【摘要】：近年來腫瘤的靶點(diǎn)治療方法得到了越來越多的發(fā)展,特別是多靶點(diǎn)藥物,由于優(yōu)越的藥理活性在臨床上應(yīng)用廣泛。SR是一種口服多激酶抑制劑,一方面SR可抑制EGFR、VEGFR,發(fā)揮抗血管生成作用;另一方面抑制Raf信號(hào)通路,從而抗細(xì)胞增殖。目前在各國藥典中尚未收載其質(zhì)量標(biāo)準(zhǔn),該課題采用多種分析技術(shù)對(duì)SR原料藥進(jìn)行質(zhì)量標(biāo)準(zhǔn)研究,并對(duì)各研究方法進(jìn)行方法學(xué)驗(yàn)證,以制定出SR的質(zhì)量標(biāo)準(zhǔn)草案。首先,該課題對(duì)SR的理化性質(zhì),包括性狀、溶解度、熔點(diǎn)等項(xiàng)目進(jìn)行了考察,建立了快速準(zhǔn)確的實(shí)驗(yàn)方法。其次,本文對(duì)SR原料藥進(jìn)行了有關(guān)物質(zhì),包括基因毒性雜質(zhì)檢查的方法開發(fā)和方法學(xué)研究,通過考察色譜柱、流動(dòng)相、稀釋劑和流速、柱溫等因素,分別建立了測(cè)定有關(guān)物質(zhì)、檢查基因毒性雜質(zhì)的液相色譜條件。其中有關(guān)物質(zhì)的測(cè)定方法為:Waters e2695系統(tǒng),2489 UV檢測(cè)器,色譜柱為Waters C18 Symmetry Shield~(TM)(5μm,4.6×150mm)色譜柱,流動(dòng)相有機(jī)相為乙腈,水相為0.01 mol/L NaH_2PO_4溶液(稀磷酸調(diào)節(jié)pH至3.0),檢測(cè)波長為265 nm,柱溫為40℃,流速為1.0 ml/min,進(jìn)樣量為10 μL,并對(duì)該方法進(jìn)行了方法學(xué)驗(yàn)證,結(jié)果表明該方法能快速準(zhǔn)確檢測(cè)SR的有關(guān)物質(zhì)。三批樣品的有關(guān)物質(zhì)均小于0.1%。再次,本文采用氣相色譜法建立了SR殘留溶劑的檢測(cè)方法。最佳的色譜條件為氣相色譜儀為Agilent 7890A,直接進(jìn)樣器為Agilent G4513A,使用Agilent DB毛細(xì)管柱和FID檢測(cè)器,檢測(cè)器溫度為250℃,柱溫為程序升溫,起始溫度40℃維持11分鐘,以每分鐘10℃的升溫速率升至130℃,維持12分鐘,再以每分鐘100℃的升溫速率升至200℃,維持20 min。載氣為高純氮?dú)?直接進(jìn)樣氣化室溫度為220℃,進(jìn)樣量為2 μL,對(duì)該方法進(jìn)行了方法學(xué)驗(yàn)證。驗(yàn)證結(jié)果表明該方法線性良好,靈敏度高,重復(fù)性好。以內(nèi)標(biāo)法對(duì)三批樣品進(jìn)行檢測(cè),乙醇的檢出量小于標(biāo)準(zhǔn)限度,其他溶劑未檢出。同時(shí)對(duì)有關(guān)物質(zhì)液相色譜方法的色譜條件稍作調(diào)整,建立SR原料藥的含量測(cè)定方法,并進(jìn)行方法學(xué)驗(yàn)證,結(jié)果表明該方法可以準(zhǔn)確測(cè)定SR的含量。對(duì)SR三批樣品進(jìn)行測(cè)定,結(jié)果表明三批樣品的含量均在98%-102%之間。最后,建立了測(cè)定對(duì)甲苯磺酸成鹽比例的液相色譜方法,并對(duì)其進(jìn)行方法學(xué)驗(yàn)證。驗(yàn)證結(jié)果表明該方法可用于檢測(cè)對(duì)甲苯磺酸的成鹽比例。對(duì)SR原料藥的水分、干燥失重、熾灼殘?jiān)椭亟饘贆z查等項(xiàng)目進(jìn)行檢查,三批樣品的測(cè)定結(jié)果均符合要求。使用紅外光譜和液相色譜對(duì)SR原料藥進(jìn)行鑒別。對(duì)SR原料藥的穩(wěn)定性進(jìn)行考察,主要進(jìn)行影響因素試驗(yàn),結(jié)果表明,SR原料藥對(duì)強(qiáng)光、高濕和高溫都比較穩(wěn)定,性狀、含量和有關(guān)物質(zhì)無明顯變化。上述實(shí)驗(yàn)為SR原料藥的質(zhì)量標(biāo)準(zhǔn)草案提供了依據(jù),并為制劑工藝的研發(fā)和生產(chǎn)工藝的設(shè)計(jì)奠定了基礎(chǔ)。
[Abstract]:In recent years, the target therapy of tumor has been more and more developed, especially multi-target drugs. Because of its excellent pharmacological activity, SR is a kind of oral polykinase inhibitor, which is widely used in clinic.On the one hand, SR can inhibit EGFR and exert anti-angiogenesis effect; on the other hand, SR can inhibit Raf signaling pathway and thus inhibit cell proliferation.At present, the quality standard of SR has not been collected in the pharmacopoeia of various countries. This paper studies the quality standard of SR API by using various analytical techniques, and verifies the methodology of each research method in order to work out the draft of SR quality standard.Firstly, the physical and chemical properties of SR, including properties, solubility and melting point, were investigated, and a rapid and accurate experimental method was established.Secondly, the related substances, including the method and methodology of genotoxic impurity detection, were developed and studied. The related substances were determined by investigating the chromatographic column, mobile phase, diluent and flow rate, column temperature, etc.The liquid chromatographic conditions of toxic impurities were examined.The flow rate was 1.0 ml / min and the injection amount was 10 渭 L. the results showed that the method could be used to detect SR related substances quickly and accurately.The related substances of the three batches of samples are less than 0.1.Thirdly, gas chromatography was used to establish a method for the determination of SR residual solvent.The best chromatographic conditions were Agilent 7890A, Agilent G4513A, Agilent DB capillary column and FID detector. The detector temperature was 250 鈩，
