      文檔序號:11245014閱讀:1184來源:國知局

      本發(fā)明涉及黃酮類化合物,尤其涉及曲克蘆丁酰胺類化合物及其制備方法和用途,屬藥物化學(xué)領(lǐng)域。



      背景技術(shù):

      黃酮是一種多酚類化合物,廣泛存在于高等植物的根、莖、葉、花、果實中,這類化合物不僅對心腦血管以及消化系統(tǒng)異常有著良好的抑制作用和鎮(zhèn)痛作用,而且還具有清除自由基、抗腫瘤、抗病毒、抗氧化、抗突變、抗菌和調(diào)節(jié)免疫等方面的功能(harborne,jb;williams,ca.advancesinflavonoidresearchsince1992[j].phytochemistry,2000,55,481-504;劉星雨,孫體健,周敏.天然黃酮類化合物的藥理活性及分離提取[j].中國藥物與臨床,2014,14(5),621-624)。但由于其剛性平面結(jié)構(gòu),分子間排列緊密,使大多數(shù)黃酮類天然產(chǎn)物水溶性或脂溶性較低,導(dǎo)致其生理活性利用率不高,限制了黃酮類天然產(chǎn)物的開發(fā)和應(yīng)用(延璽,劉會青,鄒永青,等.黃酮類化合物生理活性及合成研究進(jìn)展[j].有機(jī)化學(xué),2008,28(9),1534-1544)。改性的方法主要有取代反應(yīng)、mannich反應(yīng)、酯化反應(yīng)、羥基化反應(yīng)和糖基化反應(yīng)等。例如用不同碳鏈長的二溴烷烴與白楊素7-oh位發(fā)生親電取代反應(yīng),引入活性基團(tuán)后與嗎啡啉、n-甲基哌嗪、哌嗪、n,n-二甲基胺氨解反應(yīng)合成新型白楊素的含氮衍生物(sureshbabuk,haribabut,srinivaspv,etal.synthesisandbiologicalevaluationofnovelc(7)modifiedchrysinanaloguesasantibacterialagents[j].bioorg.med.chem.lett.,2006,16,221-224)。zeng等同樣利用親電取代反應(yīng)合成了具有哌嗪取代基的黃酮類衍生物,體內(nèi)體外顯示了抗腫瘤性(zengs,liuw,nieff,etal.lyg-202,anewflavonoidwithapiperazinesubstitution,showsantitumoreffectsinvivoandinvitro[j].biochem.bioph.res.co.,2009,385,551-556);babu等通過mannich反應(yīng)用甲醛和一級、二級胺與木蝴蝶素合成了一系列的8-胺甲基衍生物(babuth,ramasubbaraov,ashokk,etal.synthesisandbiologicalevaluationofnovel8-aminomethylatedoroxylinaanaloguesasa-glucosidaseinhibitors[j].bioorg.med.chem.let,2008,18,1659-1662);bhullar等在丙酮和叔戊醇中,以novozym435催化異槲皮苷與脂肪酸的酯化反應(yīng),選擇性合成了異槲皮苷-6”-o-酯基衍生物。其酯化產(chǎn)物脂溶性、抗氧化性、抗增殖活性都有了很大的提高(ziaullah;bhullar,khushwants.;warnakulasuriya,sumudun.etal.bhullarks,warnakulasuriyasn,rupasinghehv.biocatalyticsynthesis,structuralelucidation,antioxidantcapacityandtyrosinaseinhibitionactivityoflongchainfattyacidacylatedderivativesofphloridzinandisoquercitrin[j].bioorg.med.chem.let,2013,21(3):684-692)。韓天佼以6種黃酮(白楊素,芹菜素,大豆苷元等)為原料,與氨基磷酸酯在黃酮c-7羥基發(fā)生酯化反應(yīng),合成的黃酮氨基磷酸酯衍生物經(jīng)hiv活性評價,可能具有抗腫瘤活性(韓天佼,六種黃酮7位氨基磷酸醋衍生物的設(shè)計與合成[d].大連,大連理工大學(xué),2012);modolo等通過糖基轉(zhuǎn)移酶催化了黃酮和異黃酮進(jìn)行糖基化反應(yīng)。(modololv,lil,panh,etal.crystalstructuresofglycosyltransferaseugt78g1revealthemolecularbasisforglycosylationanddeglycosylationof(iso)flavonoids[j].j.mol.biology,2009,392(5):1292-1302)。

