Title
(EN) AMINO QUINAZOLINE DERIVATIVES AS P2X3 INHIBITORS
(FR) DÉRIVÉS D'AMINO QUINAZOLINE SERVANT D'INHIBITEURS DE P2X3
Abstract
(EN) The present invention relates to compounds of formula I inhibiting P2X purinoceptor 3; particularly the invention relates to compounds that are amino quinazoline derivatives, methods of preparing such compounds, pharmaceutical compositions containing them and therapeutic use thereof. The compounds of the invention may be useful in the treatment of many disorders associated with P2X3 receptors mechanisms, such as respiratory diseases including cough, asthma, idiopathic pulmonary fibrosis (IPF) and chronic obstructive pulmonary disease (COPD).
(FR) L'invention concerne des composés de formule I inhibant un purinocepteur 3 de P2X ; en particulier, l'invention concerne des composés qui sont des dérivés d'amino quinazoline, des procédés de préparation de tels composés, des compositions pharmaceutiques les contenant et leur utilisation thérapeutique. Les composés selon l'invention peuvent être utiles dans le traitement de nombreux troubles associés à des mécanismes récepteurs de P2X3, tels que des maladies respiratoires y compris la toux, l'asthme, la fibrose pulmonaire idiopathique (IPF) et la bronchopneumopathie chronique obstructive (BPCO).
