專(zhuān)利名稱:N-(n-苯甲?;奖滨;?-苯丙氨酸二肽衍生物及其制備方法和用途的制作方法
技術(shù)領(lǐng)域:
本發(fā)明屬藥物化學(xué)技術(shù)領(lǐng)域,涉及N-(N-苯甲?;?苯丙氨酰基)-苯丙氨酸二肽衍生物及其制備方法以及其在制備治療病毒性感染特別是乙肝病毒(HBV)感染藥物中的應(yīng)用。
背景技術(shù):
乙型肝炎病毒(Hepatitis B Virus,HBV)感染是影響人類(lèi)健康的全球性主要疾病之一,全球目前有4億多慢性乙型肝炎病毒感染者,其中約75%分布在亞太地區(qū)。慢性乙型肝炎的預(yù)后不良,可發(fā)展為肝硬化和原發(fā)性肝癌,全球每年約有100萬(wàn)人死于乙型肝炎病毒感染的相關(guān)疾病,占疾病死因的第九位。
共價(jià)閉合環(huán)狀DNA(covalently closed circular.DNA,cccDNA)是HBV DNA在宿主細(xì)胞核內(nèi)的存在形式,是HBV復(fù)制和轉(zhuǎn)錄的模板,現(xiàn)有藥物對(duì)核內(nèi)cccDNA無(wú)抑制作用,使得其長(zhǎng)期存在于細(xì)胞核中難以清除,從而導(dǎo)致HBV DNA可持續(xù)復(fù)制。而長(zhǎng)期用藥過(guò)程中又容易導(dǎo)致HBV病毒突變株的產(chǎn)生,如HBV DNA聚合酶YMDD(酪氨酸-蛋氨酸-天冬氨酸-天冬氨酸)的突變,Pre-S基因的突變等)及病人的免疫耐受等原因,造成目前抗病毒治療僅對(duì)一小部分患者有效,使得到目前為止,人類(lèi)在對(duì)付乙肝病毒感染的過(guò)程中還沒(méi)有找到一種確實(shí)有效的理想方法。從乙肝病毒分子生物學(xué)的知識(shí)出發(fā),著眼于乙肝病毒循環(huán)復(fù)制機(jī)理,采用多學(xué)科合作,篩選不同作用機(jī)理和作用形式的創(chuàng)新藥物控制乙肝病毒的復(fù)制,清除體內(nèi)乙肝病毒,抑制病毒突變株的產(chǎn)生,避免停藥后的“反跳”現(xiàn)象是今后藥物化學(xué)工作者攻克的方向。在這一研究方向上,從已知具有較強(qiáng)的抗乙肝病毒活性的天然植物中分離提取抗乙肝病毒活性成分并進(jìn)行結(jié)構(gòu)修飾,發(fā)現(xiàn)療效較理想的藥物,然后進(jìn)行大量的人工合成,是抗乙肝病毒藥物研究的重要途徑。
