Abstract
本发明涉及一种用于缓解或预防便秘,也用于净化胃肠道的新导泻组合物。该组合物包含导泻诱导有效量的卤代生物活性脂,该脂包含下列部分结构(I)。
Description
技术领域
本发明涉及一种新导泻组合物,可用于缓解或预防便秘,也可以用于净化胃肠道。
背景技术
便秘分为功能性便秘如无力性便秘,痉挛便秘和直肠便秘,肠道疾病造成的器官便秘以及因手术后粘连造成的狭窄等,以及药物-诱导的便秘等类别。
传统上用于缓解这些便秘症状的泻药包括,例如,1)大肠-刺激剂蒽醌泻药,2)小肠-刺激剂蓖麻油,3)增量泻药如羧甲基纤维素,4)盐类泻药,如硫酸镁以及5)糖类泻药,如糖醇。然而,这些泻药依靠刺激肠道产生的强制激活起作用,以致它们带来像排便之类的腹泻和诱导各种副作用,例如,当泻空时引起胃痛。
通过促进肠道蠕动的胃肠道净化一向用于内窥镜检查、诊断或手术程序的准备工作,例如用于结肠镜检查术、钡餐X-射线和静脉肾盂造影的准备,以及急诊程序如胃肠道冲洗排毒。
电解质净化方法一般应用于清洁肠道,包括通过摄入大量仅含电解质的等渗水来诱导腹泻。然而,由于大量水的摄入,故该方法不能用于具有肾脏障碍、心脏病或高血压的患者。最近,由硫酸钠、氯化钾、氯化钠碳酸氢钠和结合水的聚乙二醇(PEG)组成的PEG/电解质净化组合物,由Davis等人于1980年报道,被使用得最多。然而,此种PEG/电解质净化组合物一般都要求摄入多达2~4L的大量溶液,而且它很难喝下去,因为它太咸,具有油腻和粘糊口感。由于这些原因,要花很长时间,吃相当大的苦头才能喝下所要求的体积。因此,目前要求开发一种药,它易于摄入,以较小体积就能发挥所想要的作用。
同时,生物活性脂类,例如,花生四烯酸代谢物、血小板活化因子、溶血磷脂酸、脂溶性维生素、内毒素等都在深层次上涉及调节细胞的分化和繁殖、biophylaxis和神经功能。由花生四烯酸衍生的生物活性脂类包括,例如,前列腺素和血栓烷。
前列腺素(以下称PG)是一类有机羧酸的成员,存在于人类或其他哺乳类的组织和器官中,并表现出宽范围生理活性。天然存在的PG(原生(primary)PG)一般具有通式(A)所示前列腺烷酸的主链:
(α链)
(ω链)
另一方面,原生PG的某些合成类似物具有改性的主链。原生PG,根据其五元环部分的结构划分为PGA、PGB、PGC、PGD、PGE、PGF、PGG、PGH、PGI和PGJ,并按照不饱和键的数目和在碳链部分的位置进一步分为以下3种类型:
下标1:13,14-不饱和的-15-OH
下标2:5,6-和13,14-二不饱和的-15-OH
下标3:5,6-,13,14-和17,18-三不饱和的-15-OH。
另外,PGF按照在9-部位的羟基基团构型,分为α型(羟基基团具有α-构型)和β型(羟基基团具有β-构型)。
PG已知具有各种各样药理学和生物学活性。例如,PG诱导血管舒张、炎症和血小板凝集;刺激子宫和肠道,但是它们却只能起到很差的肠积液(enterpooling)效应。由于因肠道收缩引起胃痛之类的副作用,PGE或PGF不能用作泻药。

附图简述
图1代表化合物5的HPLC谱图。该化合物被拆分成了表异构物(化合物6和7)。
发明详述
PG化合物作为生物活性脂之一在本文中所使用的命名规则基于上面通式(A)中所代表的前列腺酸的编号系统。
