Combined chemo–phototherapy for boosting the efficacy of individual modalities by synergism for antiglioma treatments is in its embryonic stage and far away from effective clinical translation. Herein, moving a step closer, we recommend a facile stratagem to fabricate smart biocompatible and biodegradable multifunctional nanoplatforms comprising inherently fluorescent poly(levodopamine) nanoparticles (FLs) co-loaded with doxorubicin (DOX) and indocyanine green (ICG). The designed near-infrared (NIR) phototheranostic agents upon NIR laser irradiation helped precipitate combined chemo–phototherapy [both photothermal therapy (PTT) and photodynamic therapy (PDT)] and optical imaging under one roof. Excellent glioma-targeting ability was allocated to the nanoplatforms by conjugating them with a novel chimeric therapeutic peptide with glioma homing and antiglioma dual functionality. Further, DOX/ICG/peptide co-loaded nanoplatforms (FLDIPs) exhibited triggered drug release in response to multiple stimuli. Studies performed in 2D C6 glioma cells and 3D spheroids exhibited superior combined chemo–PDT/PTT effects (∼94% killing in cells and ∼87% in spheroids) of the designed FL based nanoplatforms compared to individual therapeutic components. Herein, the FL based multifunctional nanoplatforms with active targeting ability and stimuli responsive drug release behavior will further help in nullifying chemotherapy based adverse effects and mitigate chemo-resistance by adopting a combinatorial approach.

双血-脑屏障-胶质瘤靶向肽-聚(左旋多巴胺)混合纳米平台作为胶质母细胞瘤的潜在近红外光治疗剂

通过协同抗胶质瘤治疗来提高个体化疗法疗效的联合化疗-光疗尚处于萌芽阶段,距离有效的临床转化还有很长的路要走。在此,我们更进一步,建议采用一种简便的策略来制造智能的生物相容性和可生物降解的多功能纳米平台,该平台包括与阿霉素 (DOX) 和吲哚菁绿 (ICG) 共载的固有荧光聚(左旋多巴胺)纳米粒子(FL)。在 NIR 激光照射下设计的近红外 (NIR) 光疗剂有助于促进联合化学光疗 [光热疗法 (PTT) 和光动力疗法 (PDT)] 和光学成像在一个屋檐下。通过将纳米平台与具有神经胶质瘤归巢和抗神经胶质瘤双重功能的新型嵌合治疗肽结合,纳米平台具有出色的神经胶质瘤靶向能力。此外,DOX/ICG/肽共载纳米平台(FLDIPs)表现出响应多种刺激的触发药物释放。在 2D C6 神经胶质瘤细胞和 3D 球体中进行的研究显示,与单独的治疗成分相比,设计的基于 FL 的纳米平台具有优异的化学-PDT/PTT 组合效果(细胞杀伤率约 94%,球体杀伤率约 87%)。在此,具有主动靶向能力和刺激响应性药物释放行为的基于 FL 的多功能纳米平台将通过采用组合方法进一步帮助消除基于化疗的不良反应并减轻化疗耐药性。DOX/ICG/肽共载纳米平台(FLDIPs)表现出响应多种刺激的触发药物释放。在 2D C6 神经胶质瘤细胞和 3D 球体中进行的研究显示,与单独的治疗成分相比,设计的基于 FL 的纳米平台具有优异的化学-PDT/PTT 组合效果(细胞杀伤率约 94%,球体杀伤率约 87%)。在此,具有主动靶向能力和刺激响应性药物释放行为的基于 FL 的多功能纳米平台将通过采用组合方法进一步帮助消除基于化疗的不良反应并减轻化疗耐药性。DOX/ICG/肽共载纳米平台(FLDIPs)表现出响应多种刺激的触发药物释放。在 2D C6 神经胶质瘤细胞和 3D 球体中进行的研究显示,与单独的治疗成分相比,设计的基于 FL 的纳米平台具有优异的化学-PDT/PTT 组合效果(细胞杀伤率约 94%,球体杀伤率约 87%)。在此,具有主动靶向能力和刺激响应性药物释放行为的基于 FL 的多功能纳米平台将通过采用组合方法进一步帮助消除基于化疗的不良反应并减轻化疗耐药性。在 2D C6 神经胶质瘤细胞和 3D 球体中进行的研究显示,与单独的治疗成分相比,设计的基于 FL 的纳米平台具有优异的化学-PDT/PTT 组合效果(细胞杀伤率约 94%,球体杀伤率约 87%)。在此,具有主动靶向能力和刺激响应性药物释放行为的基于 FL 的多功能纳米平台将通过采用组合方法进一步帮助消除基于化疗的不良反应并减轻化疗耐药性。在 2D C6 神经胶质瘤细胞和 3D 球体中进行的研究显示,与单独的治疗成分相比,设计的基于 FL 的纳米平台具有优异的化学-PDT/PTT 组合效果(细胞杀伤率约 94%,球体杀伤率约 87%)。在此,具有主动靶向能力和刺激响应性药物释放行为的基于 FL 的多功能纳米平台将通过采用组合方法进一步帮助消除基于化疗的不良反应并减轻化疗耐药性。
