Description
近年來,通過更好地理解與目標疾病相關的蛋白質和其他生物分子的結構,對尋找新型治療劑提供了極大的幫助。這些蛋白質中的一種重要類型是中樞神經系統(CNS)細胞表面受體,西格瑪(σ)受體,該中樞神經系統細胞表面受體可能與煩躁不安、阿片類藥物的致幻和心臟刺激效應有關。σ受體生物學和功能研究證據已經表明σ受體配體可用於治療精神病和運動障礙(如肌張力障礙和遲發性運動障礙),以及亨廷頓舞蹈症或圖雷特綜合征相關的運動障礙和帕金森氏症(Walker,J.M.等,
Pharmacological Reviews,1990,42,355)。已見報道的是,已知的σ受體配體林卡唑(rimcazole)顯示出在精神病的治療中具有臨床療效(Snyder,S.H.,Largent,B.L.J.Neuropsychiatry 1989,1,7)。σ結合位點對某些阿片苯基嗎啡類的右旋異構體具有優先親和力,例如(+)-SKF 10047、(+)-環唑辛和(+)-噴他唑辛,也對一些嗜睡症藥物具有優先親和力,例如氟呱啶醇。
σ受體具有至少兩種亞型,其可以通過這些藥理活性藥物的立體選擇性異構體進行識別。SKF 10047對σ-1(σ1)受體具有納摩爾級親和力,並對σ-2(σ2)亞型具有微摩爾級的親和力。氟呱啶醇對兩種亞型都具有相似的親和力。雖然孕酮已經被認為是內源性σ配體之一,但內源性σ配體是未知的。可能的σ位點介導的藥物效應包括谷氨酸鹽受體功能調節、神經遞質回應、神經保護、行為和認知(Quirion,R.等Trends Pharmacol.Sci.,1992,13:85-86)。大多數研究表明σ結合位點(受體)是信號轉導級聯的質膜要素。報導為選擇性σ配體的藥物已被鑒定為抗精神病藥(Hanner,M.等,Proc.Natl.Acad.Sci.,1996,93:8072-8077)。在CNS、免疫系統和內分泌系統中存在σ受體暗示了其作為這三個系統之間紐帶的可能性。
鑒於σ受體激動劑或拮抗劑的潛在治療應用,大量工作集中在尋找選擇性配體上。因此,現有技術公開了不同的σ受體配體。1-(4-(2-((1-(3,4-二氟苯基)-1H-吡唑-3-基)甲氧基)乙基)哌-1-基)乙酮是有前景的σ受體配體之
一。該化合物及其合成被WO 2011/147910公開並要求保護。
1-(4-(2-((1-(3,4-二氟苯基)-1H-吡唑-3-基)甲氧基)甲基)哌-1-基)乙基酮是高選擇性的σ-1(σ1)受體拮抗劑。它在治療和預防慢性和急性疼痛,尤其是神經性疼痛中表現出了很強的止痛活性。該化合物的分子量為364.39Da,pKa為6.37。該化合物的結構式為:
為進行其藥物開發和實現其潛能,現有技術中存在對其他形式的1-(4-(2-((1-(3,4-二氟苯基)-1H-吡唑-3-基)甲氧基)乙基)哌-1-基)乙酮的需要,以促進該活性藥物成分的更好的製劑的製備。
在這方面,該化合物的其它形式可以具有明顯不同的性質,例如增強的熱穩定性、更高純度或改善的生物利用度(例如更好的吸收、溶解模式)。具體化合物的形式也可以促進化合物製劑的製造(例如增強的流動性)、處理和儲存(例如非吸濕性、保質期長)或允許使用較低劑量的治療藥物,從而降低其潛在的副作用。因此,提供對藥物用途具有改進的性質的形式很重要。
在本發明中,對不同形式的1-(4-(2-((1-(3,4-二氟苯基)-1H-吡唑-3-基)甲氧基)乙基)哌-1-基)乙酮進行廣泛的研究後,意外地發現並證明,其一些結晶鹽,特別是鹵化氫鹽和簡單二元羧酸鹽具有便於生產、處理、儲存和/或治療的特性。
在更優選的實施方式中,1-(4-(2-((1-(3,4-二氟苯基)-1H-吡唑-3-基)甲氧基)乙基)哌-1-基)乙酮的結晶鹽選自其鹽酸鹽、馬來酸鹽、富馬酸鹽、丙二酸鹽、琥珀酸鹽、草酸鹽和/或氫溴酸鹽組成的組中。
在另一方面,本發明涉及1-(4-(2-((1-(3,4-二氟苯基)-1H-吡唑-3-基)甲氧基)乙基)哌-1-基)乙酮的結晶鹽用作藥物的用途,優選用作σ配體,即用於σ受體介導的疾病或病症的治療和/或預防。
本發明的另一方面涉及治療和/或預防σ受體介導的疾病的方法,該方法包括向需要這種治療的患者施用治療上有效量的如上限定的化合物或其藥物組合物。
