CA 2693552

[Solving Means] The present inventors have conducted extensive studies on an EP4 receptor agonist, and as a result, found that a novel pyridone compound characterized in that the 1-position in the pyridone ring is substituted with a group having an acidic group such as a carboxyl group and the 6-position is bonded with an aromatic ring group via lower alkyl, lower alkylene, ether, or thioether, has an excellent EP4 receptor agonistic action, thereby completing the present invention. Since the compound of the present invention has an excellent EP4 receptor agonistic action and a blood flow increasing action in the hindlimb of a rat, it is useful as a pharmaceutical, in particular, an agent for treating peripheral arterial occlusive disease.

L'invention concerne, selon des études approfondies et complètes, un agoniste du récepteur EP4, un nouveau composé de pyridone dans lequel la position 1 d'un cycle de pyridone est substituée par un groupe ayant un groupe acide tel qu'un groupe carboxyle et la position 6 du cycle de pyridone étant liée à un groupe de cycle aromatique par l'intermédiaire d'un groupe alkyle inférieur, d'un groupe alkylène inférieur, d'un éther ou d'un thioéther, ayant une bonne activité d'agoniste du récepteur EP4. Le composé a une bonne activité d'agoniste du récepteur EP4 et une bonne activité permettant d'augmenter l'écoulement sanguin fémoral chez un rat, et est par conséquent utile comme agent médicamenteux, en particulier comme agent thérapeutique pour les maladies artérielles périphériques.
