Description
本發明屬於化學製藥領域,具體涉及一種苯基胺基丙酸鈉衍生物,本發明還涉及所述苯基胺基丙酸鈉衍生物的製備方法以及其用作西格列他或其衍生物藥物中的原料藥或製劑的品質控制的用途;特別地,所述苯基胺基丙酸鈉衍生物可以用作西格列他或其鹽(例如鈉鹽)的原料藥或製劑中雜質或有關物質檢查的對照品或標準品。
在中國專利申請CN03126974.5和美國專利申請US7,268,157中均記載了該化合物的藥理活性。西格列他具有選擇性啟動PPAR-α、PPAR-γ和PPAR-δ的能力,可以用於治療與代謝綜合症相關的疾病,如糖尿病、高血壓、肥胖、胰島素抵抗、高甘油三酯血症、高血糖、
高膽固醇、動脈粥樣硬化、冠心病等。
在現有技術中,中國專利申請201610855107.3和中國專利申請201410856282.5中公開了西格列他及其鈉鹽的合成方法。
該方法適合工業化生產,所得目標化合物純度高。然而,由於西格列他的穩定性較差,在藥物製造、貯存和運輸過程中易分解,嚴重影響了該藥物的安全性和有效性,因此,需將其製成穩定性更好的鈉鹽,即西格列他鈉。在中國專利申請201410856282.5中公開了西格列他鈉的製備方法,所述方法如下:
按照上述現有技術中的製備方法,可以製得純度大於99%的西格列他鈉,且工藝穩定可控,適合工業化生產。然而,本發明人通過大量研究意外地發現,HPLC分析(色譜柱:C18柱,Shim-pack VP-ODS 5μm 250L×4.6;流動相:甲醇-水-四氫呋喃-醋酸40:30:30:0.5;檢測波長:236nm;流速:1.5mL/min)表明,在相對保留值約2.4處始終有一未知結構雜質,該雜質隨原料1和原料2的用量相對比例變化在一定範圍內波動。當原料1與原料2的比例為1:1時,該雜質含量約為0.18%(面積歸一化法);當原料1與原料2的比例為1:1.5時,該雜質含量約為0.06%(面積歸一化法)。由於現有技術中一直未公開和報導該雜質的存在及其結構,其藥理毒理性質也是未知的,因此給安全用藥帶來風險。同時,由於該雜質結構未知,且現有技術也未公開報導西格列他鈉的任何雜質資訊及分離方法,這給該雜質的分離和鑒定帶來極大困難。
一方面,為了保證患者的用藥安全,需要確認該未知雜質的結構;另一方面,需要研究該雜質化合物的製備方法,獲得其對照品或參比標準品,用於西格列他或西格列他鈉等藥物的品質控制,尤其是用作有關物質/雜質檢查的對照品或參比標準品。
基於現有技術中的上述需要,本發明的目的之一在於公開現有技術工藝製得的西格列他或西格列他鈉鹽等藥物中存在的上述未知結構化合物。
本發明人研究發現,該雜質為3-(4-(2-(9H-咔唑-9-基)乙氧基)苯基)-2-((2-(4-(4-(2-甲酸鈉-2-((2-(4-氟苯甲醯基)苯基)胺基)乙基)苯氧基)苯
甲醯基)苯基)胺基)丙酸鈉,其結構如式(I)所示:
事實上,上述式(I)化合物的產生並不局限於上述製備西格列他鈉的反應途徑,其同樣可存在於西格列他的合成產物中。
需要指出的是,上述反應路線中所用的反應溶劑和鹼均是示例性的而不是限定性的,本領域技術人員可以進行適當的變換和調整。
在示例性的實施方案中,使化合物(a)與化合物(b)進行縮合反應得到化合物(c)。該反應可以以碳酸銫為催化劑,優選以N,N-二甲基甲醯胺為溶劑,反應溫度可以為80~120℃,反應時間可為20~30小時。所得粗產品可未經進一步純化,直接用於下一步反應。
將化合物(c)酸化得到化合物(d)。所述酸化優選用鹽酸進行。該反應優選以乙酸乙酯和水為溶劑,反應溫度可以為室溫,反應時間可為4~5小時。所得粗產品可以未經進一步純化,直接用於下一步反應。
將化合物(d)在氫氧化鋰存在下進行水解得到化合物(e)。
該反應優選以四氫呋喃和水為溶劑,反應溫度可以為室溫,反應時間可為12~16小時。所得粗產品可以未經進一步純化,直接用於下一步反應。
將化合物(e)酸化得到合物(f)。所述酸化優選用鹽酸進行。該反應優選以乙酸乙酯和水為溶劑,反應溫度可以為室溫,反應時間可為4~5小時。在一個示例性的實施方案中,所得粗產品用半製備液相色譜柱分離(色譜柱:YMC-Pack ODS-AQ 5μm 250L×20;流動相:甲醇-水-四氫呋喃-冰醋酸48:22:30:0.5;檢測波長:236nm;流速:8ml/min),得到純度大於97%的化合物(f)。
