Definition of the Subject

The fundamental hypothesis of the structure‐property models is that thestructural features of molecules determine the physical, chemical and biological properties of chemical compounds. The first studies that usestructure‐activity relationships to explain the biological properties of sets of compounds were published by Kopp [74], Crum-Brown and Frazer [18], Meyer [88], and Overton [97]. Modernstructure‐activity relationships (SAR) and quantitativestructure‐activity relationships (QSAR) models are based on theHansch model that predicts a biological property as a statistical correlation with steric, electronic, and hydrophobicindices [27,35,36,37]. The Hansch model shaped the general scene ofstructure‐activity correlations, and almost all subsequent SAR and QSAR models are variations that extend the Hansch model with novel classes ofdescriptors or with more powerful statistical models, such as partial least squares (PLS), artificial neural networks (ANN),...
