疼痛是臨床上最常見的症狀之一,是繼呼吸、脈搏、血壓和體溫之後的第五生命體征,嚴重影響患者的生活質量。據統計,2018年全球鎮痛藥市場約為360億美元,預計2023年將達到560億美元。其中急性中重度主要依賴於鴉片類藥物,占鎮痛藥市場份額的三分之二左右,未來將以2.5%的年複合增長率穩定增長。而以神經病理性疼痛(neuropathic pain)和關節炎疼痛為主的慢性疼痛患者數量逐年增加,預計市場將呈現18%左右的年複合增長率,是驅動未來十年全球疼痛市場持續增長的主要推動力。
神經病理性疼痛是由於外周軀體感覺神經系統的損傷或疾病導致的一種慢性疼痛,其症狀包括自發性疼痛以及對正常無害刺激產生的痛覺超敏。誘發神經病理性疼痛的常見病因包括:糖尿病、帶狀皰疹、脊髓損傷、中風、多發性硬化、癌症、HIV感染、腰或頸神經根性神經病變和創傷或術後神經損害等等。骨關節炎又稱退化性關節炎,是由多種因素引起的骨關節軟骨退化,能導致關節骨表面凸凹不平,並有可能形成骨刺,臨床表現主要是關節疼痛和關節僵硬。長期疼痛不但影響患者睡眠、工作和生活能力,還會增加抑鬱或焦慮等感情障礙的發病率,因此給患者家庭及社會帶來沉重的經濟負擔。
根據國際疼痛學會神經病理性疼痛特別小組(NeuPSIG)發佈的數據,神經病理性疼痛患病率約3.3%-8.2%。據此推算,僅中國國內就有至少5千萬以上患者。2017年,美國、日本和歐盟五大市場(法國、德國、意大利、西班牙和英國)共有3050萬例神經病理性疼痛患者,並呈逐年上升趨勢。神經病理性疼痛是最難治療的疾病之一,目前大多數治療方案仍不能達到令人滿意的效果。有報道指出,能通過藥物治療而及時止痛的門診患者僅有14.9%,即約85%的疼痛病人並沒有得到及時有效的藥物治療,因而一些病人不得不尋求手術介入性治療。目前臨床上用於神經病理性疼痛治療的一線藥物主要是鈣離子通道調節劑(如普瑞巴林、加巴噴丁)、三環類抗抑鬱藥和5-羥色胺、去甲腎上腺素再攝取抑制藥(如度洛西汀、文拉法辛等抗驚厥、抗抑鬱的藥物)。這些藥療效有限並伴隨有各種不良反應。度洛西汀是神經病理性疼痛治療的一線用藥之一,主要副作用包括胃腸道反應、噁心、嗜睡、口乾、多汗和頭暈等,由此導致的停藥率到達15%-20%。抗癲癇藥物加巴噴丁和普瑞巴林是治療神經病理性疼痛的主要藥物,會引起頭暈、嗜睡、周圍性水腫、體重增加、虛弱、頭痛和口乾等諸多不良反應。近年來還發現普瑞巴林會導致極少部分患者出現藥物使用相關的自殺觀念和自傷行為。
骨關節炎患者數量龐大,預計目前全世界骨關節炎患者超過4億,中國患者人數已過億。骨關節炎疼痛目前也沒有有效的治療方法。臨床上有物理療法和藥物療法和手術治療。物理療法包括熱療,水療,超聲和按摩等,另外輔助用具減少關節壓力緩解疼痛,但效果均有限,大部分依然需要依賴藥物進行治療。這些藥物均存在不同程度的副作用。非類固醇抗炎藥只適用於輕中度疼痛,而且有胃腸道副作用和心腦血管方面的風險。鴉片類鎮痛藥用於重度疼痛,但有明顯的噁心嘔吐、便秘和藥物依賴等副作用,不適合長期服用。因此,研發靶向新靶點新機制以及安全有效的鎮痛藥物,滿足未被滿足的臨床需求,具有重要的經濟意義和社會意義。
近年來的研究成果逐步揭示了鈉離子通道亞型1.8(NaV1.8)在痛覺的發生和傳遞方面起重要作用。 NaV1.8是一種電壓門控鈉離子通道,主要表達在包括感覺神經元在內的傳入神經元上,通過控制鈉離子進出細胞,在維持傷害性感覺神經元的興奮性、動作電位的發放和持續以及痛覺敏感性的調節等方面,發揮著重要作用。NaV1.8激活性突變病人出現小纖維神經病變(主要負責痛覺傳遞的Aδ纖維和無髓纖維C型纖維受損)導致的陣發性疼痛。慢性炎症和糖尿病等疾病會引起NaV1.8表達增加或性質改變從而敏化傷害感受神經元,引起多種疼痛。而NaV1.8基因剔除小鼠對痛覺不敏感。
