    摘要:
    一种新的多学科合成方法,包括聚合物-载体合成,微波辅助合成和多组分缩合,促进了三氮芴芴库的合成,并具有一系列优点,例如快速处理,简单纯化和一次即可完成结构多样性。微波辅助多步合成规程用于使用活化的芳基氟化物在可溶性聚合物载体上构建苯并咪唑环。所述PEG锚定氟化芳基是通过具有选择性的伯胺缩合本位-氟取代反应,然后还原硝基。随后用溴化氰进行环化是提供固定化苯并咪唑的关键步骤。最后,在微波辐射下,所得聚合物结合的苯并咪唑与各种醛和1,3-二酮的多组分缩合反应提供了高纯度,高收率的三氮杂芴的快速通道。微波辐射极大地加快了所有反应的速度,而聚合物载体通过简单的沉淀技术促进了纯化。这种策略大大提高了整体多步合成的效率。

  • pH-responsive polymeric carrier encapsulated magnetic nanoparticles for cancer targeted imaging and delivery

    Multifunctional drug delivery systems with favorable compatibility, high selectivity and efficiency are appropriate candidates for future medical applications. For this purpose, a multifunctional nanocomposite that enables selective magnetic resonance imaging and anticancer therapy by encapsulating hydrophobic superparamagnetic nanoparticles and chemotherapeutic agent doxorubicin with a novel biodegradable pH-activated polymeric carrier was synthesized. The as-synthesized amphiphilic polymer has excellent biocompatibility and pH-responsivity. The obtained nanocomposites selectively release the encapsulated drug and magnetic nanoparticles in mildly acidic endosomal/lysosomal compartments due to the degradation of the pH-responsive bonds, resulting in a change of imaging signal and cancer therapy. Furthermore, when compared with the nanocomposites without a targeting moiety, as studied from over-expression of the folic acid receptor tumor cell culturing, the conjugates with folic acid showed a significantly more potent targeting capability.

    A water-soluble, pH-responsive copolymer was synthesized successfully and used as a polymeric carrier to deliver hydrophobic paramagnetic nanoparticles into cells. In an acidic environment, the nanoparticles aggregate as the copolymer degrades, resulting in the enhancement of an in vitro MRI signal.

  • A facile preparation of targetable pH-sensitive polymeric nanocarriers with encapsulated magnetic nanoparticles for controlled drug release

    Novel multifunctional nanocomposites were successfully prepared for the controlled release of anti-cancer drug and magnetic resonance imaging (MRI) via a simple self-assembly process. In this strategy, superparamagnetic iron oxide nanoparticles (SPIONPs) were “fixed” between the hydrophobic segment of the pH-sensitive amphiphilic polymer (HAMAFA-b-DBAM) and the surface of hollow mesoporous silica nanoparticles (HMS) which were modified by the long-chain hydrocarbon octadecyltrimethoxysilane (C18). Since the amphiphilic polymer was conjugated with a folic acid (FA) group, the nanocomposites could target the folic acid receptor (FR) of over-expressed tumor cells efficiently. Moreover, high drug loading content was obtained simultaneously due to the hollow core of HMS. The loaded drug could release from the HMS core triggered by the mildly acidic pH environment in the cancer cells due to the hydrolysis of the pH-sensitive polymer shell. The targeting process of the nanocomposites could be easily tracked by MRI due to the magnetism of the SPIONPs. Therefore, a nanocarrier with high drug-loading capacity and controlled drug release property for tumor diagnosis and therapy was obtained via the self-assembly of HMS core, magnetic Fe3O4 nanoparticles and targetable pH-sensitive polymer shell.
    通过简单的自组装过程,成功制备了新型多功能纳米复合材料,用于抗癌药物的控制释放和磁共振成像(MRI)。在这一策略中,超顺磁性氧化铁纳米粒子(SPIONPs)被 "固定 "在 pH 敏感性亲水聚合物(HAMAFA-b-DBAM)的疏水段和中空介孔二氧化硅纳米粒子(HMS)表面之间,而中空介孔二氧化硅纳米粒子则由长链碳氢化合物十八烷基三甲氧基硅烷(C18)修饰。由于两亲性聚合物与叶酸(FA)基团共轭,纳米复合材料能有效靶向过度表达的肿瘤细胞的叶酸受体(FR)。此外,由于 HMS 的中空内核,还能同时获得较高的药物负载量。当癌细胞内的 pH 值呈弱酸性时,对 pH 值敏感的聚合物外壳会发生水解,从而使负载的药物从 HMS 内核中释放出来。由于 SPIONPs 的磁性,纳米复合材料的靶向过程很容易被磁共振成像跟踪。因此,通过 HMS 内核、磁性 Fe3O4 纳米粒子和可靶向的 pH 敏感聚合物外壳的自组装,获得了一种具有高载药量和可控药物释放特性的纳米载体,可用于肿瘤诊断和治疗。
