A topological-mathematical model has been developed based on Multilinear Regression Analysis in order to search new active molecules with mosquito repellent activity. The molecular characterization was performed using topological indexes and a 5-variable model was chosen for prediction of protection times (R2 = 0.8457 and Q2 = 0.7486). The model was validated by an internal leave-one-out-type cross-validation and a randomization test. The results confirmed the predictive power for the property under study. Finally, after carrying out a virtual screening, new compounds have been proposed with expected higher potency as mosquito repellents.
