Description
技术领域
本发明属于功能性纳米胶束及其制备和应用领域,特别涉及一种亚磷酸酯钠盐修饰的两亲性含磷树冠大分子纳米胶束及其制备和应用。
背景技术
化疗是目前临床上用于急性肺损伤治疗的手段之一。化疗药物能有效抑制肺泡巨噬细胞促炎性细胞因子的分泌,调节促炎性细胞因子和抗炎性细胞因子的分泌平衡,并显著消除活性氧(ROS)从而降低肺部组织的损伤。同时,传统化疗药物的缺陷也是很明显的,一方面其毒副作用将对健康的器官和组织造成损伤;另一方面由于药物利用度低使得给药剂量过高,加剧了药物的毒副作用。因此构建安全且高效的药物载体,增强肺损伤的抗炎与抗氧化药物治疗效果备受研究人员的关注。在药物载体系统中,化疗药物的负载方式主要包括物理包裹和化学键合。其中,化学键合可以实现纳米载体与药物复合材料稳定存在,但也使得药物的释放受限。物理包裹主要包括吸附作用、静电作用和疏水作用,其药物上载量大、易于实现肺损伤病灶部位药物响应性释放等特点,使其更合适作为纳米载药平台。
纳米药物载体中,树状大分子具有独特的高度支化三维立体结构,可作为一种新型的高分子载体广泛地应用于纳米载药平台。聚酰胺-胺树状大分子(PAMAM)由于其疏水的内部空腔结构,可以通过物理包裹或者静电吸附来负载药物(例如阿霉素),还可以在树状大分子表面修饰靶向试剂(叶酸、RGD多肽等)和水溶性的基团(例如聚乙二醇),从而使载体通过主动靶向病灶部位达到更好的治疗效果(Wang et al,Polymer Chemistry,2011,2(8),1754-1760)。与此同时,表面修饰叶酸的树状大分子负载钆配合物,然后内部包裹DOX可用于癌细胞的靶向MR成像和化疗,合成的材料的药物包封率达到了79.8%,药物上载率为5.7%,同时对pH敏感,可以在弱酸的环境下实现药物的快速释放(Zhu et al,RSCAdvances,2015,5(38),30286-30296)。树状大分子有限的内部空腔限制了药物的负载,而两亲性PAMAM树冠大分子,作为一类具有疏水侧链和亲水端基部分的树冠大分子,能够形成稳定的纳米胶束,可用于负载疏水药物DOX且具有较高的包封率(65%)和上载率(42%)(Wei,T.et al.,PNAS,2015,112(10),2978-2983)。然而,PAMAM树形分子的缺枝结构及分子量不均一的缺陷限制了其在纳米医药方面的临床应用。与之相比,含磷树状大分子由于其分子量分布均一,骨架结构精准和表面易功能化的特点而具备巨大的生物医学应用潜力,但由于含磷树状大分子的刚性分子结构,很难作为药物载体构建纳米载药体系。为了解决这个问题,作为含磷树状大分子家族重要成员的两亲性含磷树冠大分子受到了研究者关注。两亲性含磷树冠大分子是一种具有疏水部分和亲水端基部分的树冠大分子,其在水溶液中能够形成尺寸均一的纳米胶束。研究表明该纳米胶束内部具有疏水空腔可用于负载疏水性药物,其包封率(96.71%)和上载率(42.36%)高于PAMAM型树冠大分子(曹流,陈亮.一种两亲性PN=PS型含磷树冠大分子纳米胶束的制备方法及其药物载体应用,中国,CN202010535188.5[P],2020-10-30)。
根据表面不同的功能化修饰,含磷树状大分子可以分为阳离子型、阴离子型和金属离子型含磷树状大分子。已有研究表明,吡咯烷修饰并质子化的阳离子型含磷树状大分子因其具有良好的酸离解常数,表现出优异的基因负载能力,可以高效负载治疗性基因(TNF-αsiRNA)用于小鼠急性肺损伤基因治疗(Bohr et al,Biomacromolecules,2017,18(8),2379-2388)。含磷树状大分子表面修饰金属螯合配体可用于螯合金属离子(Cu(II)、Au(III)等)形成金属离子型含磷树状大分子,可以通过促进肿瘤细胞凋亡和阻滞肿瘤细胞周期,从而抑制肿瘤细胞增殖(Serge M.et al,Molecular Pharmaceutics,2017,14(11),4087-4097)。亚磷酸酯钠盐修饰的阴离子型含磷树状大分子可以通过Toll-like受体(TLR-2)介导,被单核细胞特异性吞噬并激活单核细胞,降低促炎性细胞因子分泌(Poupot etal.Faseb Journal,2006,20(13)2339-2351)。但由于功能化修饰的含磷树状大分子的刚性分子结构和有限的内部空腔限制了其药物负载的能力,因此难以实现多重治疗方式的联合治疗。
肺泡巨噬细胞在急性肺损伤、急性呼吸窘迫综合征和肺炎等肺部疾病的发生发展过程中起着至关重要的作用,急性肺损伤病灶部位肺泡巨噬细胞倾向于M1型巨噬细胞极化,分泌大量促炎性细胞因子(TNF-α、IL-1β和IL-6)等,加速机体炎症,损伤肺泡上皮细胞和肺毛细血管内皮细胞,导致肺水肿和肺换气功能障碍。与此同时,氧化应激也是急性肺损伤产生和进展的重要因素。肺泡巨噬细胞大量产生活性氧一方面可以引起肺血管内皮细胞和肺上皮细胞的氧化应激反应,进而引起细胞的损伤甚至凋亡;另一方面可以激活肺泡巨噬细胞核转录因子(NF-кB)和激活蛋白调控(AP-1)信号调节通路,促进促炎性细胞因子(TNF-α、IL-1β)的分泌。姜黄素(Cur)是一种从植物姜黄中提取的多酚类活性成分。Cur含有2个苯丙烯酰基骨架,前后两个苯环对称,其上有酚羟基甲氧基,其丙烯基与一个β-双酮/烯醇式结构连接。这类含有两个羟基基团的酚类物质在抗氧化过程中会产生强稳定性醌类物质,表现出优异的氧自由基清除能力。但是,由于Cur自身特性(水溶性及药物特异性差)限制了其在炎症疾病治疗中的应用。
检索国内外相关文献和专利结果表明:CN 111848685 A公开了一种两亲性PN=PS型含磷树冠大分子纳米胶束的制备方法及其药物载体应用,可以用于有效负载疏水性化疗药物,但其载体本身并无治疗效果,因此治疗效果单一。而关于亚磷酸酯钠盐修饰的两亲性含磷树冠大分子纳米胶束的制备及其作为化疗药物载体用于药物传递的研究,尚未见报道。

