Normative ICH
What characteristics should a QSAR model have from a regulatory point of view? A case of the ICH regulation. As we saw in our previous post about what QSAR models are and how are they created, the REACH (chemical products) and ICH (drug) legislations not only accept, but also promote the use of alternative methods […]

Statistical techniques
What statistical techniques do QSAR models use? As we have seen in the previous entries, QSAR models allow predicting properties or activities of molecules, and are obtained from the analysis of molecular descriptors with statistical and/ or machine learning techniques. QSAR models can be used qualitatively to classify a substance, for example as a skin […]

Molecular descriptors
What are molecular descriptors? In order to generate QSAR models, it is necessary to codify in some way the characteristics of the molecules, in order to have the most detailed possible description of these. In other words, it is necessary to translate the molecular structures into numerical values that can be easily understood by computer […]

QSAR models
QSAR models, what are they and how are they created? The QSAR models, acronym for Quantitative Structure Activity Relationships, are based on one of the most used techniques in the field of chemoinformatics, as we saw in the previous entry. In this post we will help you to understand better how to obtain these models […]

Computational methods
What computational methods can we use to predict properties of substances? In the previous blog entry, we talked about chemoinformatics within the so-called alternative methods. However, what computational methods can we use to predict a toxicological or physicochemical property of a substance, according to current regulations? How do we decide which one to use? In […]

What is chemoinformatics?
What is chemoinformatics? The health and environmental effects of chemicals are increasingly relevant to the general public, regulatory agencies, academia, and industry. Thanks to the evolution of computational techniques, we have powerful tools for data management and complex mathematical calculations. In this context, chemoinformatics, one of the most relevant fields in the New Approach Methodologies, […]

Alternative methods
What are alternative methods to animal testing? According to the recent estimates, in the European Union alone, approximately ten million vertebrate animals are slaughtered for different experimental purposes (i.e., scientific, toxicological, regulatory, etc.). This is so because the efficacy of many chemical substances – e.g., pharmaceuticals, pesticides, food excipients, cosmetics, etc.- has traditionally been determined through the use […]
