To increase the regulatory acceptance of (Q)SAR methods, the OECD is developing a QSAR Toolbox to make (Q)SAR technology readily accessible, transparent, and less demanding in terms of infrastructure costs.
18 February – OECD launches QSAR Toolbox version 4.3. along with an updated website: https://qsartoolbox.org/.
New features of the QSAR Toolbox version 4.3 include:
For the complete list of new features please see the release notes.
Download the QSAR Toolbox and find more information at https://qsartoolbox.org/.
The Toolbox is a software application intended to the use of governments, chemical industry and other stakeholders in filling gaps in (eco)toxicity data needed for assessing the hazards of chemicals. The Toolbox incorporates information and tools from various sources into a logical workflow. Crucial to this workflow is grouping chemicals into chemical categories. Download our brochure (PDF).
The seminal features of the Toolbox are:
The toolbox also provides an approach to predict skin sensitisation based on the concept of Adverse Outcome Pathways. The Toolbox has been developed in several phases:
The purpose of this webinar was to demonstrate the new features of Version 4.0 of the QSAR Toolbox.
OECD: Brief overview of the purpose & history of the QSAR Toolbox. Basic concepts and organisation of the Toolbox including workflow, profilers, databases. Where to get support for Version 4.0 (tutorials, discussion forum).
ECHA: Practical examples for the use of the QSAR Toolbox v4.0, with focus on the new functionalities. Relevance of profilers and databases for a given endpoint. Automated and standardised workflows. Quantitative metabolic information. Improved reporting: new prediction report and exportable data matrix in excel format.
The functionalities of the new version were presented at the 2017 IT tools training during ECHA´s stakeholders´ day.
Latest version of the QSAR Toolbox (version 4.3) as well as instructions for installation and how to get started:
- Due to the size of the files, the downloads may take a few minutes.
The presentations of the QSAR Toolbox can be downloaded from the following table:
