Description

组蛋白脱乙酰化酶抑制剂
相关申请的交叉参考
本申请是美国申请10/242,304的部分继续申请。
技术领域
本发明涉及抑制组蛋白脱乙酰化酶(deacetylase)。本发明更具体涉及抑制组蛋白脱乙酰化酶活性的化合物和方法。
背景技术
在真核细胞中,细胞核DNA与组蛋白结合以形成称为染色质的紧密复合物。组蛋白构成了在真核生物物种之间通常高度保守的碱性蛋白家族。称为H2A、H2B、H3和H4的核心组蛋白结合以形成蛋白核心。DNA沿着该蛋白核心缠绕,同时组蛋白的碱性氨基酸与DNA的带负电荷的磷酸根基团相互作用。约有146个DNA的碱基对沿着组蛋白核心缠绕,以构成核小体颗粒—染色质的重复结构基元。
Csordas,Biochem.J.,286:23-38(1990)提出,组蛋白发生N-末端赖氨酸残基的α,ε-氨基的翻译后乙酰化,这是被组蛋白乙酰转移酶(HAT1)催化的反应。乙酰化中和了赖氨酸侧链的正电荷,并且据信会影响染色质结构。Taunton等人,Science,272:408-411(1996)提出,转录因子到达染色质模板的路径被组蛋白高度乙酰化增强。Taunton等人还指出,在基因组的转录沉默区域中发现了富集的乙酰化组蛋白H4。
组蛋白乙酰化是可逆修饰,其中脱乙酰化是由称为组蛋白脱乙酰化酶(HDAC)的一族酶催化的。Grozinger等人,Proc.Natl.Acad.Sci.USA,96:4868-4873(1999)中提出HDAC分为两类,第一类由酵母Rpd3-样蛋白代表,第二类由酵母Hda1-样蛋白代表。Grozinger等人还提出,人HDAC1、HDAC2和HDAC3蛋白是第一类HDAC的成员,并且公开了称为HDAC4、HDAC5和HDAC6的新蛋白,它们是第二类HDAC的成员。Kao等人,Genes & Dev.,14:55-66(2000)公开了HDAC7-第二类HDAC的一个新成员。Van den Wyngaert,FEBS,478:77-83(2000)公开了HDAC8第一类HDAC的一个新成员。
Richon等人,Proc.Natl.Acad.Sci.USA,95:3003-3007(1998)公开了HDAC活性被曲古抑菌素A(TSA)—一种从吸水链霉菌(Streptomyces hygroscopicus)中分离的天然产物和合成化合物辛二酰苯胺异羟肟酸(SAHA)抑制。Yoshida和Beppu,Exper.Cell Res.,177:122-131(1988)指出,TSA在细胞周期的G1和G2期引起大鼠成纤维细胞的停滞,这意味着HDAC在细胞周期中具有调控作用。Finnin等人,Nature,401:188-193(1999)提出,TSA和SAHA抑制细胞生长,诱导末端分化,并防止在小鼠中形成肿瘤。Suzuki等人,U.S.专利6,174,905、EP 0847992、JP 258863/96和第10138957号日本专利申请公开了诱导细胞分化和抑制HDAC的苯甲酰胺衍生物。Delorme等人,WO01/38322和PCT IB01/00683公开了起HDAC抑制剂作用的另外一些化合物。
编码具有HDAC活性的蛋白的基因序列的分子克隆已确立了存在一组离散的HDAC酶同种型。Grozinger等人,Proc.Natl.Acad.Sci.USA,96:4868-4873(1999)中提出HDAC分为两类,第一类由酵母Rpd3-样蛋白代表,第二类由酵母Hda1-样蛋白代表。Grozinger等人还提出,人HDAC1、HDAC2和HDAC3蛋白是第一类HDAC的成员,并且公开了称为HDAC4、HDAC5和HDAC6的新蛋白,它们是第二类HDAC的成员。Kao等人,Gene & Development,14:55-66(2000)公开了称为HDAC-7的第二类的另一个成员。最近,Hu,E.等人.J.Bio.Chem.275:15254-13264(2000)公开了第一类组蛋白脱乙酰化酶的一个最新成员HDAC-8。尚不清楚这些HDAC酶起什么作用。
