200407331 玖、發明說明: 【發明所屬之技術領域】 本發明係關於作為有效醫藥成份之新穎化合物,其對大 鼠前列腺之雌激素受體製備物比對大鼠子宮之雄激素受舰 製備物,具有較高的活體外親和性,且在活體内對卵2 子宮有較優先作用、該化合物之製造、該化合物之治療用 途及包含該新穎化合物之醫藥劑型。 這些化學化合物為新穎的、類固醇、組織選擇性之雌激 素。 / 【先前技術】 :激素在治療荷爾蒙缺乏引起之症狀如潮熱、雌激素標 、备之1v宿轉失禁之效果,與成功的使用难激素治療預 防停經前後婦女之骨質流失,已有完整文獻記載且為一般 :斤接受(Grady等人 1992, Ann i l7: ι〇ΐ6_ι〇37)。停 、二後之婦女或因某些其他原因引起卵巢機能障礙之婦女, =雌激素替^治療比沒有以雌激素治療之婦女可降低心血 耳疾病危險i,亦有完整文獻記載(Grady等人,前述引文 中)。 在4知之雌激素或荷爾蒙替代治療中(=HRT),天然雌激 、隹一醇,與由馬尿組成之複合雌性素可單獨或與助孕 素a併使用。亦可以酯化作用所得到之衍生物如17卜戊酸 雌二醇,代替天然雌激素。 因為用於子宮内膜之雌激素的刺激作用,增加罹患子宮 内膜癌之危險性(Hariap,S· 1992, Am J 0bstet Gynecol 166: 85800 200407331 1986-1992),雌激素/助孕素組合製備物較佳係用於荷爾蒙 替代治療。在雌激素/助孕素組合物中助孕素之組份可避免 子i内膜肥大,但不欲的周期内行經出血之發生亦和包含 助孕素之結合物有關。 選擇性雌激素為一種新近之雌激素/助孕素組合製備物 之替代物。至目薊為止,由於其促抗子宮(antiute⑺(即 · 抗雌激素)部分作用,選擇性雌激素已被定義為在腦、骨頭 與血管系統具有類雌激素效應之化合物,但它們對子宮内 膜並無增生作用。 φ 一種部分合乎選擇性雌激素所欲型式之物質係稱為「選 擇性雄激素受體調節物」(Selective Estrogen Recept〇r
Modulators, SERM) (R. F. Kauffman, H. U. Bryant 19955 DNAP 8(9): 531_539)。在本案例中,這些為雌激素受體亞 型「ERa」< 邵分激動劑。然而,該物質型式對於急性停經 後症狀如潮熱是無效的。SERMi 一實例,為最近所引介為 月貝疏鬆症指標之雷諾昔酉分(ral〇xifene)。 治療婦女經常因手術、醫藥或其他方式引起即巢機能障籲 礙等所迨成之生殖疾病,利用新穎之選擇性雌激素亦開始 成為一種新穎可能性之治療。試管内受精治療為建立超過 · 20年之方法。許多以外源性促性腺激素治療卵巢引起之不 · 孕又万法已為吾人所知。藉由施用促性腺成熟激素如fsh (FSH=促濾泡成熟激素)可產生卵巢的刺激而使健康的濾泡 成熟變成可能。 目的··它容納卵母細胞 漉泡為卵巢之功能單位且有兩種 85800 1 200407331 且給予後者生長與成熟的可能性。濾泡發生包含卵巢濾泡 從始基階段至持續增大代表排卵之前之最後階段之竇濾泡 之發育。只有一個發育最佳之竇濾泡可利用排卵釋放一個 成熟之卵母細胞。 具有卵巢引起之不孕(PCOS=多囊性卵巢症候群)之病患 患有濾泡成熟擾亂,其與荷爾蒙及排卵擾亂和不當成熟之 卵母細胞有關。初級與次級濾泡之數目在此比在正常卵巢 約高兩倍(Hughesden等人,Obstet. Gynecol· Survey 37, 1982, ρρ· 59-77)。 有資料指出濾泡發生(與最初的竇濾泡發育有關)之早期 發展階段與促性腺激素不相關。 已知的旁分泌及自體作用因子對早期濾泡發生的影響多 大’並無清楚解釋(Elvin等人,Mol. Cell Endocrinol. 13,1999, pp. 1035-1048 ; McNatty等人,J. Reprod. Fertil· Suppl. 54, 1999, pp. 3-16) 〇 如FSH之f性腺激素在濾泡的成熟中(即早期之竇濾泡至 可進行排卵之成熟滤泡之發展),主要是參與滤泡發生之最 後發育階段。 在活體内與活體外,不孕較佳以促性腺激素(FSH與抗雌 激素)處理(White等人 ’ J. Clin. Endocrinol. Me tab. 81,1996 ρρ· 3 821-3 824)。在活體外受孕處理係將卵母細胞從排卵前 竇滤泡移除使其能夠在試管内成熟至可受精之卵母細胞。 在受精與前胚胎發育後,將1至3個胚胎植入婦女的子宮。 在許多方面,使用外源性之促性腺激素治療伴隨著許多 85800 100407331 危險性與副作用。最大的危險在於卵巢的過度刺激,在嚴 重的案例中可為有嚴重的生命危險(OHSS=卵巢過度刺激 症候群)。其他的副作用為夫婦必須付出試管受精治療的高 成本。負面的副作用如體重增加、氣脹、嗔心、唱吐與一 種迄今未知之發展癌症之長期性危險係歸因於促性腺激素 的治療。 