專利名稱::新的甘草次酸衍生物、其制備方法及其醫(yī)藥用途的制作方法
技術(shù)領(lǐng)域
:本發(fā)明涉及藥物領(lǐng)域,具體涉及一類一氧化氮供體型甘草次酸衍生物及其藥學(xué)上可接受的鹽,它們的制備方法,含有這些衍生物的藥用組合物以及它們的醫(yī)藥用途,特別是在制備治療腫瘤疾病的藥物的應(yīng)用。
背景技術(shù)
:甘草屬于豆科植物,主要分布于我國(guó)西部及俄羅斯等國(guó)家與地區(qū),它是我國(guó)常用的中草藥品種之一。甘草酸及其苷元甘草次酸(glycyrrheticacid,簡(jiǎn)稱GA)是甘草的主要藥理活性物質(zhì)。甘草次酸又稱甘草亭酸,它是由甘草酸水解得到的五環(huán)三萜類化合物,其中以1813-甘草次酸為主。研究表明,甘草次酸具有抗炎、抗?jié)?、抗病毒、降血脂、保護(hù)心肌和治療缺血性心肌炎、清除體內(nèi)自由基、促進(jìn)胰島素吸收、抗癌及防癌等多種藥理活性(金敏,吳紅金.醫(yī)學(xué)綜述,2009,15(11):1712-1715)。<formula>formulaseeoriginaldocumentpage5</formula>卄草次酸在抗腫瘤方面,研究表明,甘草次酸可抑制白血病、肝癌、結(jié)腸癌、胃癌、乳腺癌、宮頸癌等多種腫瘤細(xì)胞的增殖。其抗癌作用機(jī)制可能涉及抑制p-糖蛋白和多藥耐藥蛋白l,使細(xì)胞分裂停滯在Gl期,阻止促分裂原活化蛋白激酶的磷酸化,誘導(dǎo)線粒體細(xì)胞膜滲透性變化,導(dǎo)致細(xì)胞色素c的釋放,激活細(xì)胞凋亡蛋白酶等(NabekuraT,YamakiT,UenoK,etal.CancerChemotherPharmacol,2008,62(5):867-873)。然而,甘草次酸抗腫瘤活性相對(duì)較弱(黃煒,黃濟(jì)群,張東方,等.中西醫(yī)結(jié)合肝病雜志,2003,13(3):148-150;黃煒,黃濟(jì)群,張東方,等.中國(guó)肺癌雜志,2003,6(4):254-257)。為了進(jìn)一步提高甘草次酸的抗腫瘤活性,人們對(duì)其進(jìn)行了結(jié)構(gòu)修飾與改造,獲得了一些活性較高的甘草次酸衍生物(W02008000070)?!趸?簡(jiǎn)稱NO)是哺乳動(dòng)物體內(nèi)重要的信使物質(zhì)及效應(yīng)分子。近年來(lái),NO在腫瘤的發(fā)生、發(fā)展和死亡中的作用已成為腫瘤研究與治療的熱點(diǎn)之一(MocellinS.CurrCancerDrugTargets,2009,9(2):214-236;CoulterJA,McCarthyHO,XiangJ,etal.NitricOxide,2008,19(2):192-198)。大量研究表明,體內(nèi)持續(xù)低濃度的NO可以促進(jìn)細(xì)胞的生長(zhǎng),抑制細(xì)胞凋亡;而高濃度的NO則產(chǎn)生細(xì)胞毒性,誘導(dǎo)腫瘤細(xì)胞凋亡,阻止腫瘤細(xì)胞的擴(kuò)散和轉(zhuǎn)移(HuertaS,ChilkaS,BonavidaB.IntJOncol,2008,33(5):909-927)。NO供體是指一類在體內(nèi)經(jīng)酶或非酶作用釋放一定量NO的化合物。呋咱氮氧化物(Furoxan)是一類重要的NO供體,由其產(chǎn)生的高濃度NO具有抗腫瘤活性(ChenL,ZhangY,KongX,etal.JMedChem,2008,51(15):4834-4838)。本發(fā)明公開(kāi)了一類具有藥用價(jià)值的新的呋咱氮氧化物類NO供體型甘草次酸衍生物及其藥學(xué)上可接受的鹽,目前尚未見(jiàn)對(duì)此類化合物的任何報(bào)道。本發(fā)明首次公開(kāi)了一類具有抗腫瘤活性的呋咱氮氧化物類NO供體型甘草次酸衍