分别配制材料浓度相同的C11G3-TBP和C11G3-TBP@Cur水溶液(C11G3-TBP和Cur的摩尔比为1:20,C11G3-TBP浓度为41.7μM),通过马尔文激光粒度仪(Malvern,UK,633nm激光)对C11G3-TBP及C11G3-TBP@Cur的水动力学粒径及表面电势进行表征。结果显示,相较于C11G3-TBP(122.2nm),C11G3-TBP@Cur(199.2nm)的水合粒径有所增大(附图11),而Zeta电势有一定程度的降低(附图12)。将41.7μM的C11G3-TBP溶液稀释10倍,制备低于CMC的C11G3-TBP溶液,通过动态光散射仪测量其粒径。结果显示,胶束形成后将溶液稀释至CMC以下,胶束形态不会被破坏,但此时的水合粒径为213.5nm,基本维持不变(附图11)。配制2.5mg/mL的C11G3-TBP和C11G3-TBP@Cur溶液样品超声处理5min并稳定2h,然后用超纯水稀释至0.25mg/mL。将样品溶液滴在原子力显微镜(AFM)专用硅片上,室温静置2h,随后用氮气将液体吹离硅片,将样品置于AFM中进行观察和AFM图片拍摄。通过粒径分布分析,纳米胶束C11G3-TBP(附图13a和13c)和C11G3-TBP@Cur(附图13b和13d)的高度分别为39.1nm和40.2nm,这说明C11G3-TBP纳米胶束的内部疏水空腔负载疏水药物Cur后并没有明显改变纳米胶束的结构。

收集对数生长期MH-S细胞,按照8000个细胞每孔的密度接种在96孔细胞培养板上,置于5%CO2,37℃条件下孵育过夜,添加2μg/mL LPS孵育细胞24h,弃掉培养基后,每孔更换90μL无血清(FBS)培养基,并添加10μL含不同浓度的材料(最终相对Cur浓度为0、1.25、2.5、5、10、20μM;最终相对C11G3-TBP浓度为0、4.45、8.9、17.8、35.6、71.2μM)。之后将细胞培养板继续放置在5%CO2,37℃继续孵育24h。随后弃掉原培养基,加入含100μL含有10%CCK-8的无血清培养基,继续培养3h后,放置在多功能酶标仪中于测试波长450nm下测试吸光值,结果如图14所示。与对照组(材料浓度为0,PBS溶液)相比,C11G3-TBP@Cur、C11G3-TBP和游离的Cur在试验浓度范围内对MH-S细胞没有毒性,浓度为20μM时,细胞存活率均为超过75%。

实施例7
将每孔1×105MH-S细胞种植于12孔板中,培养过夜加入LPS孵育24h建立细胞模型,以不添加LPS作为对照组。弃去培养基,替换成不含FBS的培养基,分别加入100μL的一定浓度的Cur(浓度为0.18μM),C11G3-TBP@Cur(Cur浓度为0.18μM)和C11G3-TBP(浓度为10μM)与细胞共培养4h。弃去培养基,用PBS洗3遍,更换新鲜培养基培养24h。用胰酶消化并收集细胞,利用RT-PCR检测促炎性细胞因子编码基因的表达。具体实验步骤如下:
(1)总RNA抽提:裂解细胞样本,低温离心提取总RNA,加入无RNA酶的水(DEP C)溶解RNA。(2)反转录:取一个PCR管,加入含1μg RNA的溶液。加入1μLgDNAEZ eraser和1μLgDNAEZeraser buffer(10×)去除基因组污染,用DEPC水补足至10μL。于PCR仪上55℃保温5min,迅速置冰上冷却。加入cDNA第一链合成预混液(反转录酶、核糖核酸酶抑制剂、随机引物、脱氧核糖核酸、氯化镁和反转录反应缓冲液)用枪抽吸混匀。于PCR仪上42℃保温60min,结束后80℃保温5min灭活反转录酶。(3)定量PCR:取0.25ml PCR管,配制如下反应体系,每个反转录产物配制3管,2×qPCR Mix,5μM基因引物混合物,反转录产物,DEPC水。(4)PCR扩增:在PCR仪中进行变性、退火和延伸的多次循环以扩增目的基因。结果显示(附图16),相对于LPS处理组,C11G3-TBP和Cur处理组能在一定程度上抑制抗炎性细胞因子(TNF-α、IL-1β和IL-6)编码基因表达。与纯Cur和C11G3-TBP处理组相比,C11G3-TBP@Cur组的TNF-α、IL-1β和IL-6编码基因的表达量抑制更明显。这说明亚磷酸酯钠盐修饰的C11G3-TBP@Cur能够实现增强型抗炎效果。
实施例8