这些发现表明,抑制HDAC活性是干预细胞周期调控的一种新方法,并且HDAC抑制剂在细胞增殖性疾病或病症的治疗中有着很大的治疗潜力。迄今为止,本领域中已知的组蛋白脱乙酰化酶抑制剂很少。因此需要确定出另外的HDAC抑制剂和确定出有效HDAC抑制活性所需的结构特征。

优选实施方案的详细描述
本发明提供了抑制组蛋白脱乙酰化酶活性的化合物和方法。本发明还提供了用于治疗细胞增殖性疾病和病症的组合物和方法。本文中引用的专利和科学文献建立了本领域技术人员可以获得的知识。在本文中引用的公布的专利、申请和参考文献以同样的程度在此引入作为参考,即每个特定且单独在此引入作为参考。当不一致时,本申请公开内容将占优势。
对于本发明目的,使用下列定义(除非另有说明):
本文所用术语“组蛋白脱乙酰化酶”和“HDAC”是指能将乙酰基从在组蛋白的N-末端的赖氨酸残基的α,ε-氨基上除去的酶家族的任一个成员。除非在上下文中另有说明,术语“组蛋白”是指得自任何物种的任何组蛋白,包括H1、H2A、H2B、H3、H4和H5。优选的组蛋白脱乙酰化酶包括I类和II类酶。组蛋白脱乙酰化酶优选为人HDAC,包括但不限于HDAC-1、HDAC-2、HDAC-3、HDAC-4、HDAC-5、HDAC-6、HDAC-7和HDAC-8。在某些其它优选的实施方案中,组蛋白脱乙酰化酶得自原生动物或真菌来源。
术语“组蛋白脱乙酰化酶抑制剂”和“组蛋白脱乙酰化酶的抑制剂”是指具有本文所定义结构的化合物,其能够与组蛋白脱乙酰化酶相互作用并且抑制组蛋白脱乙酰化酶的酶活性。“抑制组蛋白脱乙酰化酶活性”是指降低组蛋白脱乙酰化酶将乙酰基从组蛋白上除去的能力。在某些优选的实施方案中,组蛋白脱乙酰化酶活性被降低了至少约50%,更优选至少约75%,还更优选至少约90%。在其它优选的实施方案中,组蛋白脱乙酰化酶活性被降低了至少95%,更优选至少99%。

载体的特征取决于给药途径。本文所用术语“可药用”是指这样的无毒材料,其与生物系统例如细胞、细胞培养物、组织或生物体相容,并且不干扰活性组分的生物活性的有效性。因此,除了本发明抑制剂以外,本发明组合物还包含稀释剂、填充剂、盐、缓冲剂、稳定剂、助溶剂和本领域众所周知的其它材料。可药用制剂的制备描述在例如Remington’s Pharmaceutical Sciences,18th Edition,ed.A.Gennaro,Mack Publishing Co.,Easton,PA,1990中。
本文所用术语可药用盐是指保持上述化合物希望的生物活性,并且表现出最小或没有任何不良毒性作用的盐。这样的盐的实例包括但不限于与下列酸形成的酸加成盐:无机酸(例如盐酸、氢溴酸、硫酸、磷酸、硝酸等),和有机酸例如乙酸、草酸、酒石酸、琥珀酸、苹果酸、抗坏血酸、苯甲酸、鞣酸、扑酸、藻酸、聚谷氨酸、萘磺酸、萘二磺酸和聚半乳糖醛酸。化合物还可以作为本领域技术人员已知的可药用季铵盐给药,这样的季铵盐具体包括式-NR+Z-的铵盐,其中R是氢、烷基或苄基,且Z是抗衡离子,包括氯离子、溴离子、碘离子、-O-烷基、甲苯磺酸基、甲磺酸基、磺酸基、磷酸根或羧酸基(例如苯甲酸基、琥珀酸基、乙酸基、羟乙酸基、马来酸基、苹果酸基、柠檬酸基、酒石酸基、抗坏血酸基、苯甲酸基、肉桂酸基、扁桃酸基、苯甲醇阴离子和二苯基乙酸基)。
活性化合物以足以给患者递送治疗有效量,同时在所治疗的患者中不引起严重毒性作用的量包含在可药用载体或稀释剂中。对于所有上述病症,活性化合物的优选剂量为约0.01-300mg/kg,优选为0.1-100mg/kg每天,更通常为0.5-约25mg/千克接受者的体重/天。典型的局部给药剂量为在适当载体中的0.01-3%wt/wt。本发明可药用衍生物的有效剂量可根据欲给药的母化合物的重量计算。如果衍生物自身表现出活性,则可以用衍生物的重量如上所述估计有效剂量或者通过本领域技术人员已知的其它方法估计有效剂量。
