本發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,屬藥物化學領域。
背景技術:
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異常有著良好的抑制作用和鎮痛作用,而且還具有清除自由基、抗腫瘤、抗病毒、抗氧化、抗突變、抗菌和調節免疫等方面的功能(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構,分子間排列緊密,使大多數黃酮類天然產物水溶性或脂溶性較低,導致其生理活性利用率不高,限制了黃酮類天然產物的開發和應用(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展[j].有機化學,2008,28(9),1534-1544)。改性的方法主要有取代反應、mannich反應、酯化反應、羥基化反應和糖基化反應等。例如用不同碳鏈長的二溴烷烴與白楊素7-oh位發生親電取代反應,引入活性基團后與嗎啡啉、n-甲基哌嗪、哌嗪、n,n-二甲基胺氨解反應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合成了具有哌嗪取代基的黃酮類衍生物,體內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,選擇性合成了異槲皮苷-6”-o-酯基衍生物。其酯化產物脂溶性、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羥基發生酯化反應,合成的黃酮氨基磷酸酯衍生物經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計與合成[d].大連,大連理工大學,2012);modolo等通過糖基轉移酶催化了黃酮和異黃酮進行糖基化反應。(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、廣泛的液態范圍、高離子電導性、高熱穩定性和可溶解大多數化合物等良好的性質,被廣泛應用于有機合成中。近年來,離子液體作為溶劑,用于天然產物的改性也有報道,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酰化反應,離子液體的使用大大提高了反應轉化率和酶的區域選擇性(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。相對于文獻報道的化學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體系,不僅能大大節省催化劑的用量,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體系也為黃酮類化合物的結構修飾提供一條新的途徑。
