Description
技术领域
本发明属于医药技术领域,涉及多西他赛亚油酸酯及其脂肪乳剂和在制备抗肿瘤药物方面的应用。
背景技术
多西他赛,属于紫杉烷类化合物,临床上作为抗肿瘤化疗药使用,主要治疗乳腺癌、卵巢癌和非小细胞肺癌等。在肿瘤细胞生长过程中,多西他赛与细胞中微管蛋白能强力地结合,抑制其有丝分裂,进而抑制肿瘤细胞的增殖,最终诱导肿瘤死亡。
多西他赛的分子式为C43H53NO14
结构式如下:
目前,市场上主要应用的是其注射液形式,该制剂由于稳定性差,市售剂型为以吐温80作为潜溶剂的浓缩液,在静脉滴注前再用乙醇水溶液配置成预注射液,最后用生理盐水或5%葡萄糖溶液稀释后才能使用,极不方便,而且整个过程可能造成药物的二次污染。与辅料有关的各种过敏反应、神经毒性、溶血等副作用也给病人带来严重的灾难,亟需找到新的剂型去改善这一现状。
乳剂是难溶性和不溶性药物的良好载体,而且能够降低毒副作用和稳定药物。国内已有多个关于多西他赛脂肪乳的申请专利:如专利CN100998559A(多烯紫杉醇亚微乳注射剂及其制备方法)、CN101433533A(一种紫杉醇或多烯紫杉醇的静脉注射乳剂)、CN102274181A(一种多西他赛脂质微球注射液及其制备方法)等。但是,这些方法制备的脂肪乳载药量和包封率较低,抗肿瘤效果不显著,远远未达到药物本身的治疗目的。亚油酸是人体必需的多不饱和脂肪酸,有研究表明,肿瘤地快速增殖需要大量摄取亚油酸(CLAreduces breast cancer cell growth and invasion through ERαand PI3K/Aktpathways.Chem-biol.Interact.183,187-193.)。多西他赛,难溶于水,连接亚油酸后脂溶性增加,更易溶于油相。当制备成油包水型脂肪乳剂时,一方面可以补充患者所需营养并且增大载药量,另一方面可以借助亚油酸的“营养靶向”作用,增强抗肿瘤效果。
发明内容
基于上述背景技术,我们合成了多西他赛亚油酸酯,并将其制备成直接用于静脉注射使用的多西他赛亚油酸酯脂肪乳剂。多西他赛经亚油酸修饰后,脂溶性明显增加,制备成脂肪乳具有良好的包载效果和储存稳定性。进一步的体内研究表明,制备所得的脂肪乳剂具有延长半衰期,抑瘤效果显著等优势。
本发明所述的多西他赛亚油酸酯的结构如式(I)所示:

表2多西他赛亚油酸酯脂肪乳剂稳定性试验结果
表2稳定性试验结果表明,当中链甘油三酯:长链甘油三酯=1~5:1时,蛋黄卵磷脂:泊洛沙姆188=3.75~15:1时,多西他赛亚油酸酯脂肪乳剂均较稳定;其中,中链甘油三酯:长链甘油三酯=3:1,蛋黄卵磷脂:泊洛沙姆188=7.5:1时最稳定。
包封率试验
依据中国药典(2015年版)第四部微粒制剂指导原则(通则9014),将各处方的脂肪乳剂用低温高速离心机在13000rpm,2~4℃的条件下离心1h,上层即为脂肪乳溶液。分别取一定体积的离心前后的脂肪乳,经乙腈破坏后进液相测定含量,并计算包封率,结果见下表3。
包封率(%)=离心后脂肪乳中药物含量/离心前脂肪乳中药物含量×100%
表3多西他赛亚油酸酯脂肪乳剂包封率试验结果(n=3)
表3包封试验结果表明,当中链甘油三酯:长链甘油三酯=1~5:1时,蛋黄卵磷脂:泊洛沙姆188=3.75~15:1时,多西他赛亚油酸酯脂肪乳剂均具有较高的包封率;其中,中链甘油三酯:长链甘油三酯=3:1,蛋黄卵磷脂:泊洛沙姆188=7.5:1时包封率最高。
体内药动学试验
取多西他赛注射液(泰索帝),多西他赛脂肪乳(实施例13)和多西他赛亚油酸酯脂肪乳(以优选的实施例8和最优选的实施例5为例),按5mg/kg的剂量Sprague Dawley大鼠尾静脉注射给药。于给药后5min、15min、30min、1h、2h、4h、8h、12h、24h经大鼠眼球后静脉丛取血约0.4ml,置肝素化试管中,13000rpm离心10min,分离血浆(-80℃冰箱保存),并按如下方法处理样品:向50μl血浆样品中加入50μl内标溶液(地西泮,5ng/ml),涡旋混合1min,加入150μl乙腈,涡旋3min,13000rpm离心15min,取上清液采用液相色谱-串联质谱(LC-MS/MS)法测定含量。
标准曲线的制备
取空白血浆50μl,加入多西他赛(或多西他赛亚油酸酯)标准系列溶液50μl,内标(5ng/ml地西泮)50μl,制备成相当于血浆浓度为10,20,50,200,500,2000,5000ng/ml的样品,血浆样品按《中国药典》2015年版二部中的“血浆样品处理法”操作,建立标准曲线;以待测物浓度为横坐标,待测物与内标物的峰面积比值为纵坐标,用加权最小二乘法进行回归运算,求得的直线方程为标准曲线。
表4大鼠体内药动学试验结果(n=5)
*,p<0.05,**,p<0.01,***,p<0.001
表4药动结果表明,多西他赛亚油酸酯脂肪乳生物利用度远高于多西他赛注射液和多西他赛脂肪乳,并且大大延长了半衰期。
药效学试验
取18~22g雌性BALB/c小鼠,于小鼠右侧背部皮下注射约5×106个4T1细胞。待肿瘤长至150mm3时,挑选30只,平均分为四组,每组各5只。四组分别给予等量的生理盐水、空白乳、多西他赛注射液、多西他赛脂肪乳和多西他赛亚油酸酯脂肪乳,以多西他赛计算,给药剂量为10mg/kg。每隔两天给药一次,连续给药4次,第12天处死小鼠,剖出肿瘤,计算抑瘤率,结果见下表5。
抑瘤率(%)=(生理盐水组平均瘤重-试验组平均瘤重)/生理盐水组平均瘤重×100%
表5小鼠体内药效学试验结果(n=5)
表5药效结果表明,抑瘤率大小顺序为:多西他赛亚油酸酯脂肪乳>多西他赛脂肪乳组>多西他赛注射液>多西他赛油酸酯脂肪乳。
