本发明涉及式(I)的5-硫杂-ω-取代的苯基-前列腺素E衍生物、(其中,所有符号如说明书中定义)、其制备方法和含有它们作为活性成分的药物组合物。本发明式(I)化合物可以强力结合PGE2受体(特别是亚型EP4),所以预期它们被用于预防和/或治疗免疫学疾病(自身免疫疾病如肌萎缩性脊髓侧索硬化(ALS),多发性硬化症,斯耶格伦氏综合征,慢性关节风湿病和系统性红斑狼疮等,器官移植后排异等),哮喘,异常骨形成,神经元细胞死亡,肺衰竭,肝损伤,急性肝炎,肾炎,肾机能不全,高血压,心肌局部缺血,系统炎性响应综合征,灼伤疼痛,脓毒病,吸血综合征,巨噬细胞活化综合征,斯提耳氏病,川崎疾病,烧伤,系统性肉芽肿病,溃疡性结膜炎,节段性回肠炎,透析时血细胞心搏量,多发性器官衰竭和休克等。此外,据信EP4亚型受体涉及睡眠失调和血小板聚集,因此,预期本发明化合物用于预防和/或治疗这些疾病。
Description
发明领域
本发明涉及5-硫代-ω-取代的苯基-前列腺素E衍生物。
更具体地,本发明涉及式(I)的5-硫代-ω-取代的苯基-前列腺素E衍生物
(其中,所有符号在下面定义)。
背景技术
已知前列腺素E2(缩写PGE2)为花生四烯酸酯级联中的代谢物。已知PGE2具有细胞保护活性、子宫收缩活性、诱发疼痛作用、对消化蠕动的促进作用、唤醒作用、对胃酸分泌的抑制作用,降血压活性和利尿活性等。
在最近的研究中发现PGE2受体被分为几种亚型,它们彼此之间具有不同的物理作用。现在已知四种受体亚型,它们被称为EP1,EP2,EP3,EP4(Negishi M.等人,J.Lipid Mediators Cell Signaling,
12,379-391(1995))。
本发明人已经研究发现了可以特定结合每个受体的化合物,并且已经发现了可以强力结合EP4亚型受体的本发明化合物,进而完成了本发明。
据信EP4亚型受体涉及抑制TNF-α的产生和加速IL-10的产生。因此,预期可以强力结合EP4亚型受体的本发明化合物用于预防和/或治疗免疫学疾病(自身免疫疾病如肌萎缩性脊髓侧索硬化(ALS),多发性硬化症,斯耶格伦氏综合征,慢性关节风湿病和系统性红斑狼疮等,器官移植后排异等),哮喘,异常骨形成,神经元细胞死亡,肺衰竭,肝损伤,急性肝炎,肾炎,肾机能不全,高血压,心肌局部缺血,系统炎性响应综合征,灼伤疼痛,脓毒病,吸血综合征,巨噬细胞活化综合征,斯提耳氏病,川崎疾病,烧伤,系统性肉芽肿病,溃疡性结膜炎,节段性回肠炎,透析时血细胞心搏量,多器官衰竭和休克等。
此外,据信EP4亚型受体涉及睡眠失调和血小板聚集,因此,预期本发明化合物用于预防和/或治疗这些疾病。
本发明式(I)化合物弱结合其它亚型受体并且不表现其它作用,因此,预期这样的化合物是副作用小的药物。
另一方面,已知许多前列腺素在PG骨架的5位上的碳原子被硫原子替换并且在ω-链上的一个或多个碳原子被修饰。但是,对于这些前列腺素,没有具体公开在PG骨架的ω-链上具有未取代的或取代的苯基的前列腺素的文献。
例如,日本专利申请公开58-198466公开了具有抑制血小板聚集活性的下列5-硫杂-前列腺素衍生物。也就是说,其公开了式(A)5-硫杂-前列腺素
(其中R1是氢或C1-C10烷基,
R2是取代的或未取代的C1-C10烷基或取代的或未取代的C5~6环烷基,
R3或R4相同或不同,为氢或保护基)
当R1是氢时或其无毒盐,具有抑制血小板聚集活性和血管舒张活性,所以它们被用作治疗或预防血栓形成的药物和高血压药物。
在本专利说明书中,所示下列ω-环戊基-化合物是实施例3中的具体化合物
发明公开
本发明人已经研究发现可以特定结合EP4受体并且既不能结合其它EP亚型受体也不能结合其它前列腺素类受体的稳定化合物。
结果,他们已经发现通过在所述前列腺素的ω-链上引入取代的苯基修饰的5-硫代前列腺素能够满足上述目的,从而完成了本发明。
如下所述,本发明人已经发现其中PG骨架的α-链上的5位碳原子被硫原子替换并且被特定功能基取代的苯基被引入PG骨架的ω-链上的前列腺素化合物能够强力结合EP4,弱结合其它前列腺素类受体包括其它亚型受体,这样的化合物是稳定的,从而他们完成了本发明。

(I)用表达前列腺素受体亚型细胞的结合试验
