Description
技术领域
本发明涉及新型5-元杂环衍生物、互变异构体、药理学可接受的盐、前药或它们的药物用途。
背景技术
分子伴侣(molecular chaperones)为用于与服务蛋白(client protein)临时形成复合物以促进服务蛋白结构形成的蛋白质的通用术语。具有帮助蛋白的折叠和缔合(association)的以及防止聚集的活性的这些蛋白质广泛定义为分子伴侣。
将细胞暴露于多种环境应力,包括热休克、醇、重金属和氧化应力,导致大量伴侣的细胞累积,通常称为热休克蛋白(HSPs)。“热休克蛋白”家族(HSPs)的分子伴侣根据它们的分子质量进行分类(HSP70、HSP90、HSP27等),保护细胞免受初始应力损伤,增强恢复并导致保持应力耐受状态。然而,还清楚的是,通过调节重要的细胞蛋白质的正确的折叠、降解、定位和越来越多的功能,某些HSPs在正常的无应力条件下也可起到重要的分子伴侣的作用。
由于蛋白错误折叠,可使人类患有若干疾病。在一些状况下(例如,阿尔茨海默病、普利朊病和亨廷顿病),错误折叠的蛋白质可引起蛋白聚集,导致神经变性病症([Tytell M.和Hooper P.L.,Emerging Ther.Targets(2001),5,3788-3796])。HSPs,特别是HSP90,也涉及肿瘤细胞的各种主要功能的调节,经由它们与涉及细胞增殖或凋亡的各种服务蛋白的缔合。在这些病理学中,目的是破坏或扰乱伴侣的功能的方法可用于治疗疾病。尤其是,近来已证实HSP90伴侣在抗癌治疗中作为特别有希望的标靶([Moloney A.和Workman P.,Expert Opin.Biol.Ther.(2002),2(1),3-24];[Choisis等人,DrugDiscovery Today(2004),9,881-888])。
HSP90(热休克蛋白90)家族蛋白质包括HSP90α、HSP90β、GRP94和HSP75/TRAP1。这些蛋白质代表总细胞蛋白质量的约1-2%。其在细胞中通常为二聚体形式,并且与多种蛋白质缔合,所谓的共伴侣。通过与其天然的折叠被外部应力(例如,热休克)改变的许多蛋白质相互作用,HSP90在细胞应力的响应中起到关键的作用,以恢复初始折叠或防止蛋白质聚集([SmithD.F.等人,Pharmacological Rev.(1998),50,493-513])。假定通过校正由于变异引起的不正确的蛋白折叠,还存在迹象表明HSP90作为缓冲对抗变异作用的重要性([Rutherford和Lindquist,1998])。HSP90还具有调节重要性。在生理条件下,HSP90及其在内质网(endoplasmatic reticulum)中的同系物GRP94一起在细胞平衡中起作用,用于确保构造的稳定性和各种服务关键蛋白(client key protein)(例如,EGFR R/HER2、Src、Akt、Raf、MEK、Bcr-Abl、Flt-3、变异的p53、Akt、survivin、Cdk4、Plk、Wee1、VEGF-R、FAK、HIF-1、hTert和c-Met等)的成熟。这些服务蛋白涉及肿瘤发展的六种机理。i)在不存在生长因子(EGFR-R/HER2、Src、Akt、Raf、MEK、Bcr-Abl、Flt-3等)的条件下能够增殖;ii)能够逃避凋亡(p53、Akt、survivin等的变异的形式);iii)对增殖停止信号(Cdk4、Plk、Wee1等)的不敏感性;iv)能够激活血管生成(VEGF-R、FAK、HIF-1、Akt等);v)能够增殖,没有复制限制(hTert等);vi)能够逃避新的组织和转移(c-Met);(Hanahan D.和Weinberg R.A.,Cell(2002),100,57-70)。因此,通过抑制HSP90活性,可抑制服务蛋白-诱导的肿瘤形成。
首先已知的HSP90抑制剂为安莎霉素(ansamycin)家族的化合物,特别是格尔德霉素(geldanamycin)和除莠霉素(herbimycin)A。X-射线研究显示格尔德霉素与HSP90的N-末端区域的ATP部位结合,其抑制伴侣的ATPase活性(Prodromou C.等人,Cell(1997),90,65-75)。目前,NIH和KosanBioScience正进行17AAG(其为格尔德霉素-衍生的HSP90抑制剂)的临床发展。
