本發(fā)明屬于藥物技術(shù)領(lǐng)域,具體地說,涉及rakicidina衍生物,其藥物組合物,及其在制備抗癌或輔助抗癌藥物中的應(yīng)用。
背景技術(shù):
在超過95%的慢性粒細胞白血病(cml)患者中,費城染色體的易位產(chǎn)生了bcr-abl癌基因。相應(yīng)的,伊馬替尼作為一種選擇性的bcr-abl酪氨酸激酶抑制劑現(xiàn)在被用于cml的一線治療,并在臨床中取得了巨大的成功。但是,依馬替尼的耐藥性已成為臨床應(yīng)用中一個重要的問題。例如,有報道,在新診斷的慢性期cml患者中3-4%是伊馬替尼耐藥的。在加速期中,耐藥比例高達40-50%,而在急變期患者中,耐藥性可超過80%。為了克服伊馬替尼獲得耐藥性,近期越來越多的酪氨酸激酶抑制劑被研發(fā)出來,并用于cml的二線治療,例如nilotinib,dasatinib以及bosutinib。但是這些新藥對于攜帶t315i突變的患者無效。因此,人們依然在尋找克服伊馬替尼耐藥性的治療方法,但目前結(jié)果并不盡如人意。為了迎接這種挑戰(zhàn),許多其他作用機制的新化合物亟待被研發(fā)。
在包括cml的許多癌癥中,具有一類表現(xiàn)出干細胞性質(zhì)的細胞。這些被稱為癌癥干細胞的細胞癌癥產(chǎn)生耐藥,復(fù)發(fā)及轉(zhuǎn)移的主要原因。對于cml來說,bcr-abl酪氨酸激酶抑制劑那一治療cml干細胞,而這些細胞將導(dǎo)致臨床治療中出現(xiàn)伊馬替尼耐藥性。而且,酪氨酸激酶抑制劑的使用將促使骨髓中的cml干細胞的歸巢和生存。有報道稱,一些小分子具有選擇性抑制cml干細胞的活性,但是研發(fā)特異性抗癌癥干細胞治療藥物的努力還沒有產(chǎn)生預(yù)期的效果。
據(jù)報道,天然產(chǎn)物rakicidina可以顯著性的誘導(dǎo)實體瘤中的低氧選擇細胞毒性,并且可以誘導(dǎo)酪氨酸激酶抑制劑耐藥性的cml干細胞樣細胞死亡。rakicidina首先從micromonosporasp.提取物中分離獲得,隨后包括rakicidina,b,c及d等一系列脂肽類化合物被鑒定出來。總體來說,rakicidin類化合物具有一種獨特的4-氨基-2,4-戊二烯酮結(jié)構(gòu),并且,該結(jié)構(gòu)在在如microtermolidea,vinylamycin及be-43547a1等天然產(chǎn)物中也被發(fā)現(xiàn)。
rakicidin類化合物由于其機構(gòu)和生物活性特點,在合成和藥物研究方面都引起了人們的興趣。最近,我們預(yù)測了rakicidina的五個未知的手性中心的構(gòu)型為2s,3s,14s,15s和16r。這些預(yù)測隨后通過對rakicidina進行合成及表征并通過對rakicidina天然產(chǎn)物的降解實驗獲得證實。在rakicidina的合成中人們發(fā)現(xiàn),rakicidina具有合成難度高,化合物不穩(wěn)定等缺點。本發(fā)明在已有發(fā)現(xiàn)的基礎(chǔ)上,合成了rakicidina的衍生物,該衍生物具有治療癌癥的作用。

實施例13:rakicidina衍生物的藥理作用
將各種癌細胞配成2×105/ml細胞懸液,加入24孔板圓底細胞培養(yǎng)板內(nèi),分別加入rakicidina衍生物,每一測試濃度5孔,置37℃、5%co2飽和濕度條件下培養(yǎng)72小時,用mtt法在酶聯(lián)檢測儀570nm波長測得吸光度(a)值,計算出本發(fā)明化合物對測試癌細胞的抑制作用。
表1rakicidina衍生物對各種癌細胞的抑制活性(ic50,μm)
其中k562、k562/g+分別表示慢性粒細胞白血病和耐伊馬替尼慢性粒細胞白血病細胞株。
活性測試結(jié)果表明,篩選的化合物對受試細胞顯示出抑制活性。因此測試化合物具有用于治療癌癥用途。
