| Quantitative Structure Activity Relationship |
(QSAR)
QSARs are based on a comparison of the structure or some physico-chemical property of a substance (“descriptor”) with a measured endpoint which may be another physico-chemical property or a biological effect. QSARs are normally taken to mean a mathematical relationship between a descriptor and a biological or physico-chemical endpoint. |
