Description

本発明は、オレキシン(OX)受容体拮抗作用を有する化合物及びその医薬上許容される塩、並びにそれらを有効成分として含有することを特徴とする医薬組成物、特に、睡眠障害、うつ病、不安障害、パニック障害、統合失調症、薬物依存症、アルツハイマー病、パーキンソン病、ハンチントン舞踏病、摂食障害、頭痛、片頭痛、疼痛、消化器疾患、てんかん、炎症、免疫関連疾患、内分泌関連疾患、高血圧等の疾患の治療又は予防薬に関する。   The present invention relates to a compound having orexin (OX) receptor antagonistic activity and a pharmaceutically acceptable salt thereof, and a pharmaceutical composition comprising them as active ingredients, particularly sleep disorders, depression, anxiety Disorder, panic disorder, schizophrenia, drug addiction, Alzheimer's disease, Parkinson's disease, Huntington's disease, eating disorder, headache, migraine, pain, digestive disorders, epilepsy, inflammation, immune related diseases, endocrine related diseases, The present invention relates to a therapeutic or preventive drug for diseases such as hypertension.

オレキシンは、視床下部外側野に特異的に発現するプレプロオレキシンからスプライシングされる神経ペプチドである。これまでに、33個のアミノ酸からなるOX−Aおよび28個のアミノ酸からなるOX−Bが同定されており、これらはいずれも睡眠・覚醒パターンの調節や摂食の調節に深く関与している。   Orexin is a neuropeptide spliced from preproorexin that is specifically expressed in the lateral hypothalamic area. So far, OX-A consisting of 33 amino acids and OX-B consisting of 28 amino acids have been identified, both of which are deeply involved in the regulation of sleep / wake patterns and the regulation of food intake. .

OX−AおよびOX−Bは、いずれもOX受容体に作用する。OX受容体は、これまでにOX1およびOX2受容体の2つのサブタイプがクローニングされており、いずれも主として脳内に発現する7回膜貫通Gタンパク質共役型受容体であることが知られている。OX1受容体は、Gタンパク質サブクラスのうちGqと特異的に共役しており、一方でOX2受容体はGqおよびGi/oに共役している(非特許文献1及び非特許文献2参照)。
OX受容体のサブタイプによって組織分布は異なっており、OX1受容体はノルアドレナリン作動性神経の起始核である青斑核、OX2受容体はヒスタミン神経の起始核である結節乳頭核に高密度に発現している(非特許文献3、非特許文献4及び非特許文献5参照)。セロトニン神経の起始核である縫線核や、ドパミン神経の起始核である腹側被蓋野にはOX1受容体とOX2受容体両方の発現がみられる(非特許文献3参照)。オレキシン神経は脳幹と視床下部のモノアミン神経系に投射し、それらの神経に対して興奮性の影響を与えており、さらにREM睡眠の制御に関わる脳幹のアセチルコリン神経にもOX2受容体の発現がみられ、これらの神経核の活性にも影響を及ぼしている(非特許文献3及び非特許文献4参照)。
Both OX-A and OX-B act on the OX receptor. The OX receptor has been cloned so far in two subtypes of OX1 and OX2 receptors, both of which are known to be 7-transmembrane G protein-coupled receptors that are mainly expressed in the brain. . The OX1 receptor is specifically conjugated to Gq in the G protein subclass, while the OX2 receptor is conjugated to Gq and Gi / o (see Non-Patent Document 1 and Non-Patent Document 2).
The tissue distribution varies depending on the subtype of the OX receptor. The OX1 receptor has a high density in the locus coeruleus, the origin of noradrenergic nerves, and the OX2 receptor in the nodule papillary nucleus, the origin of histamine neurons. (See Non-Patent Document 3, Non-Patent Document 4 and Non-Patent Document 5). Expression of both the OX1 receptor and the OX2 receptor is observed in the raphe nucleus which is the origin nucleus of the serotonin nerve and the ventral tegmental area which is the origin nucleus of the dopamine nerve (see Non-Patent Document 3). Orexin neurons project to the brain stem and the monoamine nervous system in the hypothalamus and have an excitatory effect on those nerves. Furthermore, the expression of OX2 receptors is also seen in the acetylcholine neurons of the brain stem involved in REM sleep control. It also affects the activity of these nerve nuclei (see Non-Patent Document 3 and Non-Patent Document 4).

