Title (EN) 4-(BIPHEN-3-YL)-1H-PYRAZOLO[3,4-C]PYRIDAZINE DERIVATIVES OF FORMULA (I) AS GABA RECEPTOR MODULATORS FOR USE IN THE TREATMENT OF EPILEPSY AND PAIN
(FR) DÉRIVÉS 4-(BIPHÉNYL-3-YL)-1H-PYRAZOLO[3,4-C]PYRIDAZINE DE FORMULE (I) UTILISÉS COMME MODULATEURS DE RÉCEPTEUR GABA POUR LE TRAITEMENT DE L’ÉPILEPSIE ET DE LA DOULEUR
Abstract:
(EN) The present invention relates to pyrazolopyridazine derivatives. More particularly, it relates to 4-(biphenyl-3-yl)-1H-pyrazolo[3,4-c]pyridazine derivatives of formula (I), and pharmaceutically acceptable salts thereof, wherein X, R1, R2, R3, R4 and R5 are as defined in the description. The pyrazolopyridazine derivatives of the present invention modulate the activity of the GABAA receptor. They may useful in the treatment of a number of conditions, including pain and epilepsy.
(FR) La présente invention concerne des dérivés de la pyrazolo-pyridazine. L'invention concerne plus particulièrement des dérivés 4-(biphényl-3-yl)-1H-pyrazolo[3,4-c]pyridazine de formule (I), et leurs sels pharmaceutiquement acceptables, où X, R1, R2, R3, R4 et R5 sont tels que définis dans la description. Les dérivés de la pyrazolo-pyridazine selon l'invention modulent l'activité du récepteur GABAA. Ils sont utilisés pour le traitement d'un certain nombre d'affections, notamment la douleur et l'épilepsie.
