Abstract
本發明關於(S
)-或(R
)-K他命(包括同位素標記的K他命)的前藥及其組成物及用途。作為(S
)-或(R
)-K他命(包括同位素標記的K他命)的前藥之具有式(Ia)或(Ib)之化合物及包含本文中提供的化合物之醫藥組成物係有用於治療或預防CNS疾病。更具體地,相關疾病包括抑鬱和疼痛。
Description
本發明關於醫藥技術領域,且更具體地關於(S
)-或(R
)-K他命(包括同位素標記的K他命)的前藥及其組成物及用途。更具體地,本文揭示的化合物可用來作為NMDA (N
-甲基-D-天冬胺酸)受體拮抗劑,用於治療、預防或減輕與NMDA受體相關之中樞神經系統的神經和精神疾患或疾病(neurological and psychiatric disorder or disease),並且本文揭示的醫藥組成物也具有預防、治療或減輕(lessen)與NMDA受體相關的疾病的功能。更具體地,相關疾病包括抑鬱和疼痛。
抗抑鬱藥是用於治療諸如重度抑鬱症(major depressive disorder, MDD)、低落性情感疾患(dysthymic disorder)、和季節性情感疾患(seasonal affective disorder)等疾病的中樞神經系統療法。MDD,也稱為臨床抑鬱症(clinical depression),是持續兩週或更長時間並干擾一個人進行日常任務和享受以前帶來快樂的活動的能力的病症。
麩胺酸是大腦中主要的興奮性神經傳導介質。與傳統神經傳導介質類似,麩胺酸從神經細胞釋放、與受體結合並藉由再攝取轉運蛋白除去。麩胺酸受體系統非常複雜,且可根據它們的分子和藥理學特性分離成各種不同的受體亞型。大多數跨多種CNS適應症的臨床研究都集中在經由NMDA受體調節麩胺酸功能的藥品上。麩胺酸及其受體亞型在突觸可塑性上扮演基本角色,並影響基本人類情緒、認知和獎賞的過程。額外的角色包括神經發育效果和神經營養效果以及神經退化(neurodegeneration)。
K他命被歸類為NMDA受體拮抗劑,儘管其藥理學概況複雜並且它與許多受體結合。它在50年前首次被美國FDA批准為全身麻醉劑。在化學上,K他命是(R
)-及(S
)-K他命的外消旋混合物。於1998年,(S
)-K他命在EU批准用於全身麻醉。
對於對K他命輸注顯示初步回應的患者而言,重複給藥K他命是一種潛在的抗抑鬱藥維持治療策略(continuation strategy)。對10例在他們一生中未回應達8種抗抑鬱藥之平均的TRD患者進行為期兩週(6次輸注)的靜脈重複給藥K他命,在第6次輸注後導致蒙哥馬利抑鬱評定量表(MADRS;Mongomery-Asberg Depression Rating Scale)平均減少85%。
儘管經由靜脈(i.v.
