Abstract
式(I)的化合物选择性地结合到类视色素RXR受体上,和其用作皮肤病和肿瘤病的抗增生剂的用途,其中R1-R7、R10、X和虚线键如说明书中给出的定义。
Description
本发明涉及新的视黄酸X受体(RXR)配位体。更具体地说,本发明涉及式(I)的化合物和式(I)化合物药学上可接受的羧酸盐:
其中虚线键是可有可无的;当有虚线键存在时,R1为低级烷基和R2为卤素,或R1和R2及与其相连的碳原子一起形成5-8元碳环或含有一个硫原子、氧原子或氮原子的5-8元杂环,其中当所说的环为芳族环时,虚线键是内消旋体系的一部分;或当虚线键不存在时,R1和R2连接在一起为亚甲基以形成顺式取代的环丙基环;R3为羟基或低级烷氧基;R4、R5、R6和R7分别为氢或低级烷基;X是(>CR8R9)n;和n是1、2或3;R8、R9分别为氢或低级烷基;R10为氢、烷基或烷氧基。
本文中使用的术语“低级”是指含有1-4个碳原子的基团。低级烷基可以是直链或支链的。优选为甲基和乙基。术语“卤素”包括氟、氯、溴和碘,其中优选为溴。由R1和R2及与其相连的碳原子一起形成的5-8元碳环的实例为苯、环戊烯、环己烯、环庚烯,其中优选为苯。由R1和R2及与其相连的碳原子一起形成的5-8元杂环的实例为噻吩、呋喃、二氢呋喃和吡啶,其中优选为噻吩。R4-R7优选为低级烷基,最优选为甲基。X优选为亚乙基。R10优选为氢。当可有可无的虚线键存在并成为芳族环内消旋体系的一部分时,这意味着该附加键如芳香性经典模型中所述为环上非定域键。
其中R1为低级烷基和R2为卤素,或R1和R2及与其相连的碳原子一起形成5-8元碳环或含有一个硫原子、氧原子或氮原子的5-8元杂环,其中当所说的环为芳族环时,相邻于R1和R2的碳原子之间的双键是内消旋体系的一部分;R3-R7、R10和X如通式I中的定义。
本发明的第二个方面优选包括通式Ib的化合物和其药学上可接受的羧酸盐:
其中R3-R7、R10和X如式I中的定义。
WO-A-9504036公开了RXR选择性的四氢化萘衍生物可以含脂族三烯酸侧链。GB-A-2122200公开了适用于治疗肿瘤和皮肤病的四氢化萘基二甲基辛基三烯酸衍生物。
其中R1至R7如式Ia中的定义。特别优选的是式Ia(1)的化合物,其中R4-R7都为甲基,和R1-R3如式Ia中的定义。最优选的是式Ia(1)的化合物,其中R4-R7都为甲基,R3为羟基和R1-R2如式Ia中的定义。
式Ib化合物中特别优选的化合物是下式的化合物:
其中R1至R7如式Ib中的定义。特别优选的是式Ib(1)的化合物,其中R4-R7都为甲基,R3如式Ib中的定义。
本发明还包括式Ia(1)和Ib(1)化合物的药学上可接受的羧酸盐。
本发明的化合物对于RXR族受体显示出高度的选择性。这些化合物可用作抗增生剂并且具有用于治疗皮肤病和肿瘤病适应症的用途。尤其是,本发明的化合物可抑制皮脂细胞(sebocytes)的增生,并因此可以用于治疗痤疮。
本发明的化合物还可以以其非活性剂量通过与视黄酸受体(RAR)的结合来提高其活性。这种RAR-选择性类视色素的实例是全反式视黄酸。因此,本发明的化合物与RAR-选择性类视色素结合使用能够使RAR-选择性类视色素以极低的剂量用于那些可使用RAR-选择性类视色素进行治疗的适应症。这类适应症中的一种就是人类的白血病。
本发明的化合物还可以与属于同一总族(superfamily)的其它核受体的配位体结合使用,其中与RXR如维生素D化合物或甲状腺激素生成杂二聚物并由此提高了它们的作用。
