Definitions

  • Histone deacetylase inhibitor synthesis method thereof and pharmaceutical use
  • the present invention is in the field of medicinal chemistry, and in particular relates to a class of histone deacetylase inhibitors, as well as synthetic methods and pharmaceutical uses of these compounds.
  • Histone deacetylases are a group of organisms that regulate cell chromatin levels, by inducing histone deacetylation, including chromatin recombination, transcriptional activation or inhibition, cell cycle, cell differentiation, and apoptosis. The enzyme of the effect, especially the regulation of transcriptional expression of the gene after activation of the cell.
  • Histone deacetylase inhibitors are a class of compounds that inhibit the activity of HDACs.
  • Histone acetylation plays a very important role in the DNA transcription, replication and repair of chromosomes.
  • Histone deacetylase inhibitors have been used as mood stabilizers and anti-epileptic drugs in the past.
  • attention has been paid to the targeted therapeutic effects of histone deacetylase inhibitors in neurodegenerative diseases.
  • Histone acetylation and deacetylation of chromatin is one of the key aspects regulating gene expression, and abnormal gene expression is the molecular biological basis for tumors and some genetic and metabolic diseases.
  • the degree of histone acetylation is coordinated by histone acetylase (HAT) and histone deacetylase (HDAC).
  • HDAC inhibitors increase the level of chromatin histone acetylation, thus leading to the activation of specific genes, which in turn leads to terminal differentiation of cells or apoptosis of cancer cells. Therefore, HDAC has become one of the most popular targets in the development of cancer chemotherapy drugs.
  • Histone deacetylases are currently known to have 18 different subtypes, which are classified into 4 categories according to their germline: I (HDAC1, 2, 3, 8), II (HDAC4, 5, 6, 7, 9, 10 ), (SIRT1-SIRT7) and IV (HDAC11).
  • I, II and IV are classical families and are Zn 2+ -dependent HDAC.
  • the vast majority of HDAC inhibitors currently in clinical research are capable of inhibiting multiple subtypes of HDAC, which are often part of the Zn 2+ -dependent HDAC family.
  • Histone deacetylase inhibitors can inhibit the activity of HDAC in cells, increase the degree of acetylation of intracellular histones, increase the expression of genes such as P 2J and p53, inhibit the proliferation of tumor cells, induce differentiation and apoptosis.
  • Histone deacetylase inhibitors generally include a zinc ion binding region, a linking region and a surface recognition region. The direct action of the inhibitor with zinc ions is necessary to produce inhibitory activity.
  • HDAC inhibitors mainly include the following four categories: (1) short-chain fatty acids such as butyric acid, phenylbutyric acid and its salts; (2) hydroxamic acids, which are the most widely studied HDAC inhibitors to date.
  • HAHA suberoylanilide hydroxamic acid
  • TSA trichostatin A
  • cyclotetrapeptides cyclic peptides are the most complex class of inhibitors
  • the amino acid macrocycle in the molecule of the cyclic peptide inhibitor acts as a hydrophobic surface recognition region, the alkyl chain serves as a linking region, and the alkyl chain end is linked to a zinc ion binding group such as trapoxin, HC-toxon, Apicidin, FK228 and Largazole et al;
  • benzamides Such compounds are less active than typical hydroxamic acids and cyclic peptides, but have higher selectivity for class I HDACs.
  • MS-275, CI-994 selectivity for class I HDACs.
  • SAHA suberoylanilide hydroxamic acid SAHA
  • vorinostat Zaolinza
  • CTCL metastatic skin T-cell lymphoma
  • FK228 (romidepsin) ⁇ bicyclic tetrapeptide isolated from Chrombacterium violaceum ⁇ broth medium.
  • FK228 has a unique bicyclic structure consisting of 4 amino acid residues (L-Val, L-2-amino-2-butylenoic acid, D-Cys, D-Val) and (3S, 4R-3-hydroxy-7- Mercapto -4- heptenoic acid) forms a bicyclic lactone structure through a disulfide bond. Its selectivity for HDAC1 and HDAC2 is similar. Computer simulations show that the thiol group of FK228 can bind to Zn 2+ through a water molecule.