)輸注K他命具有有效效果及與治療治療抗性抑鬱症的其他藥品相比有利的位置,但這種給藥方案要求患者在診所獲得治療。K他命已經在人類中進行了研究,以評估其口服生體可用率。結果發現,由於大規模的首渡代謝(first-pass metabolism),K他命在人類僅顯示17%的口服生體可用率,這阻止了它開發口服方案。此外,K他命的副作用可能與快速濃注給藥(bolus dosing)後的高Cmax有關。
為了克服K他命的藥物動力學缺陷,前藥途徑將被用於鑑定可經由口服投予顯著改善K他命的藥物動力學概況之可行的K他命衍生物。可能所欲者為持續釋放調配劑,以除去藥品血漿濃度的峰值和谷值,以避免潛在的副作用。

額外化學描述
額外化學描述
本文給出的任何式子旨在表示出具有結構式所示結構的化合物以及某些變體或形式。例如,本文給出的任何式子的化合物可具有不對稱或手性中心,因此以不同的立體異構形式存在。通式化合物的所有立體異構體,包括光學異構體、對映異構體和非對映異構體,以及它們的混合物,都被認為落入該式子的範圍內。此外,某些結構可以以幾何異構體(即順式和反式異構體)、互變異構體或阻轉異構體的形式存在。所有這類異構形式及其混合物在本文中都被認為是本發明的一部分。因此,本文給出的任何式子旨在表示出外消旋體、一種或多種對映體形式、一種或多種非對映體形式、一種或多種互變異構體或阻轉異構體形式、及其混合物。
“立體異構體”是指具有相同化學組成但在空間中原子或基團的排列方面不同的化合物。立體異構體包括對映異構體、非映映異構體、構型異構體(旋轉異構體)、幾何(順式/反式)異構體、阻轉異構體等。
“手性”是指具有鏡像夥伴不可重疊性的分子,而術語“非手性”是指可與其鏡像夥伴重疊的分子。
“對映異構體”是指化合物的兩種立體異構體,它們是彼此不可重疊的鏡像。
“非對映異構體”是指具有兩個或多個手性中心且其分子彼此不是鏡像的立體異構體。非對映異構體具有不同的物理性質,例如熔點、沸點、光譜性質或生物活性。可以在高拆分率分析程序(諸如電泳)和色譜法(諸如HPLC)下分離非對映異構體的混合物。
此處使用的立體化學定義和慣例通常地遵循S. P. Parker, Ed., McGraw-Hill Dictionary of Chemical Terms (1984) McGraw-Hill Book Company, New York;以及Eliel, E. and Wilen, S., "Stereochemistry of Organic Compounds", John Wiley & Sons, Inc., New York, 1994。
許多有機化合物以光學活性形式存在,即它們具有旋轉偏振光平面的能力。在描述光學活性化合物時,前綴詞D和L、或R
和S
用於表示有關於其之手性中心的分子絕對構型。前綴詞d
和l
或(+)和(-)用於表示化合物所旋轉平面偏振光的符號,(-)或l
表示該化合物是左旋的。前綴有(+)或d
的化合物是右旋的。特定的立體異構體可以稱為對映異構體,而這種立體異構體的混合物稱為對映異構體混合物。對映異構體的50:50混合物被稱為外消旋混合物或外消旋體,其可以發生在於化學反應或程序中沒有立體選擇性或立體特異性的情況下。
本文揭示的一或多種化合物的任何不對稱原子(例如,碳等)可以採外消旋富集或對映異構富集構型,(R
)-、(S
)-或(R,S
)-構型。在某些實施態樣中,各不對稱原子具有至少50 %的對映異構過量、至少60 %的對映異構過量、至少70 %的對映異構過量、至少80 %的對映異構過量、至少90 %的對映異構過量、至少95 %的對映異構過量、或至少99%的對映異構過量的(R
)-或(S
)-構型。
取決於起始原料和程序的選擇,化合物可以呈可能立體異構體中的一種或其混合物的形式存在,例如外消旋體和非對映異構體混合物,這取決於不對稱碳原子的數量。光學活性(R
)-和(S
)-異構體可以使用手性合成組元或手性試劑製備,或使用常規技術拆分。如果化合物含有雙鍵,則取代基可以是E
或Z
構型。如果化合物含有經二取代的環烷基,則環烷基取代基可以具有相對於相同環烷基骨架的另一取代基的順式或反式構型。
任何所得立體異構體混合物可基於構成分的物理化學差異分離成純的或基本上純的幾何異構體、對映異構體、非對映異構體,例如,藉由色譜法和/或分段結晶。藉由本技術領域具有通常知識者已知的方法,例如藉由分離其非對映異構鹽,可以將任何所得的最終產物或中間體的外消旋體拆分成光學對映體。外消旋產物也可以藉由手性色譜法拆分,例如使用手性吸附劑的高效液相色譜法(HPLC)。較佳的對映異構體也可以藉由不對稱合成來製備。參見,例如,Jacques,et al.

