Description
技术领域
本发明涉及具有优异的二肽基肽酶IV(以下简称为“DPP-IV”)的阻碍作用、对二型糖尿病的治疗或预防、二型糖尿病附带的合并症的治疗或预防、或其它的与DPP-IV有关的病情的治疗有用的化合物或其医药上所允许的盐的化合物。
背景技术
DPP-IV是从多肽链的N末端特异性水解Xaa-Pro或Xaa-Ala(Xaa可以是任意的氨基酸)的二肽的丝氨酸蛋白水解酶的一种。DPP-IV(也称为CD26)在生物体内的作用、与疾病的关系还并不完全清楚,但有各种报告。尤其是,作为与胰高血糖素样肽1(以下简记为GLP-1)的惰性化有关的酶的作用最近倍受注目。
GLP-1是单独时不诱导胰岛素分泌而具有增强由糖引起的胰岛素分泌的作用的肽激素。因此,能够期望降低低血糖的危险性、促进对应于血糖浓度的胰岛素分泌。再者,也有暗示GLP-1具有抑制摄食作用的报告。但是,因为GLP-1被DPP-IV迅速分解,所以GLP-1本身难以作为药剂。因此,对GLP-1的肽类似物进行了研究,但都是注射剂而不是经口制剂。
因此所考虑的是,通过阻碍作为分解酶的DPP-IV,可抑制GLP-1的分解,提高GLP-1的作用。这是因为通过经口投给DPP-IV阻碍剂,可维持GLP-1的体液中浓度,利用该GLP-1的作用,预防或治疗糖尿病等特别是二型糖尿病。人们也期望这样的治疗法对因被破坏的耐糖能力而引起或加重的其它疾病例如过血糖(饭后过血糖)、高胰岛素血症、糖尿病合并症(肾障碍、神经障碍等)、脂质代射异常、肥胖等的预防或治疗效果。而且人们也期望GLP-1通过增强摄食抑制作用而对期待改善的疾病例如吃得过多、肥胖等的预防或治疗效果。
另一方面,就DPP-IV的作用而言,除此之外,还报告有神经肽的分解、T细胞的活性化、对转移性肿瘤细胞的内皮的粘接、HIV病毒对淋巴球的侵入等。再者,就与DPP-IV有关的实际知识而言,已知的是提高了风湿病患者的末梢血T细胞的DPP-IV阳性率和在肾炎患者的尿中DPP-IV活性高。因此,也期望着阻碍DPP-IV的物质对自身免疫疾病(例如关节炎、慢性间接风湿病)、骨质疏松、后天性免疫不全综合征(AIDS)、移植器官组织的排异反应等具有预防或治疗效果。
已有关于DPP-IV阻碍药的专利申请。WO02/51836、WO01/96295、US20020193390、US6011155以及特表平9-509921号中公开了2-氰基吡咯烷衍生物,WO97/40832中公开了氨基酰基噻唑烷酯(thiazolidide)衍生物。另外,在“Annual Report in Medicinal Chemistry第36卷、第191-200页、2001年”中,除上述化合物组以外,还报告了:作为肽衍生物的氨基酰基吡咯烷酯(pyrrolidide)衍生物、二肽膦酸酯衍生物、二肽硼酸衍生物、四氢异喹啉衍生物、环状肽衍生物、或者作为非肽衍生物的N-苯基酞酰亚胺衍生物、N-苯基均酞酰亚胺衍生物、异喹啉衍生物。
发明内容
迄今为止,已报告了许多DPP-IV阻碍药,但任一种化合物在阻碍活性、稳定性、安全性方面都不能说充分,还没有可满足作为医药品的阻碍药。因此,人们期望开发出一种因DPP-IV阻碍作用而具有治疗或预防效果且可充分满足作为医药品的化合物。
本发明人等鉴于上述问题点,以开发出新的DPP-IV阻碍药为目的而进行了专心研究。其结果是,本发明人等发现:侧链具有适当的疏水性的二环式环特别是二环式杂环基的用下述通式表示的化合物具有强力的DPP-IV阻碍活性,而且在提高其稳定性方向上进行化合物展开,从而完成了本发明。
即,本发明提供一种用以下的式(I)表示的化合物或作为其医药上所允许的盐的化合物,
(式中,R1、R2同时或分别表示氢原子、可被取代的C1-6烷基或-COOR5,或,用R1和R2和根部的碳原子表示三~六元的环烷基,而且,R5表示氢原子或可被取代的C1-6烷基,R3表示氢原子或可被取代的C6-10芳基,R4表示氢原子或氰基,D表示-CONR6-、-CO-或-NR6CO-,R6表示氢原子或可被取代的C1-6烷基,E表示-(CH2)m-(m为1~3的整数)、-CH2OCH2-或-SCH2-,n表示0~3的整数,A表示可被取代的二环式杂环基或二环式烃基。),这些化合物在本说明书中以后称为“本发明化合物”。
本发明还提供一种以上述本发明化合物为有效成份的DPP-IV阻碍剂。该DPP-IV阻碍剂成为通过阻碍DPP-IV活性而期待改善病情的疾病例如糖尿病(特别是二型糖尿病)、糖尿病合并症等的预防或治疗剂。