將化合物(f)用氫氧化鈉中和得到式(I)化合物。該反應可以以甲醇為溶劑,反應溫度可為室溫,反應時間可為20~40min。
在另一方面,本發明還提供了式(I)化合物用於西格列他或其衍生物的原料藥或製劑的品質控制的用途。特別地,本發明提供了式(I)化合物作為西格列他或西格列他鈉藥物中雜質或有關物質檢查的對照品或標準品的用途。
作為對照品或標準品。
優選地,上述檢測方法優選HPLC方法。
在本發明的一個示例性實施方案中,所述HPLC法的條件如下:色譜柱:C18柱,Shim-pack VP-ODS 5μm 250L×4.6;流動相:甲醇-水-四氫呋喃-醋酸40:30:30:0.5;檢測波長:236nm;流速:1.5mL/min)。
以式(I)化合物作對照品,在西格列他鈉樣品溶液中加入適量式(I)化合物,記錄色譜圖,確認式(I)化合物就是相對保留值約2.4的雜質。分別記錄西格列他鈉樣品溶液和式(I)化合物標準品溶液的色譜圖,採用外標法計算西格列他鈉藥物中式(I)化合物的含量。
本發明的上述HPLC檢測方法的優點是測定結果準確可靠,專屬性強,實用性強,可以有效檢出上述雜質,且所述雜質與西格列他或其鹽之間達到良好分離。
雜質研究是藥品研發的重要內容,貫穿於藥品研發的始終,直接影響到藥物的品質和安全性。為了給西格列他或其衍生物的品質研究提供有關物質對照品,提高西格列他或其衍生物、以及含有西格列他或其衍生物的組合物(包括藥物製劑)的品質標準,為安全用藥提供重要的指導,本發明研究、合成並鑒定了所述工藝雜質。
下面結合實施例進一步闡明本發明的內容,但本發明的保護
範圍並不僅僅局限於這些實施例。本發明所述的百分比除特別注明外,均為重量百分比。說明書中所描述的數值範圍,如計量單位或百分比,均是為了提供明白無誤的書面參考。本領域熟練技術人員在實踐本專利時,基於本發明的教導和原則,使用在此範圍之外或有別於單個數值的溫度、濃度、數量等,仍然可以得到預期的結果。
術語與定義:
“衍生物”:在本發明中,西格列他衍生物不僅包括西格列他游離酸,還包括其鹽,例如無機鹽,例如鈉鹽,以及其水合物。
“雜質”與“相對保留值”:任何影響藥物純度的物質均稱為雜質,一般而言,雜質是指在生產和儲存過程中引進或產生的活性藥物物質以外的其他化學物質。本領域技術人員公知,可以利用光譜方法和通過其它物理方法識別次要產物、副產物和附加試劑(總稱為“雜質”),於是雜質與色譜中的峰位置(或薄層色譜板上的斑點)有關(Strobel,H.A.;Heineman,W.R.,Chemical Instrumentation:Asystematic Approach,3rd.(Wiley&Sons:New York1989))。此後,雜質可以通過其在所述色譜中的位置被識別出來,色譜中的位置通常用樣品注射到柱上和特定的組分經檢測器流出之間的時間以分鐘計算,被稱為“保留時間”。這一時間段基於使用儀器的條件和許多其它因素每天變化。為減輕這樣變化對雜質準確鑒別的影響,專業人員使用“相對保留時間”(或相對保留值)來鑒別雜質。雜質的相對保留值是其保留時間除以參考標記物(例如對照品或參比標準品)的保留時間的比值。
“對照品”與“標準品”:製藥領域的研發人員都知道,相當純
態的化合物可用作“標準品”或“對照品”。對照品一般系指用於鑒別、檢查、含量測定和校正檢定儀器性能的標準物質,而標準品系通常指用於生物檢定、抗生素或生物藥品中含量或效價測定的標準物質。本發明中對二者不做嚴格區分。標準品可用於定性分析,也用於定量測定未知混合物中待檢測化合物的含量。在採用相同技術分析已知濃度的標準品的溶液以及未知混合物時,標準品是“外標物”。化合物在混合物中的含量可以通過比較檢測器回應值大小來測定。同樣也可參見美國專利6,333,198,其內容在此引作參考。如果補償檢測器對兩個化合物的敏感度差異的“回應因數”已經預先確定,則標準品也可以用於測量混合物中另一化合物的含量。為此,將標準物直接加到混合物中,其被稱為“內標物”。在不特意加入標準品而是利用稱作“標準品加入”的技術使未知混合物包含可檢測量的參比標準品時,則標準品可用作內標物。
