Abstract
本发明提供了一种通过在哺乳动物中使用芳氧基丙醇胺来选择性拮抗5-HT1受体的方法,并且还提供了新的芳氧基丙醇胺。
Description
本发明提供具有对5-HT1选择性活性的丙醇胺类化合物,它在β-受体上有极微的作用。
已知有多种化合物对5-羟色胺受体有作用。然而,目前可以评价的只是5-羟色胺受体的若干公认的部位和亚型-参见Middlemiss,Annual Reports of Medicinal Chemistry,21,41-50(Academic Press,1986)和Glennon,J.Med.Chem.,30(1),1-12(1987)。例如,那些对于5-HT1受体选择性配位体的化合物对心血管系统、摄食行为、性功能、胃肠道功能和体温具有作用。
若干丙醇胺类例如心复宁和心得安表明对于5-HT1有拮抗作用,但由于它们的β-阻断活性,因而它们不是用于5-羟色胺受体的选择性试剂。
本发明提供一种选择性拮抗5-HT1受体的方法,该方法是通过给哺乳动物施用拮抗作用有效量的式Ⅰ化合物或其可药用的盐:
式中Ar是下列基团:
R1是在三个相连的碳原子中一个碳原子上被取代的任意甲基基团;
R2是氢、C1-C4烷基、三氟甲基、羟基、(C1-C4烷基)-O-、(C1-C4烷基)-S(O)p-或卤素;
R3是C3-C8环烷基或下式的双环烷基:
其中a和c各为1-5,b是0-5,并且(a+c)>2;
Z是直链或支链的C4-C10烷烃、烯烃或炔烃基团,可以被C1-C4烷基或苯基任意取代的(C4-C8环烷基)-G-,一个下式的双环烷基:
其中a和c各为1-5,b是0-5,并且(a+c)>2,
Z或可以是由苯基任意取代的C2-C10烷基,其中该苯基可以被如上述定义的R2任意取代;或是-(C1-C4亚烷基)-T-(C1-C4烷基),T是-O-,-S-,-SO-或-SO2-;
其中:
每个G各为一个键,或C1-C4亚烷基;
X是-H、-COY、-CN或C1-C4烷基;
Y是-OH、-O-(C1-C4烷基)、或-NH2;
……表示单键或双键;
Ra和Ra′各为氢或C1-C3烷基,或它们与其相连的碳原子一起形成一个C3-C8环烷基环;
P是0、1或2;
A是-O-、-S-、-NH-或-NCH3-和
m是0、1、2或3;
虽然已知诸如心复宁和心得安一类化合物能拮抗5-HT1A和5-HT1B受体,但它们用于此的浓度远超于阻断β-受体的浓度。因此,它们在有关5-HT1受体疾病的治疗性能和治疗状况方面的有效性受到了限制。
我们意想不到的发现,在这类化合物的胺官能团上用较长的和/或空间障碍较大的取代基来延展或取代这类化合物异丙胺取代基可以提供具有更多选择性的5-HT1受体拮抗药,也就是说,同拮抗5-HT1A受体相比较,它们与拮抗β-HT1受体的浓度比至少为1.0。因此,本发明所使用的化合物应能用于治疗各种有关5-HT1受体的病情,但并不随之而产生β-阻滞剂作用。因而可以观察到用于本发明的化合物所期望的作用包括治疗性机能障碍、抑郁症、食欲不振、焦虑症、精神分裂症、胃肠病、头痛和心血管疾病。
术语“C1-C4烷基”表示指甲基、乙基、丙基、异丙基、丁基、仲丁基、叔丁基和异丁基。术语“C4-C8环烷基”表示指环丁基、环戊基、环己基、环庚基和环辛基、在C5-C8环烷基环上的任意取代基可以取代于环的任何部位或可以取代于环上指定的位置,但不能取代于与氮原子相连的位置。
术语“直链或支链C4-C10烷基”包括直链烃形式或带有一个或多个支链部分形式的4-10个碳原子的烷基。同样,术语“直链或支链的C4-C10链烯基或炔基”是分别指含有双键或三键的类似的直链或支链烃基。“卤”表示指氟、氯、溴和碘。
