Description
技术领域
本发明涉及一种以新型前列腺素衍生物、其制药学允许的盐或其水合物作为有效成分配合制得的睡眠诱导剂。
背景技术
由于前列腺素(以下称为PG)在微量下能发挥各种重要的生理作用,因此以医药应用为目的,对天然PG以及其大量衍生物的合成及生物活性进行了研究,并在很多文献中有报道。
其中,报道了PG的各种中枢作用,同时明确了它的脑内含量、生物合成、代谢通路以及其脑内局部存在或者随发育、年龄增长的变化等,并对PG引起的睡眠、觉醒等之间的关系等持有兴趣。其中,已经明确PGD2是调节开始睡眠和维持睡眠的液性因子,以PGD2诱导猴睡眠时,在脑波或行动上与自发性的自然睡眠没有区别(Proc.Natl.Acad.Sci.USA,第85卷,第4082~4086页,1988年),有希望成为新型具有睡眠诱导作用的化合物。但是,PGD2及PGD2衍生物因存在脑内的转移性以及稳定性等方面的问题,因而未被实用化。
另外,WO99/61419中公开了在α链上具有亚乙炔基的化合物,但是该化合物难以结晶,在制剂方面存在问题。
发明内容
本发明的目的为提供一种具有优良睡眠诱导作用的PG诱导剂。
本发明人等进行了深入的研究,结果发现下式(I)所表示的前列腺素衍生物具有优良的睡眠诱导作用,从而完成了本发明。
根据本发明的一种方案,本发明为式(I)所表示的前列腺素衍生物,其制药学允许的盐或其水合物。
(式中X表示α或β取代的卤原子,Y表示亚乙基、1,2-亚乙烯基或者亚乙炔基,R1表示C3-10的环烷基、被C1-4的直链或者支链状烷基取代的C3-10的环烷基、C4-13的环烷基烷基,R2为氢原子或者以CO2R3所表示的基团,R3表示氢原子、C1-4的直链或者支链状烷基或者C2-4的直链或者支链状链烯基,n表示1~4的整数,p表示0、1或者2。)
根据本发明的其它方案,本发明为上述前列腺素衍生物、其制药学允许的盐或其水合物,其中,式(I)中R1表示C3-10的环烷基或者C4-13的环烷基烷基。
根据本发明的其它方案,本发明为上述前列腺素衍生物、其制药学允许的盐或其水合物,其中,式(I)中X表示α或β取代的氯原子或者溴原子。
根据本发明的其它方案,本发明为上述前列腺素衍生物、其制药学允许的盐或其水合物,其中,式(I)中Y表示亚乙炔基。
根据本发明的其它方案,本发明为上述前列腺素衍生物、其制药学允许的盐或其水合物,其中,式(I)中R2为CO2R3基。
根据本发明的其它方案,本发明为上述前列腺素衍生物、其制药学允许的盐或其水合物,其中,式(I)中p=0。
根据本发明的其它方案,本发明为上述前列腺素衍生物、其制药学允许的盐或其水合物,其中,式(I)中n=1或2。
根据本发明的其它方案,本发明为一种药物组合物,其特征为,该药物组合物含有上述记载的前列腺素衍生物、其制药学允许的盐或其水合物。
具体实施方式
本发明中,作为卤原子,可以举出氟原子、氯原子、溴原子、或碘原子。
作为C3-10的环烷基,可以举出例如环丙基、环丁基、环戊基、环己基、环庚基、环辛基等。
作为被C1-4的直链或者支链状烷基取代的C3-10的环烷基,可以举出例如甲基环丙基、甲基环己基、乙基环己基等。
C4-13环烷基烷基是指以环烷基取代的烷基,优选为C3-10的环烷基-C1-3的烷基。可以举出例如环丙基甲基、环丁基甲基、环戊基甲基、环戊基乙基、环己基甲基、环己基乙基、环庚基甲基等。
作为C1-4的直链状或者支链状的烷基,可以举出,例如甲基、乙基、丙基、异丙基、丁基、异丁基、叔丁基等。
作为C2-4的直链或者支链状的链烯基,可以举出,例如烯丙基、丁烯基、2-甲基-2-丙烯基等。
作为制药学允许的盐,可以举出,例如与钠、钾等碱金属形成的盐,与钙、镁等碱土类金属形成的盐,与氨、甲基胺、二甲基胺、环戊基胺、苄胺、哌啶、单乙醇胺、二乙醇胺、单甲基单乙醇胺、缓血酸胺、赖氨酸、三(羟甲基)氨基甲烷等形成的盐。
n表示1~4的整数,从结晶性方面考虑优选n=1或2。
式(I)的化合物可以通过例如下列反应式所表示的方法进行制备。
反应式2
(反应式中,TBS为叔丁基二甲基甲硅烷基,Y’表示亚乙基或者1,2-亚乙烯基,R31表示C1-4烷基或者C2-4链烯基,p1表示1或2,Z表示卤原子,X、Y、R1、n与前述意义相同。)
下面对上述反应式进行说明。
(1)首先,通过左藤等的方法[有机化学杂志(J.Org.Chem),第53卷,第5590页(1988年)],使公知的式(II)化合物与0.8~2.0当量的式(III)或者式(III’)表示的化合物,在-78~30℃下,在惰性溶剂(例如,苯、甲苯、四氢呋喃、乙醚、二氯甲烷、正己烷等)中反应,得到立体异构的式(IV)的化合物。此处,若要得到Y为亚乙基或者1,2-亚乙烯基的化合物(即,Y为Y’的化合物),则使用式(III’)的化合物在-78~0℃下反应;若要得到Y为亚乙炔基的化合物,则使用式(III)的化合物在0~30℃下反应。
(2)使式(IV)的化合物与1~6当量的式(V)表示的化合物在有机溶剂(例如苯、甲苯、二甲苯、正己烷、正戊烷、丙酮等)中,于-78~100℃下发生反应,得到式(VI)的化合物。需要说明的是,上述反应根据需要使用0.05~2当量的自由基引发剂(例如,偶氮二异丁腈、偶氮二环己烷甲腈、过氧化苯甲酰、三乙基硼烷等),进一步根据需要使用1~5当量的自由基性还原剂(例如,氢化三丁基锡、氢化三苯基锡、氢化二丁基锡、氢化二苯基锡等)。另外,根据情况,使用0.05~2当量的碱(例如,三乙基胺、二异丙基胺、吡啶、二甲基苯胺等有机胺、聚乙烯基吡咯烷酮、二异丙基氨基甲基-聚苯乙烯、(哌啶子基甲基)聚苯乙烯等碱性树脂),在有机溶剂(例如苯、甲苯、二甲苯、正己烷、正戊烷、丙酮等)中,于-78~100℃下发生反应,也能够得到式(VI)的化合物。
(3)使式(VI)的化合物与0.5~5当量的氢化硼钾、氢化硼钠、氰基氢化硼钠、锂、三仲丁基氢硼化物、氢化二异丁基铝-BHT(2,6-二叔丁基-对甲酚)等还原剂在有机溶剂(例如,四氢呋喃、乙醚、乙醇、甲醇、甲苯等)中,于-78~40℃下发生反应,得到式(VII)及式(VII’)的化合物。上述式(VII)及式(VII’)的化合物可以利用柱色谱等常用的分离方法进行精制。
