Description
技术领域
本发明涉及一种噻唑烷二酮类HDAC抑制剂、制备方法及应用,属于医药技术领域。
背景技术
传统的恶性肿瘤治疗方法主要包括手术治疗、化学治疗、放射治疗。手术治疗虽然是一种较好的方法,但如果不继续进行其他的辅助治疗,对于延长患者生命的效果并不理想;化学治疗可能会有耐药性的产生,产生药物的副作用,常见的有对骨髓的抑制,对肠道功能的抑制等;放射治疗是一种局部治疗,放疗可以抑制肿瘤的生长,但另一方面也会对周围组织产生影响以及造成损伤。分子靶向治疗因特异性强和毒性低等特点成为治疗癌症的新方法。在不影响DNA序列的情况下,通过对DNA等遗传物质的甲基化修饰、乙酰化修饰、染色质构象改变等改变个体发育并遗传给后代,研究这种机制的学科即为表观遗传学。表观遗传调控在许多生物过程中起到至关重要的作用,并与癌症等各种人类疾病的发生和进展息息相关。人类基因组包含20000至25000个基因,仅由DNA序列的5 %编码,然而,并非是一个基因对应着一蛋白质,因为信使核糖核酸在编译等过程后会导致转录组比基因数量高出数倍,其中就包括在蛋白质合成后,通过氨基酸侧链的翻译后修饰(posttranslationalmodification,PTM)发生的进一步的扩增。大多数 PTM本质上是动态的,能使单个蛋白质能够以多种功能状态存在,并以可逆的方式从一种状态变化到另一种状态。其中,特别是赖氨酸的ε-氨基侧链,可以通过烷基化或酰化等多种 PTM产生各种修饰后的蛋白质。例如,烷基化增加了赖氨酸侧链的长度,同时在生理pH下保持其带正电的性质,而酰化则会产生中性甚至带负电荷的侧链,酰化的范围从甲酰化到蛋白质如泛素的结合。在这些PTM中,乙酰化和甲基化,常发生在富含赖氨酸的组蛋白 N 末端,在染色质结构的表观遗传调控和基因转录过程中配体的募集中发挥核心作用,因此,参与到赖氨酸乙酰化、甲基化以及去除乙酰或甲基化的酶已成为小分子药物发现的重要靶点。而赖氨酸乙酰化在20世纪60年代初首次在组蛋白中观察到,其可以显著地改变蛋白质的生物学特性,例如改变蛋白结合、改变蛋白稳定性、降低相关酶的催化活性等。在此后不久,发现了催化乙酰化反应和脱乙酰化反应的酶,并将其分别命名为组蛋白乙酰转移酶(histone acetyltransferase,HAT)和组蛋白去乙酰化酶。恶性肿瘤目前是人类的最大威胁之一,人类积极的在各领域寻找缓治以及解决该疾病的方法,而在化学治疗方面,抑制组蛋白去乙酰化酶已经经过大量研究证明对许多癌症都有相当好的治疗效果。但尽管经过了三十多年的研究,现有的临床候选HDAC抑制剂仍旧存在药代动力学性质不佳、药效一般、适应症有限等问题,没有完全发挥HDAC靶点的联用优势,并且已上市的HDAC抑制剂种类较少,所以该靶点仍具有很高的研究价值以及研究空间。