术语“-(C1-C4亚烷基)-T-(C1-C4烷基)”表示指通过T官能度桥接的两个直链或支链的C1-C4烷基。术语“C1-C4亚烷基”表示指从C1-C4烷烃衍生的二价基。
作为R3和Z取代部分的双环烷基的定义包括4至17个碳原子的双环。这类双环烷基包括桥接和稠合的二环体系。代表Z取代基的实例于表1之中。
该被甲基任意取代的R1是指其中桥接于芳氧基和氨基官能度之间的三个碳原子被一个甲基任意取代的一种基团。即除了如图1所示的桥接-CH2CH(OH)CH2-之外,还包括如桥接基-CH(CH3)CH(OH)CH2-,-CH2C(OH)(CH3)CH2-,和-CH2CH(OH)CH(CH3)-。
应考虑到可能产生一种或多种立体异构体和/或对映体,这取决于R1、羟基和Z取代基。本发明并不限于任何特定的异构体,但是包括所有可能的单个异构体及其所有组合物。
用于本发明的可药用的加成盐包括由无机酸及有机酸衍生的盐,这类无机酸如盐酸、硝酸、磷酸、硫酸、氢溴酸、氢碘酸和亚磷酸等;这类有机酸如脂族的单或二羧酸、苯基取代的链烷酸,羟基链烷酸和羟基链烷双酸、芳香酸、脂族和芳族磺酸等。
用于本发明的优选化合物是那些心得安类型(Ar=1-萘基),尤其是心复宁类型(Ar=4-吲哚基)、氰基心复宁类型(Ar=2-氰-4-吲哚基)化合物,最优选的是环戊丁心胺类型(Ar=2-环戊苯基)化合物。R1基团最好是氢,并且Z取代基最好是支链烷基,特别是那些6-8个碳原子的烷基和环己基、环庚基、环辛基以及双环烷基衍生物。
用于本发明的化合物是5-羟色胺5-HT1受体拮抗药,并在β-受体上具体极微的作用。通过下列实验方法来评定本发明的化合物。
采用放射配位体受体的测定方法,即取体重为110-150g的Sprague-Dawley大雄鼠,切下头后立即取出脑。在屠宰场从小牛中迅速取出牛脑,在4℃下解剖出大脑皮层并在0.32M的蔗糖内进行均化。先在100xg离心10分钟再在17,000xg离心20分钟,沉降得到粗制的突触体部分。将该团粒悬浮于100倍体积的pH7.4的50mM tris-HCl缓冲液中,在37℃培养10分钟后,于50,000xg离心10分钟。重复上述方法,将最后得到的团粒悬浮于pH7.4的冰冷的50mM tris-HCl缓冲液。
按Wong等在J.Nueral Transm.,71,207(1988)所述方法,将3H-8-羟基-2-(二-正丙氨基)-1,2,3,4-四氢化萘(3H-80HDPAT)结合到5-羟色胺-1A受体。将从大鼠脑分离得到的大脑皮层膜(300μg蛋白质)在2ml培养基中于28℃培养30分钟,该培养基含有50mMpH7.4的tris-HCl缓冲液;10μM优降宁(pargyline);0.6mM抗坏血酸;5mM氯化钙;0.4nM 3H-80HDPAT和各种浓度的试验化合物。在减压条件下,通过玻璃纤维(GFB)滤纸,由过滤的样品来测定结合情况。该滤纸用5ml冰冷的缓冲液洗涤两次,并放于闪烁管内,用10ml PCS(Amersham/Searle)闪烁液洗脱,使用液体闪烁分光计测定放射性。3H-80HDPAT的特定结合是按照在没有螺环哌啶酮以及有10uM螺环哌啶酮存在时结合的放射性的不同情况来定义的。通过线性回归分析计算对3H-80HDPAT结合产生50%抑制作用(IC50)时所需的化合物浓度,5-HT1AIC50值列于表Ⅰ。
