  • the present invention relates to heterocyclic compounds useful for the treatment of diseases mediated by EP2.
  • Endometriosis is a non-cancerous disease in which functional endometrial tissue is seeded outside the uterine cavity. Symptoms vary depending on the site of sowing, and include dysmenorrhea, sexual pain, infertility, dysuria, and pain during defecation. It is found in approximately 10% of women of reproductive age. Also, about 25-50% of infertile women have endometriosis. There are two main types of treatment: drug therapy and surgery. Prostaglandin synthesis inhibitors, oral contraceptives, progesterone preparations, gonadotropin-releasing hormone agonists, etc.
  • EP2 receptor is highly expressed in ectopic endometrial tissue, and proliferation and survival of human-derived endometrial epithelial cells and stromal cells are inhibited by selective EP2 receptor antagonists.
  • Non-patent Document 1 In endometriosis models using mice, treatment with ectopic endometrial tissue, inhibition of angiogenesis and nerve elongation, attenuation of hyperalgesia, etc., by using EP2 and EP4 receptor antagonists in combination The result which suggests an effect is also obtained (nonpatent literature 2).
  • Alzheimer's disease and mild cognitive impairment account for the majority of dementia, and the number of patients has increased significantly with the arrival of an aging society.
  • therapeutic drugs there are only symptom-improving drugs such as acetylcholinesterase inhibitors, and the development of drugs that stop or delay the progression of disease states or drugs that have a preventive effect is desired.

  • Non-Patent Document 3 As A ⁇ -lowering drugs, ⁇ -secretase inhibitors, ⁇ -secretase inhibitors, ⁇ -secretase function regulators, A ⁇ antibody drugs and the like have been developed, but there are still no drugs that have a sufficient effect. Therefore, development of a drug that lowers A ⁇ by a mechanism different from these is expected.
  • PGE2 mediates its effects through the G protein coupled receptors EP1, EP2, EP3 and EP4.
  • EP2 and EP4 receptors specifically couple with G proteins that activate adenylate cyclase and result in the production of cAMP. Both differential expression of EP receptors and their intracellular coupling pathways mediate diverse biological functions of PGE2 in different cell types (Non-Patent Document 3).
  • EP2 agonists have been reported to increase A ⁇ (Non-patent Document 4), and EP2 antagonists have been reported to decrease A ⁇ (Non-patent Document 5).
  • EP2 antagonists are Alzheimer's due to A ⁇ decrease. This suggests the possibility of becoming a disease treatment drug.

(発明の背景)
 子宮内膜症は、機能性の子宮内膜組織が子宮腔外に播種される非癌性疾患である。症状は播種の部位によって異なり、月経困難、性交疼痛、不妊、排尿障害、および排便時の痛みなどがある。生殖年齢の女性のおよそ10%にみられる。また不妊症女性の約25-50%に子宮内膜症が認められる。治療には大きく分けて薬物療法と外科療法の二つがある。薬物療法としてプロスタグランジン合成阻害薬、経口避妊薬、プロジェステロン製剤、ゴナドトロピン放出ホルモン作動薬などが用いられるが、副作用などの問題も多く、より安全で長期治療効果を有する新規薬剤の開発が求められている。EP2受容体は、異所性の子宮内膜組織に高発現しており、またヒト由来の子宮内膜上皮細胞や間質細胞の増殖や生存が選択的なEP2受容体の拮抗薬で阻害されることが報告されている(非特許文献1)。また、マウスを用いた子宮内膜症モデルにおいては、EP2およびEP4受容体拮抗薬の併用により、異所性子宮内膜組織の縮小、血管新生と神経伸張の抑制、痛覚過敏の減弱など、治療効果を示唆する結果も得られている(非特許文献2)。
 アルツハイマー病及び軽度認知障害は、認知症の大半を占めており、高齢化社会の到来と共に大幅に患者数が増加している。治療薬としては、アセチルコリンエステラーゼ阻害薬等の症状改善薬があるのみで、病態の進行を止める、若しくは遅らせる薬物、又は予防効果のある薬物の開発が望まれている。
