Description
本發明係關於一種調控Wnt訊號傳導路徑之組合物及方法。
本申請案主張2009年3月2日申請之美國臨時申請案第61/156,599號及2009年9月23日申請之美國臨時申請案第61/245,187號之權利,其各者皆以全文引用的方式併入本文中。
Wnt基因家族編碼一大類與Int1/Wnt1原致癌基因及果蠅無翅基因(「Wg」)(果蠅Wnt1同源基因)有關之分泌蛋白(Cadigan等人,(1997) Genes & Development 11:3286-3305)。Wnt表現於各種組織及器官中且在許多發育過程中具有重要作用,包括果蠅分節;線蟲(C. elegans)內胚層發育;及哺乳動物中確立四肢極性、神經脊分化、腎臟形態發生、性別確定及腦發育(Parr等人,(1994) Curr. Opinion Genetics & Devel. 4:523-528)。Wnt路徑為動物發育(胚胎發生期間與成熟有機體中)之主要調節器(Eastman等人,(1999) Curr Opin Cell Biol 11: 233-240;Peifer等人,(2000) Science 287: 1606-1609)。
Wnt訊號係由Frizzled(「Fz」)家族之七個跨膜域受體傳導(Bhanot等人,(1996) Nature 382:225-230)。Wnt配位體結合Fzd,且藉此活化細胞質蛋白質Dishevelled(人類及小鼠中之Dvl-1、2及3)(Boutros等人,(1999) Mech Dev 83:27-37)且使LRP5/6磷酸化。由此產生訊號防止犰狳蛋白(Armadillo)/β-索烴素之磷酸化及降解,又從而使β-索烴素穩定(Perrimon(1994) Cell 76:781-784)。該穩定由Dvl與軸蛋白(axin)結合所引起(Zeng等人,(1997) Cell 90:181-192),軸蛋白為一種支架蛋白,其使包括GSK3、APC、CK1及β-索烴素之各種蛋白質聚集在一起形成β-索烴素破壞複合物。
無翅型(Wnt)Frizzled蛋白受體路徑涉及攜有與原發癌相關之多形性的重要調節基因。在下游訊號傳導過程中,胞內β-索烴素積聚、移位至細胞核中,且隨後藉由與其他轉錄因子複合來增強基因表現(Uthoff等人,Mol Carcinog,
31:56-62(2001))。缺乏Wnt訊號時,游離胞內β-索烴素被併入由軸蛋白、腺瘤性息肉(APC)基因產物及肝糖合成酶激酶(GSK)-3β組成之複合物中。GSK-3β使軸蛋白、APC及β-索烴素發生結合性磷酸化可為β-索烴素指定泛素路徑且指定β-索烴素由蛋白酶體降解(Uthoff等人,Mol Carcinog,
31:56-62(2001);Matsuzawa等人,Mol Cell,
7:915-926(2001))。
Disheveled(Dvl)為位於frizzled受體下游及β-索烴素上游的Wnt訊號傳導正向介體。GSK-3使Wnt路徑中之若干蛋白質磷酸化且有助於β-索烴素之下游調節。APC基因突變為偶發性與遺傳性結腸直腸腫瘤形成之引發事件。APC突變體與腫瘤形成相關,因為該異常蛋白為Wnt訊號傳導級聯不可分割的部分。蛋白質產物含有若干充當β-索烴素結合位點及降解位點之功能域。發生於β-索烴素胺基端區段之突變通常與磷酸化依賴性、泛素介導之降解有關且因此使β-索烴素穩定。當穩定之細胞質索烴素積聚時,其移位至細胞核,與調控諸如c-myc之致癌基因表現的Tcf/Lef高遷移類轉錄因子相互作用。
已知Wnt/β-索烴素訊號傳導可提高各種細胞類型之細胞存活(Orford等人,J Cell Biol,
146:855-868(1999);Cox等人,Genetics,
155:1725-1740(2000);Reya等人,Immunity,
13:15-24(2000);Satoh等人,Nat Genet,
24:245-250(2000);Shin等人,Journal of Biological Chemistry,
