本発明は、後記式(I)で示されるピペラジニルピリジン誘導体の、セロトニン受容体サブタイプ1A(5−HT1A)作動作用とセロトニン受容体サブタイプ3(5−HT3)拮抗作用を併有する薬剤としての利用、殊に、該ピペラジニルピリジン誘導体を有効成分として含有する過敏性腸症候群(Irritable Bowel Syndrome;以下、「IBS」という)等の処置剤に関する。 The present invention combines a serotonin receptor subtype 1A (5-HT 1A ) agonistic action and a serotonin receptor subtype 3 (5-HT 3 ) antagonistic action of a piperazinylpyridine derivative represented by the following formula (I). In particular, the present invention relates to a therapeutic agent such as irritable bowel syndrome (hereinafter referred to as “IBS”) containing the piperazinylpyridine derivative as an active ingredient.
IBSは下痢や便秘等の便通異常や腹痛を主症状とする疾患で、腸管の器質的病変を認めない機能的疾患である。IBSは、腸管運動異常、内臓知覚過敏及び心理・社会的因子が相互に関連し合って成立している。 IBS is a disease mainly having stool abnormalities such as diarrhea and constipation and abdominal pain, and is a functional disease in which no organic lesions of the intestine are recognized. IBS is formed by intestinal motility abnormalities, visceral hypersensitivity, and psychological and social factors interrelated.
腸管には種々のセロトニン受容体サブタイプが存在するが、このうち、5−HT3は腸管収縮、腸液分泌、蠕動運動、内容物輸送等に関与している。したがって、IBSによる下痢症状が5−HT3拮抗薬によって改善されることがあり、実際に米国において、5−HT3拮抗薬であるアロセトロン(alosetron)がIBS治療薬として承認されている。 Although the intestinal There are various serotonin receptor subtypes, of which, 5-HT 3 intestinal contraction, intestinal fluid secretion, peristalsis, are involved in the contents such as transportation. Therefore, diarrhea symptoms caused by IBS may be ameliorated by 5-HT 3 antagonists. In fact, 5-HT 3 antagonist alosetron has been approved as an IBS therapeutic agent in the United States.
特許文献1及び特許文献2には、オンダンセトロン(ondansetron)、アロセトロン(alosetron)、トロピセトロン(tropisetron)あるいはグラニセトロン(granisetron)などの種々の5−HT3拮抗薬がIBS治療剤として有用であることが記載されている。 In Patent Document 1 and Patent Document 2, various 5-HT 3 antagonists such as ondansetron, allosetron, tropisetron, or granisetron are useful as IBS therapeutic agents. It is described.
非特許文献1には、5−HT3受容体に対して選択的に親和性を有するピペラジニルピラジン誘導体が記載されているが、非特許文献1に記載されているピペラジニルピリジン誘導体の5−HT3受容体に対する作用は作動作用である。 Non-Patent Document 1 describes a piperazinyl pyrazine derivative having selective affinity for the 5-HT 3 receptor, but the piperazinyl pyridine derivative described in Non-Patent Document 1 The action on the 5-HT 3 receptor is an agonistic action.
一方、IBSには心理的・社会的因子も関与していることから、抗不安薬がIBSの治療において何らかの有用性を示す可能性もあり、この可能性を拠り所にして、ベンゾジアゼピン系の抗不安薬がIBSの治療の目的にて用いられる場合もある。最近、より副作用の少ない非ベンゾジアゼピン系化合物を含むセロトニン作動性の抗不安薬が開発され、それらの化合物のIBS治療における有用性が期待されている。 On the other hand, since psychological and social factors are involved in IBS, anxiolytic drugs may show some usefulness in the treatment of IBS. Based on this possibility, benzodiazepine anxiolytic In some cases, the drug is used for the purpose of treating IBS. Recently, serotonergic anxiolytic drugs including non-benzodiazepine compounds with fewer side effects have been developed, and their usefulness in the treatment of IBS is expected.
我が国においては、5−HT1A作動薬であるタンドスピロン(tandospirone)がストレス性消化性潰瘍等を適応症として上市されている。しかしながら、当該化合物はIBSの適応症を有していない。 In Japan, the 5-HT 1A agonist tandospirone is marketed for the indication of stress peptic ulcer and the like. However, the compound has no indication for IBS.
非特許文献2には、5−HT1A受容体に対して選択的に親和性を有するピリミジノン誘導体が開示されている。この文献においては、5−HT1A受容体への選択性がα1受容体に対する選択性との比較において検討されている。 Non-Patent Document 2 discloses a pyrimidinone derivative having selective affinity for the 5-HT 1A receptor. In this document, the selectivity for the 5-HT 1A receptor is examined in comparison with the selectivity for the α 1 receptor.
特許文献3及び4には、5−HT1A受容体に対する親和性を有するアリールピペラジン誘導体が開示されている。これらの文献においては、アリールピペラジンの5−HT1A受容体に対する作用に基づく精神的作用が検討されている。 Patent Documents 3 and 4 disclose aryl piperazine derivatives having affinity for the 5-HT 1A receptor. In these documents, a mental action based on the action of arylpiperazines on 5-HT 1A receptors is examined.
上記のように、これまで、種々の5−HT3拮抗薬又は5−HT1A作動薬が提案されているが、それらの化合物が5−HT1A作動作用及び5−HT3拮抗作用の両作用を併せ持つかどうかについては検討されていない。また、これまでに開発又は上市されている5−HT3拮抗薬又は5−HT1A作動薬はいずれも、その作用が一方向性であるため、複数の成因を有するIBSに対して十分な治療効果を発揮するまでには至っていない。 As described above, various 5-HT 3 antagonists or 5-HT 1A agonists have been proposed so far, and these compounds have both 5-HT 1A agonistic action and 5-HT 3 antagonistic action. Whether or not to have both is not considered. In addition, since 5-HT 3 antagonists or 5-HT 1A agonists that have been developed or marketed so far are unidirectional in their action, sufficient treatment for IBS having multiple causes is possible. It has not yet reached its effect.
非特許文献3には、5−HT1A及び5−HT3の両受容体に対して親和性を有するベンズイミダゾール−アリルピペラジン誘導体が開示されている。しかしながら、この文献には、当該誘導体の神経系に対する作用について記載されているのみで、5−HT3拮抗作用及び5−HT1A作動作用の両作用をIBSに対して作用させることについては記載されていない。
本発明の主たる目的は、5−HT1A作動作用と5−HT3拮抗作用を併有する薬剤を提供することである。 The main object of the present invention is to provide a drug having both 5-HT 1A agonistic action and 5-HT 3 antagonistic action.
本発明の別の目的は、また、当該拮抗剤を有効成分とするIBS等の処置剤を提供することである。 Another object of the present invention is to provide a therapeutic agent such as IBS containing the antagonist as an active ingredient.