按Wong等在Biochemical Pharmacology,32(7),1287(1983)上所述方法,将3H-二氢心得舒(dihydroalprenolol)结合到β-肾上腺素能受体。将小牛脑的皮层膜(500ug蛋白质)放于2ml培养基中,于20℃培养20分钟,该培养基含有pH7.4的50mM tris-HCl缓冲液;2nM 3H-二氢心得舒和各种浓度的实验化合物。通过玻璃纤维(GFC)滤纸,由过滤的样品测定结合情况。在分离的样品中包含10uM L-心得安用于确定非特定的结合,其它条件如同用于3H-80HDPAT结合的叙述。βIC50的测定结果列于表Ⅰ。
在这些实验方法中用作评定本发明所说明的化合物列于表Ⅰ、Ⅱ和Ⅲ中。为用于比较,表中还提供了用于心得安如其中Z为异丙基的类似化合物的实验资料,并且也提供了它们的各种IC50比值。

从上述试验结果可以看到具有较长的和/或多个分支的氨基取代基的衍生物对5-HT1A受体有较大的亲和力,并能增强在β-受体上的选择性。例如,在环烷基系列中,当环由5增至6至7个碳原子时,该比值分别增至2.8、40.4和99。同样,那些具有多个分支,即在直链烃上含有多个甲基的芳环取代物比它们没有分支的同类化合物更有效,并且具有更大的选择性。值得注意的是:上述心得安的仲丁基或异丁基衍生物的选择性分别为28倍或几乎200倍于心得安的异丙基衍生物。
由于本发明的化合物对5-HT1A受体的选择性亲和力,因此它们用于治疗下列各种病症是有效的,这类病症如:肥胖症、食欲不振、抑郁症、高血压、衰老、丧失记忆力、性机能障碍、忧虑症、精神分裂症、胃肠道疾病、头痛和心血管疾病。用于治疗这些病情的典型日剂量含有药物有效量的式Ⅰ化合物中的一种化合物。用于本文的术语“药物有效量”表示该式Ⅰ化合物的用量是能对哺乳动物5-HT1A受体起作用的量。当然,该化合物给药时的具体剂量将由使用时的具体情况来决定,包括使用的特定化合物、给药途径、治疗的具体病情及类似的情况等。典型的日剂量含有约0.01mg/kg至约20mg/kg的式Ⅰ化合物。
该化合物能通过各种途径给药,包括口服、经直肠的、皮肤的、皮下的、静脉的、肌内的或鼻内的给药途径。该化合物能以药物配制剂的形式给药,该配制剂包括式Ⅰ化合物与一种或多种药物上可接受的赋形剂、稀释剂或载体相结合。这些配制剂在本技术领域是已知的,并能适于提供一种取决于给药途径和上述其它因素的单位剂量形式。
本发明还提供了上述类型的新化合物。该化合物及其可药用的盐以下列式Ⅰa来表示:
其中Za是(C6-C8环烷基)-G-、C6-C10烷基、苯基取代的C2-C10烷基、-(C1-C4亚烷基)-T-(C1-C4烷基)或下式基团:

其中X1是-H或-CN和G、T、a、b、c以及m如上述定义,其附带条件是:
(a)当Ar是1-萘基时,Za不可以是环己基、C6-C10烷基、苯基取代的C2-C10烷基、或-(C1-C4亚烷基)-T-(C1-C4烷基);和

本发明的另一方面包括制备本发明新化合物的方法。通常,该化合物优选按下列反应来制备:
按反应式Ⅰ,将羟基芳族中间体Ⅱ与表氯醇(Ⅲ)或其卤代同类物反应,得到环氧衍生物Ⅳ。该化合反应在本领域是非常确实的,并能通过若干方法进行,一般使用惰性溶剂和非反应的酸清除剂。然后将环氧化物Ⅳ与伯胺H2NZ反应得到本发明的化合物。再者,通常该反应在非反应的溶剂存在下,并在溶剂的蒸发温度以及直至该反应混合物的回流温度下进行。反应式Ⅰ是描绘那些其中R1是氢的预期化合物;用于本发明的其它化合物可以按类似方法,使用适当取代的卤代环氧化物衍生物Ⅲ来制备。任意用于本发明的可药用的盐也可以通过本领域技术人员熟知的常规方法来制备。
