本發(fā)明涉及一類新型的喹唑啉衍生物及其鹽和其溶劑化物;并涉及該類化合物的制備方法和它們在制備抗腫瘤藥物方面的用途。
背景技術(shù):
臨床上常用的抗腫瘤藥物主要是細(xì)胞毒類藥物,具有難以避免的毒副作用。近來興起的靶向腫瘤治療給腫瘤患者帶來福音。靶向腫瘤治療藥物進(jìn)入體內(nèi)能特異性地與致癌靶標(biāo)相結(jié)合而發(fā)揮作用,使腫瘤細(xì)胞特異性死亡,而不會波及周圍的正常細(xì)胞。表皮生長因子受體是一種受體酪氨酸激酶,研究表明表皮因子生長受體(egfr)是一個治療癌癥的重要靶點(diǎn)。隨著人們對egfr信號轉(zhuǎn)導(dǎo)通路的認(rèn)知,現(xiàn)階段已經(jīng)開發(fā)出了一些靶向egfr的藥物,包括單克隆抗體、小分子酪氨酸激酶抑制劑,反義寡核苷酸、抗霉素軛合物等。其中小分子酪氨酸激酶抑制劑是最具潛力且應(yīng)用最為廣泛的egfr抑制劑。
喹唑啉類化合物作為一種有效的egfr抑制劑(tki),受到了普遍的重視。4-苯氨基喹唑啉是一類較早發(fā)現(xiàn)的表皮生長因子受體酪氨酸激酶的抑制劑。一系列的報(bào)道表明4-苯氨基喹唑啉化合物通過與egfr的atp結(jié)合位點(diǎn)結(jié)合,高度選擇性地抑制egfr的磷酸化,進(jìn)而達(dá)到抑制腫瘤細(xì)胞增殖的效果。目前egfr酪氨酸抑制劑已經(jīng)發(fā)展到第三代。這些egfr抑制劑與egfr的作用方式可分為兩種,即可逆型和不可逆型抑制劑。第一代為可逆型抑制劑以gefitinib、erlotinib、icotinib(liud,zhangl,wuy,etal.lungcancer,2015,89(3):262-267.)等為代表。這些第一代egfr抑制劑在腫瘤治療的過程中,產(chǎn)生egfr的t790m突變會對第一代egfr抑制劑產(chǎn)生耐藥性。t790m突變是由蘇氨酸t(yī)hr790變成體積更大的蛋氨酸met790,改變了egfr激酶域的構(gòu)象,增強(qiáng)了atp與egfr激酶口袋的結(jié)合能力,大大降低了egfrtkis的結(jié)合能力(susumuk,boggontj,tajhald,etal.newenglandjournalofmedicine,2005,352(8):786-792.)。針對這種突變,藥物化學(xué)家開發(fā)出了第二代不可逆型egfrtkis。作為不可逆型egfrtkis,這些藥物包含了一個michael受體,與位于atp結(jié)合口袋入口處的半胱氨酸殘基(cys797)發(fā)生共價(jià)鍵結(jié)合,產(chǎn)生不可逆抑制酪氨酸激酶的活性作用(changs,zhangl,xus,etal.journalofmedicinalchemistry,2012,55(6):2711-2723.)。第二代不可逆egfr抑制劑中以afatinib(dungort,keatinggm.drug,2013,73(13):1503-1515.)、dacomitinib、neratinib(hwei-rut,etal.journalofmedicinalchemistry,2005,48(4):1107-1131.)為代表,雖然它們在治療t790m突變的非小細(xì)胞肺癌有較好的療效,但其與劑量相關(guān)的副作用較為嚴(yán)重,如腹瀉,皮疹等(wenjunz,daliae,liangc,etal.nature,2009,462(7276):1070-1074.)?;谝陨显?,第三代egfrtkis便應(yīng)運(yùn)而生,如co-1686及azd9291等。盡管第三代egfrtkis的臨床研究展現(xiàn)出高的活性,但接受azd9291治療的患者有將近三分之一出現(xiàn)了一種新的突變egfrc797s突變(第三次點(diǎn)突變)。這種新出現(xiàn)的egfrc797s突變對第三代egfrtkis產(chǎn)生了新的耐藥性(zopiap,etal.cancerdiscovery,2015,5(7):713-722.),因此,開發(fā)新型高效的egfrtkis具有極其重要的意義。

mtt(mpbio)、96孔細(xì)胞培養(yǎng)板(costar)、胎牛血清(gibco)、培養(yǎng)基(gibco)、酶標(biāo)儀(perkinelmerenspire)。
3、實(shí)驗(yàn)步驟
化合物1~28對腫瘤細(xì)胞的生長抑制活性利用mtt法進(jìn)行測定。分別取對數(shù)生長期的人腫瘤細(xì)胞sw480、a549、a431、nci-h1975,用0.25%的胰蛋白酶消化液消化、離心、重懸后計(jì)數(shù),制備細(xì)胞懸液,調(diào)整細(xì)胞懸液濃度為2×104~5×104個/ml。取細(xì)胞懸液接種于96孔細(xì)胞培養(yǎng)板中(100μl/孔),置飽和濕度、37℃和5%co2培養(yǎng)箱中培養(yǎng)24h。用培養(yǎng)基稀釋受試化合物至所需濃度,加入已接種人腫瘤細(xì)胞的96孔細(xì)胞培養(yǎng)板中(100μl/孔),dmso終濃度為0.5%,置于培養(yǎng)箱中培養(yǎng)72h。將mtt加入96孔板中(20μl/孔),培養(yǎng)箱中反應(yīng)4h。吸棄孔內(nèi)液體,加入dmso(150μl/孔),搖床上震蕩10min,使甲臜完全溶解。然后用酶標(biāo)儀測定570nm波長處的吸光度(od570),630nm波長處的吸光度(od630)作為參比,以相應(yīng)溶劑作為對照,計(jì)算細(xì)胞生長抑制率。
受試化合物對腫瘤細(xì)胞生長抑制率的計(jì)算方式如下:
腫瘤細(xì)胞生長抑制率%=[1-(ods-odnc)/(odpc-odnc)]×100%
其中:ods表示樣品孔的吸光度值(細(xì)胞+待測化合物+mtt);odpc表示對照孔的吸光度值(細(xì)胞+dmso+mtt);odnc表示調(diào)零孔的吸光度值(培養(yǎng)基+dmso+mtt);ods=od570s-od630s;odpc=od570pc-od630pc;odnc=od570nc-od630nc。
受試化合物對腫瘤細(xì)胞生長抑制曲線的擬合及ic50的計(jì)算:
采用graphpadprism5擬合受試化合物對腫瘤細(xì)胞生長的抑制曲線,并得出ic50值。每組設(shè)置3個復(fù)孔,實(shí)驗(yàn)至少重復(fù)3次。
4、實(shí)驗(yàn)結(jié)果
以臨床使用的抗腫瘤藥物吉非替尼(gefitinib)和拉帕替尼(lapatinib)為陽性對照,實(shí)驗(yàn)結(jié)果如表1所示。
表1受試化合物抑制腫瘤細(xì)胞增殖的ic50(μmol/l)
由表1中實(shí)驗(yàn)數(shù)據(jù)可見,大部分受試化合物對5種腫瘤細(xì)胞株的增殖都具有很好的抑制作用,其中一些化合物的效果明顯優(yōu)于臨床抗腫瘤藥物gefitinib和lapatinib。
