An objective of the invention is to provide novel compounds that present advantages compared to the compounds existing in the market for the treatment of Pain, especially neuropathic pain.The compounds are suitable as active principles should be used in preference to drugs, drugs to treat diseases or disorders, which, at least in part, be transmitted through K + channels KCNQ2 / 3.Unexpectedly, we found that the mercaptoquinolin - 2 - 3 - carboxamidas replaced the General formula of this application is suitable for the treatment of pain.Furthermore, it was found that the mercaptoquinolin - 2 - 3 - carboxamidas replaced the General formula of this application also excellent Affinity with the K + Channel KCNQ2 / 3 and, therefore, are suitable for treating Disorders or diseases that, at least in part, TR Ansmiten through K + channels KCNQ2 / 3.In this way, the mercaptoquinolin - 2 - 3 - carboxamidas replaced modulators acting as agonists or antagonists, i.e., The K + Channel KCNQ2 / 3, the procedure for producing them, to medicaments containing these Compounds, and the use of these compounds for the preparation of Medicines.Un objetivo de la invención consiste en disponer de nuevos compuestos que presentaran ventajas frente a los compuestos existentes en el mercado para el tratamiento del dolor, especialmente del dolor neuropático. Los compuestos debían ser adecuados especialmente como principios activos farmacológicos en medicamentos, de preferencia en medicamentos para tratar alteraciones o enfermedades, que, al menos en parte, se transmiten a través de los canales de K+ KCNQ2/3. Inesperadamente, se descubrió que las 2-mercaptoquinolin-3-carboxamidas sustituidas de la fórmula general de la presente solicitud son adecuadas para el tratamiento del dolor. Asimismo, se descubrió que las 2-mercaptoquinolin-3-carboxamidas sustituidas de la fórmula general de la presente solicitud también presentan una afinidad sobresaliente con el canal de K+ KCNQ2/3 y, por lo tanto, s