274:2780-2785(1999);Chen等人,J Cell Biol,
152:87-96(2001);Ioannidis等人,Nat Immunol,
2:691-697(2001))。亦咸信Wnt訊號傳導路徑與腫瘤發展及/或進程相關(Polakis等人,Genes Dev,
14:1837-1851(2000);Cox等人,Genetics,
155:1725-1740(2000);Bienz等人,Cell,
103:311-320(2000);You等人,J Cell Biol,
157:429-440(2002))。Wnt訊號傳導路徑之異常活化與各種人類癌症相關,該等癌症與c-Myc過度表現或擴增有關(Polakis等人,Genes Dev,
14:1837-1851(2000);Bienz等人,Cell,
103:311-320(2000);Brown等人,Breast Cancer Res,
3:351-355(2001);He等人,Science,
281:1509-1512(1998);Miller等人,Oncogene,
18:7860-7872(1999))。此外,c-Myc經鑑定為結腸直腸癌細胞中β-索烴素/Tcf之轉錄靶之一(He等人,Science,
281:1509-1512(1998);de La Coste等人,Proc Natl Acad Sci USA,
95:8847-8851(1998);Miller等人,Oncogene,
18:7860-7872(1999);You等人,J Cell Biol,
157:429-440(2002))。
因此,需要調控Wnt訊號傳導路徑之藥劑及方法,藉此治療、診斷、預防及/或改善與Wnt訊號傳導相關之病症。
本發明係關於調控Wnt訊號傳導路徑之組合物及方法。

H及14
C同位素。在其他實例中,以諸如2
H之同位素取代可產生由較大代謝穩定性導致的特定治療優勢,諸如活體內半衰期延長或劑量需要量減少。本發明化合物或其醫藥學上可接受之鹽的同位素變體一般可藉由習知程序使用適合試劑的適當同位素變體製備。化合物之同位素變體可能會改變化合物代謝結果及/或使物理性質(諸如疏水性及其類似性質)發生微小改變。同位素變體可能會增強功效及安全性、增強生物可用性及半衰期、改變蛋白質結合、改變生物分布、增加活性代謝物比例及/或降低反應性或毒性代謝物形成。
本發明亦提供一種抑制細胞中Wnt訊號傳導之方法,其包含使細胞與有效量Wnt拮抗劑接觸。在一實施例中,細胞包含在哺乳動物中且投與量為治療有效量。在一實施例中,Wnt訊號傳導之抑制進一步導致細胞生長之抑制。在另一實施例中,細胞為癌細胞。
使用熟習此項技術者已知之方法量測細胞增殖之抑制。舉例而言,適用於量測細胞增殖之檢定為可購自Promega(Madison,Wis.)之CellTiter-GloTM
發光細胞存活率檢定。該檢定係根據定量存在之ATP(其為代謝活性細胞之指示)測定培養物中活細胞的數目。參見Crouch等人,(1993)J. Immunol. Meth.
160:81-88;美國專利第6,602,677號。該檢定可在96孔或384孔格式中進行,從而可達成自動高產量篩檢(HTS)。參見Cree等人,(1995)AntiCancer Drugs
6:398-404。該檢定程序涉及直接向培養細胞中添加單一試劑(CellTiter-Glo試劑)。由此引起細胞溶解且生成藉由螢光素酶反應產生之發光訊號。發光訊號與ATP存在之量成比例,而ATP存在之量與培養物中存在之活細胞數目成正比。可由光度計或CCD相機成像裝置來記錄數據。發光輸出係以相對光單位(RLU)表示。細胞增殖之抑制亦可使用此項技術中已知之群落形成檢定來量測。
