Definitions
- the present invention relates to a morphinan derivative or a pharmacologically acceptable acid addition salt thereof having excellent selectivity and antagonism for an orexin receptor, and a pharmaceutical use thereof.
- Orexin is an intracerebral neuropeptide produced in the lateral hypothalamic area, orexin A (hereinafter referred to as “OX-A”; 33 amino acid residues) and orexin B, which are enzymatically excised from the precursor preproorexin. (Hereinafter referred to as “OX-B”; 28 amino acid residues) are known.
- Orexin receptors include two types of G protein-coupled receptors, orexin 1 (hereinafter “OX1”) receptor and orexin 2 (hereinafter “OX2”) receptor. It is thought that the receptor is conjugated to Gq and the OX2 receptor is conjugated to Gq and Gi / o.
- OX-A activates the OX1 receptor and OX2 receptor with similar potency, whereas OX-B relatively activates the OX2 receptor (Non-patent Document 1). Physiological effects that are presumed to involve orexin are thought to be expressed through one or both of the OX1 receptor and the OX2 receptor.
- Orexin is known to play an important role in controlling feeding behavior and maintaining sleep / wakefulness that are essential for life, and is involved in the regulation of energy metabolism and glucose metabolism. For example, it has been observed that when mice or rats are fasted, the expression level of orexin increases, and when orexin is administered to the mice or rats in the brain, food intake increases. Orexin is a factor that causes eating by changing arousal levels and emotions according to the metabolic state of humans, and is thought to be involved in many pathophysiology such as obesity, eating disorders, and sleep disorders. It has been reported (Non-Patent Documents 2 and 3).
- Narcolepsy is a sleep disorder characterized by excessive daytime sleepiness, emotional weakness, sleep onset hallucinations, and sleep paralysis, and is also a disease in which attention deficit hyperactivity disorder (ADHD) -like symptoms are observed. It has been reported that it develops due to dysfunction of the nervous system (Non-patent Document 4).
- ADHD attention deficit hyperactivity disorder
- Non-patent Document 5 It has also been reported that an orexin receptor antagonist exhibits an antidepressant-like action in a mouse depression model (Non-patent Document 5).
- compounds that have an inhibitory action on OX1 receptor are addiction and abuse of drugs such as ethanol, nicotine, cocaine, cannabinoids and morphine, and overeating.
- drugs such as ethanol, nicotine, cocaine, cannabinoids and morphine, and overeating.
- drugs such as ethanol, nicotine, cocaine, cannabinoids and morphine
- Non-patent Document 6 a compound having an inhibitory action on the OX1 receptor can be a therapeutic agent candidate for panic disorders such as panic attacks and anticipatory anxiety thereof.
- orexin receptors are depressed; anxiety; addictive; obsessive-compulsive disorder; affective neurosis; depressive neurosis; anxiety neuropathy; mood modulation disorder; behavioral disorder; mood disorder; Dysfunction; schizophrenia; manic depression; delirium; dementia; severe mental retardation and movement disorders (such as Huntington's disease and Tourette syndrome); eating disorders (such as anorexia, increased appetite, epidemic and obesity) Etc.); addiction (eg, overeating / vomiting); cardiovascular disease; diabetes; appetite / taste disorder; vomiting; vomiting; nausea; asthma; cancer; Parkinson's disease; Basic adenoma; Prolactinoma; Hyperprolactinemia; Pituitary tumor / adenomas; Hypothalamic disease; Inflammatory bowel disease; Gastric dyskinesia; Gastric ulcer; Frehlic syndrome; Adreno hypophysis Pituitary disease; Adrenohypophysis hypofunction; Adrenohypophysis hyperfunction; Hypothalamic hypogon
- Non-Patent Document 1 discloses various compounds having OX receptor antagonistic activity.
- Non-Patent Document 8 discloses a specific morphinan structure that exhibits potent opioid ⁇ receptor agonistic activity (Patent Document 5), ORL1 receptor antagonistic action (Patent Document 6), and drug dependence therapeutic action (Patent Document 7). It has been disclosed that compounds having a OX1 receptor antagonistic activity.

チャイニーズハムスター卵巣由来細胞株であるCHO細胞にNFAT-ルシフェラーゼ遺伝子及びヒトOX1R遺伝子又はヒトOX2R遺伝子をそれぞれ恒常的に発現させた細胞株(CHOOX1R,CHOOX2R)を樹立した。それらの細胞を96ウェルマルチプレート中に10,000個/ウェルで播種し、5%FBS(サーモサイエンティフィック社製)添加DMEM培地(シグマアルドリッチ社製)で、37℃、5%CO2の条件下に、48時間培養した。培地を除去後、5μM Fura-2AM(ケイマンケミカル社製)を含むアッセイ用緩衝液(20mM HEPES(シグマアルドリッチ社製)、Hanks’ balanced salt solution(ギブコ社製)、0.1%BSA(シグマアルドリッチ社製)、2.5mMプロベネシド酸(和光純薬工業社製)、pH7.4)を100μL添加し、37℃、5%CO2の条件下で、60分間インキュベートした。Fura-2AMを含む緩衝液を除去した後、アッセイ用緩衝液75μLを添加した。そこに種々の濃度の被験化合物及びOX-A(ペプチド研究所製)を含むアッセイ用緩衝液25μLを添加し、反応を開始した。反応による細胞内カルシウムイオン濃度の変化は、FDSS7000(浜松ホトニクス社製)を用いて、340nm及び380nmの二波長励起による蛍光波長510nMの蛍光強度比を測定することにより評価した。OX-Aを300pM添加したときの最大蛍光強度比を100%、アッセイ用緩衝液のみを添加したときの最大蛍光強度比を0%とし、OX-Aの300pM存在下で種々の濃度の被験化合物を添加した際の最大蛍光強度比の値から、拮抗活性の濃度反応曲線を作成し、非線形回帰曲線より50%阻害濃度(IC50)を算出した。なお、被験化合物は10mMとなるようにDMSOに溶解(DMSOの最終濃度は1%)した後、最終濃度が3.0×10-10M~1.0×10-5M(公比3)となり、かつOX-Aが300pMになるようにアッセイ用緩衝液で希釈した。実験は、4ウェルで行い、その平均を各々の値として、1例のIC50を算出した。なお、例数が2例以上の場合は、その平均値をIC50とした。