HL-60是对类视色素诱导的细胞分化特别敏感的人类骨髓性白血病细胞系(参见Breitman等人的Proc.Nat.Acad.Sci.USA 1989,86,7129-7133),因此可以用作测试细胞分化诱导活性的模型。HL-60分化的诱发是治疗人类白血病的标准模型。HL-60细胞的分化可以通过氮蓝四唑(NBT)的还原检测它们的氧化势来鉴定。将HL-60细胞保存在添加有105FCS、2mML-谷氨酸、1mM丙酮酸钠、1%非必需氨基酸、50U/ml青霉素和50微克/ml链霉素的RPMI 1640介质中。可以发现上述细胞中不含类菌质体。将30,000细胞/100微升的RPMI/FCS接种于平底的微滴培养井中。同时,加入10微升用弗氏完全佐剂稀释的类视色素溶液以使最终浓度达到10-11至10-6M之间(将在乙醇中的10-2M储备溶液保持在-20℃以下,且避光保存)。三天之后,用多流路吸移管除去介质和用100微升的NBT溶液置换除去的介质(1毫克/毫升在含有200nM佛波醇肉豆蔻酸盐乙酸盐的PBS中)。在37℃下,再培养1小时之后,除去NBT溶液并加入100微升10%SDS在0.01N HCl中的溶液。使用自动平板式读数器在540纳米下用光度学法确定NBT的还原量。计算出3个培养井的平均值。S.E.M为5%至10%。
图1-6表示全反式视黄酸单独使用及与本发明的化合物结合使用在诱导HL-60细胞分化方面所产生的效果。
在图1-6中,
化合物A是(2E,4E)-3-甲基-5-[3-(5,5,8,8-四甲基-5,6,7,8-四氢-萘-2-基)-苯硫-2-基]-戊-2,4-二烯酸(实施例2);
化合物B是(2E,4E)-3-甲基-5-[(1RS,2RS)-2-(5,5,8,8-四甲基-5,6,7,8-四氢-萘-2-基)-环丙基]-戊-2,4,-二烯酸(实施例6);
化合物C是(2E,4E)-3-甲基-5-[2-(5,5,8,8-四甲基-5,6,7,8-四氢-萘-2-基)-苯基]-戊-2,4,-二烯酸(实施例1);
化合物X是p-(5,5,8,8-四甲基-5,6,7,8-四氢-萘-2-萘甲酰氨基)-苯甲酸(参见,例如美国专利4,703,110)。
从所得的结果可以清楚地看到,本发明的化合物和全反式视黄酸结合使用所得的效果要优于这二种物质单独使用所得效果的加和。
因此,本发明的化合物可以用于治疗那些由类视色素作为中介体传递的病症。例如,本发明的化合物可以用于治疗或预防如痤疮或牛皮癣这样的皮肤病症。本发明的化合物相比于传统的RAR-选择性类视色素化合物如全反式视黄酸具有更低的毒性或致畸性。本发明的化合物可以与RAR-选择性类视色素一起施用,并由此可以减少这种类视色素的施用剂量,从而降低了由这种治疗产生副作用的危险。
其中A是甲酰基和B是三芳基磷鎓或二(低级烷氧基)氧膦基;或A是三芳基磷鎓或二(低级烷氧基)氧膦基和B是甲酰基;R是低级烷氧基;和R1、R2、R4、R5、R6、R7和R10如上述定义。
可以按照本身已知的方法如进行Wittig或Horner反应的方法来进行化合物II与化合物III的反应。
其中反应原料通式II和通式III化合物之一含有三芳基(优选三苯基)磷鎓基的反应(Wittig反应)可以在下述的条件下进行,即在酸结合剂例如强碱如丁基锂、氢化钠或二甲基亚砜的钠盐存在下,但主要是在被低级烷基任意取代的乙烯氧例如环氧丁烷的存在下,选择性地在溶剂中,例如,在醚溶剂如乙醚或四氢呋喃中或在芳烃溶剂如苯中,在室温至反应混合物的沸点这一温度范围内进行上述反应。磷鎓基团的阴离子可以是无机阴离子如氯离子或溴离子或硫酸氢根离子,或有机阴离子如甲苯磺酸根离子。
其中反应原料通式II和通式III化合物之一含有二烷氧基氧膦基的反应(Horner反应)可以在下述的条件下进行,即在碱存在下和优选在惰性有机溶剂存在下,例如,在苯、甲苯、二甲基甲酰胺、四氢呋喃、二噁烷或1,2-二甲氧基链烷烃中的氢化钠的存在下,或在链烷醇中的醇化钠如在甲醇中的甲醇钠存在下,在0℃至反应混合物沸点的温度范围内进行反应。在本发明优选的方面,通过其中A是甲酰基的通式II化合物与其中B是二(低级烷氧基)氧膦基的通式III化合物反应来制备通式I的化合物。
可以使用已知的方法如在室温至反应混合物的沸点这一温度范围内用碱,特别是用乙醇钠水溶液或氢氧化钾溶液处理上述得到的通式I的羧酸酯以使其水解。
可以用已知的方法将上述得到的通式I的羧酸以羧酸的形式或以盐如碱金属盐,特别是以Na或K盐的形式分离出来。
