Abstract
本发明公开了一类通式(I)所示的吲唑及四氢吲唑类化合物,这类化合物的制备方法、含有这类化合物的药物组合物,本发明的化合物因具有对肝葡萄糖利用和摄取的促进作用及较低的肝毒性,因此可以用于制备抗糖尿病药物,降低糖尿病病人的血糖浓度及抑制糖尿病病人并发症的发生。
Description
技术领域:
本发明涉及药物化学和2型糖尿病治疗学领域,具体涉及具有降糖活性的吲唑或四氢吲唑类化合物及其制备方法和用途。
技术背景:
随着人们生活方式的改变和人口老龄化问题的加剧,糖尿病正在成为世界第三大严重的慢性非传染性疾病,其主要特征为高血糖。据估计,到2010年,全球2型糖尿病患者人数将达到两亿。临床上将糖尿病分为两型:1型糖尿病,是由于胰岛β细胞损害引起胰岛素分泌水平绝对降低而导致高血糖,约占糖尿病人的5~10%,其治疗需要外源性地给予胰岛素;大约90%以上的患者为2型糖尿病人,是由于胰岛素分泌的相对不足及胰岛素作用环节不健全而导致血糖水平升高,可通过化学药物促使β细胞分泌更多胰岛素,或改善靶组织对胰岛素的敏感性来进行治疗。因此,研究提高胰岛素的敏感性,包括促进器官组织对葡萄糖的吸收利用和摄取,成为糖尿病药物研究的重要课题。
治疗糖尿病的药物主要有以下几大类:1、促进胰岛素分泌的化学物质,包括磺酰脲类如格列美脲和非磺酰脲类(又分为苯基丙酸类衍生物,苯甲酸衍生物,肽酶抑制剂等几种);2、胰岛素增敏剂,包括PPARγ激动剂(其中又分为噻唑烷二酮类和非噻唑烷二酮类),PPARα和PPARγ的共同激动剂,维甲酸受体(retinoid Xreceptor,RXR)激动剂,β3肾上腺素能受体激动剂等;3、肝糖生成抑制剂,包括糖原磷酸化酶抑制剂和葡萄糖-6-磷酸酶抑制剂,抑制了这两个酶的活性,就可以抑制肝糖原向葡萄糖转化;4、α-糖苷酶抑制剂,它可以降低餐后血糖水平,如放线菌属微生物培养液中分离得到的阿卡波糖;5、蛋白质酪氨酸磷酸酶1B(PTP-1B)抑制剂,它具有胰岛素增敏和拮抗肥胖的作用。
研究表明胰岛素抵抗是导致肥胖及2型糖尿病的一个关键因素,因此,胰岛素增敏剂噻唑烷二酮类PPARγ激动剂的出现,无疑给糖尿病药物市场带来了巨大的生机和活力。噻唑烷二酮类(TZDs)药物作为PPARγ的选择型配体,因其在改善糖耐量,降低血糖,改善脂质代谢,改善高胰岛素血症方面的显著效果,近年来备受关注。
第一个应用于临床的噻唑烷二酮类胰岛素增敏剂是由日本Sankyo公司研制的曲格列酮(Troglitazone),1997年在美国上市。第一代噻唑烷二酮类胰岛素增敏剂除曲格列酮外,还包括齐格列酮(Ciglitazone)、恩格列酮(Englitazone),第二代药物有吡格列酮(Pioglitazone)、罗格列酮(Rosiglitazone)等,它们与PPARγ受体的结合力及抗糖尿病作用强弱顺序为:罗格列酮>吡格列酮>曲格列酮>齐格列酮>恩格列酮。长期的临床研究发现,曲格列酮具有较严重的肝毒性,已于2000年从欧美及日本市场撤出。FDA亦提请注意罗格列酮的肝毒性问题。因此,寻找新一代高效、毒副作用低的胰岛素增敏剂,成为抗糖尿病药物研发领域的研究热点。
