( 2E) -3-苯基 -N- [2, 2, 2-三氯 -1 - [ [ (8-喹琳基氨基) 硫代甲基]氨基]乙基] -2-丙烯酰胺及其医药用途 技术领域
本发明涉及医药化学领域, 具体地, 本发明涉及一种新型丙烯 酰胺类化合物( 2E) -3-苯基 -N- [2, 2, 2-三氯 -1- [ [ (8-喹啉基氨基) 硫代甲基]氨基]乙基] -2-丙烯酰胺及其药物组合物, 本发明还涉 及所述化合物及其药物组合物用于抗细胞凋亡,预防或治疗与细胞 凋亡有关的疾病或症状的用途, 特别是用于保护心肌细胞和预防 或治疗与心肌细胞凋亡有关的疾病或症状中的用途。 背景技术
细胞凋亡一般是指机体细胞在发育过程中或在某些因素作用 下, 通过细胞内基因及其产物的调控而发生的一种程序性细胞死 亡。 细胞凋亡普遍存在于生物界, 既发生于生理状态下, 也发生于 病理状态下。 对胚胎发育及形态发生、 组织内正常细胞群的稳定、 机体的防御和免疫反应、 疾病或中毒时引起的细胞损伤、 老化、 肿 瘤的发生进展起着重要作用, 一直是生物医学研究的热点。
研究表明, 有很多重大疾病的发生都与细胞过度凋亡有关, 例 如在艾滋病的发展过程中, CD4+ T细胞数目的减少; 移植排斥反应 中, 细胞毒性 T细胞介导的细胞死亡; 缺血及再灌注损伤, 心肌细 胞和神经细胞的凋亡; 神经系统退化性疾病(如阿尔海默次病、 帕 金森氏症等) ; 暴露于电离辐射引起的多种组织细胞凋亡等。
有证据表明, 心肌细胞凋亡与许多心脏疾病的发生、 发展和 预后有着密切的关系。 通过研究心肌细胞凋亡发现梗死的心肌死 亡不等于心肌坏死, 凋亡是心肌梗死的机制之一, 而且是梗死早 期心肌死亡及缺血 /再灌注所致的心肌死亡的主要方式,此时心肌 的大量凋亡, 加重了心肌的破坏。 1989年, Nepomniashchikh等 观察饥饿性心肌萎缩超微结构时发现, 心肌细胞结构蛋白合成降 低, 细胞数减少, 但不伴细胞核相应成比例地减少, 由此初步提 出饥饿性心肌萎缩是由细胞凋亡所致。 1994 年, Got t l ieb 和 Kawano等采用电镜结合 DNA凝胶电泳方法取得了心肌细胞凋亡的 直接证据, 前者揭示再灌注损伤诱发兔心肌细胞凋亡, 后者证实 心肌炎患者伴发心肌细^凋亡。 Tanaka 等培养的乳鼠心肌细胞 中,也证明了凋亡的存在。 由于方法学的进步和凋亡的研究深入, 已在多种心脏病中发现心肌细胞凋亡的病理作用。 研究表明, 自 发性高血压小鼠(SHR)心脏损害与凋亡有关;晚期由肥厚心脏转向 心力衰竭为心肌细胞凋亡所致; 急性心梗除坏死外, 梗塞早期和 再灌注损伤也诱发凋亡; 心肌细胞凋亡同样见于移植的心脏和右 室发育不良性心肌病, 缺氧同样诱导心肌细胞凋亡。
凋亡在某种程度上具有可复性,心肌梗死和缺血 /再灌注中的 细胞凋亡有其特点和规律,利用其特点可以预防和减少细胞凋亡, 为临床预防缺血 /再灌注损伤提供启示; 在再灌注过程中,产生收 缩带区域(梗死灶周围) 的细胞凋亡是由一些诱因诱导产生的, 可以利用凋亡的抑制因素如药物等来预防凋亡, 治疗凋亡引起的 ϋ>έ ^^。
但目前可供临床应用的用于抗细胞凋亡和保护细胞的药物种 类和数量还很少, 选择性和靶向性都不高, 因此不断研究开发新的 安全有效的抗细胞凋亡和保护细胞的药物, 尤其是具有全新作用机 制的药物具有十分重要的意义。 发明内容 本发明的目的是寻找并且开发抑制心肌细胞凋亡的小分子化 合物, 用来预防或治疗心肌细胞凋亡导致的各种病理改变。 发明 人经过长期、 大量的实验研究, 发现了一种丙烯酰胺类化合物, 其 具有抗细胞凋亡,保护心肌细胞的作用, 能够用于预防或治疗与心 肌细胞凋亡有关的疾病或症状。 具体地,

高内涵筛选分析法:
细胞发生凋亡时, 通常会出现细胞形态学的显著改变, 以及 生化和分子标志物等一系列变化。关于细胞凋亡的检测方法很多, 但大多只能针对凋亡细胞的凋亡单一指标进行检测。 高内涵筛选 分析是近年来新出现的一种凋亡检测方法, 通过特定的荧光染色 对凋亡同时进行多因素分析。 主要分析与凋亡过程相关的三个参 数: 包括核形态学改变, 线粒体肿胀和或线粒体膜电位, F-肌动 蛋白含量。 对于完整的细胞具有高度的特异性和可靠性。
发生凋亡的细胞通常表现出两种类型的核改变, 核片段化或 核浓缩, 在核片段化的过程中, 圆形或椭圆形的核变成分叶状, 并最终裂解成多个亚核结构。 由于细胞核内的常染色体、 核仁等 结构成份的破坏使核密度增加。 HCS Reader能通过 Hoechs t染色 对细胞核的形态学进行观测, 并对细胞核面积和核强度进行定量 比较。
线粒体内的变化是凋亡重要的形态学改变,线粒体通过外膜 释放凋亡基因因子, 同时, 因为线粒体通透性增加, 也可以使线 粒体内膜的电化学成份改变, 导致膜电位的下降或消失。 在凋亡 的刺激下, 线粒体也扩张变大,引起线粒体体积的增加。线粒体膜 电位的下降和线粒体体积的增加, 已经被公认为是细胞凋亡早期 的标志物, 可通过线粒体示踪剂 Mi toTracker® Red来进行定量。
肌动蛋白细胞骨架的变化已经被报道作为一个与凋亡改变有 关的重要参数, 在早期凋亡时, F-肌动蛋白含量增加。 通过 F -肌 动蛋白特异的染色剂 Alexa Fluor® 488 Phalloidin (次毒蕈环 肽) 的染色, 可确定 F-肌动蛋白含量, 对细胞凋亡的程度进行 量化比较。
