To mimic the helical structure and function of biopolymers, shell cross-linked nanoparticle (P4) composed of left-handed helical poly(phenylborate isocyanide) in core and hydrophilic polyisocyanide in shell was prepared. The phenylborate in the core and the disulfide bonds in the cross-linkage render the nanoparticle with excellent dual stimuli-responsiveness to glutathione (GSH) and H2O2. Nevertheless, it has good stability in normal physiological conditions. Because of the helicity and borate pendants of the core, such nanoparticle has high capacity for anticancer drug loading, for example, the loading capacity of doxorubicin (DOX) was up to 68%. Moreover, the DOX-loaded DOX@P4 showed excellent tumor cell penetration potency and fast drug release. More than 78% of murine breast cancer cell (4T1) can be killed within 48 h, supporting this material with great potential in antitumor drug nanocarriers.

具有H2O2/氧化还原双重响应性的壳交联螺旋多聚苯硼酸异氰化物纳米粒子的可控合成及其在抗肿瘤药物递送中的应用
为了模拟生物聚合物的螺旋结构和功能,制备了由左旋螺旋聚(苯硼酸异氰化物)核和亲水性聚异氰化物组成的壳交联纳米颗粒(P4)。核心中的苯硼酸盐和交联中的二硫键使纳米粒子对谷胱甘肽(GSH)和H 2 O 2具有优异的双重刺激响应性. 然而,它在正常生理条件下具有良好的稳定性。由于核心的螺旋性和硼酸盐悬垂性,这种纳米颗粒具有很高的抗癌药物负载能力,例如阿霉素(DOX)的负载能力高达68%。此外,载有 DOX 的 DOX@P4 显示出优异的肿瘤细胞穿透能力和快速的药物释放。超过 78% 的鼠乳腺癌细胞(4T1)可以在 48 小时内被杀死,支持这种材料在抗肿瘤药物纳米载体中的巨大潜力。
