Abstract
本发明公开了一种式Ⅰ所示的化合物、或其立体异构体、或其药学上可接受的盐、或其溶剂合物、或其前体药物、或其代谢产物。试验表明,本发明的化合物具有良好的ROCK抑制活性,可以有效用于与ROCK活性异常疾病的治疗,为临床治疗与ROCK活性异常相关的疾病提供了一种新的药用可能。
Description
技术领域
本发明涉及一种抑制ROCK的化合物及其在治疗与ROCK相关疾病中的应用。
背景技术
Rho属于小分子单聚体GTPase超家族,是Ras超家族的哺乳动物基因同系物,通过其下游最主要的效应分子Rho激酶(Rho-associated coiled-coil containing proteinkinase,ROCK),来调节细胞肌动蛋白骨架的重组,从而广泛参与细胞有丝分裂、细胞骨架调整、平滑肌细胞收缩、神经再生、肿瘤细胞浸润、细胞凋亡的调节等一系列生物学过程。Rho/ROCK激活后可以作用于多种底物,从而产生生物学过程。最主要的两种底物是肌球蛋白轻链(MLC)和肌球蛋白轻链磷酸酶(MLCP),MLC的磷酸化水平是决定平滑肌收缩程度的一个重要因素。肌球蛋白轻链激酶(MLCK)磷酸化MLC的Ser-19位点,导致平滑肌收缩;MLCP的抑制可以使MLC的磷酸化和平滑肌的收缩进一步增强。ROCK被激活以后,本身可以将MLC磷酸化而发生肌丝收缩作用;同时也能将MLCP磷酸化,使MLCP失活,导致细胞胞浆内MLC磷酸化程度增高,间接促进肌丝收缩。
在动物模型中Rho激酶活性的抑制展现出治疗人类疾病的多种益处,包括心血管疾病如肺动脉高压、高血压、动脉粥样硬化、心脏肥大、高眼压、脑缺血、脑血管痉挛等,和中枢神经系统病症如神经元变性等,以及肿瘤。研究表明ROCK表达和活性在自发性高血压大鼠中有所升高,说明其与这些动物高血压的发生具有关联(Involvement of Rho-kinasein hypertensive vascular disease:a novel therapeutic target in hypertension[J].FASEB J.,2001,15(6):1062-4)。ROCK抑制剂Y-27632可使三种大鼠高血压模型(自发性高血压、肾性高血压、醋酸脱氧皮质酮盐型高血压)中的血压显著降低,而对对照大鼠的血压作用较小(Calcium sensitization of smooth muscle mediated by a Rho-associated protein kinase in hypertension[J].Nature,1997,389(6654):990-4)。也有研究表明ROCK抑制剂对肺动脉高压具有较好的作用(Acute vasodilator effects of aRho-kinase inhibitor,fasudil,in patients with severe pulmonary hypertension[J].Heart,2005:91(3):391-2)。
目前已上市的ROCK抑制剂药物有Asahi Kasei公司的Eril(适用于脑血管痉挛的治疗)和Kowa公司的Glanatec(适用于高眼压症和青光眼的治疗)。其中Glanatec仅在日本上市销售。因此研究开发作用于ROCK的靶向小分子药物研究,得到活性更好、选择性更高、更低毒性和副作用、更经济的ROCK抑制剂,具有十分重要的社会和经济意义。

为了说明本发明的有益效果,本发明提供以下试验例:
试验例1本发明的化合物生物活性
对本发明的化合物进行了ROCK2抑制活性的检测。
(1)方法
ROCK2抑制活性的检测
ROCK2能够磷酸化S6K(KRRRLASLR)多肽底物,将ATP转化成ADP。在激酶反应后,加入ADP-GloTM试剂,使激酶反应终止,并消耗完剩余的ATP。加入激酶检测试剂,它在使ADP转化成ATP的同时,ATP再被Ultra-GloTM萤光素酶转化成光发光信号,发光信号与激酶活性正相关。
按以下步骤进行ROCK2抑制活性的检测:
1.Assay Buffer:40mM Tris pH 7.5,20mM MgCl2,0.1%BSA(w/v),50μM DTT;
2.加12μL2.5x0.1μg/ml ROCK2工作液进入96孔PCR板;
3.加6μL6x化合物工作液进入96孔PCR板混匀,25℃预孵育10min;
4.加入12μL 2.5x 37.5μg/mlS6K底物和12.5μMATP混合工作液,30℃孵育60min;
5.取25μL反应混合物到一个新96孔PCR板,并加入25μL ADP-GloTM试剂混匀,25℃孵育40min终止反应;
6.取40μL终止反应混合物到一个新96孔PCR板,并加入40μL激酶检测试剂混匀,25℃孵育40min;
7.读取luminescence(冷光)信号值,计算抑制率。
(2)结果
按照上述方法对实施例制备的化合物进行ROCK2抑制活性检测,试验结果见表1,其中测定各化合物的IC50按照说明分类,表1中:
“+”表示IC50测定值大于500nM;
“++”表示IC50测定值小于500nM大于100nM;
“+++”表示IC50测定值小于100nM
表1、化合物对ROCK2的抑制活性
实施例 | ROCK2 | 实施例 | ROCK2 |
1 | ++ | 2 | ++ |
3 | +++ | 4 | ++ |
5 | ++ | 6 | ++ |
7 | ++ | 8 | ++ |
9 | ++ | 10 | + |
11 | ++ | 12 | ++ |
13 | ++ | 14 | +++ |
15 | ++ | 16 | +++ |
17 | +++ | 18 | +++ |
试验表明,本发明实施例的化合物具有良好的ROCK抑制活性,可以有效用于与ROCK活性异常疾病的治疗。
综上所述,本发明公开的式I所示的新化合物,表现出了良好的ROCK抑制活性,为临床治疗与ROCK活性异常相关的疾病提供了一种新的药用可能。
