Abstract

Medicine treatments for bone-related diseases such as osteoporosis, bone metastasis, osteomyelitis, and osteolysis are often limited by insufficient drug concentration at the lesion sites owing to the low perfusion of bone tissue. A carrier that can deliver multiple bone destruction site-targeting drugs is required to address this limitation. Here, we reported a novel bone-targeting nano-drug delivery platform formed by the integration of zoledronate (ZOL) and zeolitic imidazolate framework-8 (ZIF-8) nanoparticles. The ZOL mixed zeolitic imidazolate framework (ZZF) nanoparticles were synthesized in water at room temperature (25 °C), where many biomacromolecules could maintain their activity. This allowed the ZZF nanoparticles to adapt the encapsulation ability and pH response release property from ZIF-8 and the excellent bone targeting performance of ZOL simultaneously. Considering the ease of preparation and biomacromolecule-friendly drug delivery of this nano platform, it may be useful in treating bone-related diseases.

摘要

用于治疗骨质疏松症、骨转移、骨髓炎和溶骨性疾病等骨骼相关疾病的药物治疗往往受到骨骼组织灌注不足导致病变部位药物浓度不足的限制。需要一种能够输送多种骨破坏部位靶向药物的载体来解决这一限制。在这里,我们报道了一种新型的骨靶向纳米药物递送平台,该平台由唑来膦酸(zoledronate,ZOL)和沸石咪唑酯骨架-8(zeolitic imidazolate framework-8,ZIF-8)纳米颗粒的整合形成。ZOL 混合沸石咪唑酯骨架(ZIF-8)纳米颗粒在室温(25°C)的水中合成,在这种条件下,许多生物大分子可以保持其活性。这使得 ZZF 纳米颗粒能够同时适应 ZIF-8 的封装能力和 pH 响应释放特性,以及 ZOL 的优异的骨骼靶向性能。考虑到该纳米平台易于制备和对生物大分子友好的药物传递特性,它可能对治疗骨骼相关疾病有用。