此外,本發明提供治療哺乳動物所罹患之Wnt介導病症的方法,其包含向該哺乳動物投與治療有效量之Wnt拮抗劑。在一實施例中,該病症為與Wnt訊號傳導表現活性異常(例如增加)相關之細胞增殖病。在另一實施例中,該病症由Wnt蛋白質表現增加所引起。在又一實施例中,細胞增殖病為癌症,諸如結腸癌、結腸直腸癌、乳癌;與各種HSC相關性病症有關之癌症,諸如白血病及各種其他血液相關癌症;及與神經元增生病有關之癌症,包括腦腫瘤,諸如神經膠質瘤、星形細胞瘤、腦膜瘤、許旺氏細胞瘤(Schwannomas)、垂體瘤、原始神經外胚層瘤(PNET)、髓質母細胞瘤、顱咽管瘤、松果體區腫瘤及皮膚癌,包括基底細胞癌及鱗狀細胞癌。
藉由投與Wnt拮抗劑治療細胞增殖病產生可觀察及/或可量測之以下一或多者之減少或消失:癌細胞數目減少或癌細胞消失;腫瘤尺寸減小;癌細胞浸潤至周邊器官(包括癌症擴散至軟組織及骨骼)被抑制;腫瘤轉移被抑制;在某種程度上抑制腫瘤生長及/或在某種程度上緩解一或多種與特定癌症相關之症狀;發病率及死亡率減少及生活品質改善。就Wnt拮抗劑可預防癌細胞生長及/或殺死現有癌細胞而言,其可為細胞生長抑制劑及/或細胞毒性劑。患者亦可感知此等病徵或症狀之減輕。
用於評定疾病之成功治療及改善之以上參數可易由醫師所熟知之常規程序量測。對於癌症療法而言,可例如藉由評定疾病進展時間(TDP)及/或測定反應率(RR)來量測功效。可藉由分期測試及藉由骨骼掃描及鈣含量測試及可測定擴散至骨骼之其他酶之測試來測定癌轉移。亦可進行CT掃描來檢查擴散至骨盆及該區域中之淋巴結。使用胸部X射線及藉由已知方法量測肝酶含量來分別檢查癌轉移至肺及肝。監測疾病之其他常規方法包括經直腸超音波檢查術(TRUS)及經直腸穿刺生檢(TRNB)。在一特定實施例中,投與Wnt拮抗劑可減小腫瘤負荷(例如減小癌症尺寸或嚴重程度)。在另一特定實施例中,投與Wnt拮抗劑可殺死癌症。
本發明係關於調控Wnt訊號傳導路徑之組合物及方法。在特定實施例中,本發明提供的組合物及方法可藉由調控Wnt路徑之活化來抑制Wnt訊號轉導活性,藉此治療、診斷、預防及/或改善Wnt訊號傳導相關病症。
開發Wnt訊號傳導相關病症療法之當前範例係依靠靶向β-索烴素或β-索烴素下游Wnt路徑組份。然而,最近研究表明即使引發Wnt訊號傳導之事件可能已在下游發生,抑制胞外配位體-受體相互作用組份亦有效降低致瘤性。此外,無效frizzled受體(Frz7胞外域)轉染至癌細胞株(SK-CO-1)中可恢復正常β-索烴素表型。該細胞株由於同種接合子APC-/-
突變而具有活性Wnt訊號傳導。該等細胞當轉移於活體內時亦未顯示腫瘤形成。Vincan等人,Differentiation 2005;73: 142-153。此情況表明在細胞外層面抑制Wnt訊號傳導可下調由下游胞內Wnt訊號傳導路徑組份活化所產生之Wnt訊號傳導。此情況進一步表明,不論已活化Wnt訊號傳導之特定方式,Wnt訊號傳導路徑之抑制劑可用於治療任何Wnt介導病症。
Wnt訊號傳導路徑之調節異常可由編碼各種Wnt訊號傳導路徑組份之基因的體細胞突變所引起。舉例而言,異常Wnt訊號傳導活性已與以下病症之Wnt配位體過度表現相關:非小細胞肺癌(NSCLC)[You等人,Oncogene

由Frz-LRP受體複合物之各種組份之過度表現所產生的異常Wnt訊號傳導亦已與某些癌症相關。舉例而言,LRP5過度表現已與骨肉瘤相關[Hoang等人,Int. J. Cancer
2004;109: 106-111],而Frz過度表現已與諸如以下之癌症相關:前列腺癌[Wissmann等人,見上]、HNSCC[Rhee等人,Oncogene

2001;19: 111-115]。另外,諸如Dishevelled之Wnt訊號傳導路徑組份之過度表現已與諸如以下之癌症相關:前列腺癌[Wissman等人,見上]、乳癌[Nagahata等人,Cancer Sci.
2003;94: 515-518]、間皮瘤[Uematsu等人,Cancer Res.

2001;19: 311-315]。軸蛋白功能損失(LOF)型突變已與以下癌症相關:肝細胞癌[Satoh等人,Nature Genet.

2002;21: 4863-4871]及神經管胚細胞瘤[Dahmen等人,Cancer Res.
