FAQs on the Toolbox
To increase the regulatory acceptance of (Q)SAR methods, the OECD has started the development of a QSAR Toolbox to make (Q)SAR technology readily accessible, transparent, and less demanding in terms of infrastructure costs.
The Toolbox is developed in phases. The first version emphasises technological proof-of-concept and was released in 2008. The second phase of the project to develop a more comprehensive Toolbox which fully implements the capabilities of the first version was launched in November 2008 and version 2.0 was released in October 2010. The third generation of the Toolbox, containing new features was launched in October 2012. The most recent version 3.2 was released in December 2013.
What does the Toolbox do?
The Toolbox is a software application intended to be used by 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.
The seminal features of the Toolbox are:
1. Identification of relevant structural characteristics and potential mechanism or mode of action of a target chemical.
2. Identification of other chemicals that have the same structural characteristics and/or mechanism or mode of action.
3. Use of existing experimental data to fill the data gap(s).
New features of the QSAR Toolbox version 3.0 are:
In version 3.1 of the QSAR Toolbox a number of these new features has been updated or extended and a new database for observed rat in vivo metabolism has been added. In addition, the QSAR Toolbox 3.1 contains improved interface and search functionalities (see release notes).
In version 3.2 of the QSAR Toolbox modifications have been made in several profilers and metabolic simulators and a number of databases have been updated. In addition, a number of general improvements have been, o.a. support of IUCLID 5.5, calculation of p-value for “read-across” predictions, improved interface and database performance (see release notes).
The toolbox also provides an approach to predict skin sensitization based on an new concept of adverse outcome pathways. This pathway approach is based on the concept that toxicity results from a chemical first reaching and then interacting with an initial key target (e.g. membrane, receptor) in the organism; this is defined as the primary molecular initiating event. Further to this primary interaction begins a series of events that can individually be documented and tested, resulting in an adverse outcome.

The Toolbox has benefitted from the contributions of numerous experts in governments, NGOs and the chemical industry. The software was developed by the Laboratory of Mathematical Chemistry.

Training materials for the Toolbox are also available below. This material can be freely used for training purposes.
Additional training material will be published as it is developed.
The OECD does not foresee to organise training sesions for the use of the Toolbox. Nevertheless training sessions are organised by other organisations which are referenced here:
Public Discussion Forum
A public discussion forum for users of the QSAR Toolbox is available. On this site users can:
• exchange experience with using the software (tips and tricks),
• seek guidance,
• exchange databases,
• exchange user defined profilers and QSARs, and
• make suggestions for improvements.
The discussion forum is accessible here: Forum
