In this paper, 13 4-N-nitrophenyl substituted amino-4H-1,2,4-triazole derivatives were synthesized and their aromatase inhibitory activities were measured. The results show that the substitution of the groups on benzyl group can further improve their bioactivity and the compound with Cl on the para position of benzyl has the highest bioactivity (IC50 = 9.02 nM). A QSAR model was constructed from the 13 compounds with genetic function approximation using DS 2.1 package. This model can explain 90.09% of the variance (R-Adj(2)), while it can predict 84.95% of the variance (R-cv(2)) with the confidence interval of 95%. (C) 2016 Elsevier Ltd. All rights reserved.