                 抑制组蛋白脱乙酰化酶
在第三个方面,本发明提供了抑制细胞中组蛋白脱乙酰化酶的方法,包括将希望抑制其组蛋白脱乙酰化酶的细胞与本发明组蛋白脱乙酰化酶抑制剂接触。因为本发明化合物能抑制组蛋白脱乙酰化酶,所以它们是用于在体外研究生物过程中组蛋白脱乙酰化酶的作用的有用研究工具。此外,本发明化合物可选择性地抑制HDAC的一些异构体。
可使用已知方法测定组蛋白脱乙酰化酶的酶活性。例如Yoshida等人,J.Biol.Chem.,265:17174-17179(1990)描述了通过检测曲古柳菌素(trichostatin A)处理的细胞中的乙酰化组蛋白来评价组蛋白脱乙酰化酶的酶活性。Taunton等人,Science,272:408-411(1996)类似地描述了通过使用内源性和重组HDAC-1来测定组蛋白脱乙酰化酶的酶活性的方法。
在某些优选实施方案中,组蛋白脱乙酰化酶抑制剂与细胞中的所有组蛋白脱乙酰化酶相互作用并降低它们的活性。在依据本发明该方面的某些其它优选实施方案中,组蛋白脱乙酰化酶抑制剂与细胞中少数组蛋白脱乙酰化酶而不是所有组蛋白脱乙酰化酶相互作用,并降低它们的活性。在一些优选的实施方案中,抑制剂与一种组蛋白脱乙酰化酶(例如HDAC-1)反应并降低其活性,而不与其它组蛋白脱乙酰化酶(例如HDAC-2、HDAC-3、HDAC-4、HDAC-5、HDAC-6、HDAC-7和HDAC-8)相互作用或降低它们的活性。如下所述,一些特别优选的组蛋白脱乙酰化酶抑制剂是与涉及肿瘤发生的组蛋白脱乙酰化酶相互作用并降低其酶活性的那些。一些其它优选的组蛋白脱乙酰化酶抑制剂与真菌组蛋白脱乙酰化酶相互作用并降低其酶活性。
优选地,依据本发明第三个方面的方法引起所接触的细胞的细胞增殖被抑制。短语“抑制细胞增殖”是用来指,与未接触的细胞相比,组蛋白脱乙酰化酶抑制剂延迟与抑制剂接触的细胞生长的能力。细胞增殖的评价可通过使用Coulter细胞计数器(Coulter,Miami,FL)或血细胞计数器计数接触和未接触的细胞来进行。当细胞在实体生长(例如实体瘤或器官)中时,这样的细胞增殖评价可通过用卡钳测定生长,并比较接触的细胞与未接触的细胞的生长尺寸来进行。
优选地,与未接触的细胞相比,与抑制剂接触的细胞的生长被延迟了至少50%。更优选地,细胞增殖被抑制了100%(即接触的细胞在数目上没有任何增加)。更优选地,短语“抑制细胞增殖”包括,与未接触的细胞相比,接触的细胞的数目减少或尺寸减小。因此,本发明抑制细胞增殖的组蛋白脱乙酰化酶抑制剂可诱导接触的细胞经受生长延迟、经受生长停滞、经受编程性细胞死亡(即细胞凋亡)或经受坏死性细胞生长。
本发明组蛋白脱乙酰化酶抑制剂的细胞增殖抑制能力使得不同步生长的细胞群体同步化。例如,本发明组蛋白脱乙酰化酶抑制剂可用于在体外抑制处于细胞周期的G1或G2期的非瘤形成细胞群体。这样的同步化使得能够例如鉴定在细胞周期的G1或G2期时段内表达的基因和/或基因产物。这样的培养细胞的同步化还可用于测试新转染方案的效力,其中转染效力随着欲转染的细胞的特定细胞周期时期而变并取决于特定细胞周期的时期。本发明组蛋白脱乙酰化酶抑制剂的应用使得细胞群体同步化,由此能够有助于检测提高的转染效力。
在某些优选实施方案中,接触的细胞是瘤形成细胞。术语“瘤形成细胞”是用来指表现出异常细胞生长的细胞。瘤形成细胞的异常细胞生长优选是增加的细胞生长。瘤形成细胞可以是增生细胞,在体外表现出缺乏生长接触抑制的细胞,在体内不能转移的良性肿瘤细胞,或在体内能够转移,并且在试图除去之后可复发的癌细胞。术语“肿瘤发生”是用来指导致肿瘤生长发展的细胞增殖诱导。在某些实施方案中,本发明组蛋白脱乙酰化酶抑制剂在接触的细胞中诱导细胞分化。因此,当与组蛋白脱乙酰化酶抑制剂接触时,瘤形成细胞可被诱导发生分化,导致产生在种系发生方面比接触的细胞更高级的非瘤形成子细胞。
