Definitions
- the present invention relates to a pyrrolamide compound, a preparation method and use thereof, and particularly to a pyrrolamide compound having histone deacetylase inhibitory activity, a preparation method thereof and use thereof.
- Inactivation of genes that control cell growth in the body is a hallmark of tumorigenesis.
- the epigenetic mechanisms that cause gene inactivation mainly include DNA methylation, histone acetylation, and modification of other components in the chromatin high-level structure. These modifications alter the chromatin configuration, leading to changes in gene transcriptional regulation, and dysregulation of gene transcription. Cell proliferation is abnormal, resulting in tumor production.
- the more important acetylation site is H3. Lys 9 and Lys 14 , and Lys 5 , Lys 8 , Lys 12 and Lys 16 on H4.
- the acetylation of HAT causes the amino group of the N-terminal lysine of the histone to be acetylated, and the positive charge on the amino group is eliminated.
- the negative charge carried by the DNA molecule itself facilitates the unfolding of the DNA conformation, and the structure of the nucleosome becomes slack. Conducive to the contact of transcription factors and co-transcriptional activators with DNA molecules, histone acetylation can activate the transcriptional expression of specific genes.
- histone deacetylation is not conducive to the expression of specific genes (eg, Rb, p21, p27).
- the acetylation and deacetylation of histones becomes a switch for specific gene expression (Thiagalingam S, Cheng KH, Lee HJ, et al. Histone deacetylases: unique players in shaping the epigenetic histone code [J]. Ann NY Acad Sci, 2003, 983:84-100).
- Histone acetylation is regulated by a pair of functionally antagonistic protease histone acetyltransferases (HATs) and histone deacetylases (HDACs). In normal cells, this pair of enzymes is in a state of dynamic equilibrium. In general, increased levels of histone acetylation are associated with increased transcriptional activity, while low levels of acetylation are associated with inhibition of gene expression (Forsberg EC, Bresnick EH. Histone acetylation beyond promoters: long-range acetylation patterns in the chromatin world [ J]. Bioessays, 2001, 23(9): 820-830).
- HATs histone acetyltransferases
- HDACs histone deacetylases
- HDAC histone deacetylase inhibitors
- HDAC inhibitors inhibit HDAC enzyme activity by inhibiting HDAC, blocking gene expression inhibition due to HDAC recruitment dysfunction, and altering staining by altering the degree of histone acetylation Quality structure, which regulates gene expression to treat cancer. It is effective in treating hematological tumors and solid tumors by inducing growth arrest, differentiation or apoptosis of tumor cells. HDAC inhibitors are tumor-specific and have cytotoxic effects on both proliferating and resting variant cells, whereas normal cells are more than 10 times more tolerant and do not cause normal cell growth arrest and apoptosis. Moreover, the clinical dose of HDAC inhibitors is much lower than the maximum tolerated dose of the human body, and the toxicity to the body is low. The development and utilization of HDAC inhibitors has become a new hot spot in cancer therapy.