這些方面和其優選的實施方式也額外地在申請專利範圍裡進行限定。

化合物1-(4-(2-((1-(3,4-二氟苯基)-1H-吡唑-3-基)甲氧基)乙基)哌-1-基)乙酮難以結晶。在不同的條件下嘗試,無論是從幾種溶劑沉澱還是蒸餾,在所有情況下得到的都是油狀物。這種油狀物用晶種在非常緩慢的情況下結晶,幾天後才會得到結晶形式。結晶困難是由於其熔點低(46℃)。因此,存在對熔點高於46℃的1-(4-(2-((1-(3,4-二氟苯基)-1H-吡唑-3-基)甲氧基)乙基)哌-1-基)乙酮其它形式的需要,其中,其具有簡化分離、純化和處理常式的優勢。
實際上,在廣泛的篩選鹽後,已經觀察到的是,大量酸(例如硫酸、苯磺酸、乙酸或L-酒石酸)在與1-(4-(2-((1-(3,4-二氟苯基)-1H-吡唑-3-基)甲氧基)乙基)哌-1-基)乙酮混合時沒有得到固體,相反總是得到油狀物。
此外,在適合得到固體形式的鹽的酸中,已經意外地
發現,強無機一元酸和有機二酸在易於製備、物理穩定性、擴大生產、溶解度等方面能夠提供更好的結果。特別是鹽酸和馬來酸。這些結果是通過得到熔點的增量和用於例如熱力學溶解度或例如Cmax或AUC的藥代動力學參數的的某些特殊性能值來示出的,以便找到具有用於藥物用途所需性質的新型替代形式。
在另一優選的方面,本發明涉及1-(4-(2-((1-(3,4-二氟苯基)-1H-吡唑-3-基)甲氧基)乙基)哌-1-基)乙酮的結晶鹽選自其鹽酸鹽、馬來酸鹽、富馬酸鹽、丙二酸鹽、琥珀酸鹽、草酸鹽和/或氫溴酸鹽組成的組中。
在更優選的方面,本發明涉及1-(4-(2-((1-(3,4-二氟
苯基)-1H-吡唑-3-基)甲氧基)乙基)哌-1-基)乙酮鹽酸鹽和1-(4-(2-((1-(3,4-二氟苯基)-1H-吡唑-3-基)甲氧基)乙基)哌-1-基)乙酮的馬來酸鹽。
如前面所指出的,已見報道的是1-(4-(2-((1-(3,4-二氟苯基)-1H-吡唑-3-基)甲氧基)乙基)哌-1-基)乙酮為高度選擇性σ-1(σ1)受體拮抗劑,在治療和預防慢性和急性疼痛,特別是神經性疼痛中表現出了很強的止痛活性(參見WO2011/147910)。
現在已經發現的是,選自馬來酸鹽、富馬酸鹽、草酸鹽、丙二酸鹽和琥珀酸鹽組成的組的1-(4-(2-((1-(3,4-二氟苯基)-1H-吡唑-3-基)甲氧基)乙基)哌-1-基)乙酮的結晶鹽特別適合用作藥物。
現在已經發現的是,選自鹽酸鹽、馬來酸鹽、富馬酸鹽、丙二酸鹽、琥珀酸鹽、草酸鹽和/或氫溴酸鹽組成的組的1-(4-(2-((1-(3,4-二氟苯基)-1H-吡唑-3-基)甲氧基)乙
基)哌-1-基)乙酮的結晶鹽特別適合用作藥物。
現在已經發現的是,1-(4-(2-((1-(3,4-二氟苯基)-1H-吡唑-3-基)甲氧基)乙基)哌-1-基)乙酮鹽酸鹽或1-(4-(2-((1-(3,4-二氟苯基)-1H-吡唑-3-基)甲氧基)乙基)哌-1-基)乙酮馬來酸鹽特別適合用作藥物。

對在pH7.4和pH2下的熱力學溶解度的通用方案進行說明。
A)在pH值為7.4時的熱力學溶解度
緩衝溶液
pH7.4(25毫摩爾)的磷酸鹽緩衝液製備如下:
製備25mM的Na2HPO4.12H2O(對1升的水,重量為8.96克)的溶液。
製備25mM的KH2PO4(對1升水,重量為3.4克)的溶液。
將磷酸二鈉溶液(812毫升)和磷酸鉀(182毫升)溶液混合,且pH檢查為7.4。
- 精密分析天平梅特勒-托萊多(Mettler Toledo)AT20
- 分析天平梅特勒-托萊多PJ300
- 液相色譜Waters Alliance 2695
- 微量離心管在25℃ 1250轉的攪拌器恒溫控制
- 合併半微量電極的pH計
大約4毫克的化合物在HPLC小瓶(重複)中溶解在1mL緩衝溶液中。在25℃在熱混合器舒適系統(Thermomixer Comfort system)攪拌24小時,以達到熱力學平衡,溶液以3000轉離心15分鐘。
所得上層用玻璃吸管收集並轉移到HPLC小瓶中以將它們(10微升)直接注入到HPLC儀器中。
標準液是在甲醇中制得的以確保化合物的整體溶解度。標準校準液的製備如下所示:
溶液A:在1mL甲醇中有4毫克(4000微克/毫升)
溶液B:將0.5毫升溶液A溶解於5ml甲醇(400微克/毫升)