非映射異構混合物可以藉由本技術領域具有通常知識者熟知的方法,諸如例如藉由色譜法和/或分段結晶,而基於它們的物理化學差異分離成它們各自的非對映異構體。對映異構體可藉由下列分離:與適當的光學活性化合物(例如手性助劑諸如手性醇或莫雪氏(Mosher’s)醯氯)反應而將對映異構混合物轉化為非對映異構體混合物;或藉由形成非對映異構鹽的混合物、分離非對映異構體並將單個非對映異構體轉化(例如,水解或脫鹽)成相應的純對映異構體。也可以使用手性HPLC柱分離對映異構體。
本發明化合物可形成醫藥上可接受的鹽,這也落入本發明的範圍內。“醫藥上可接受的鹽”是指式A化合物的游離酸或鹼的鹽,其無毒、生理上可耐受、與其中配製有彼的醫藥組成物可相容、以及以其他方式適合於調配和/或投予給對象。除非另有說明,否則本文提及的化合物應理解為包括該化合物的醫藥上可接受的鹽。
化合物的鹽包括與無機和/或有機酸形成的酸成鹽,以及與無機和/或有機鹼形成的鹼性鹽。此外,當給定化合物含有鹼性部分(諸如但不限於吡啶或咪唑)和酸性部分(諸如但不限於羧酸)時,本技術領域具有通常知識者將會認知到該化合物可能以兩性離子(“內鹽”)存在;這些鹽包括在本文所用的術語“鹽”中。本發明化合物的鹽可以藉由例如使化合物與某量(諸如等量)的合適的酸或鹼在介質中,諸如其中鹽會沉澱的介質或在水性介質中反應然後凍乾而製備。
示例性鹽包括但不限於硫酸鹽、檸檬酸鹽、乙酸鹽、草酸鹽、氯化物鹽、溴化物鹽、碘化物鹽、硝酸鹽、硫酸氫鹽、磷酸鹽、酸式磷酸鹽、異菸鹼酸鹽、乳酸鹽、水楊酸鹽、檸檬酸鹽、酒石酸鹽、油酸鹽、丹寧酸鹽、泛酸、酒石酸氫鹽、抗壞血酸鹽、琥珀酸鹽、馬來酸鹽、龍膽酸鹽、富馬酸鹽、葡萄糖酸鹽、葡萄醣醛酸鹽、糖酸鹽(saccharate)、甲酸鹽、苯甲酸鹽、麩胺酸鹽、甲烷磺酸鹽(“甲磺酸鹽”)、乙烷磺酸鹽、苯磺酸鹽、對甲苯磺酸鹽和撲酸鹽(即1,1’-亞甲基雙(2-羥基-3-萘甲酸鹽))。醫藥上可接受的鹽可以涉及含括另外的分子諸如乙酸根離子、琥珀酸根離子或其他抗衡離子在內。抗衡離子可以是安定母體化合物上的電荷的任何有機或無機部分。此外,醫藥上可接受的鹽在其結構中可具有多於一個帶電原子。於多個帶電原子是醫藥上可接受的鹽的一部分的情形中可具有多個抗衡離子。因此,醫藥上可接受的鹽可以具有一個或多個帶電原子和/或一個或多個抗衡離子。
示例性的酸加成鹽包括乙酸鹽、抗壞血酸鹽、苯甲酸鹽、苯磺酸鹽、硫酸氫鹽、硼酸鹽、丁酸鹽、檸檬酸鹽、樟腦酸鹽、樟腦磺酸鹽、富馬酸鹽、鹽酸鹽、氫溴酸鹽、氫碘酸鹽、乳酸鹽、馬來酸鹽、甲烷磺酸鹽、萘磺酸鹽、硝酸鹽、草酸鹽、磷酸鹽、丙酸鹽、水楊酸鹽、琥珀酸鹽、硫酸鹽、酒石酸鹽、硫氰酸鹽、甲苯磺酸鹽(toluenesulfonates)(也稱為甲苯磺酸鹽(tosylates))等。
