Many proprietary QSAR models are readily available and easy to use, but often lack transparency and are like “black boxes” to end users. QSAR Model Reporting Format (QMRF) documents address this issue by providing a template for summarizing key information on QSAR models, where the information is structured according to the OECD (Q)SAR validation principles. In order to improve the availability and findability of QMRFs, we improved support for QMRFs in the QsarDB repository.
In today's world of scientific infrastructure, there is a lot of talk about the compliance of data with FAIR data principles. We decided to test the QsarDB data archives for compliance with FAIR data principles and we are pleased with the FAIRness of 75% for data and models in QsarDB.
The last quarter of 2020 brought a new community from Slovenia. Laboratory for Cheminformatics at National Institute of Chemistry (NIC). NIC has a long history for providing in silico tools for mechanistic and empirical modelling applicable for drug design, assessment of toxicity, and materials optimization.
Each model in QsarDB can be used for prediction if the user calculates or determines experimentally the descriptors in the model and enters them in the “QDB Predictor” application  or via the REST service . For some models, the prediction service also works directly from the structure. In this case, the QsarDB repository calculates the required molecular descriptors on the fly. Currently, QsarDB supports this functionality for a limited number of models, and they use open source software (Chemistry Development Kit, PaDEL-Descriptor and XlogP3) to calculate molecular descriptors.
In 2020, the QsarDB team celebrated Europe Day (May 9) in a modest but professional way. Namely, on that day, a new community was opened for the European Union Reference Laboratory for Alternatives to Animal Testing (EURL ECVAM), which is a part of the European Commission's Joint Research Center (JRC) in Ispra, Italy.