避免上述所提及之缺點與危險性之可能的方法為確保活 體内濾、泡生長之成熟與刺激,在卵巢引起之不孕的案例 中,係在外源性促性腺激素治療開始之前,以合適的活性 成分治療。 雌激素受體Beta (ERp) 最近發現雌激素受體β (ERp)為雌激素受體之第二種亞型 (Kuiper等人(1996),Proc. Natl. Acad. ScL 93: 5925-5930; Mosselman, Dijkema (1996) Febs Letters 392:49-53; Tremblay 等人(1997),Molecular Endocrinology 1 1: 353- 365) o ERp之 表現型式不同於 ERa (Kuiper等人(1996),Endocrinology 138: 863-870)。在大鼠前列腺中ΕΙΙβ因而比ERa佔優勢,而在大 鼠子宮中ERa比ΕίΙβ佔優勢。發現ΕΙΙβ與mRNA之最高濃度 在卵巢中(Couse等人,Endocrinology 138,1997,ρρ· 4612-4613)。 其他具有較高的ERp表現之器官系統包含骨骼(Onoe,Y. 等人,1997,Endocrinology 138: 4509-4512),血管系統 (Register,T. C·,Adams,M. R. 1998,J· Steroid Molec Biol 64: 187-191),泌尿生殖道(Kuiper,G.J.M.等人 1997, 85800 -10- 200407331
Endocrinology 138: 863-870),腸胃道(Campbell-Thopson 1997,BBRC 240: 478-483),與睪丸(Mosselmann,S·等人 1996, FEBS Lett 392 49-53)包括精細胞(Shugrue 等人 1998, Steroids 63: 498-504)。此組織分布暗示雌激素經由ERp調節 器官功能。ERp在該方面是具功能的事實亦顯示於 ERoi-(ERKO)或ΕΙΙβ-(βΕΙΙΚΟ)基因剔除的小鼠研究中··卵巢 切除在ERKO小鼠所產生的骨質流失,可用雌激素取代物將 其消除(Kimbro等人 1998,Abstract OR7-4,Endocrine Society Meeting New Orleans)。在雌ERKO小鼠之血管中的雌二醇亦 抑制了血管中層與平滑肌細胞之增生(Iafrati,M.D.等人 1997, Nature Medicine 3: 545-548)。這些雌二醇之保護作用 可能經由ERp在ERKO小鼠中進行。 ERa與ERP具有不同功能作用的事實在aERKO與βΕΙΙΚΟ 小鼠成功生產後確認。ERa因此在成人子宮、乳腺組織、促 性腺激素活性之負向調節扮演重要的角色,而ΕΙΙβ主要與卵 巢生理的程序有關,尤其是濾泡發生與排卵的過程(Couse 等人,Endocrine Reviews 20,1999, pp. 358-417) 〇 觀察βΕΙΙΚΟ小鼠指出了 ΕΙΙβ在前歹ij腺與膀胱之功能:在 較老的雄小鼠案例中,發生了前列腺與膀胱增生的症狀 (Krege,J.H.等人 1998,Proc Natl Acad Sci 95: 15677· 15682)。此外,雌ERKO 小鼠(Lubahn,D.B.等人 1993,Proc Natl Acad Sci 90: 11162-11166)與雄 ERKO 小鼠(Hess,R.A.等 人 1997,Nature 390: 509-512)與雌 pERKO 小鼠(Krege,J.H·, 1998,Proc Natl Acad Sci 95: 15677-15682)有生殖異常。結 85800 -11 - 200407331 果,與維持睪丸與卵巢功能及生育力有關之雌激素重要功 能因而確認。 根據ER之兩種亞型之不同組織或器官分布,利用具亞型 專一性之配體在特定標的器官上達成選擇性的雌激素作用 疋可犯的。Kuiper等人描述在活體外結合測試中對ERp比 ERcx具有偏好之物質(Kuiper等人(1996),㈣別 863-870)。纟前並無顯#雕激素受體之亞型特異性配體之選 擇性作用在活體内之雌激素敏感參數。 【發明内容】 目標為製備與結合於大鼠前列腺與大鼠子 :疋雌激素文體製備物有關之具有活體外分離之化合物。 這些化合物對大鼠前列腺切激素受體製備物比大鼠子宮 <雌激素受體製備物在活體外具有較高之親和性。 相=專子—性化合物在卵巢產生活體内前受孕作用。同時, 該化合物抑制了與卵巢作用有關之分離。 作用可對y激作用’根據本發明之化合物具有某種保護 乍用了對杬何爾蒙缺乏所⑽之骨質流失。 :=說’可接受具有上述調配之醫藥型式之 物可產生加強卵巢受孕能力而中=。根據本發明之化合 況中,對子宮影響很小。 3’在印果相關不孕的情 【實施方式】 根據本發明,上述之 叫三婦衍生物由提供通式1之9α_取代切 85800 -12- 200407331
