Description

一种Rho激酶抑制剂及其制备方法和应用
本申请是以CN申请号为201811275571.0,申请日为2018年10月30日的申请为基础,并主张其优先权,该CN申请的公开内容在此作为整体引入本申请中。
技术领域
本申请属于化学药物领域,具体涉及一种Rho激酶抑制剂及其制备方法和应用。
背景技术
Rho激酶(Rho-associated protein kinase,ROCK)为最早发现的Rho蛋白下游靶点之一,是一类相对分子质量为160kDa的丝氨酸/苏氨酸蛋白激酶,包括ROCKI和ROCKII两种亚型;其分子结构包括氨基端的激酶催化结构域(kinase domain/catalytic domain,CD)、中央的Rho结合的卷曲螺旋结构域(coiled-coil domain comprising a Rho binding domain)、羧基端的血小板白细胞C激酶底物同源性结构域(pleckstrin-homology domain,PH)和半胱氨酸富集结构域(cysteine-rich domain,CRD)。研究发现,ROCK参与多种细胞功能,如平滑肌收缩、应力纤维形成、细胞骨架重构、细胞分化与迁移、细胞凋亡等,并且在多种心脑血管疾病的病理过程中,均发现ROCK过度表达的现象。
到目前为止,发现的ROCK抑制剂均为小分子有机化合物,主要为异喹啉类、4-氨基吡啶类、吲唑类、酰胺和脲类等。这些小分子抑制剂与Rho激酶催化结构域的ATP结合位点结合而起效。由于蛋白激酶中ATP结合位点区域的氨基酸序列有高度的同源性,因此上述小分子抑制剂在对ROCK产生阻断的作用同时,也能拮抗PKA,PKG和PKC等蛋白激酶,这就不可避免地造成了一定的不良反应。
鉴于此,本申请提供了一种新型的Rho激酶抑制剂,来高选择性地拮抗ROCK。

为了评价本申请化合物的药效及其细胞毒性,进行如下试验例。
试验例1本申请化合物对大鼠蛛网膜下腔出血的作用
(1)模型建立方法
采用血管内穿刺法制作大鼠蛛网膜下腔出血(SAH)模型。大鼠称重后用戊巴比妥钠麻醉(50mg/kg)或水合氯醛(300mg/kg)腹腔注射麻醉后,仰卧固定,维持动物体温于37℃左右。大鼠颈部备皮,取颈部正中切口,沿胸锁乳突肌内缘分离肌肉和筋膜,暴露右侧颈总动脉主干及其分叉处,显露颈外动脉及颈内动脉。分离出颈外动脉 分支枕动脉及甲状腺上动脉将其结扎。
将颈内动脉分支处以眼科镊轻轻夹住,以6号注射器针头刺破颈内动脉和颈外动脉分支处,稍微松开夹住颈内动脉分支的眼科镊,用3号鱼线于出血点处进行穿刺,松开颈内动脉上的眼科镊,将鱼线向颅内插入。当穿刺线头端距颈总动脉分叉处约18~19mm后,有阻力感,表示穿刺线头端已达大脑前动脉与大脑中动脉分叉处,略用力再伸入约2mm后,此时穿刺线已刺破大脑前动脉与大脑中动脉分叉,停留15秒后,完全拔除穿刺线,压迫止血后缝合皮肤。肌肉注射160万单位青霉素钾(40万单位/ml,0.2ml/只),避免伤口感染。假手术组只是当穿刺线刺入感到阻力时退出,不刺破大脑前动脉与大脑中动脉分叉,其余操作步骤与模型组相同。手术后将大鼠转移至保温毯,至基本恢复清醒后转入鼠笼,正常饲养。
(2)实验方法
本次试验设置32个组别,依次为第1-32组,第1组为正常对照组(健康大鼠)、第2组为假手术对照组(不穿刺造模)、第3组为模型对照组(穿刺造模,给予生理盐水)、第4组为阳性对照组(穿刺造模,给予盐酸法舒地尔注射液)、第5-32组为本申请化合物测试组(穿刺造模,分别给予本化合物测试),每组8只动物(购自斯贝福(北京)生物技术有限公司,合格证号为SYXK(京)2016-0002),雌雄各半。造模前禁食不禁水12-18h,模型构建后通过尾静脉注射完成给药一次,4h后给药第二次,共给药2次,给药体积为2ml/kg;第1-3组注射生理盐水,第4组给予盐酸法舒地尔注射液(依立卢,购自旭化成制药株式会社),第5-32组分别注射本申请制备的浓度为15g/L的化合物YK1600-1~YK1612、R-YK1600-1~R-YK1612的溶液(制备方法:在1000mL的注射用水中加入15g本申请化合物,再分别加入8g氯化钠,溶解后用0.5mol/L氢氧化钠溶液调节pH为6.0)。首次给药24h后安乐死大鼠,取脑,根据Sugawara的方法(参考文献:Sugawara T,Ayer R,Jadhav V,et al.A new grading system evaluating bleeding scale in filament perforation subarachnoid hemorrhage rat model.J Neurosci Methods.2008,167(2):327-34.)对蛛网膜下腔出血量进行评分,评分结果如下:

本试验例设置31个组别,依次为第1-31组,第1组为空白对照组、第2组为正常对照组、第3组为阳性对照组、第4-31组为本申请化合物组。试验操作具体为:96孔板每孔加入100μL密度为5×10 4的内皮细胞EA.hy926(购自苏州北纳创联生物技术有限公司),转入培养箱中以37℃5%CO 2和饱和湿度的条件培养24h,加入100μL 2× 以含10%胎牛血清的DMEM培养基配制和稀释的受试物溶液,其中阳性对照组中的所加的受试物为不同浓度的盐酸法舒地尔(购自北京四环制药有限公司,国药准字H20173349)溶液,空白对照组加入等体积的DMEM培养基,正常对照组加入等体积的PBS缓冲液,每个浓度点设一个复孔。加入受试物后转入培养箱继续培养24h,每孔加入20μL CCK-8检测液(购自北京索莱宝科技有限公司,批号:CA1210),37℃作用2.5h,振荡混匀后检测450nm处的吸光度值。
检测OD值,按细胞活力计算公式计算不同浓度药物组细胞活力,公式如下:
细胞活力=(A 药物组-A 空白对照)/(A 正常对照-A 空白对照)*100%
其中A为450nm处的吸光度值。
采用Prism6.0做抑制剂浓度-活力曲线,计算受试物的IC 50,其相关系数R 2>0.99;盐酸法舒地尔、R-YK1601、R-YK1603、R-YK1606、R-YK1607、R-YK1610的抑制剂浓度-活力曲线详见附图1-6,其中横坐标为受试物浓度的以10为底数的对数,纵坐标为细胞活性(即,细胞活力)。

Figure PCTCN2019085689-appb-000216
注:受试物浓度从1000μmol/L按5倍稀释梯度向下稀释至0.32μmol/L。
从表6中可以看出,本申请的化合物对EA.hy926细胞的IC 50都在80μM以上,均大于上市药物盐酸法舒地尔对EA.hy926细胞的IC 50。也就是说,本申请的化合物细胞毒性均小于法舒地尔,安全性均大于法舒地尔。