隨著Nav1.8在慢性疼痛中地位的確定,基於此靶點的藥物研究也日益火熱,目前國際上有一個小分子阻滯劑處於臨床2期,其他多個小分子阻滯劑及抗體在進行臨床前開發,國內尚無其他針對該靶點的新藥研發。處於研發前端的是美國福泰(Vertex)公司的小分子NaV1.8阻滯劑VX-150,目前已在骨性關節炎、急性疼痛及小纖維神經病變導致疼痛的患者中進行了2期臨床試驗,並且所有三項研究均獲得陽性結果,表明抑制NaV1.8活性可以緩解包括神經病理性疼痛在內的多種疼痛。目前VX-150獲得了美國FDA突破性療法認定,用於治療中度至重度疼痛,再次證明NaV1.8是鎮痛很有潛力的靶點。另外,NaV1.8 阻滯劑的作用機理及二期臨床實驗表明,其適應廣泛,包括神經病理性疼痛、骨關節炎疼痛和急性損傷疼痛等多種疼痛;且安全性相對高,沒有成癮性,也沒有非類固醇抗炎藥的胃腸道副作用及心腦血管方面的副作用;可以與其他鎮痛藥聯用,增強療效,降低副作用。
近年來還有研究表明鈉離子通道亞型1.8(NaV1.8)對咳嗽有一定的調控作用,NaV1.8 阻滯劑可能作為治療咳嗽的有潛力藥物。
本發明的發明人通過反覆的實驗研究,合理設計與合成了一系列如下列通式(I)表示的新型結構的小分子化合物,其具有很高鈉離子通道1.8(NaV1.8)阻滯活性。這些化合物或其立體異構體、外消旋物、幾何異構體、互變異構體、前藥、水合物、溶劑化物或其藥學上可接受的鹽及藥物組合物可用於治療或/和預防由NaV1.8介導的相關疾病。
本發明的化合物具有高的NaV1.8阻滯活性,為疼痛等疾病的治療提供了新的治療選擇。
本發明提供了式(Ⅰ)所示化合物、其光學異構體或其藥學上可接受的鹽,

相應地,本文所用的術語「雜芳環」指如上定義的雜芳基的環。
如本文所用,「芳基」、「芳族」遵循休克爾規則(Hückel's rule),其中π電子數等於4n
+2,n
為零或任何最多為6的正整數。
本文所用的術語「羰基」指基團–C(O)–,也可表示為-CO-。
本文所用的術語「胺基」指基團–NH2
。
本文所用的術語「任選」指隨後描述的事件可以發生或可以不發生,並且該描述包括所述事件發生的情形以及所述事件不發生的情形。例如,「任選被取代的烷基」指未取代的烷基和被取代的烷基,其中烷基如本文所定義。本領域具通常知識者應當理解,對於含有一個或多個取代基的任意基團而言,所述基團不包括任何在空間上不切實際的、化學上不正確的、合成上不可行的和/或內在不穩定的取代模式。
本文所用的術語「被取代的」或「被……取代」指給定原子或基團上的一個或多個氫原子被替換、例如被一個或多個選自給定取代基組的取代基替換,條件是不超過該給定原子的正常化合價。當取代基是氧代(即=O)時,則單個原子上的兩個氫原子被氧替換。只有當取代基和/或變量的組合導致化學上正確且穩定的化合物時,這類組合才是允許的。化學上正確且穩定的化合物意味著化合物足夠穩定,以至於能從反應混合物中被分離出來並能確定化合物的化學結構,並且隨後能被配製成至少具有實際效用的製劑。例如,在沒有明確列出取代基的情況下,本文所用的術語「被取代」或「取代」意指給定原子或基團上的一個或多個氫原子獨立地被一個或多個、例如1、2、3或4個取代基取代,所述取代基獨立地選自:氘(D)、鹵素、OH、巰基、氰基、-CD3