Description

组蛋白去乙酰化酶抑制剂及其合成方法和制药用途 技术领域
本发明属于药物化学领域, 具体地涉及一类组蛋白去乙酰化酶抑制剂, 以及这些化合物 的合成方法和制药用途。
背景技术
组蛋白去乙酰化酶 (HDACs)是一组在细胞染色质水平、 通过诱导组蛋白去乙酰化来 调控包括染色质重组、 转录活化或抑制、 细胞周期、 细胞分化及细胞凋亡等一系列生物 学效应的酶, 特别是与细胞活化后的基因转录表达调控有关。 组蛋白去乙酰化酶抑制剂 (HDAC inhibitor, HDACIs)则是一类抑制 HDACs活性的化合物。
组蛋白乙酰化作用在染色体的 DNA转录, 复制和修复过程中起着非常重要的作用。 组 蛋白去乙酰化酶抑制剂过去一直作为情绪稳定剂和抗癫痫药物使用, 近年来, 人们开始关注 组蛋白去乙酰化酶抑制剂在神经变性疾病的靶向治疗作用。 染色质的组蛋白乙酰化和去乙酰 化是调节基因表达的关键环节之一, 而异常的基因表达是肿瘤及一些遗传和代谢疾病发生的 分子生物学基础。 组蛋白的乙酰化程度, 有组蛋白乙酰化酶 (HAT) 和组蛋白去乙酰化酶 (HDAC) 协调控制的。 实验证明, HDAC抑制剂会使染色质组蛋白乙酰化水平提高, 因此 导致特定基因激活表达, 相应的导致细胞的末端分化或癌细胞的凋亡。 因此, HDAC已成为 目前肿瘤化疗药物研发领域最热门的靶标之一。
目前已知组蛋白去乙酰化酶有 18个不同的亚型, 按种系分为 4大类: I ( HDAC1、 2、 3、 8 )、 II (HDAC4、 5、 6、 7、 9、 10)、 ( SIRT1-SIRT7 )和 IV( HDAC11)。 其中 I、 II、 IV为经典家族, 是 Zn2+依赖性的 HDAC。 目前临床研究的绝大多数 HDAC抑制剂能够抑制 HDAC 的多个亚型, 这些亚型往往属于 Zn2+依赖性的 HDAC家族。
组蛋白去乙酰化酶抑制剂可以抑制细胞内 HDAC 的活性,使细胞内组蛋白的乙酰化程度 增加, 提高 P2J、 p53 等基因的表达, 进而抑制肿瘤细胞的增殖, 诱导其分化、 凋亡。 组蛋 白去乙酰化酶抑制剂一般包括锌离子结合区, 连接区和表面识别区三个部分。 抑制剂与锌离 子的直接作用是产生抑制活性所必须的。 HDAC抑制剂主要包括以下四类: (1 )短链脂肪酸, 如丁酸, 苯丁酸及其盐类化合物; (2)羟肟酸类, 这是迄今研究最广泛的一类 HDAC抑制剂, 如辛二酰苯胺异羟肟酸(suberoylanilide hydroxamic acid SAHA)和曲古抑菌素 A (trichostatin A, TSA); ( 3 ) 环四肽类, 环肽类化合物是结构最为复杂的一类抑制剂, 环肽类抑制剂的分 子中氨基酸大环作为疏水的表面识别区, 烷基链作为连接区, 烷基链末端连接着一个锌离子 结合基团, 如 trapoxin, HC-toxon, Apicidin, FK228和 Largazole等; (4)苯甲酰胺类化合物, 这类化合物的活性比一般的羟肟酸类和环肽类化合物低, 但是对 I类 HDAC具有较高的选择 性。 如 MS-275, CI-994等。 2006年, 美国 FDA批准默克公司的辛二酰苯胺异羟肟酸
( suberoylanilide hydroxamic acid SAHA) 以 vorinostat (Zolinza) 上市, 用于治疗转移性皮 肤 T细胞淋巴瘤 (CTCL), 这是第一个面世的组蛋白去乙酰化酶抑制剂类抗肿瘤药物。
FK228(romidepsin)^从紫色杆菌 (Chrombacterium violaceum)^肉汤培养基中分离得到的 双环四肽。 FK228具有一个独特的双环结构, 由 4个氨基酸残基 (L-Val, L-2-amino-2-butylenoic acid, D-Cys, D-Val)和 (3S,4R-3-hydroxy-7-mercapto -4- heptenoic acid)通过二硫键形成双环内 酯结构。 其对 HDAC1和 HDAC2的选择性相似。 计算机模拟的结果表明, FK228的硫醇基团可 以通过一个水分子与 Zn2+结合。 美国 FDA于 2009年 11月 6日批准环肽 FK228以注射用药物 Istodax (romidepsin) 上市, 也于治疗皮肤 T淋巴细胞瘤 (CTCL), 成为继 Zolinza 后, 第二 个上市的组蛋白去乙酰化酶抑制剂, 其针对慢性淋巴细胞白血病、 急性髓样白血病和其他实 体瘤的研究正处于临床阶段。
由于与组蛋白去乙酰化酶调节异常相关的疾病特别是相关的癌症的发病率高、 预后差, 并且现有的药物的疗效不确切、 毒副作用较大, 因此需要一种新的低毒高效的组蛋白去乙酰 化酶抑制药物, 本发明因此而来。

实施例 98 HDAC生化活性的测定
1. 测定原理: 化合物生化活的性测定是根据其抑制 HDAC酶的去乙酰化作用程度来确定的。 用荧光标记的含有乙酰化的赖氨酸侧链的底物和 HDAC酶作用之后,该荧光底物被去乙酰化。 去乙酰化后的荧光标记底物被酶裂解后, 释放出荧光物质, 该荧光物质在 360nm光的激发下 产生 460nm的发射光。
2. 具体步骤: HDAC的底物用反应缓冲液稀释至 200M (反应浓度为 20M), 将 HDAC酶 稀释至适当浓度, 加入不同浓度待测化合物, 37°C反应 30分钟, 然后加入相同体积的 2倍浓 度底物发展液 (developer),室温孵育 15分钟,最后用微孔板读板仪测定读数,激发光为 360nm, 发射光为 460nm, 数据用 Prime 4软件处理。 市售 Zolinza ( SAHA) 作为对照。