在某些优选实施方案中,接触的细胞在动物中。因此,本发明提供了治疗动物中细胞增殖疾病或病症的方法,包括给需要这种治疗的动物施用治疗有效量的本发明组蛋白脱乙酰化酶抑制剂。动物优选为哺乳动物,更优选为驯养的哺乳动物。动物最优选为人。
术语“细胞增殖疾病或病症”是指特征是异常细胞生长,优选异常增加的细胞增殖的任何病症。这样的细胞增殖疾病或病症的实例包括但不限于癌症、再狭窄和牛皮癣。在特别优选的实施方案中,本发明提供了抑制动物中瘤形成细胞增殖的方法,包括给体内存在至少一种瘤形成细胞的动物施用治疗有效量的本发明组蛋白脱乙酰化酶抑制剂。
某些本发明化合物具有抗原生动物来源的组蛋白脱乙酰化酶的抑制活性。因此,本发明还提供了治疗或预防原生动物疾病或感染的方法,包括给需要这种治疗的动物施用治疗有效量的本发明组蛋白脱乙酰化酶抑制剂。动物优选为哺乳动物,更优选为人。优选地,依据本发明该实施方案使用的组蛋白脱乙酰化酶抑制剂抑制原生动物组蛋白脱乙酰化酶的程度大于其抑制哺乳动物组蛋白脱乙酰化酶,特别是人组蛋白脱乙酰化酶的程度。
本发明还提供了治疗真菌疾病或感染的方法,包括给需要这种治疗的动物施用治疗有效量的本发明组蛋白脱乙酰化酶抑制剂。动物优选为哺乳动物,更优选为人。优选地,依据本发明该实施方案使用的组蛋白脱乙酰化酶抑制剂抑制真菌组蛋白脱乙酰化酶的程度大于其抑制哺乳动物组蛋白脱乙酰化酶,特别是人组蛋白脱乙酰化酶的程度。
术语“治疗有效量”是指足以在个体的细胞中引起组蛋白脱乙酰化酶活性被抑制的剂量,或足以在个体中抑制细胞增殖或诱导细胞分化的剂量。给药可通过任何途径进行,包括但不限于非胃肠道、口服、舌下、透皮、局部、鼻内、气管内或直肠内给药途径。在一些特别优选的实施方案中,本发明化合物可在医院中静脉内给药。在一些其它优选的实施方案中,给药可优选通过口服途径进行。
当全身给药时,组蛋白脱乙酰化酶抑制剂优选以足以达到下列抑制剂血液水平的剂量给药:约0.01μM-约100μM,更优选约0.05μM-约50μM,还更优选约0.1μM-约25μM,仍更优选约0.5μM-约25μM。对于局部给药,比此低得多的浓度可能是有效的,并且可耐受高得多的浓度。本领域技术人员应当理解,产生疗效所需的组蛋白脱乙酰化酶抑制剂的剂量可根据欲治疗的组织、器官或特定动物或患者而显著改变。
在本发明第三个方面的一些优选实施方案中,方法包括将细胞与抑制组蛋白脱乙酰化酶表达的反义低聚核苷酸接触。核酸水平抑制剂(例如反义低聚核苷酸)与蛋白水平抑制剂(即组蛋白脱乙酰化酶的酶活性抑制剂)的联合使用带来了提高的抑制作用,由此降低了达到给定抑制作用所需的抑制剂的量—与单独使用任一种抑制剂所需的量相比。依据本发明该方面的反义低聚核苷酸与编码HDAC-1、HDAC-2、HDAC-3、HDAC-4、HDAC-5、HDAC-6、HDAC7和/或HDAC-8的RNA或双螺旋DNA区域互补(参见例如对于HDAC-1的GenBankAccession Number U50079,对于HDAC-2的GenBank AccessionNumber U31814,和对于HDAC-3的GenBank Accession NumberU75697)。
对于本发明目的,术语“低聚核苷酸”包括两个或多个脱氧核苷、核糖核苷或2’-取代的核糖核苷残基或其任何组合的聚合物。优选地,这样的低聚核苷酸具有约6-约100个核苷残基,更优选约8-约50个核苷残基,最优选约12-约30个核苷残基。核苷残基可通过任何多种已知的核苷间键彼此偶联。这样的核苷间键包括但不限于硫代磷酸酯、二硫代磷酸酯、烷基磷酸酯、烷基硫代膦酸酯、磷酸三酯、氨基磷酸酯、硅氧烷、碳酸酯、羧基甲基酯、乙酰胺酸酯、氨基甲酸酯、硫醚、桥连氨基磷酸酯、桥连膦酸亚甲基酯、桥连硫代磷酸酯和砜核苷间键。在一些优选的实施方案中,这些核苷间键可以是磷酸二酯、磷酸三酯、硫代磷酸酯或氨基磷酸酯键或其组合。术语低聚核苷酸还包括具有化学修饰的碱基或糖和/或具有另外的取代基,包括但不限于亲脂性基团、嵌入剂、二胺和金刚烷的聚合物。
