Heterocyclic molecules play a crucial role in health care and in pharmaceutical drug design. A large number of drugs used in Western medical practice are heterocyclic molecules. In this study, a set of norm indexes of the extended distance matrix are proposed. From these a stable and accurate structureproperty relationship model was developed for the prediction of the aryl hydrocarbon receptor binding affinity (pEC50) of dibenzofurans and the mutagenic potency (lnR) of aromatic and heteroaromatic amines. Our results indicate that the new model, based on these norm indexes, provides very satisfactory results, and that the average absolute differences for pEC50 prediction and lnR prediction were 0.403 and 0.702 with r2 (square correlation coefficient) values of 0.876 and 0.779, respectively. A comparison of these results with other methods demonstrates that our method, based only on the same mathematical model, performed better in terms of both accuracy and stability.



Keywords: Dibenzofuran   Aromatic and heteroaromatic amine   Aryl hydrocarbon receptor affinity   Mutagenic potency   Structure-property relationship   Norm index   Prediction