示例性鹼性鹽包括銨鹽、鹼金屬鹽(諸如鈉鹽、鋰鹽和鉀鹽)、鹼土金屬鹽(諸如鈣鹽和鎂鹽)、與有機鹼,例如有機胺(諸如二環己胺、第三丁基胺)形成的鹽、與胺基酸(諸如精胺酸、離胺酸等)形成的鹽。鹼性含氮基團可以用諸如低級烷基鹵化物(例如甲基氯化物、甲基溴化物、甲基碘化物、乙基氯化物、乙基溴化物、乙基碘化物、丁基氯化物、丁基溴化物和丁基碘化物)、二烷基硫酸鹽(例如二甲基硫酸鹽、二乙基硫酸鹽和二丁基硫酸鹽)、長鏈鹵化物(例如癸基氯化物、癸基溴化物、癸基碘化物、月桂基氯化物、月桂基溴化物、月桂基碘化物、硬脂基氯化物、硬脂基溴化物、硬脂基碘化物、低級烷基鹵化物)、芳烷基鹵化物(例如苄基溴化物和苯乙基溴化物)等季銨化。
另外,通常認為適合於從醫藥化合物形成醫藥上有用的鹽的酸和鹼被討論於例如P. Stahlet al
, Camille G. (eds.) Handbook of Pharmaceutical Salts. Properties, Selection and Use.;(2002) Zurich: Wiley-VCH; S. Bergeet al

, The Practice of Medicinal Chemistry (1996), Academic Press, New York;及The Orange Book (Food & Drug 投予, MD, available from FDA)中。這些揭示內容藉由引入併入本文參考。
另外,本文所述的任何化合物也旨在指稱任何未溶劑化的形式,或這種化合物的水合物、溶劑合物或同質異晶物,及其混合物,即使這些形式未明確列出亦然。“溶劑合物”是指本發明化合物與一種或多種溶劑分子的物理結合。這種物理結合涉及各式程度的離子和共價鍵結,包括氫鍵結。在某些情形下,溶劑合物將能夠區隔開(isolation),例如當一種或多種溶劑分子併入結晶固體的晶格中時。“溶劑合物”涵蓋溶液相和可區隔開的溶劑合物。合適的溶劑合物包括與醫藥上可接受的溶劑諸如水、乙醇等形成的溶劑合物。在一些實施態樣中,溶劑是水,溶劑合物是水合物。
本發明的一種或多種化合物可視需要地轉化為溶劑合物。製備溶劑合物的方法通常是已知的。因此,例如M. Cairaet al.
, J. Pharmaceutical Sci., 93(3), 601-611 (2004)描述了抗真菌劑氟康唑(fluconazole)在乙酸乙酯中和來自水的溶劑合物的製備。溶劑合物、半溶劑合物、水合物等的類似製劑描述於E. C. van Tonderet al
, AAPS PharmSciTech., 5(1), article 12 (2004);及A. L. Bingham et al, Chem. Commun., 603-604 (2001)中。典型的非限制性程序包括在高於環境溫度下將本發明化合物溶解在適量的溶劑(有機溶劑或水或其混合物)中,並以足以形成結晶的速率冷卻溶液,然後藉由標準方法分離結晶。分析技術,諸如紅外光譜,顯示溶劑(或水)存在於結晶中而為溶劑合物(或水合物)。
本發明也涉及式(A)化合物的醫藥活性代謝物,以及這些代謝物在本發明方法中的用途。“醫藥活性代謝物”是指式(A)化合物或其鹽在體內代謝的醫藥活性產物。化合物的活性代謝物可使用本領域已知或可得的常規技術測定。參見,例如,Bertoliniet al.