溶液C:將1毫升溶液B溶解於10ml甲醇(40微克/毫升)
溶液D:將5毫升溶液C溶解於50mL甲醇(4微克/毫升)
溶液E:將4毫升溶液D溶解於10ml甲醇(1.6微克/毫升)
標準曲線通過注射10μL標準液創建,以更稀釋的標準液開始。也注射空白溶液,以檢測是否存在污染。
重複注射10微升受試物質,且平均峰面積內插在校準曲線中(見下文的實施例表格)。
色譜柱:XBridge C18(或類似)2.5微米4.6×50毫米
溫度:35℃
流動相:乙腈/碳酸氫銨10mM。
梯度:0-3.5分鐘:從15%ACN到95%ACN
3.5-5分鐘:95%ACN
5-6分鐘:95%至15%ACN
6-8分鐘:15%ACN
流速:1.5毫升/分鐘
檢測:大約最高紫外線波長。
B)在pH值為2時的熱力學溶解度
用HCl 0.01N代替緩衝液進行之前相同的程式。
根據所描述的方案,將實施例1完全溶解,因此溶解度高於4000微克/毫升(pH值=7.4)(見表5和表6)。
根據所描述的方案,將實施例2完全溶解,因此溶解度高於4000微克/毫升(pH值=7.4)(見表7和表8)。
使用由Harlan提供的重250到300克(±20)的雄性Wistar大鼠。水和食物在整個研究過程中可隨意提供。
兩隻大鼠(R1和R2)在藥物動力學口服研究中使用。
溶於0.5%羥丙基甲基纖維素(1毫克/毫升)的測試
化合物的單劑量通過口腔灌食給藥[10毫克/千克的游離堿(實施例0)]。對每個大鼠,一系列血液樣品在15和30分鐘、1、2、3、5、7和24小時收集。
從隱靜脈將血液收集到肝素化管中。血漿通過在4℃和2280×g的情況下血液離心10分鐘得到並在-80℃下保存直至分析。
血漿樣品中的測試化合物的濃度通過最小二乘線性回歸法使用10個點的標準曲線來確定。校準曲線用在DMSO中1毫克/毫升工作溶液的空白血漿製備。
樣品在分析當天在室溫下解凍。在樣品的血漿蛋白沉澱後,校準標準液與乙腈(1:4.3;V/V)混合,將混合物渦旋並離心(4℃和16090×g下10分鐘)。最後,將所得的上清液的等分試樣在分析前用水(0.1%甲酸)稀釋到1/10。
測試化合物的血漿濃度由高效液相色譜-三重四極杆質譜法(HPLC-MS/MS)通過下面的方法確定:色譜柱:Atlantis®T3柱(2.1×100mm,3μm)(Waters)。
流動相:A:0.0155%甲酸水
B:0.0155%甲酸乙腈
自動進樣器清洗:溶劑1:乙腈
溶劑2:5%乙腈+95%水
如曲線(AUC)、血漿濃度峰值(Cmax)、達到濃度峰值的時間(Tmax)、口服生物利用度(F)、總血漿清除率(CL)、在穩定狀態的分佈容積(Vss)、平均保留時間(MRT)和終末半衰期(T1/2)的標準藥代動力學參數是由血漿濃度-時間曲線的非隔室分析(Phoenix v.6.2.1.51,Pharsight,CA))測定。
- 大鼠口服給藥10mg/kg後,實施例1在給藥0.6小時後,達到血漿濃度峰值約1000ng/ml(表9),表明了良好的口服生物利用度(60%)(表10)。
- 終末半衰期很短(<1小時)。此終末半衰期涉及高血漿清除率(70%肝臟血流量)。
- 實施例1示出體積分佈比全身水分體積(1.2 VS 0.6 l/kg)高。此結果表明,實施例1能夠穿過細胞膜和/或對組織成分具有親和力。
當體積分佈比全身水分高時,則認為該化合物是廣泛分佈,並可以預期呈現出良好的治療靶標暴露。
- 大鼠口服給藥10mg/kg後,實施例2在給藥0.4小時後,達到大約1213ng/ml的血漿峰值濃度(表11)。
- 終末半衰期是適度的(1.5小時)(表12)。
在給藥0.63h(實施例1)和0.38h(實施例2)後達到峰值血漿濃度,表明了快速的吸收,因此可以預期能快速見效。
優選高攝入,以保證化合物所需的活性。給藥10毫克/千克後,曲線下的面積(AUC)給出約2600(實施例1)和約2000(實施例2)ng.h/ml的攝入值,被認為足夠高了。
生物利用度(F)是到達全身迴圈不改變的劑量的分數。所發現的良好的值(實施例1的60%和實施例2的45%)被認為可以刺激足夠高的攝入,也有效避免低生物利用度的化合物的血液濃度的患者到患者變化很大的風險。