當任何變量(例如R)在化合物的組成或結構中出現一次以上時,其在每一種情況下的定義都是獨立的。因此,例如,如果一個基團被0-2個R所取代,則所述基團可以任選地至多被兩個R所取代,並且每種情況下的R都有獨立的選項。此外,取代基和/或其變體的組合只有在這樣的組合會產生穩定的化合物的情況下才是被允許的。
本文所用的術語「藥學上可接受的」指無毒的、生物學上可耐受的、適合給個體施用的。
本文所用的術語「藥學上可接受的鹽」指式(I)化合物的無毒的、生物學上可耐受的適合給個體施用的酸加成鹽或鹼加成鹽,包括但不限於:式(I)化合物與無機酸形成的酸加成鹽,例如鹽酸鹽、氫溴酸鹽、碳酸鹽、碳酸氫鹽、磷酸鹽、硫酸鹽、亞硫酸鹽、硝酸鹽等;以及式(I)化合物與有機酸形成的酸加成鹽,例如甲酸鹽、乙酸鹽、蘋果酸鹽、馬來酸鹽、富馬酸鹽、酒石酸鹽、琥珀酸鹽、檸檬酸鹽、乳酸鹽、甲磺酸鹽、對甲苯磺酸鹽、2-羥基乙磺酸鹽、苯甲酸鹽、水楊酸鹽、硬脂酸鹽和與式HOOC-(CH2
)n

此外,如果本文所述的化合物是以酸加成鹽的形式得到的,其游離鹼形式可以通過鹼化該酸加成鹽的溶液獲得。相反地,如果產物是游離鹼形式,則其酸加成鹽、特別是藥學上可接受的酸加成鹽可以按照由鹼性化合物製備酸加成鹽的常規操作通過將游離鹼溶於合適的溶劑並且用酸處理該溶液來得到。本領域具通常知識者無需過多實驗即可確定各種可用來製備無毒的藥學上可接受的酸加成鹽的合成方法。
本領域具通常知識者應當理解的是,一些式(I)化合物可以包含一個或多個手性中心,因此存在兩個或更多個立體異構體。因此,本發明的化合物可以以單個立體異構體(例如對映異構體、非對映異構體)及其任意比例的混合物例如外消旋物的形式存在,以及在適當的情況下,可以以其互變異構體和幾何異構體的形式存在。
本文所用的術語「立體異構體」指具有相同化學構成、但在原子或基團的空間排列方面不同的化合物。立體異構體包括對映異構體、非對映異構體和構象異構體等。
本文所用的術語「對映異構體」指化合物的彼此是不可重疊的鏡像的兩種立體異構體。
本文所用的術語「非對映異構體」指具有兩個或更多個手性中心並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。非對映異構體的混合物可以用高分辨率分析方法例如電泳和色譜例如HPLC分離。
立體化學定義和慣例可遵循S. P. Parker編輯, McGraw-Hill Dictionary of Chemical Terms (1984) McGraw-Hill Book Company, New York;和Eliel, E.和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,它們具有旋轉平面偏振光的平面的能力。在描述光學活性化合物時,前綴D和L或者R和S用於表示分子關於其手性中心的絕對構型。前綴d和l或者(+)和(-)用於表示化合物旋轉平面偏振光的符號,其中(-)或l表示該化合物是左旋的。帶有(+)或d的前綴的化合物是右旋的。對於給定的化學結構,除了它們彼此互為鏡像之外,這些立體異構體是相同的。特定的立體異構體也可以稱為對映異構體,這類異構體的混合物通常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物,其可以出現在化學反應或方法中沒有立體選擇性或立體特異性的情況中。術語「外消旋混合物」和「外消旋物」指不具有光學活性的兩種對映異構體的等摩爾混合物。
