背景技術(shù)
:近50年來(lái),抗腫瘤藥物的研究與開發(fā)取得了很大進(jìn)展,據(jù)報(bào)道,全球有超過(guò)200萬(wàn)個(gè)樣品曾用動(dòng)物體內(nèi)模型進(jìn)行篩選,使用細(xì)胞培養(yǎng)或其他檢測(cè)方法進(jìn)行篩選的樣品更是難以計(jì)數(shù)。按照來(lái)源抗腫瘤藥物大致可以分為化學(xué)合成藥物、植物來(lái)源藥物、微生物來(lái)源藥物和生物技術(shù)藥物。自然界植物資源豐富,是研制新藥的主要來(lái)源。目前,臨床應(yīng)用的抗腫瘤藥物中,來(lái)源于植物的約占1/3,包括了植物原形成分和它們的衍生物,其中生物堿及其衍生物占據(jù)了重要的部分,如長(zhǎng)春花堿類生物堿長(zhǎng)春堿、長(zhǎng)春新堿、長(zhǎng)春地辛和長(zhǎng)春瑞濱;喜樹生物堿包括喜樹堿、羥基喜樹堿、伊諾替康、拓?fù)涮婵导?-氨基喜樹堿;紫杉醇及其同類物;其他生物堿類還有三尖杉酯堿、秋水仙堿等。長(zhǎng)春堿類與紫杉醇作用于微管系統(tǒng)促進(jìn)微管蛋白解聚或聚合,喜樹堿類作用于拓?fù)洚悩?gòu)酶,而三尖杉酯堿主要是抑制蛋白質(zhì)與DNA的合成。植物成分化學(xué)結(jié)構(gòu)與作用機(jī)制的多樣性表明,從植物來(lái)源的藥物是尋找作用與各種靶點(diǎn)的活性物質(zhì)有巨大潛力,因而,對(duì)于新生物堿的發(fā)現(xiàn)和結(jié)構(gòu)修飾也成為抗腫瘤藥物研究的熱點(diǎn)之一。迄今為止,己經(jīng)從植物、動(dòng)物及微生物中分離及鑒定的6000多個(gè)生物堿中,將近150種天然生物堿的結(jié)構(gòu)中具有喹唑啉或喹唑啉酮結(jié)構(gòu)單元,喹唑啉酮類生物堿具有廣泛的生物活性,如Febrifogine(—種從亞洲植物Dichroafebrifiiga提取分離,具有治療瘧疾作用,)被中醫(yī)用于治療瘧疾;Methaqualone有鎮(zhèn)靜催眠作用;bronchodilating有治療低血壓、驅(qū)蟲、抗過(guò)敏的作用,在印度被用于治療風(fēng)寒咳嗽、支氣管炎、風(fēng)濕病、肺結(jié)核及哮喘等疾??;而mtaecarpine、(-)vasicinone及l(fā)uotonin類有抗腫瘤作用更是引起了藥物化學(xué)家們的廣泛興趣。對(duì)于喹唑啉類生物堿的抗腫瘤研究比較多的是luotoninA,它對(duì)鼠類白血病細(xì)胞P-388的IC5o=1.8mg/mL,對(duì)人DNA拓?fù)洚悩?gòu)酶I的IC5Q5.7-12.6mmol/mL。喹唑啉類生物堿的其他作用還有抗真菌、抗炎以及抗高血壓等,這刺激人們制備更多的喹唑啉酮類衍生物,并對(duì)它們的活性進(jìn)行研究,而這也正是藥物化學(xué)家和藥理學(xué)家研究的領(lǐng)域之一
