ANALISIS QSAR-2D DE LOS DERIVADOS DE 1,4-DI-N-OXIDOS DE QUINOXALINA CON ACTIVIDAD CONTRA LA ENFERMEDAD DE CHAGAS

In the present work was performed a quantitative structure-activity relationship (QSAR) for a set of derivatives of 1,4-quinoxaline N-oxides with antichagasic activity based on reactivity descriptors from the frame conceptual DFT. QSAR models showed a good statistical quality and capacity internal prediction with R2 > 0.6 and Q2> 0.5 respectively. QSAR model suggest that antichagasic activity of the studied compounds depends largely from the reactive behavior of N-oxide group (N-O). Also, reactivity descriptors showed that the N-oxide group is a reactive site in theses derivatives with nucleophilic characteristics. The results QSAR shed light on the understanding of the mechanism of action and design of new drugs based on derivatives of 1,4-di-N-oxides quinoxaline.
