PYRIDAZINE COMPOUNDS, THEIR PREPARATION, AND THEIR THERAPEUTIC USES

The present invention relates to a compound of formula (I) wherein n is 1 or 2, R1 is halogen, (C1-C4)alkyl, halo(C1-C4)alkyl, (C1-C4)alkoxy, halo(C1-C4)alkoxy, ethynyl, propargyl, or (C3-C6)cycloalkyl, or two R1 form a cyclopentane ring fused to the phenol; R2 and R3 represent H, cyano, ethynyl, propargyl, (C1-C4)alkyl, hydroxy(C1-C4)alkyl or a halo(C1-C4)alkyl, or R2 and R3 form together with the atoms connecting them a (C5-C6)carbocyclic ring fused to the pyridazine ring; R4 and R5 form together with N to which they are attached an optionally substituted 3-7 membered monocyclic heterocycloalkyl ring, 8-11 membered bicyclic heterocycloalkyl ring or 7-12 membered bicyclic heterocyclic spiro ring. The present invention also relates to a medicament and a pharmaceutical composition comprising said compound of formula (I), as well as their therapeutic uses, in particular as inhibitor of NOD-like receptor protein 3 inflammasome for treating for example Parkinson's disease or frontotemporal Dementia.