2001;61: 7039-7043;Yokota等人,Int. J. Cancer
2002;101: 198-201]。
此外,多種癌症已與經由破壞「降解複合物」(諸如β-索烴素中之功能增加型突變或APC中之功能損失型突變)活化β-索烴素相關。β-索烴素降解之減少致使細胞中存在較大量之功能性β-索烴素,其接著造成靶基因轉錄增加,導致異常細胞增殖。舉例而言,β-索烴素編碼基因(亦即CTNNB1)中之突變已與諸如以下之癌症相關:胃癌[Clements等人,Cancer Res.

其他與異常Wnt訊號傳導相關之病症包括(但不限於)骨質疏鬆症、骨關節炎、多囊性腎病、糖尿病、精神分裂症、血管疾病、心臟疾病、非致癌性增生疾病及諸如阿茲海默氏病(Alzheimer's disease)之神經退化性疾病。
經由p-索烴素之穩定發生的異常Wnt路徑活化在許多結腸直腸癌之腫瘤形成中起著重要作用。據估計80%結腸直腸癌(CRC)在腫瘤抑制因子APC中具有失活突變,使得Wnt訊號傳導連續不斷。此外,有愈來愈多的跡象表明Wnt路徑活化可能與黑色素瘤、乳癌、肝癌、肺癌、胃癌及其他癌症有關。
調節異常之Wnt訊號傳導路徑之活化亦為白血病發展之先兆。實驗證明骨髓及淋巴譜系之致癌性生長取決於Wnt訊號傳導。Wnt訊號傳導已涉及調控骨髓白血病之慢性及急性形式。慢性骨髓性白血病患者之粒細胞-巨噬細胞祖細胞(Granulocyte-macrophage progenitor,GMP)及對治療具有抵抗性之患者的急性轉化期(blast crisis)細胞顯示活化之Wnt訊號傳導。此外,經由軸蛋白之異位表現來抑制β-索烴素可降低活體外白血病細胞之繼代能力,表明慢性骨髓性白血病前驅細胞之生長及更新依賴於Wnt訊號傳導。Wnt過度表現亦使GMP獲得類似幹細胞之長期自我更新特性,證明Wnt訊號傳導對血液譜系正常發展至關重要之假設,但異常Wnt訊號傳導導致祖細胞轉型。
最近研究亦表明淋巴瘤形成亦可受Wnt訊號傳導影響。Wnt-16在攜有E2A-PbX移位的前B細胞白血病細胞株中過度表現,表明自分泌Wnt活性會引起腫瘤形成。McWhirter等人,Proc. Natl. Acad. Sci. USA
96: 11464-11469(1999)。Wnt訊號傳導在正常B細胞祖細胞之生長及存活中之作用進一步證明該觀點。Reya等人,Immunity
13: 15-24(2000);Ranheim等人,Blood
105: 2487-2494(2005)。亦已提出依賴於Wnt之自分泌可調節多發性骨髓瘤(終末分化B細胞癌症)之生長。Derksen等人,Proc. Natl. Acad. Sci. USA
101: 6122-6127(2004)。亦發現原發性骨髓瘤及骨髓瘤細胞株可穩定地表現(亦即獨立於降解複合物)。雖然Wnt訊號傳導組份中不存在突變,但包括Wnt-5A及Wnt-10B之若干組份過度表現表明腫瘤依賴性及癌症自我更新不必定依賴於Wnt訊號傳導路徑組份中出現之突變,而僅依賴於路徑本身之組成性活化。
自我更新之多能幹細胞轉變為骨髓祖細胞的同時伴隨Wnt訊號傳導之下調。Reya等人,Nature
423: 409-414(2003)。類似地,β-索烴素在淋巴祖細胞中之穩定表現可恢復多種分化選擇,即使該等細胞不具有通常與任一細胞類型相關之標記。Baba等人,Immunity
23: 599-609(2005)。
亦已觀察到經由β-索烴素活化Wnt訊號傳導可增加神經祖細胞之循環及擴增且該訊號傳導之損失會引起祖細胞代謝區之損失。Chenn等人,Science
297: 365-369(2002);Zechner等人,Dev. Biol.
258: 406-418(2003)。正如Wnt訊號傳導之正常活化可促進神經元幹細胞之自我更新,異常Wnt路徑活化可在神經系統中致瘤。證明該結論之實驗證據為發現髓質母細胞瘤(小腦兒科腦腫瘤)在β-索烴素及軸蛋白中含有突變,由此表明髓質母細胞瘤由響應於無控制的Wnt訊號傳導而轉型之原始祖細胞產生。Zurawel等人,Cancer Res.