通式II的化合物是新化合物且也属于本发明所要保护的发明主题。通式II的化合物可以通过下述合成路线1、2和3来制备,其中R是低级烷基,Z是溴或碘,R1、R2和R4-R7及R10如前述定义:
合成路线3
通式II的化合物(其中有虚线键存在;R1为低级烷基和R2为氢;或R1和R2及与其相连的碳原子一起形成可以含有一个硫原子、氧原子或氮原子的5-8元芳香环或非芳香环)可以按照合成路线1来获得。在合成路线1中,首先,将通式(1)的化合物转化成它的锂或镁盐,经金属转移作用制成锌衍生物,然后,在过渡金属(优选钯)催化的反应中,与通式(2)化合物发生偶合从而得到通式(3)的化合物。例如可以使用金属氢化物如二异丁基氢化铝使通式(3)化合物中的羧酸酯基还原以生成通式(4)化合物,可以通过使用氧化剂如二氧化锰处理使通式(4)化合物中的羟甲基发生转化,从而得到通式II的化合物,其中A是甲酰基;R1是低级烷基和R2是氢;或R1和R2及与其相连的碳原子一起形成可以含有一个硫原子、氧原子或氮原子的5-8元芳香环或非芳香环。
其中R1是低级烷基和R2是氢的通式II化合物可以按照合成路线2来制备。按照合成路线2,使通式(5)的化合物与三(低级烷基)二氧磷基乙酸酯进行Wittig-Horner反应得到通式(6)的化合物。然后,经过如上所述的还原和氧化两步法,将通式(6)化合物中的酯基转化成甲酰基,从而分别得到通式(7)和(8)的化合物。可以通过卤化-脱去卤化氢的方法使通式(8)卤化,例如通过使用元素卤素如Br2处理,接着再用强碱如1,8-二氮双环[5.4.0]十一-7-烯(DBU)进行脱卤化氢反应,从而得到通式II的化合物,其中A是甲酰基,R1是低级烷基和R2是卤素。
其中不存在有虚线键,R1和R2连接在一起为亚甲基的通式II的化合物可以按照合成路线3来获得。在合成路线3中,在钯催化的反应中,用炔丙基醇处理通式(1)化合物得到炔属化合物(9)。使用例如三甲基甲硅烷基将炔丙基醇中的羟基可以保护起来。将化合物(9)中的三键还原制得化合物(10),再通过Simmons-Smith反应,将化合物(10)转化成化合物(11)。可以使用现有技术中已知的方法如使用氯铬酸吡啶或使用Swern-或Dess-Martin氧化法氧化化合物(11)以得到通式II的化合物,其中A是甲酰基,虚线键不存在,R1和R2连接在一起为亚甲基。
其中A是三芳基磷或二(低级烷氧基)氧膦基的通式II化合物可以由其中的A是甲酰的通式II化合物通过下述的方法制备,所述的方法是使用本身已知的方法,例如使用配合的金属氢化物如NaBH4将甲酰基还原成羟甲基,通过使用溴化剂或氯化剂如磷酰氯或三溴化磷进行处理以使溴或氯原子置换上述羟基,并使由此得到的溴化物或氯化物与三芳基膦或三(低级烷基)亚磷酸盐进行反应。所有这些反应都可用本身已知的方法来进行。
通式I的化合物和其盐可以以药物制剂的形式使用。
全身使用(systemic use)的制剂可以例如通过下述的方法来制备,即将通式I的化合物或其盐作为活性组分加入至这类制剂中常用的无毒性惰性固体或液体载体中。
制剂可以以经肠道、非肠道或局部使用的方式给药。例如,片剂、胶囊剂、糖衣药丸、糖浆、悬浮液、溶液和栓剂形式的制剂适用于经肠道给药。
输液或注射液形式的制剂适用于非肠道给药。
对于经肠道和非肠道给药而言,通式I化合物的成人给药量为约1-100毫克/天,优选5-30毫克/天。
对于局部给药而言,活性物质通常是以软膏、酊剂、乳膏、药膏、溶液、洗剂、喷雾剂、悬浮液等的形式使用。其中优选软膏和乳膏及溶液制剂。这些为局部给药而制成的制剂可以下述方法来制备,即将活性组分与适用于局部用药的且在这类制剂中常用的无毒性惰性固体或液体载体相混合。
对于局部给药而言,通常,活性组分适宜含量为约0.1-5%,优选0.3-2%的溶液以及约0.1-5%,优选0.3-2%的软膏或乳膏。
如果需要,还可将抗氧化剂如维生素E、N-甲基-γ-生育胺以及丁基化羟基苯甲醚或丁基化羟基甲苯与制剂相混合。
下面将通过实施例来进一步说明本发明。
