Description
技术领域
本发明属于纳米药物载体技术领域,具体涉及一种光热协同化疗的靶向可降解纳米药物载体及其制备方法。
背景技术
国际癌症研究机构2020年12月15日,发布了2020年全球癌症负担报告。摘录全球和我国宫颈癌相关数据,2020年全球新增癌症病例数1929万,其中457万例在中国,占全球新发病例数的23.7%。寻找更加有效的癌症治疗方法已经成为需要攻坚的主要课题。目前,化疗和放疗是现阶段的两种主流治疗方式,但其因低效率和全身毒性等副作用限制了它们的进一步发展。
而对纳米药物载体的研究有望解决低效率和全身毒性的问题,它具有可设计的物理、化学和生物学性能,在一定程度上改善药物在体内组织器官中的分布,有效提高药物利用度,从而提高化疗药物生物安全性。
纳米肿瘤治疗通过化学方法合成结构稳定的纳米材料作为药物载体,纳米级别的载体通过EPR效应能够有效的富集在肿瘤血管附近,并且使得药物特异性释放在肿瘤所处的微环境中,从而使得药物对人体的副作用降低,也可实现一定的对肿瘤细胞抑制的目的。但是,硅基纳米载体药物进入体内后发挥作用以及未发挥作用的纳米粒子,会蓄积在人体的组织器官中,虽然药物不得已释放,但其长期续集会引发炎症等各种生理反应。使得生物安全性得不到解决。因此,对硅基载体进行改进,使其能够解决降解问题是很重要的,而载体的表面修饰是体内循环和提升治疗效率的关键。使其自身在人体内有效作用的之后,能够在体内自身的微环境中得到有效的降解和清除,从而可降解的纳米药物载体得到越来越多的关注,成为近年来研究的热点。
大量研究表明,肿瘤细胞的外表面pH显弱酸性,可以利用这种微环境的特性接入靶向物质,比如带有-NH-的生物素、叶酸等物质。此类物质对pH的特殊响应性,其对肿瘤能够进行特异性的识别,从而达到精准、主动靶向的目的。
介孔二氧化硅具有较高的孔隙率、高比表面积、热稳定性,载药量大、结构稳定、生物相容性好、无毒副作用的特点,但其在体内循环时间较短,且容易蓄积于器官,单一介孔二氧化硅负载后进入人体,不能对病症有效治疗。因此需要从其降解、循环、靶向等方面综合考虑进行纳米载体的设计。
有鉴于此,本发明提出一种新的光热协同化疗的靶向可降解纳米药物载体及其制备方法,满足可降解、靶向、化疗和光热治疗协同的要求,提升效率,减少副作用,这对肿瘤治疗具有重要意义。

实施例1.
具体操作步骤如下:
(1)制备聚多巴胺掺杂的介孔二氧化硅(PDA/MSN):
将25wt%的CTAC(纯度99%)8mL、12mL超纯水、48μL三乙醇胺混合,在60℃搅拌1h,搅拌均匀后,加入50-150mg盐酸多巴胺(纯度98%)并继续搅拌20min。再用恒压漏斗滴加20v/v%的TEOS/环己烷溶液(TEOS纯度GC),在60℃反应12h后,离心洗涤;然后用6g/L的硝酸铵/乙醇溶液在60℃下搅拌12h,洗去CTAC,离心洗涤。最后在不高于40℃的温度下真空干燥,得到灰黑色聚多巴胺掺杂的介孔二氧化硅。

无水乙醇用醋酸调节pH到4后,将150mg聚多巴胺掺杂的介孔二氧化硅分散于40mL乙醇醋酸溶液中,再加入1g的APTES,在60℃下搅拌24h,离心洗涤,得到氨基化修饰聚多巴胺掺杂的介孔二氧化硅(PDA/MSN-NH2)。
(3)制备负载抗癌药物DOX的聚多巴胺掺杂的介孔二氧化硅(DOX@PDA/MSN):
将氨基化的聚多巴胺掺杂的介孔二氧化硅纳米粒子和抗癌药物DOX加入到水中(氨基化的聚多巴胺掺杂的介孔二氧化硅纳米粒子、抗癌药物DOX和水的质量比为1:1.5:1.5),搅拌24h,通过静电作用和Π-Π共轭负载上抗癌药物,得负载抗癌药物DOX的聚多巴胺掺杂的介孔二氧化硅(DOX@PDA/MSN)。
通过对上清液吸光度的测定,进一步定量负载的DOX在纳米颗粒上的吸附量。
(4)CMCS修饰的聚多巴胺掺杂的介孔二氧化硅(PDA/MSN-CMCS):
制备活化的羧甲基壳聚糖(简称CMCS):将10mgCMCS分散于5mL水中,加入25mgEDC和25mgNHS,在N2保护的条件下,室温活化4h后,加入10mg的DOX@PDA/MSN-NH2,超声处理5min,继续搅拌12h,洗涤后,按照1mg/mL的浓度保存在4℃的环境中。
(5)制备叶酸活性酯(FA-NHS):
叶酸活化处理:3g叶酸溶解于30mLDMSO中,加入EDC12g、NHS12g。活化16h后,用15v/v%的丙酮/乙醚将DMSO洗去,剩下粘稠的黄色流体。将黄色流体在20℃下真空干燥,得叶酸活性酯(FA-NHS),保存于冰箱。