外消旋混合物可以以其本身的形式使用或者拆分成單個異構體使用。通過拆分可以得到立體化學上的純的化合物或者富集一種或多種異構體的混合物。分離異構體的方法是眾所周知的(參見Allinger N. L.和Eliel E. L.,"Topics in Stereochemistry"
,第6卷,Wiley Interscience,1971),包括物理方法,例如使用手性吸附劑的色譜法。可以由手性前體製備得到手性形式的單個異構體。或者,可以通過與手性酸(例如10-樟腦磺酸、樟腦酸、α-溴樟腦酸、酒石酸、二乙醯基酒石酸、蘋果酸、吡咯烷酮-5-羧酸等的單個對映異構體)形成非對映異構體鹽而由混合物化學分離得到單個異構體,將所述的鹽分級結晶,然後游離出拆分的鹼中的一個或兩個,任選地重複這一過程,從而得到一個或兩個基本上不包含另一種異構體的異構體,即光學純度以重量計為例如至少91%、92%、93%、94%、95%、96%、97%、98%、99%或99.5%的所需的立體異構體。或者,如本領域具通常知識者所熟知的,可以將外消旋物共價連接到手性化合物(輔助物)上,得到非對映異構體。
本文所用的術語「互變異構體」或「互變異構形式」指經由低能量障礙可相互轉化的不同能量的結構異構體。例如,質子互變異構體(也稱為質子轉移互變異構體)包括通過質子遷移進行的相互轉化,例如酮-烯醇和亞胺-烯胺異構化。價鍵互變異構體包括通過一些鍵合電子的重組進行的相互轉化。
本文所用的術語「治療」指給患有疾病或者具有所述疾病的症狀的個體施用一種或多種藥物物質、特別是本文所述的式(I)化合物和/或其藥學上可接受的鹽,用以治癒、緩解、減輕、改變、醫治、改善、改進或影響所述疾病或者所述疾病的症狀。本文所用的術語「預防」指給具有易患所述疾病的體質的個體施用一種或多種藥物物質、特別是本文所述的式(I)化合物和/或其藥學上可接受的鹽,用以防止個體罹患該疾病。當涉及化學反應時,術語「處理」、「接觸」和「反應」指在適當的條件下加入或混合兩種或更多種試劑,以產生所示的和/或所需的產物。應當理解的是,產生所示的和/或所需的產物的反應可能不一定直接來自最初加入的兩種試劑的組合,即,在混合物中可能存在生成的一個或多個中間體,這些中間體最終導致了所示的和/或所需的產物的形成。
本文所用的術語「有效量」指通常足以對個體產生有益效果的量。可以通過常規方法(例如建模、劑量遞增研究或臨床試驗)結合常規影響因素(例如給藥方式、化合物的藥代動力學、疾病的嚴重程度和病程、個體的病史、個體的健康狀況、個體對藥物的響應程度等)來確定本發明的化合物的有效量。
本文所用的未具體定義的技術和科學術語具有本發明所屬領域的具通常知識者通常理解的含義。

2. 給藥製劑的配製和分析
2.1 給藥製劑儲液配製方法
對照:稱量合適體積的DMSO作為儲液。
測試化合物:稱量合適質量的化合物(實際量=理論濃度*體積×分子量/純度),根據公式,計算出所需的DMSO的體積,然後換算出最終所需的DMSO的質量。之後將粉末用稱量的DMSO溶解。根據最終的DMSO使用量計算出實際的儲液濃度,一般地實際儲液濃度與理論濃度略有差異。
2.2 給藥製劑工作液配製方法及濃度
NaV通道電流測試之前,將對照和測試化合物儲液稀釋到10 mL細胞外液中作為工作液,並超聲20 min。
3. 實驗系統
3.1.細胞培養
1)穩定表達Nav1.8通道的CHO細胞系具體信息如下:SCN10A: NM_006514
2)細胞在含有10%胎牛血清以及10 µg/mL Blasticidin、200 µg/mL Hygromycin B及100 µg/mL Zeocin的HAM’S/F-12培養基中培養,培養溫度為37 ℃,二氧化碳濃度為5%。