根赤壳菌素也是天然来源的Hsp90抑制剂([Roe S.M.等人,J.MedChem.(1999),42,260-66])。然而,虽然迄今为止后者为最好的体外Hsp90抑制剂,但是关于含硫亲核试剂的其代谢不稳定性使其难以体内使用。一种天然来源的Hsp90抑制剂(新生霉素(novobiocin))与位于蛋白的C-末端区域的不同的ATP部位结合([Itoh H.等人,Biochem J.(1999),343,697-703])。已描述嘌呤例如化合物PU3([Chiosis等人,Chem.Biol.(2001),8,289-299])作为小分子Hsp90抑制剂。
此外,已描述类似物作为可用于治疗肿瘤的HSP90抑制剂,例如8-杂芳基-6-苯基咪唑并[1,2-a]吡嗪(WO 2004/072080)、吡唑衍生物(WO2004/050087)、异恶唑衍生物(WO 2004/07051)和二苯甲酮衍生物(WO2005/00778)。
已知的HSP90抑制剂涉及在位于蛋白的N-末端区域的ATP结合部位与HSP90结合,导致抑制HSP90的固有的ATPase活性。抑制HSP90ATPase活性防止共伴侣复原,靶向这些服务蛋白用于经由泛素蛋白酶体途径(ubiquitin proteasome pathway)降解。用于开发用于临床的对抗该靶向的药物的有吸引力的基本原理是通过同时耗尽肿瘤并与服务蛋白缔合,人们可得到强的抗肿瘤效果,并且实现相对于正常细胞,对抗癌症的治疗益处。

<实验1>体外测试抗肿瘤活性
对于本发明,使用孔雀绿检测测量酵母HSP90的ATPase活性。在人结肠直肠癌细胞(HCT116)中治疗式I化合物的主要抗肿瘤活性,显示HSP90服务蛋白的提高的表达水平,并测量共毒性IC50值作为结果。
表1
[表1]
体外测试抗肿瘤活性
IC50结果分配于以下3个范围之一:
范围A:IC50<500nM
范围B:IC50500nM~IC501000nM
范围C:IC50>1000nM
由表1可见,本发明的大多数化合物对于ATPase抑制活性和生长抑制检测呈现显著的抗肿瘤活性。
<实验2>体内测试抗肿瘤活性
为了评价体内抗肿瘤效力,如下测定本发明化合物(实施例60)。
通过向成年雌性Balb/c裸小鼠的肋中注射8×106个细胞,建立A2780人卵巢癌细胞作为皮下异种移植物。选择具有建立的肿瘤(50-200mm3)的小鼠用于研究(n=3~6/处理组)。将测试化合物在乙醇-PEG400-DW中配制,并且以200mg/kg的剂量口服给药(po)。对照组仅给药介质。将动物每周服药5天(周一至周五),保持连续2周。
将动物称重,通过卡尺测量每周两次测定肿瘤尺寸,计算肿瘤体积(体积=[l×w2]/2(mm3),其中l和w是指在每次测量时收集的较大和较小的尺寸)。计算每组的平均肿瘤体积。平均处理肿瘤体积的变化除以平均对照肿瘤体积的变化乘以100,再从100%减去,得到每组的肿瘤生长抑制。
表2
[表2]
化合物 | 剂量(mg/kg) | 方案 | %TGI |
实施例60(I-60) | 200 | po qdx5 | 50 |
所选化合物的肿瘤生长抑制描述于表2。所选的化合物显示显著的肿瘤生长抑制。那些化合物良好耐受,在这些剂量下显示没有与处理相关的毒性。
根据实验1和2,式I的新型化合物可用于抗肿瘤剂。
<实验3>小鼠药代动力学
进行药代动力学测试以证实本发明的前药到母体化合物的体内变化。通过口服管饲法使Balb/c雄性小鼠服用前药。假定单一给药前药,并且PO剂量的剂量体积为10mL/kg。
在10、20、30、60、120分钟时,在锂肝素涂布的管中收集血液样品。通过离心分离血浆并在分析前冷冻。
通过使用含有内标的乙酸乙酯液-液萃取,制备血浆样品。使用对于所选化合物特定的LC-MS/MS方法进行定量。分析服用所选化合物的动物的前药和母体化合物。使用WinNonLinnon间隔分析软件计算药代动力学参数。
表3
[表3]
在PO给药前药后的血浆AUC0-120分钟描述于表3。对于实施例113(II-8),采用100mg/kg的单一剂量测定血浆AUC0-120分钟。因此,实施例113(II-8)得到相对于起始剂量最优暴露的活性药物试剂(实施例97,I-97)。
因此,为式I的前药的式II化合物可用于抗肿瘤剂。
