Quantitative Structure Activity Relationship.


QSAR - quantitative structure-activity relationship - is a method to correlate the chemical structure of a molecule with its chemical, physical, pharmaceutical, or biological etc. effect.

Using QSAR developed methods are used particularly in chemo computer science, drug discovery and to assess the biological activity of chemical compounds, but also for toxicological and ecotoxicological assessments of individual chemicals within the meaning of risk management (for example in the REACh Regulation of Euopean Union).

One of the first applications of quantitative structure-activity relationship was the predicting of boiling points and pKa values of organic compounds.

Mathematical models - usually implemented in the form of computer programs - are referred to as QSAR models, which use calculations based on the chemical structure to predict the physical-chemical properties, the biological properties and statements about the fate of substances in the environment.

The following directory lists online available information and sources for quantitative structure-activity relationships.
