Description
本發明係關於具有食慾激素(orexin)(OX)受體拮抗作用之化合物及其醫藥上容許之鹽,以及含有該等作為有效成分之睡眠障礙、憂鬱症、焦慮症(anxiety disorder)、恐慌症(panic disorder)、精神分裂症(Schizophrenia)、藥物上癮症、阿茲海默氏症、帕金森氏病、亨丁頓氏舞蹈症、飲食障礙、頭痛、偏頭痛、疼痛、消化器官疾病、癲癇、炎症、免疫相關疾病、內分泌相關疾病、高血壓等疾病之治療或預防藥。
食慾激素係自於下丘腦(Hypothalamus)外側區中特異表現之食慾激素前驅體(prepro-orexin)剪接(splicing)而成之神經肽。迄今為止,已鑑定出由33個胺基酸所成之OX-A及由28個胺基酸所成之OX-B,各均深切參與睡眠覺醒型態(sleep-wake patterns)之調節或飲食之調節。
OX-A及OX-B均作用於OX受體。OX受體迄
今已選殖出OX1及OX2受體之兩種亞型,已知均係主要在腦內表現之7次膜貫通G蛋白質共軛型受體(seven-transmembrane G protein-coupled receptor)。OX1受體與G蛋白質子類(subclass)中之Gq特異地共軛,另一方面,OX2受體則與Gq及Gi/o共軛(參考非專利文獻1及非專利文獻2)。
依據OX受體之亞型而定,組織分佈有所不同,OX1受體高度表現於去甲腎上腺素能神經元(noradrenergic neuron)之起始核(nucleus originis)的藍斑核(Locus Coeruleus),OX2受體則高度表現於組織胺神經元之起始核的結節乳頭核(tuberomammillary nucleus)(參考非專利文獻3、非專利文獻4及非專利文獻5)。於5-羥基色胺神經元(serotonin neuron)之起始核的線縫核(raphe nuclei)或多巴胺神經元之起始核的腹側被蓋區(ventral tegmental area)見到OX1受體與OX2受體二者之表現(參考非專利文獻3)。食慾激素神經元投射至腦幹與下丘腦之單胺神經系,對該等神經帶來興奮性之影響,進而於與REM睡眠控制有關之腦幹之乙醯膽鹼神經元亦見到OX2受體之表現,亦對該等神經核之活性帶來影響(參考非專利文獻3及非專利文獻4)。
近幾年來,OX1及OX2受體與睡眠覺醒調節
之關聯備受矚目,並已對具有OX受體拮抗作用之化合物的有用性進行研究。若將OX-A投予至大鼠腦室內,則見到自發運動量之亢進(參考非專利文獻6及非專利文獻7)
、定型行為(stereotyped behavior)之亢進(參考非專利文獻7)、覺醒時間之延長(參考非專利文獻6)等。因OX-A投予所致之REM睡眠時間之縮短作用藉由OX受體拮抗物質之前處置而完全受到拮抗(參考非專利文獻8)。再者,已報導藉由可經口投予之可同程度拮抗OX1及OX2受體之物質的投予,而減少運動量、縮短入睡潛期(sleep latency)、增加非-REM睡眠量及REM睡眠(參考非專利文獻9及非專利文獻10)。
至於OX受體拮抗作用化合物,於專利文獻1中雖揭示有雜芳香環衍生物,但關於本申請案所記載之具有雜芳香環甲基環狀胺骨架之化合物則無揭示。且,至於OX受體拮抗作用化合物,已知有例如作為概論之非專利文獻11中記載之具有各種構造之化合物,但關於本申請案所記載之具有雜芳香環甲基環狀胺骨架之化合物則無揭示。

試驗例(食慾激素拮抗活性之測定)
試驗化合物對人類食慾激素1型受體(hOX1R)、食慾激素2型受體(hOX2R)之拮抗活性係改變文獻(Toshikatsu Okumura等人Biochemical and Biophysical Research Communications 280,976-981,2001)所記載之方法而進行。將使hOX1R、hOX2R強制表現之中國倉鼠卵巢(CHO)細胞以於96孔之黑色透明底部盤(Nunc)之各孔中成為20,000個之方式進行接種,以包含0.1mM MEM非必須胺基酸、0.5mg/ml G418、10%胎牛血清之Ham’s F-12培養基(以上為Invitrogen),在37℃、5% CO2之條件下培養16小時。去除培養基後,添加100μL之含0.5μM Fluo-3AM酯(同仁)之分析用緩衝液(25mM HEPES(同仁)、Hanks’平衡鹽溶液(Invitrogen)、0.1%牛血清白蛋白、2.5mM二丙磺胺苯甲酸(probenecid)、200μg/ml Amaranth(以上為Sigma-Aldrich),pH7.4),以60分鐘、37℃、5% CO2培育。去除含Fluo-3AM酯之分析用緩衝液後,以二甲基亞碸將試驗化合物溶解成10mM,以分析用緩衝液稀釋後,添加150μL,培育30分鐘。
將配體的人類食慾激素-A之2胺基酸經取代之肽(Pyr-Pro-Leu-Pro-Asp-Ala-Cys-Arg-Gln-Lys-Thr-Ala-Ser-Cys-Arg-Leu-Tyr-Glu-Leu-Leu-His-Gly-Ala-Gly-Asn-His-Ala-Ala-Gly-Ile-Leu-Thr-Leu-NH2;Peptide研究所)以分析用緩衝液稀釋為相對於hOX1R為終濃度300pM、相對於hOX2R為終濃度3nM,添加該配體溶液50μL開始反應。反應係使用機能性藥物篩選系統(Functional Drug Screening System)(FDSS,濱松Photonic公司製)每1秒測定各孔之螢光值,測定3分鐘,將最大螢光值作為細胞內Ca2+濃度之指標,求得拮抗活性。試驗化合物之拮抗活性係將僅添加稀釋緩衝液之孔的螢光值作為100%,添加不含配體及化合物之緩衝液之孔的螢光值作為0%時予以算出,自添加各種濃度試驗化合物時之螢光值,求得50%抑制濃度(IC50值)。