通式(A)显示C-20碳原子的基本主链,但本发明不限于具有相同碳原子数目的那些。在通式(A)中,构成PG化合物基本主链的碳原子的编号从羧酸(编号1)开始,而在α-链中则从2~7朝向五元环编号,环内的那些是8~12,而ω-链中的那些是13~20。当α-链中的碳原子数目减少时,则从位置2开始依次去掉该编号;当α-链中碳原子数增加时,化合物被称作在位置2具有相应取代基,以取代羧酸基因(C-1),的取代化合物。类似地,当ω-链中碳原子数减少时,从位置20开始依次去掉该编号;而当ω-链中碳原子数增加时,超过20的碳原子数被命名为取代基。该化合物的立体化学与上面通式(A)的化合物一样,除非另外指出。
一般而言,术语PGD、PGE和PGF每一个代表一种在部位9和/或11具有羟基基团的PG化合物,但在本文中,这些术语也包括在部位9和/或11具有除羟基基团外的取代基的那些。此类化合物被称作9-脱羟基-9-取代-PG化合物或11-脱羟基-11-取代-PG化合物。当PG化合物具有氢以替代羟基基团时就简单地称作9-或11-脱羟基化合物。
如上所述,前列腺素化合物的命名基于前列腺酸主链。然而,在该化合物具有与前列腺素类似的部分结构时,可以使用“PG”的缩写。于是,一种PG化合物,若其α-链延长了2个碳原子,就是说,在α-链中具有9个碳原子则命名为2-脱羧-2-(2-羧乙基)-PG化合物。类似地,在α-链中具有11个碳原子的PG化合物被命名为2-脱羧-2-(4-羧丁基)-PG化合物。进而,ω-链延长了两个碳原子的PG化合物,即在ω-链中具有10个碳原子,则命名为20-乙基-PG化合物。然而,这些化合物也可按照IUPAC命名法来命名。
本发明使用的PG化合物可包括任何PG衍生物或类似物,只要它在15部位具有羟基基团并在16部位具有至少一个卤素原子。据此,例如,在13~14部位具有双键的PG类型1化合物,在13~14和5~6部位具有两个双键的PG类型2化合物,在5~6、13~14和17~18部位具有3个双键的PG类型3化合物;13,14-二氢-PG化合物,其中在13~14部位的双键是单键者。
本发明使用的化合物的典型例子包括PG类型1、PG类型2、PG类型3、13,14-二氢-PG类型1、13,14-二氢-PG类型2、13,14-二氢-PG类型3及其衍生物或类似物。
类似物(包括取代的衍生物)或衍生物包括:其在α-链端的羧基基团被酯化的PG化合物;其α-链延长的化合物;其生理学可接受盐;在2~3部位具有双键或在部位5~6具有三键的化合物、在部位3、5、6、16、17、18、19和/或20具有取代基的化合物;以及在部位9和/或11具有低级烷基或羟基(低级)烷基基团以替代羟基基团的化合物。
按照本发明,在部位3、17、18和/或19的优选取代基包括1~4个碳原子的烷基,尤其是甲基和乙基。在部位16的优选取代基包括低级烷基如甲基和乙基,羟基、卤素原子如氯和氟以及芳氧基如三氟甲基苯氧基。按照本发明,至少一个在部位16的取代基由卤素原子取代。在部位17的优选取代基包括低级烷基如甲基和乙基、羟基、卤素原子如氯和氟,以及芳氧基如三氟甲基苯氧基。在部位20的优选取代基包括饱和或不饱和低级烷基如C1~4烷基、低级烷氧基如C1~4烷氧基以及低级烷氧基烷基如C1~4烷氧基-C1~4烷基。在部位5的优选取代基包括卤素原子如氯和氟。在部位6的优选取代基包括形成羰基基团的氧代基团。在部位9和/或11具有羟基、低级烷基或羟基(低级)烷基取代基的PG的立体化学可以是α、β或其混合物。
另外,上面的衍生物和类似物可以是,在其链比原生PG短的ω-链末端具有烷氧基、环烷基、环烷氧基、苯氧基或苯基基团的化合物。
本发明尤其优选使用的化合物由通式(III)代表:
其中L和M是氢、羟基、卤素、低级烷基、羟基(低级)烷基或氧代,其中L和M中至少之一是非氢的基团,并且五元环可具有至少一个双键;
