本發(fā)明涉及醫(yī)藥化學(xué)領(lǐng)域,具體涉及一種具有抗腫瘤活性的高烏甲素氮雜肉桂酸雜合體及其合成方法。
背景技術(shù):
腫瘤已嚴(yán)重威脅到人類的健康,尋找有效安全、毒副作用小的抗腫瘤藥物一直是腫瘤藥物研發(fā)工作者孜孜以求的目標(biāo)。隨著藥物化學(xué)的發(fā)展,尋找高效低毒的天然抗腫瘤化合物或進(jìn)行結(jié)構(gòu)改造合成其衍生物成為當(dāng)前抗腫瘤藥物研究中的一個(gè)重要趨勢(shì)。
高烏甲素[(1α,14α,16β)-20-乙基-1,14,16-三甲氧烏頭烷-4,8,9-三醇4-[2-(乙酰氨基)]苯甲酸酯]是從毛茛科植物高烏頭(Aconitumsinomotanum Nakai)的根中提取的一種生物堿(中國(guó)科學(xué)院植物研究所,中國(guó)高等植物圖鑒(第一冊(cè))[M].北京:科學(xué)出版社,1992,688)。其結(jié)構(gòu)見(jiàn)下式。藥理實(shí)驗(yàn)證明具有較強(qiáng)的中樞鎮(zhèn)痛作用及解熱、消腫和局部麻醉等作用。毒性實(shí)驗(yàn)表明,本品對(duì)各種組織均無(wú)損害,無(wú)致畸作用。
肉桂酸是一種天然的芳香脂肪酸,廣泛存在于蜂膠、咖啡、水果和酒中。肉桂酸有廣泛的藥理性質(zhì),如抗癌、抗氧化、和抗菌。最近的研究表明,肉桂酸具有潛在抗腫瘤活性,如黑色素瘤、惡性膠質(zhì)瘤、胃細(xì)胞腺癌、前列腺癌和肺癌細(xì)胞,它能誘導(dǎo)細(xì)胞凋亡和細(xì)胞骨架的破壞。此外,肉桂酸具有α,β-不飽和酮羰基,在新藥的設(shè)計(jì)中發(fā)揮重要作用,特別是抗腫瘤藥物,抗病毒藥物等。

因此,發(fā)明者決定在現(xiàn)有研究基礎(chǔ)上,以高烏甲素、氮雜肉桂酸及其衍生物為原料,設(shè)計(jì)合成一種結(jié)構(gòu)新穎的高烏甲素氮雜肉桂酸酯類化合物,并在細(xì)胞水平上進(jìn)行抗腫瘤活性研究。

本發(fā)明化合物的抗腫瘤活性測(cè)試
對(duì)本發(fā)明的化合物進(jìn)行了腫瘤細(xì)胞增殖抑制試驗(yàn),試驗(yàn)方法采用常規(guī)的MTT法。
細(xì)胞株選用:人前列腺癌(PC-3),人胃腺癌細(xì)胞(SGC-7901),人肺癌細(xì)胞(A-549)。培養(yǎng)液為DMEM+15%NBS+雙抗。
樣品液的配制:用DMSO(Merck)溶解后,加入PBS(-)配成的100μmol/L的溶液或者均勻的混懸液,然后用DMSO的PBS(-)稀釋,最終濃度分別為0.1,1,10,20,40,60,80,100μmol/L。
將抗腫瘤藥物5-氟尿嘧啶(5-FU)以同樣的條件配成對(duì)照品溶液。
細(xì)胞培養(yǎng):貼壁生長(zhǎng)腫瘤細(xì)胞細(xì)胞培養(yǎng)于含10%滅活新生牛血清和青霉素、鏈霉素(各100萬(wàn)U/L)的1640培養(yǎng)液中,置于37℃,5%CO2,飽和濕度的二氧化碳培養(yǎng)箱中培養(yǎng)。細(xì)胞貼壁生長(zhǎng),每2~3天傳代1次,傳代時(shí)首先倒出培養(yǎng)液,PBS洗2次,胰酶消化后,加入新鮮的培養(yǎng)液吹打均勻,調(diào)整細(xì)胞至適當(dāng)濃度移入新的培養(yǎng)瓶中,添加培養(yǎng)液至適量。取對(duì)數(shù)生長(zhǎng)期細(xì)胞用于實(shí)驗(yàn)。
MTT法檢測(cè)細(xì)胞活性及IC50的測(cè)定:
實(shí)驗(yàn)原理:活細(xì)胞線粒體中脫氫酶能將黃色的MTT還原成不溶于水的藍(lán)紫色產(chǎn)物甲臜(MTT formazan),并沉積在細(xì)胞中,生成的量與活細(xì)胞數(shù)目成正比,而死細(xì)胞沒(méi)有這種功能。DMSO能溶解藍(lán)紫色結(jié)晶物,顏色深淺與所含的量成正比,因此用酶標(biāo)儀測(cè)定的光吸收值可反映細(xì)胞存活率。
實(shí)驗(yàn)方法:取對(duì)數(shù)生長(zhǎng)期細(xì)胞,消化、計(jì)數(shù),以3×105/mL的密度接種于96孔培養(yǎng)板中,每孔100μl。培養(yǎng)24小時(shí)后,將待測(cè)化合物以0.1,1,10,20,40,60,80,100μmol/L濃度處理細(xì)胞。實(shí)驗(yàn)組每個(gè)濃度設(shè)5個(gè)復(fù)孔,以含0.4%DMSO的培養(yǎng)液作對(duì)照。藥物作用48小時(shí)后,去上清,每孔加入100μl MTT(2-(4,5-二甲基-2-噻唑基)-3,5-二苯基-2H-四唑氫溴酸鹽)(1mg/mL),繼續(xù)培養(yǎng)4小時(shí),棄上清,每孔加入100μl DMSO,振蕩混勻,用酶標(biāo)儀在570nm處測(cè)定吸光度值,采用IC50計(jì)算軟件求出半數(shù)抑制濃度(IC50)。
試驗(yàn)結(jié)果詳見(jiàn)表1,其中,樣品是指相應(yīng)實(shí)施例中制備的巖白菜素氮雜肉桂酸酯類化合物,樣品編號(hào)對(duì)應(yīng)制備實(shí)施例中所得到的化合物的具體編號(hào)。
表1化合物對(duì)不同腫瘤細(xì)胞的半數(shù)抑制濃度IC50(單位:μmol/L)
表1結(jié)果顯示,化合物1-19在所測(cè)試的3種細(xì)胞株中均表現(xiàn)出了不同程度的抗腫瘤活性,其中化合物11、12和5的活性較好,對(duì)細(xì)胞呈現(xiàn)較強(qiáng)的抑制效果,在特定細(xì)胞株中抗腫瘤活性優(yōu)于或等同于5-氟尿嘧啶,對(duì)不同腫瘤細(xì)胞株具有明顯選擇性。綜上,本發(fā)明的高烏甲素氮雜肉桂酰胺類化合物可作為抗腫瘤候選藥物進(jìn)一步進(jìn)行臨床前研究,也可以做為抗腫瘤先導(dǎo)化合物進(jìn)一步研究。
