本發(fā)明涉及天然藥物及藥物化學(xué)領(lǐng)域,具體涉及一類新型的A環(huán)改造的冬凌草甲素14位羥基衍生物。本發(fā)明還公開了這些A-環(huán)改造冬凌草甲素14位衍生物的制備方法及其在治療腫瘤疾病中的應(yīng)用。
背景技術(shù):
冬凌草甲素是唇形科(Labtea)香茶菜屬(Rabdosia)植物冬凌草的主要活性成分,是一種四環(huán)二萜類天然產(chǎn)物,具有抗腫瘤、抗菌、β-受體拮抗、抗氧化等廣泛的生理活性(見Liu Z,Ouyang L,Peng H,et al.Cell Proliferat,2012,45,499)。冬凌草甲素具有獨(dú)特的α-亞甲基環(huán)戊酮結(jié)構(gòu),這種結(jié)構(gòu)已經(jīng)被證實(shí)是冬凌草甲素抗腫瘤以及抗菌的活性中心,其對(duì)腫瘤的抑制作用已經(jīng)在體內(nèi)和體外試驗(yàn)中得以證實(shí)并且均具有優(yōu)良的活性;冬凌草甲素具有較廣的抗腫瘤譜,對(duì)多種腫瘤細(xì)胞都有很好的抑制活性。體外活性試驗(yàn)研究表明,冬凌草甲素對(duì)人體食管鱗癌細(xì)胞、s180、艾氏腹水癌、人肝癌BEL-7402、網(wǎng)織細(xì)胞肉瘤實(shí)體型、肺癌SPCA-1、乳腺癌以及白血病等腫瘤具有很好的抑制活性(見李學(xué)湯,張覃沐。藥學(xué)學(xué)報(bào),1985,20,243;王綿英,張覃沐。中國(guó)藥理學(xué)報(bào),1985,6,195)。冬凌草甲素抗腫瘤的分子機(jī)制包括細(xì)胞周期阻滯、細(xì)胞凋亡、細(xì)胞自噬以及其交叉效應(yīng),為冬凌草甲素作為未來(lái)治療腫瘤的候選藥物提供了依據(jù)(見Chunyang Li,Enqin Wang,Yan Cheng,et al.Int J Biochem Cell B,2011,43,701)。
冬凌草甲素屬于二萜類化合物,由于不溶于水,限制了其在臨床上的應(yīng)用。本課題組對(duì)冬凌草甲素C-1和C-14位分別進(jìn)行結(jié)構(gòu)修飾,得到了具有較好抗腫瘤活性的化合物(見ZL200710133915.X;ZL201010509348.5;ZL201110178862.X;ZL201310423035.1;JinyiXu,Jing Yi Yang,et al.Bioorg Med ChemLett,2008,18,4741)。
為尋找制備方便,并具有更強(qiáng)抗腫瘤活性的新藥,本發(fā)明找到了一系列A-環(huán)結(jié)構(gòu)改造的冬凌草甲素類新型化合物,并對(duì)其14-羥基進(jìn)行了衍生化,得到了一系列的A-環(huán)改造冬凌草甲素14位羥基修飾的衍生物。