(S)-2,7-二甲基吡唑并[1,5-a]嘧啶-6-羧酸{2-[(2-氰基吡咯烷
-1-基)-2-氧代乙氨基]-2-甲基丙基}酰胺
将N,N-羰基二咪唑(930mg)添加到2,7-二甲基吡唑并[1,5-a]嘧啶-6-羧酸(1.00g)的四氢呋喃(30ml)溶液中,在室温下搅拌4小时。在用冰冷却的条件下,将该搅拌后的溶液慢慢滴下到(S)-1-[(2-氨基-1,1-二甲基乙基)氨基乙酰基]吡咯烷-2-腈二盐酸盐(1.56g)、三乙胺(3.6ml)的四氢呋喃(30ml)溶液中。回到室温,搅拌一宿。在减压下浓缩,将二氯甲烷添加到残渣中。滤去不溶物,在减压下浓缩滤液。将残渣供给到柱色谱(流出溶剂:二氯甲烷∶甲醇50∶1),得到题述化合物(690mg,Y.33%)。在10℃下,将4N盐酸/1,4-二噁烷(0.50ml)添加到所得到的化合物(690mg)的1,4-二噁烷(5.0ml)溶液中,搅拌10分钟。添加醚,滤取析出的结晶。在减压下干燥,得到黄色结晶的题述化合物的盐酸盐(670mg,Y.90%)。

[药理试验例1]
为了进行DPP-IV阻碍剂的筛选,使用了以甘氨酰-脯氨酸-4-甲基香豆基-7-酰胺(Gly-Pro-MCA)为基质的以下的方法。
将溶解于测定缓冲液(含有氯化钠(140mM)、氯化钾(10mM)、1%牛血清白蛋白的三羟甲基氨基甲烷盐酸缓冲液(25mM)pH7.4)的各种浓度的被检物质(40μl)以及150μM Gly-Pro-MCA基质(40μl)添加在96孔微量滴定板中,混合后,在室温下静置5分钟。然后,添加用测定缓冲液稀释30倍的血浆(20μl)并搅拌,在暗室内,在室温下使之反应30分钟。添加1M乙酸缓冲液pH4.2(100μl),停止反应,测定了因DPP-IV活性而游离的MCA在360nm激发所得到的465nm的荧光。以按照以下的公式算出的DPP-IV活性为基础,求出被检物质阻碍50%DPP-IV活性的浓度(IC50)。结果如表28所示。另外,就比较药剂而言,使用专利(WO97/40832)记载的异亮氨酰基噻唑烷酯(化合物A)。
DPP-IV阻碍活性=100×(1-(Fs-Fb)/F100-Fb)
F100:在用血浆的反应中得到的萤光强度
Fb:添加反应停止液而进行反应时的空白萤光强度
Fs:添加被检物质而得到的萤光强度
表28
由本试验结果可知:本发明化合物显示出数十nM的IC50值,与化合物A(IC50:225nM)相比,具有强力的DPP-IV阻碍活性。
[药理试验例2]
使用Wistar/ST系雄性大白鼠((株)日本ェスェルシ一),驯化五天以上之后(使用时为8周龄),绝食一夜。以(5ml/kg)的比例经口投给实施例1的化合物(3mg/kg)、实施例61的化合物(1mg/kg)以及化合物A(10mg/kg),30分钟后,经口投给20%葡萄糖溶液(5ml/kg)(相当于葡萄糖(1g/kg))。经过一段时间后由尾前端部采血,进行血浆分离,测定血中葡萄糖以及胰岛素浓度。血中葡萄糖浓度使用グルテスト((株)三和化学研究所)来测定,血浆中胰岛素浓度使用市售的EAIキット((株)シバャギ)来测定。
结果如表29所示。其中,血中葡萄糖浓度表示根据从投给糖到60分钟后的各采血时间的血糖值算出曲线下面积(min·mg/dl)的值(其中,作为0分钟的血糖值,以试验开始前的采血而得到的试样的血糖值代用),血浆中胰岛素浓度用投给化合物10分钟后的血浆中胰岛素浓度(pg/ml)来表示。
表29
给药组 | 血糖值(min·mg/dl) | 胰岛素(pg/ml) |
水 | 8199±235 | 1692±583 |
化合物A | 6671±161 | 2994±310 |
实施例1 | 7024±222 | 2745±574 |
给药组 | 血糖值(min·mg/dl) | 胰岛素(pg/ml) |
水 | 8208±368 | 2008±666 |
化合物A | 6769±128 | 3670±827 |
实施例61 | 7055±287 | 4093±1050 |
由本实验结果可知:本发明化合物显示出基于胰岛素分泌作用的血糖降低作用。
如以上所示那样,本发明化合物是显示出强力的DPP-IV阻碍活性、化学性稳定、酶选择性优异的没有副作用等的安全的化合物,因此,对治疗糖尿病(特别是二型糖尿病)、附随糖尿病而产生的合并症以及肥胖等是有用的。
