or molecular features.  The later can be oriented to identify analogues of a studied chemical or to categorize chemicals according to their chemical, environmental or health properties.

 

  • Categorization of chemicals accounting for their metabolism: rate of disappearance, formation of stable metabolites, formation of high reactive intermediates, deactivation pathways, etc.

 

  • Extracting of all available experimental or pre-calculated data from local and remote (web) based databases accompanied with information about their reliability: experimental error, analytical or computational method used, replicates, etc.

 

  • Filling gaps of missing information within the category by read across, trend analysis and (Q)SAR models. (Q)SAR's predictions are accompanied with information concerning their mechanistic background, training chemicals, statistics, applicability domain and validity.

 

New features of QSAR Toolbox 4.1:

 

  • Save-load documents
  • Load lists of chemicals with CAS or SMILES, only
  • Access to data and knowledge via Web Services
  • Defining target endpoint which will specify the knowledge and data for subsequent category building
  • Profile statistics with metabolism is available
  • New protein binding alerts for Skin sensitization according to GHS classification
  • Providing Alert (Functionality) performance accounting for metabolism
  • Update of existing profilers and metabolic simulators
  • REACH Skin sensitisation database (normalized) with curated LLNA (EC3) data
  • Import to IUCLID 6 via web services
  • Model domain can be saved as a custom profile or SAR
  • Endpoint vs. Endpoint - the relationship between categorical endpoints is visualized graphically
  • Data matrix - possibility to report the data matrix

New features of QSAR Toolbox 4.0:

 

The new Toolbox 4.0 is not a continuation of the Toolbox 3.4 codebase. It is a new system, designed from the bottom up and rewritten using new underlying technologies and database management sub-system. This in turn means a completely different deployment experience.
