SAR and QSAR in Understanding the Chemical Nature of Endocrine Active Chemicals

Importance of SAR and QSAR in Understanding the Chemical Nature of Endocrine Active Chemicals 

Most of the knowledge that we have regarding the interaction of chemicals with the endocrine system comes from in vitro receptor binding data. These receptor interaction data form the basis for many of the structure-activity relationships that have been derived for potential endocrine disruptors. It is important to note that potency measured in in vitro studies may or may not be relevant to the in vivo situation. The relative binding affinity (RBA) and potency of binding vary significantly within a given class of substances. For example, Branham et al. [11] reported
