Toxicity Prediction via Hard-Soft Acid-Base Theory

“Application of the Hard and Soft, Acids and Bases (HSAB) Theory to Toxicant–Target Interactions” LoPachin, R. M.; Gavin, T; DeCaprio, A.; Barber, D. S. Chem. Res. Toxicol. 201225, 239-251. DOI: 10.1021/tx2003257

I considered posting about the Carreira group‘s work on enantioselective amination of allylic alcohols, because I think it is an awesome example of direct functionalization of hydroxylated substrates–an issue that will be of increasing importance in terms of biomass utilization. However I chose instead to stray into the less familiar territory of the bioactivity of organic molecules. I am semi-familiar with quantitative structure activity relationship (QSAR) modeling, wherein a database of known molecules and their bioactivity is used to predict the bioactivity of a molecule about which there is no bioactivity data. However, relying solely on computers leaves me wanting a more intuitive grasp on which molecules are expected to be toxic/non-toxic and why. That’s why I got excited about the recent perspective article about using the familiar Hard-Soft Acid-Base theory to predict toxicant-target interactions.