      離子液體作為一種綠色溶劑,因具有低蒸氣壓、廣泛的液態(tài)范圍、高離子電導(dǎo)性、高熱穩(wěn)定性和可溶解大多數(shù)化合物等良好的性質(zhì),被廣泛應(yīng)用于有機(jī)合成中。近年來,離子液體作為溶劑,用于天然產(chǎn)物的改性也有報道,例如katsoura等研究了酶在離子液體[bmim][bf4]做溶劑時催化蘆丁和柚皮苷?;磻?yīng),離子液體的使用大大提高了反應(yīng)轉(zhuǎn)化率和酶的區(qū)域選擇性(katsouramh,polyderaac,tsironisl,etal.useofionicliquidsasmediaforthebiocatalyticpreparationofflavonoidderivativeswithantioxidantpotency[j].j.biotechnol.,2006,123(4):491-503)。wang報道了離子液體與緩沖溶劑作為共溶劑,有利于酶通過選擇性地水解蘆丁,轉(zhuǎn)化得到異槲皮苷(wang,j,sun,gx,yu,letal.enhancementoftheselectiveenzymaticbiotransformationofrutintoisoquercitrinusinganionicliquidasaco-solvent[j].biores.technol.2012,128:156-163)。用離子液體催化合成曲克蘆丁酰胺類衍生物未見報道。相對于文獻(xiàn)報道的化學(xué)催化和酶催化改性黃酮類化合物而言,以離子液體既做溶劑、又作為催化劑的反應(yīng)體系,不僅能大大節(jié)省催化劑的用量,而且因離子液體制備簡單,價格較低,容易回收等特點,可降低合成成本,簡化后處理操作。用價廉的離子液體作為催化劑的反應(yīng)體系也為黃酮類化合物的結(jié)構(gòu)修飾提供一條新的途徑。

      (2)r1=och3,r2=och3,n為4,8,

      (3)r1=h,r2=och3,n為3,5,7。

      上述化合物合成路線如下:

      n-(4-氟)苯乙基/芐基曲克蘆丁酰胺衍生物(ⅰ)其合成方法通過如下方式實現(xiàn):

      曲克蘆丁與脂肪酸二乙烯酯在枯草桿菌蛋白酶催化下,以吡啶為反應(yīng)介質(zhì),40℃~60℃反應(yīng),反應(yīng)結(jié)束后,過柱分離得到曲克蘆丁乙烯酯。

      曲克蘆丁乙烯酯:胺類化合物摩爾比為1:2~10。

      含四氫異喹啉曲克蘆丁酰胺類衍生物(ⅱ)其合成方法通過如下方式實現(xiàn):

      離子液體做反應(yīng)介質(zhì),曲克蘆丁乙烯酯與1,2,3,4-四氫異喹啉類化合物為反應(yīng)底物,在40~70℃反應(yīng)。反應(yīng)結(jié)束后,有機(jī)溶劑萃取產(chǎn)物,濃縮后,柱色譜分離,得到含四氫異喹啉曲克蘆丁酰胺類衍生物(ⅱ)。

      本發(fā)明優(yōu)點:以離子液體既做溶劑、又作為催化劑的反應(yīng)體系,無需額外添加催化劑、合成產(chǎn)率高,達(dá)70%以上,反應(yīng)工藝簡單、操作簡便,反應(yīng)條件溫和,后處理容易,離子液體容易回收、成本較低;同時,生成的產(chǎn)物具有抗腫瘤活性,對結(jié)腸癌和乳腺癌有較好的抑制活性,具有較好的開發(fā)應(yīng)用價值。

      生物活性測試:采用mtt法測定了曲克蘆丁及化合物(ⅰ)和(ⅱ)對ht-29(人結(jié)腸癌細(xì)胞),mcf-7(人乳腺癌細(xì)胞)的細(xì)胞毒活性。

      部分測試結(jié)果如下表:

      以上數(shù)據(jù)顯示了化合物(ⅰ)和(ⅱ)對ht-29、mcf-7有明顯的抑制作用,優(yōu)于曲克蘆丁,可將其作為抗結(jié)腸癌和乳腺癌潛在藥物開發(fā)。