 アルツハイマー病の発症原因としては、アミロイドβ(以下、単にAβということがある。)と呼ばれる約40個のアミノ酸からなるペプチドの蓄積により形成される老人斑や神経細胞死が考えられている。Aβ低下薬として、βセクレターゼ阻害薬、γセクレターゼ阻害薬、γセクレターゼ機能調節薬、Aβ抗体薬等の開発が多くなされているが、未だ十分な効果の認められる薬剤はない。従って、これらとは異なるメカニズムによってAβを低下させる薬剤の開発が期待されている。
 PGE2は、Gタンパク質共役型受容体EP1、EP2、EP3およびEP4によってその効果を媒介する。EP2およびEP4受容体は、アデニル酸シクラーゼを活性化しcAMPの産生をもたらすGタンパク質と特異的にカップリングする。EP受容体の差次的発現およびそれらの細胞内カップリング経路はいずれも、異なる細胞型のPGE2の多様な生物学的機能を媒介する(非特許文献3)。また、EP2作動薬はAβを増加させること(非特許文献4)、および、EP2拮抗薬はAβを低下させること(非特許文献5)がそれぞれ報告されており、EP2拮抗薬はAβ低下によるアルツハイマー病治療薬になりうる可能性が示唆される。
(Background of the Invention)
Endometriosis is a non-cancerous disease in which functional endometrial tissue is seeded outside the uterine cavity. Symptoms vary depending on the site of sowing, and include dysmenorrhea, sexual pain, infertility, dysuria, and pain during defecation. It is found in approximately 10% of women of reproductive age. Also, about 25-50% of infertile women have endometriosis. There are two main types of treatment: drug therapy and surgery. Prostaglandin synthesis inhibitors, oral contraceptives, progesterone preparations, gonadotropin-releasing hormone agonists, etc. are used as pharmacotherapy, but there are many problems such as side effects, and there is a need to develop new drugs that are safer and have long-term therapeutic effects. It has been. EP2 receptor is highly expressed in ectopic endometrial tissue, and proliferation and survival of human-derived endometrial epithelial cells and stromal cells are inhibited by selective EP2 receptor antagonists. Has been reported (Non-patent Document 1). In endometriosis models using mice, treatment with ectopic endometrial tissue, inhibition of angiogenesis and nerve elongation, attenuation of hyperalgesia, etc., by using EP2 and EP4 receptor antagonists in combination The result which suggests an effect is also obtained (nonpatent literature 2).
Alzheimer's disease and mild cognitive impairment account for the majority of dementia, and the number of patients has increased significantly with the arrival of an aging society. As therapeutic drugs, there are only symptom-improving drugs such as acetylcholinesterase inhibitors, and the development of drugs that stop or delay the progression of disease states or drugs that have a preventive effect is desired.
As a cause of the onset of Alzheimer's disease, senile plaques and neuronal cell death formed by accumulation of a peptide consisting of about 40 amino acids called amyloid β (hereinafter sometimes simply referred to as Aβ) are considered. As Aβ-lowering drugs, β-secretase inhibitors, γ-secretase inhibitors, γ-secretase function regulators, Aβ antibody drugs and the like have been developed, but there are still no drugs that have a sufficient effect. Therefore, development of a drug that lowers Aβ by a mechanism different from these is expected.
PGE2 mediates its effects through the G protein coupled receptors EP1, EP2, EP3 and EP4. EP2 and EP4 receptors specifically couple with G proteins that activate adenylate cyclase and result in the production of cAMP. Both differential expression of EP receptors and their intracellular coupling pathways mediate diverse biological functions of PGE2 in different cell types (Non-Patent Document 3). In addition, EP2 agonists have been reported to increase Aβ (Non-patent Document 4), and EP2 antagonists have been reported to decrease Aβ (Non-patent Document 5). EP2 antagonists are Alzheimer's due to Aβ decrease. This suggests the possibility of becoming a disease treatment drug.