58: 896-899(1998);Dahmen等人,Cancer Res.
61: 7039-7043(2001);Baeza等人,Oncogene
22: 632-636(2003)。因此,有力表明藉由本發明Wnt拮抗劑抑制Wnt訊號傳導可為治療各種神經元增生性病症之有效療法,包括腦腫瘤,諸如神經膠質瘤、星形細胞瘤、腦膜瘤、許旺氏細胞瘤、垂體瘤、原始神經外胚層瘤(PNET)、髓質母細胞瘤、顱咽管瘤、松果體區腫瘤及非癌性神經纖維瘤。
造血幹細胞在多潛能造血幹細胞(HSC)轉變為譜系定型祖細胞(lineage-committed progenitor cell)之過程中產生循環系統之成熟血細胞。亦顯然,Wnt訊號傳導可促進HSC之自我更新及維持且功能異常Wnt訊號傳導導致由HSC產生之各種病症,諸如白血病及各種其他血液相關癌症。Reya等人,Nature
434: 843-850(2005);Baba等人,Immunity
23: 599-609(2005);Jamieson等人,N. Engl. J. Med.
351(7): 657-667(2004)。Wnt訊號傳導通常在幹細胞轉變成定型骨髓祖細胞時減少。Reya等人,Nature 423: 409-414(2003)。
不僅Wnt配位體本身由HSC產生,而且Wnt訊號傳導亦具有活性,由此表明自分泌或旁分泌調節。Rattis等人,Curr. Opin. Hematol.
11: 88-94(2004);Reya等人,Nature
423: 409-414(2003)。另外,β-索烴素與Wnt3a均可促進鼠類HSC及祖細胞之自我更新,而Wnt-5A施用於人類造血祖細胞可促進活體外未分化祖細胞之擴增。Reya等人,見上;Willert等人,Nature
423: 448-452(2003);Van Den Berg等人,Blood
92: 3189-3202(1998)。
除HSC外,顯然,胚胎幹細胞、表皮幹細胞及上皮幹細胞亦回應或依賴於Wnt訊號傳導而維持在未分化之增殖狀態。Willert等人,見上;Korinek等人,Nat. Genet.
19: 379-383(1998);Sato等人,Nat. Med.
10: 55-63(2004);Gat等人,Cell
95: 605-614(1998);Zhu等人,Development
126: 2285-2298(1999)。因此使用本發明Wnt拮抗劑抑制Wnt訊號傳導可為治療造血功能異常所引起之病症(諸如白血病及各種血液相關癌症,諸如急性、慢性、淋巴及骨髓性白血病、骨髓發育不良症候群及骨髓增生病症)之療法。該等病症包括骨髓瘤、淋巴瘤(例如霍奇金氏(Hodgkin's)及非霍奇金氏(non-Hodgkin's)淋巴瘤)、慢性及非進行性貧血、進行性及症狀性血細胞缺乏症、真性紅血球增多症、特發性或原發性血小板增多症、特發性骨髓纖維化、慢性骨髓單核細胞性白血病(CMML)、套細胞淋巴瘤、皮膚T-細胞淋巴瘤、瓦爾登斯特倫巨球蛋白血症(Waldenstrom macroglobinemia)。
Wnt訊號傳導路徑亦可在老年化及年齡相關病症中起關鍵作用。如Brack A S等人,Science
,317(5839):807-10(2007)中所報導,老年化小鼠之肌肉幹細胞經觀察在其開始增殖時可自肌原性譜系轉變為纖維發生譜系。該轉變與老年化肌原性祖細胞中典型Wnt訊號傳導路徑活性增加有關且可由Wnt抑制劑抑制。另外,老年化小鼠之血清組份結合Frizzled蛋白且可造成老年化細胞中Wnt訊號傳導之升高。注射Wnt3A至幼年再生肌肉中可減少增生且增加結締組織之沈積。
在使用加速老年化之Klotho小鼠模型的研究中,Wnt訊號傳導路徑已進一步涉及老年化過程,其中經測定,Klotho蛋白與Wnt蛋白在實體上相互作用且抑制Wnt蛋白。Liu H等人,Science,317(5839):803-6(2007)。在細胞培養模型中,Wnt-Klotho相互作用導致Wnt生物活性之抑制,而Klotho缺乏動物之組織及器官顯示Wnt訊號傳導增加之跡象。