对于本发明目的,术语“2’取代的核糖核苷”包括其中在戊糖部分的2’-位的羟基被取代以生成2’-O-取代的核糖核苷的核糖核苷。优选地,这样的取代是被下列基团取代:含有1-6个饱和或不饱和碳原子的低级烷基或具有2-6个碳原子的芳基或烯丙基,其中这样的烷基、芳基或烯丙基可以是未取代或取代的,例如被卤素、羟基、三氟甲基、氰基、硝基、酰基、酰氧基、烷氧基、羧基、烷氧羰基或氨基取代。术语“2’取代的核糖核苷”还包括其中2’-羟基被氨基或卤素,优选氟替代的核糖核苷。
在本发明该方面使用的特别优选的反义低聚核苷酸包括嵌合低聚核苷酸和杂合低聚核苷酸。
对于本发明目的,“嵌合低聚核苷酸”是指具有一种以上类型的核苷间键的低聚核苷酸。这样的嵌合低聚核苷酸的一个优选的实例是包含硫代磷酸酯、磷酸二酯或二硫代磷酸酯区域-优选包含约2-约12个核苷,和烷基磷酸酯或烷基硫代膦酸酯区域的嵌合低聚核苷酸(参见例如Pederson等人U.S.专利5,635,377和5,366,878)。优选地,这样的嵌合低聚核苷酸含有至少3个选自磷酸二酯和硫代磷酸酯键或其组合的连续的核苷间键。
对于本发明目的,“杂合低聚核苷酸”是指具有一种以上类型的核苷的低聚核苷酸。这样的杂合低聚核苷酸的一个优选实例包含核糖核苷酸或2’-取代的核糖核苷酸区域-优选包含约2-约12个2’-取代的核苷酸,和脱氧核糖核苷酸区域。优选地,这样的杂合低聚核苷酸包含至少3个连续的脱氧核糖核苷,并且还包含核糖核苷、2’-取代的核糖核苷,优选2’-O-取代的核糖核苷或其组合(参见例如Metelev和Agrawal,U.S.专利5,652,355)。
在本发明中使用的反义低聚核苷酸的精确核苷酸序列和化学结构可以变化,只要低聚核苷酸保持其抑制目标基因表达的能力即可。这可通过测试特定反义低聚核苷酸是否有活性来容易地确定。对于此目的,有用的测定包括定量测定编码基因产物的mRNA,基因产物的Western印迹分析测定,酶活性基因产物的活性测定,或软琼脂生长测定,或报道基因构建测定,或体内肿瘤生长测定,所有这些都详细描述在本说明书或Ramchandani等人(1997)Proc.Natl.Acad.Sci.USA 94:684-689中。
在本发明中使用的反义低聚核苷酸可在合适的固体载体上用众所周知的化学方法来常规合成,这些方法包括H-膦酸酯化学、氨基磷酸酯化学或H-膦酸酯化学与氨基磷酸酯化学的组合(即对于某些循环使用H-膦酸酯化学,对于其它循环使用氨基磷酸酯活性)。合适的固体载体包括用于固相低聚核苷酸合成的任何标准固体载体例如孔控玻璃(CPG)(参见例如Pon,R.T.(1993)Methods in Molec.Biol.20:465-496)。
特别优选的低聚核苷酸具有约13-约35个核苷酸的核苷酸序列,包括表1所示序列。还特别优选的低聚核苷酸具有表1所示的约15-约26个核苷酸的核苷酸序列。

某些小鼠既接受反义低聚核苷酸,也接受HDAC抑制剂。在这些小鼠中,一组可接受经由尾静脉同时静脉内给予的反义低聚核苷酸和HDAC抑制剂。另一组可接受经由尾静脉给予的反义低聚核苷酸和皮下给予的HDAC抑制剂。还有一组可接受都是皮下给予的反义低聚核苷酸和HDAC抑制剂。类似地建立对照组小鼠,它们不接受任何治疗(例如仅接受盐水),仅接受错配的反义低聚核苷酸,不抑制组蛋白脱乙酰化酶活性的对照化合物,和错配的反义核苷酸和对照化合物。
用卡钳测定肿瘤体积。与对照相比,用反义低聚核苷酸加上本发明组蛋白脱乙酰化酶蛋白抑制剂治疗使得肿瘤重量和体积显著减小。