- HDAC inhibitors that have been researched and developed can be divided into five categories: (1) hydroxamic acid compounds, functional groups are hydroxamic acid, and representatives are TSA, SAHA (Curtin ML, Garland RB, Heyman HR, et A1.Succinimide hydroxamic acids as potent inhibitors of histone deacetylase [J]. Bioorg Med Chem Lett, 2002, 12(20): 2919-2923), LAQ824 (Atadja P, Hsu M, Kwon P, et a1.

Description
本发明涉及一种吡咯酰胺类化合物及其制备方法与用途,具体涉及一种具有组蛋白去乙酰化酶抑制活性的吡咯酰胺类化合物及其制备方法与用途。
在机体中控制细胞生长的基因失活是肿瘤发生的一个标志。引起基因失活的外遗传机制主要包括DNA甲基化,组蛋白乙酰化和染色质高级结构中其他成分的修饰,这些修饰改变染色质构型,导致基因转录调节发生变化,基因转录的失调引起细胞增殖失常,从而导致肿瘤产生。
40多年前,Allfrey等就认识到组蛋白的乙酰化过程和真核细胞基因转录调控密切相关(Allfrey VG,Faulkner R,Mirsky AE.Acetylation and methylation of histones and their possible role in the regulation of RNA synthesis[J].Proc Natl Acad Sci USA,1964,51:786-794)。组蛋白乙酰化对于真核细胞的转录调控起核心作用。组蛋白的乙酰化修饰发生在N-端进化保守的赖氨酸残基的ε-氨基上,在H3和H4上的修饰较H2A和H2B更为普遍,比较重要的乙酰化位点是H3上的Lys9和Lys14,以及H4上的Lys5,Lys8,Lys12及Lys16。HAT的乙酰化作用使组蛋白N端赖氨酸的氨基乙酰化,氨基上的正电荷被消除,DNA分子本身所带有的负电荷利于DNA构象的展开,核小体的结构变得松弛,有利于转录因子和协同转录活化子与DNA分子的接触,组蛋白乙酰化可以激活特定基因转录表达。相反的,组蛋白的去乙酰化作用不利于特定基因(如:Rb,p21,p27)的表达。组蛋白的乙酰化和去乙酰化成为特定基因表达的切换开关(Thiagalingam S,Cheng KH,Lee HJ,et al.Histonedeacetylases:unique players in shaping the epigenetic histone code[J].Ann N Y Acad Sci,2003,983:84-100)。
组蛋白乙酰化作用受一对功能相互拮抗的蛋白酶组蛋白乙酰化转移酶(HATs)和组蛋白去乙酰化酶(HDACs)调控。在正常细胞中,这一对酶处于动态平衡状态。一般情况下,组蛋白乙酰化水平增强与基因转录活性增强有关,而乙酰化水平过低与基因表达抑制有关(Forsberg EC,Bresnick EH.Histone acetylation beyond promoters:long-range acetylation patterns in the chromatin world[J].Bioessays,2001,23(9):820-830)。研究发现,HDAC过度表达并被转录因子募集,导致特定基因的不正常抑制,从而导致肿瘤和其他疾病;而抑制HDAC的活性将引起许多癌细胞的生长抑制和凋亡(Somech R,Izraeli S,J Simon A.Histone deacetylase inhibitors-a new tool to treat cancer[J].Cancer Treat Rev,2004,30(5):461-472)。因此,HDAC已成为目前抗肿瘤药物研发领域最新和最热门的靶标。
HDAC抑制剂,可抑制HDAC酶活性,其作用机制是通过抑制HDAC,阻断由于HDAC募集功能紊乱而导致的基因表达受抑,通过改变组蛋白的乙酰化程度来改变染色
质结构,从而调控基因表达治疗癌症。它通过诱导肿瘤细胞的生长停滞、分化或凋亡对治疗血液系统肿瘤和实体瘤疗效显著。HDAC抑制剂具有肿瘤特异性,对增殖和静止的变异细胞均有细胞毒作用,而正常细胞对它有10倍以上的耐受,不会引起正常细胞的生长停滞和凋亡。而且HDAC抑制剂临床用量远低于人体最大耐受量,对机体的毒性较低。HDAC抑制剂的开发利用已成为肿瘤治疗的一个新热点。
目前,已经研究开发的HDAC抑制剂可分为五大类:(1)异羟肟酸类化合物,功能基团为羟肟酸,代表物有TSA、SAHA(Curtin ML,Garland RB,Heyman HR,et a1.Succinimide hydroxamic acids as potent inhibitors of histone deacetylase[J].Bioorg Med Chem Lett,2002,12(20):2919-2923),LAQ824(Atadja P,Hsu M,Kwon P,et a1.Moleculer and cellular basis for the anti-proliferative effects of the HDAC inhibitor LAQ824.Novartis Found Symp,2004,259:249-266);(2)含2-氨基-8-氧-9,10-环氧癸酰基或不含有该基团的环四肽,如FK-228;(3)苯甲酰胺类化合物,代表物MS-275已进入临床研究;(4)短链脂肪酸类,如丁酸和苯丁酸;(5)其他类,该类HDAC抑制剂不具有一般HDAC的结构特征,但都含有抑制HDAC活性要求的一些或全部的结构亚单位。
例如,中国专利CN 103420917 A公开了一种含稠环结构的苯甲酰胺类化合物,如式A所示,对组蛋白去乙酰化酶抑制活性及在治疗恶性肿瘤及与分化和增殖相关疾病方面的应用;中国专利CN 103288728 A公开了一种萘甲酰胺衍生物,如式B所示,能够有效治疗蛋白激酶调节异常所引发的部分疾病;中国专利CN 103539695 A公开了一种取代二苯醚类组蛋白去乙酰化酶抑制剂,如式C所示;中国专利CN 103467359 A公开了一种含有吲哚的肉桂酰胺类组蛋白去乙酰化酶抑制剂,如式D所示;中国专利CN 102659630 A公开了异羟肟酸类化合物,如式E所示。
中国专利CN 102786458 A公开了一种吡咯甲酰胺衍生物,如式F所示,作为抗恶性肿瘤药物方面的应用,特别是在用于制备治疗乳腺癌、肺癌、胃癌药物方面的用途。
R1,R2,R3,R4为:C1-C6直链或支链烷基,C3-C6环烷基;
R5,R6同时或分别为:氢,C1-C6烷基;羟基,卤素,C1-C4烷氧基,硝酸酯基取代的C1-C6的烷基。
目前,Merck公司研制的SAHA,是已经上市的组蛋白去乙酰化酶抑制剂,仅局限于对皮肤T细胞淋巴癌的治疗,对其他很多癌症的疗效并不明显。其他研发的HDAC抑制剂,在抗癌活性、毒副作用、亚型选择性等方面也存在一定的问题。因此,开发一种具有组蛋白去乙酰化酶抑制活性的新化合物具有十分重要的社会和经济意义。