4.2. 膜片鉗檢測
全細胞膜片鉗記錄Nav通道電流的電壓刺激方案如下:首先將細胞的膜電位鉗制在-130mV, 然後以10mv的階躍間隔,將電壓階躍至-40mV或者-20mV,持續8s。鉗制電壓維持在-120mV,每隔20秒重複採集數據。測量其內向電流的峰值振幅,確定其半失活電壓。
細胞鉗制電位設定在-120mV。鈉電流的靜息和半失活抑制使用雙脈衝模式來測量。雙脈衝模式由兩個持續50ms的0mV去極化測試脈(TP1以及TP2)完成。兩個去極化脈衝之間的條件電壓,設定在半失活電壓附近(持續8s)。在給與第二個去極化脈衝之前,將細胞膜電位鉗制到-120mv,持續20ms以使得未結合化合物,且處於失活狀態的通道得到恢復。以20s的間隔重複採集數據,並測量兩個測試脈衝處的電流峰值。
實驗數據由EPC-10 放大器(HEKA)進行採集並儲存於PatchMaster(HEKA)軟件中(軟件版本:v2x73.2)。
用微電極拉制儀(P97,Sutter Instruments)將毛細玻璃管(BF150-86-10,Sutter Instruments)拉制成記錄電極。在倒置顯微鏡(IX71)下操縱微電極操縱儀(MP285)將記錄電極接觸到細胞上,給予負壓抽吸,形成GΩ封接。形成GΩ封接後進行快速電容補償,然後繼續給予負壓,吸破細胞膜,形成全細胞記錄模式。然後進行慢速電容的補償並記錄膜電容及串聯電阻,不給予漏電補償。
當全細胞記錄的Nav通道電流穩定後開始給藥,每個藥物濃度作用至5分鐘(或者電流至穩定)後檢測下一個濃度,每一個測試化合物檢測多個濃度。將鋪有細胞的蓋玻片置於倒置顯微中的記錄浴槽中,測試化合物以及不含化合物的外液利用重力灌流的方法從低濃度到高濃度依次流經記錄小室從而作用於細胞,在記錄中利用真空泵進行液體交換。每一個細胞在不含化合物的外液中檢測到的電流作為自己的對照組。獨立重複檢測多個細胞。所有電生理實驗在室溫下進行。
4.3. 數據分析
首先將每一個藥物濃度作用後的電流和空白對照電流標準化,然後計算每一個藥物濃度對應的阻滯率。對每一個濃度計算平均數和標準誤差,以上所有數值利用Microsoft Excel 2013計算獲得。此外通過IGOR軟件運用以下的方程計算每種化合物的半抑制濃度:阻滯率=1/﹝1+(IC50
/c)h
﹞。
用以上方程對劑量依賴效應進行非線性擬合,其中c代表藥物濃度,IC50
為半抑制濃度,h代表希爾係數。曲線擬合以及IC50
的計算利用IGOR軟件完成(軟件版本:6.0.1.0)。

二.本發明化合物的藥代動力學實驗結果
本實驗例對大鼠通過單次靜脈注射或灌胃口服給藥進行了體內藥代動力學評價。
實驗方法和條件:雄性Sprague Dawley大鼠,動物均禁食過夜,分別單次給予待測化合物1 mg/Kg (靜脈注射,溶劑5%DMSO/10%Solutol/85%Saline)和10 mg/Kg (灌胃給藥),給藥後 5, 15, 30 min, 1, 2, 4, 6, 8和24 hr經頜下靜脈采血,每個樣品採集約0.20 mL,肝素鈉抗凝,採集後放置冰上,並於1小時之內離心分離血漿待測。血漿中血藥濃度的檢測採用液相串聯質譜法(LC/MS/MS),測得濃度用以計算藥代動力學參數。結果如下表6和表7所示。
表 6:靜脈給藥(1 mg/kg)的藥代動力學
表 7:灌胃注射給藥(10 mg/kg)的藥代動力學
可見本公開化合物在大鼠內藥代吸收良好,具有藥代動力學優勢。
