Abstract
本发明公开了由结构式(I)代表的化合物,其中变量如文中定义。本发明还公开了上述化合物在抑制被称为辅助性T细胞2表达的化学引诱剂受体同源分子(“CRTH2”)、G蛋白结合受体方面的应用,从而治疗炎性疾病。
Description
发明背景
PGD2(前列腺素D2)属于来源于花生四烯酸的前列腺素类。它是由活性肥大细胞产生的主要类前列腺素,并且涉及过敏性疾病的发病机理,例如哮喘、鼻炎和特应性皮炎(参见Lewis等人,期刊《免疫学》1982年第129期1627页;Hardy等人,英文期刊《医药学》1984年第311期209页;Murray等人,英文期刊《医药学》1986年第315期第800页;Barry等人,期刊《药理学》1988年第94期第773页)。前列腺素D2是DP受体的配体,最初被认为通过此受体激发了所有的生物作用。利用DP缺陷鼠,已经证实了DP受体在过敏性哮喘中的作用(参见Matsuoka等人,《科学》2000年第287期第2013页)。最近,又鉴别出,前列腺素D2是另一种被称为“Th2上表达的化学引诱剂受体同源分子”或者简单地称为“CRTH2”、G蛋白结合受体的配体(参见,Tanaka等人,期刊《免疫学》2000年第164期第2277页;和美国专利申请US2002/0022218)。CRTh2是在Th2类型的嗜碱细胞、嗜曙红细胞和免疫辅助细胞上表达的。经证实,Th2细胞涉及过敏性响应的作用过程(参见Wills-Karp,《免疫学年刊》1999年第17期第255页)。经证实,前列腺素D2通过CRTH2受体诱导了Th2细胞与嗜曙红细胞的趋化性,说明了CRTh2在过敏性疾病中发挥了促炎性作用(参见,Hirai等人,期刊《医药学快报》2001年第193期第255页)。还经证实的有,在特应性皮炎受试体中随着病情的加重,表达CRTh2的循环T细胞的数量相应地增加(参见Cosmi等人,欧洲期刊《免疫学》2000年第30期第2972页;Iwazaki等人,期刊《皮肤病学研究》2002年第119期第609页)。由此,通过其受体DP和CRTh2,前列腺素D2涉及炎症的各个方面。因此,CRTH2和DP的拮抗剂被认为可用于治疗前列腺素D2介导的疾病。不幸的是,现在几乎没有任何公知的CRTH2抑制剂。结果是,没有研究出新型CRTH2抑制剂,临床医生就无法开发出这方面的成果。
发明概述
经发现,某些1,2,3,4-四氢-喹啉-4-基-胺是CRTH2的有效抑制剂。例如,在Ki小于1.0μM时一些化合物有效地抑制了前列腺素D2与稳定表达CRTH2的HEK-293细胞的结合。基于此发现,本发明公开了CRTH2抑制剂、含有此抑制剂的药用组合物和抑制受试体CRTH2活性的治疗方法。
本发明的一个具体实施方式是由结构式(I)代表的化合物:
其中环A是任意取代的芳香环;
R是-X1-R1;
RX是-X2-R4,和R3是任意取代的环脂肪族基团,任意取代的芳香族基团或者非芳香族杂环基团;或者将-N-RX-R3整体考虑的是,任意取代的非芳香族含氮杂环基团;

本发明所公开的化合物是CRTH2活性的有效抑制剂,例如,被认为可以用于治疗和预防以CRTH2活性介导的疾病,不限于此地包括炎性疾病,例如(过敏性)哮喘、特应性皮炎、过敏性鼻炎、系统性过敏症、超敏感性反应、药物过敏(例如青霉素、头孢菌素)、昆虫叮刺过敏、慢性梗阻性肺病(COPD)和炎性皮肤病,例如皮炎、湿疹、过敏性接触性皮炎,风疹,动脉粥样硬化,再狭窄,肌炎(包括多肌炎,皮肌炎)和与炎性成分有关的其它疾病,例如风湿性关节炎、骨关节炎、炎性肠疾病(IBD)。
本发明的详细描述
本发明涉及Th2细胞上表达的化学吸引剂受体同源分子、本文也称为“CRTH2”的抑制剂。前列腺素PGD2是CRTH2的天然配体,其结合CRTH2并至少诱导了部分促炎活性。因此,本发明公开的化合物可以用于抑制CRTH2活性;可以用于抑制前列腺素D2活性并且可以用于抑制或者治疗(治疗学方面或者预防学方面)由CRTH2和/或PGD2介导的炎性疾病与过敏性症状。表达CRTH2的免疫系统细胞包括Th2细胞、嗜曙红细胞和嗜碱细胞。因此,本发明公开的化合物可以优选用于抑制由上述细胞介导的炎性疾病和过敏性症状。