近年、OX1およびOX2受容体と睡眠・覚醒調節との関連が注目されており、OX受容体拮抗作用を有する化合物の有用性が研究されている。OX−Aをラットの脳室内に投与すると、自発運動量の亢進(非特許文献6及び非特許文献7参照)、常同行動の亢進(非特許文献7参照)、覚醒時間の延長(非特許文献6参照)などが認められる。OX−Aの投与によるREM睡眠時間の短縮作用は、OX受容体拮抗物質の前処置により完全に拮抗される(非特許文献8参照)。さらに、経口投与が可能なOX1およびOX2受容体を同程度に拮抗する物質の投与により、運動量の減少、入眠潜時の短縮、non−REM睡眠量およびREM睡眠の増加が報告されている(非特許文献9および非特許文献10参照)。
OX受容体拮抗作用化合物として、特許文献1にはヘテロ芳香環誘導体が開示されているが、本願記載のヘテロ芳香環メチル環状アミン骨格を有する化合物についての開示はない。また、OX受容体拮抗作用化合物としては、例えば総説として非特許文献11に記載の種々の構造を有する化合物が知られているが、本願記載のヘテロ芳香環メチル環状アミン骨格を有する化合物についての開示はない。
In recent years, attention has been focused on the relationship between OX1 and OX2 receptors and sleep / wake regulation, and the usefulness of compounds having OX receptor antagonistic activity has been studied. When OX-A is administered into the cerebral ventricles of rats, the amount of spontaneous exercise is increased (see Non-Patent Document 6 and Non-Patent Document 7), the normal behavior is increased (see Non-Patent Document 7), and the awakening time is extended (Non-Patent Document). 6). The action of shortening REM sleep time by administration of OX-A is completely antagonized by pretreatment with an OX receptor antagonist (see Non-Patent Document 8). Furthermore, administration of substances that antagonize OX1 and OX2 receptors to the same extent that can be administered orally has been reported to reduce exercise, shorten sleep onset latency, increase non-REM sleep and REM sleep (non-) (See Patent Document 9 and Non-Patent Document 10).
As an OX receptor antagonistic compound, Patent Document 1 discloses a heteroaromatic ring derivative, but there is no disclosure of a compound having a heteroaromatic methyl cyclic amine skeleton described in the present application. In addition, as OX receptor antagonistic compounds, for example, compounds having various structures described in Non-Patent Document 11 are known as a review, but disclosure of compounds having a heteroaromatic methyl cyclic amine skeleton described in the present application is disclosed. There is no.

Test example (measurement of orexin antagonistic activity)
The antagonistic activity of test compounds against human orexin type 1 receptor (hOX1R) and orexin type 2 receptor (hOX2R) has been described in the literature (Toshikata Okumura et al., Biochemical and Biophysical Research Communications 280, 976-981, 2001). The method was modified. Chinese hamster ovary (CHO) cells forcibly expressing hOX1R and hOX2R were seeded in each well of a 96-well Black clear bottom plate (Nunc) at 20,000 cells, 0.1 mM MEM non-essential amino acids, 0. The cells were cultured in Ham's F-12 medium (Invitrogen) containing 5 mg / ml G418, 10% fetal calf serum for 16 hours under conditions of 37 ° C. and 5% CO 2. After removing the medium, assay buffer containing 25 μM Fluo-3AM ester (Dojin) (25 mM HEPES (Dojin), Hanks' balanced salt solution (Invitrogen), 0.1% bovine serum albumin, 2.5 mM probenecid, 100 μL of 200 μg / ml Amaranth (above Sigma-Aldrich), pH 7.4) was added and incubated for 60 minutes at 37 ° C., 5% CO 2. After removing the assay buffer containing Fluo-3AM ester, the test compound was dissolved in dimethyl sulfoxide to 10 mM, diluted with assay buffer, 150 μL was added, and the mixture was incubated for 30 minutes.
Peptide (Pyr-Pro-Leu-Pro-Asp-Ala-Cys-Arg-Gln-Lys-Thr-Ala-Ser-Cys-Arg-Leu-Tyr-Glu) substituted with 2 amino acids of human orexin-A which is a ligand -Leu-Leu-His-Gly-Ala-Gly-Asn-His-Ala-Ala-Gly-Ile-Leu-Thr-Leu-NH2; Each was diluted with an assay buffer so as to be 3 nM, and 50 μL of this ligand solution was added to initiate the reaction. For the reaction, the fluorescence value of each well was measured for 3 minutes every second using a Functional Drug Screening System (FDSS; manufactured by Hamamatsu Photonics), and the antagonistic activity was determined using the maximum fluorescence value as an index of intracellular Ca 2+ concentration. The antagonistic activity of the test compound was calculated by setting the fluorescence value of the well to which only the dilution buffer was added to 100% and the fluorescence value of the well to which the buffer solution containing no ligand and compound was added to 0%. The 50% inhibitory concentration (IC 50 value) was determined from the fluorescence value upon addition.
The IC 50 values of the compounds of the present invention are shown in Table 6.