F或11
C標記的化合物可能特別適用於PET或SPECT研究。此外,用較重的同位素諸如氘(即2

式(Ia)~(Vd)化合物可採鹽的形式存在。在一些實施態樣中,鹽是醫藥上可接受的鹽。本發明之醫藥上可接受的鹽可以藉由常規化學方法從鹼性或酸性部分合成。通常,這些鹽可以藉由使這些化合物的游離酸形式與化學計算量的適當鹼(諸如氫氧化鈉、氫氧化鈣、氫氧化鎂、氫氧化鉀、碳酸鈉、碳酸鈣、碳酸鎂、碳酸鉀、碳酸氫鈉、碳酸氫鈣、碳酸氫鎂、碳酸氫鉀等)反應,或藉由使使這些化合物的游離鹼形式與化學計算量的適當酸反應來製備。這些反應典型在水或有機溶劑中進行,或在兩者的混合物中進行。通常,在可行的情況下,所欲者為使用非水性介質,像是乙醚、乙酸乙酯、乙醇、異丙醇或乙腈。找到額外之合適的鹽的列表可以在例如“Remington’s Pharmaceutical Sciences

本發明化合物的組成物和製劑和投予
在一方面,本文中提供的是一種醫藥組成物,其包括式(Ia)~(Vd)的化合物或彼之立體異構體、互變異構體、N-氧化物、溶劑合物、代謝物、醫藥上可接受的鹽或前藥。視需要地,醫藥組成物醫進一步包含至少一種醫藥上可接受的載劑、佐劑、或賦形劑,和視需要的其他治療組成分和/或預防組成分。
合適的載體、佐劑和賦形劑是本技術領域具有通常知識者熟知的並且詳細描述在諸如Ansel h。C.et al.
, Ansel’s Pharmaceutical Dosage Forms and Drug Delivery Systems (2004) Lippincott, Williams & Wilkins, Philadelphia;Gennaro A. R.et al.
, Remington: The Science and Practice of Pharmacy (2000) Lippincott, Williams & Wilkins, Philadelphia;及Rowe R. C., Handbook of Pharmaceutical Excipients (2005) Pharmaceutical Press, Chicago中。
本文所用的“醫藥上可接受的賦形劑”是指醫藥上可接受的材料、組成物或涉及賦予醫藥組成物形式或稠度的媒劑。當混合時,各賦形劑必須與醫藥組成物的其它組成分可相容,從而避免了當投患者時會顯著降低本發明化合物效力的相互作用以及將導致醫藥上不可接受的組成物。此外,各賦形劑當然必須具有足夠高的純度以使其為醫藥上可接受的。
合適的醫藥上可接受的賦形劑將取決所選的具體劑型而變化。另外,可以選擇合適的醫藥上可接受的賦形劑,這是為了它們可以在組成物中起到特定功能。例如,可以選擇某些醫藥上可接受的賦形劑,因為它們促進產生均一(uniform)劑型。可以選擇某些醫藥上可接受的賦形劑,因為它們促進產生安定的劑型。可以選擇某些醫藥上可接受的賦形劑,因為它們一旦投予到患者促進從一個器官或身體的一部分攜帶或運輸本發明的化合物到另一個器官或身體的一部分。可以選擇某些醫藥上可接受的賦形劑,因為它們增強患者的依從性。
合適的醫藥上可接受的賦形劑包括以下類型的賦形劑:稀釋劑、填充劑、黏合劑、崩解劑、潤滑劑、助流劑、造粒劑、包衣劑、潤濕劑、溶劑、共溶劑、懸浮劑、乳化劑、甜味劑、調味劑、掩味劑、著色劑、抗結塊劑、保濕劑、螯合劑、增塑劑、增黏劑、抗氧化劑、防腐劑、安定劑、表面活性劑和緩衝劑。本技術領域具有通常知識者將理解,某些醫藥上可接受的賦形劑可以起到一種以上的作用,並且可以作為替代功能,這取決於調配劑中存在多少賦形劑以及調配劑中存在哪些其他組成分。
技術人員具有本領域的知識和技能,而使得他們能夠選擇於用於本發明的適當量的合適醫藥上可接受的賦形劑。此外,對本技術領域具有通常知識者來說,有許多描述醫藥上可接受的賦形劑之可得的資源,並且該等資源可用於選擇合適的醫藥上可接受的賦形劑。實例包括Remington’s Pharmaceutical Sciences (Mack Publishing Company),The Handbook of Pharmaceutical Additives (Gower Publishing Limited),及The Handbook of Pharmaceutical Excipients (the American Pharmaceutical Association and the Pharmaceutical Press)。