为了提高产品的保质期,4℃保存。
对实施例1制备过程中的PDA/MSN、PDA/MSN-NH2、PDA/MSN-CMCS、PDA/MSN-CMCS-FA进行表面电位变化测试,结果如图1所示。结合图1,通过Zeta电位的表征进一步展现了纳米粒子的制备过程。
实施例2.
对实施例1中制备的光热协同化疗的靶向可降解的纳米药物载体进行载药性能测试。
对制备的DOX@PDA/MSN-CMCS-FA纳米粒子进行形貌分析,结果如图2所示,制备了具有高比表面积的聚多巴胺掺杂的介孔二氧化硅,羧甲基壳聚糖的包裹使得表面呈现出聚合物膜,载药量最高可以达到约10%,具有较高的载药量。本发明制备的纳米药物载体的药物负载效果好,为以后的药物或其他大分子、蛋白质等负载提供了可能性。
实施例3:光热性能
将实施例1制备的DOX@PDA/MSN-CMCS-FA纳米粒子,即所述的光热协同化疗的靶向可降解纳米药物载体,在808纳米红外光下进行光热性能的测定。
结果如图3的DOX@PDA/MSN-CMCS-FA的光热效果曲线所示,在808纳米红外光下,随着照射时间的延长,纳米粒子浓度越高,溶液升温越迅速,说明以该方法得到的纳米粒子具有较强的光热转换能力,且红外光照射,减少了对生物体的伤害。
在近红外光照下(808纳米),随着时间增长,浓度越高,升温效果越明显,具有良好的光热性能,可以有效抑制肿瘤生长。
实施例4:测定DOX@PDA/MSN-CMCS-FA纳米粒子的稳定性。
(1)对实施例1制备的叶酸修饰的羧甲基壳聚糖包裹聚多巴胺掺杂的介孔二氧化硅纳米粒子,即所述的光热协同化疗的靶向长循环纳米药物载体(DOX@PDA/MSN-CMCS-FA)。在10%FBS溶液下将纳米粒子充分分散,在制备完成及制备完成后的24小时两个时间点测定纳米粒子的粒径分布。
结果如图4的DOX@PDA/MSN-CMCS的DOX@PDA/MSN-CMCS-FA的纳米粒子稳定性及粒径分布图所示,粒径分布并没有明显变换,且粒径曲线呈正态分布,在200纳米以内,符合高效利用纳米粒子的粒径大小,且纳米粒子可以在体液状态下实现稳定分布存在。
(2)对DOX@PDA/MSN-CMCS-FA在不同pH的PBS溶液中进行释药的实验测试,结果如图5所示。图5为DOX@PDA/MSN-CMCS-FA在pH=5、6.5、7.4的PBS溶液中随时间变化的释药情况。由图5可知,本发明制备的DOX@PDA/MSN-CMCS-FA在不同pH下都可以酸性响应的释药效果。
图6为DOX@PDA/MSN-CMCS-FA在pH=5的PBS溶液中14d后降解图片,尺寸500nm(右)。由图6可知,在酸性条件下,本发明制备的DOX@PDA/MSN-CMCS-FA可以降解。
实施例5:测定该核壳结构纳米粒子细胞毒性
采用不同浓度的实施例1制备的DOX@PDA/MSN-CMCS、DOX@PDA/MSN-CMCS-FA分别与Hela细胞共孵育时,检测细胞毒性,并设置两种不同条件:无近红外光照射和有近红外光照射。结果如图7所示,左图为无近红外光照射,右图为有近红外光照射。
由图7可知,载药后的纳米粒子随DOX@PDA/MSN-CMCS、DOX@PDA/MSN-CMCS-FA浓度的增加具有较好的杀死肿瘤细胞的效果。因DOX@PDA/MSN-CMCS-FA具有靶向效果,细胞存活率(约11%)低于DOX@PDA/MSN-CMCS(约20%),具有更强的细胞毒性,有效提高药物载体的生物利用率。在近红外光的照射下,产生的光热效果对细胞有更强的抑制作用,DOX@PDA/MSN-CMCS-FA+NIR组在100μg/mL浓度下,细胞的存活率更低(约8.5%)。
由本发明的实施例可知,本发明利用生物质材料CMCS、聚多巴胺制备可降解的靶向纳米载体。通过调控所加盐酸多巴胺及表面活性剂十六烷基三甲基氯化铵的比例,制备掺杂的介孔硅,实现纳米粒子的高载药性能。通过引入叶酸,利用肿瘤附近酸性微环境实现纳米粒子的精准靶向。通过以上物质的结合及包覆,锚定,形成宏观尺度下的纳米粒子,使得载药纳米载体具有靶向可降解的特性,同时可以实现药物载体的个性化,降低患者对纳米药物载体的非特异性毒性。
以上所述,仅是本发明实施例的较佳实施例而已,并非对本发明实施例作任何形式上的限制,依据本发明实施例的技术实质对以上实施例所作的任何简单修改、等同变化与修饰,均仍属于本发明实施例技术方案的范围内。
