Description
技术领域:
本发明属于医药技术领域,涉及一种具有HDAC6抑制活性和抗肿瘤活性的4-亚甲基-N-羟基苯甲酰胺类化合物以及在制备组蛋白去乙酰化酶抑制剂及其在制备用于治疗和/或预防癌症药物中的用途。
背景技术:
组蛋白去乙酰化酶(histone deacetylase,HDAC)异常表达与肿瘤、神经退行性疾病和自身免疫性疾病等疾病相关。HDAC6结构和功能有别于其他亚型,研究发现HDAC6选择性小分子抑制剂,不仅有利于深入探索HDAC6的生物学功能,而且可能发现新型抗肿瘤活性化合物。HDAC6作为HDAC家族中最大的亚型,由1215个氨基酸残基组成,主要存在于细胞质中。与其他亚型不同,HDAC6是唯一一个具有两个串联的同源催化域(CD1和CD2)的亚型,这两个同源催化域分别位于N-末端和中心区域。在C-末端有一个锌指泛素结合域,负责与泛素蛋白酶体和聚集体途径的相互作用,清除错误折叠的蛋白质。HDAC6还有两个富含亮氨酸的核输出信号区(nuclear export signal,NES),负责使HDAC6靶向位于细胞质中的非组蛋白底物,例如:α-微管蛋白(α-tubulin)、tau蛋白、皮质区肌动蛋白(cortactin)、热休克蛋白90(heat shock protein90,HSP90)和过氧化物还原酶(peroxiredoxin)等。HDAC6还具有一个富含精氨酸和赖氨酸序列的核定位信号区(nuclear localization signal,NLS),与NES共同控制HDAC6细胞核和细胞质的移动;以及一个含有八个连续的丝氨酸-谷氨酸十四肽的重复序列(Ser-Glu-containing tetrapeptide,SE14),负责HDAC6与tau蛋白的相互作用。
鉴于HDAC6在多种疾病中所发挥的重要作用,选择性抑制HDAC6近年来成为一种新型的治疗策略。Tubacin是第一个被发现的HDAC6抑制剂,它对HDAC6的IC50为4nM,是HDAC1(IC50=1400nM)的350倍左右,但是生物利用度较差。Ricolinostat(ACY1215)是临床研究最为深入的一个HDAC6抑制剂,目前处于临床I/II期的研究。它对HDAC6的IC50为4.7nM,相对于HDAC1、HDAC2和HDAC3,选择性分别约为15倍,18倍和16倍。ACY1215已在各种多中心I/II期临床试验中得到充分研究,包括单独治疗、与地塞米松和硼替佐米或来那度胺联合治疗复发或难治性多发性骨髓瘤。尽管已有许多研究报道了选择性HDAC6抑制剂的临床前研究,但只有ACY1215和ACY241进入I/Ⅱ期临床试验。现在设计有效和选择性HDAC6抑制剂的主要考虑因素是提高化合物的选择性以及改善化合物较差的生物利用度。

实施例83:发明产物的药理作用研究
实验设阳性对照组(伏立诺他、ACY1215和Tubacin)。以重组rHDAC1、2、3及rHDAC6蛋白(BPS Bioscience,USA)为亚型酶源。所有反应均在96孔板中进行。反应缓冲液包含25mM Tris-HCl(pH 8.0),137mM NaCl,2.7mM KCl,1mM MgCl2及0.1mg/mL BSA。分别选取2μM、400nM、80nM、16nM、3.125nM,5个梯度浓度的化合物溶液(5μL)及酶(5μL)于25℃预孵育15min,随后加入荧光底物Boc–Lys(Ac)–AMC(5μL)起始反应,于37℃孵育60min。最后向体系中加入含Trypsin及SAHA的终止缓冲液(25μL),再孵育10min。以激发波长355nm,发射波长460nm,测量荧光强度(Thermo Scientific Varioskan Flash Station)。以GraphPad计算IC50。目标化合物对HDAC的抑制活性见表1。
表1目标化合物对HDAC的抑制活性
上述实验结果表明,本发明目标化合物对HDAC6都表现出一定的抑制活性,其中实施例6、实施例36、实施例82等24个化合物对HDAC6的抑制活性优于ACY1215,IC50在0.2-8.6nM之间,实施例6的活性最佳,IC50达到0.2nM;实施例8、实施例44、实施例70等20个化合物对HDAC6的选择性均优于Tubacin,对HDAC6选择性在100-3500之间,化合物实施例8的选择性最高,选择性达到3500;由此可见本发明发现一系列具有较高活性与选择性的HDAC6选择性抑制剂,可用于抗肿瘤活性研究,即所得本发明的化合物具有很好的工业应用前景。
