A new theranostic nanoplatform, comprising of monodisperse zirconium metal-organic frameworks (MOFs) as drug carriers and carboxylatopillar[5]arene-based supramolecular switches as gating entities, is constructed, and controlled drug release triggered by bio-friendly Zn(2+) ions (abundant in synaptic vesicles) and auxiliary thermal stimulus is realized. This on-command drug delivery system exhibits large pore sizes for drug encapsulation, excellent biodegradability and biocompatibility, extremely low cytotoxicity and premature drug release, and superior dual-stimuli responsiveness, opening a new avenue in targeted drug delivery and controlled release of therapeutic agents, especially in the treatment of central nervous system diseases.
构建了一种新的治疗性纳米平台,由单分散的锆金属-有机骨架(MOFs)作为药物载体和基于羧酸柱[5]芳烃的超分子开关作为门控实体组成,并实现了由生物友好的 Zn(2+)离子(突触小泡中丰富)和辅助热刺激触发的控制药物释放。这种按需药物输送系统具有用于封装药物的大孔径、优异的生物降解性和生物相容性、极低的细胞毒性和过早的药物释放以及卓越的双重刺激响应性,为靶向药物输送和治疗剂的控制释放开辟了新途径,特别是在治疗中枢神经系统疾病方面。
