Antibiotic therapy is the routine method for treating bacterial infections and has saved hundreds of millions of lives over the last century. However, low bioavailability, side effects, and emergence of antibiotic-resistant bacteria are usually associated with the systemic administration of antibiotics. Polymer-based antibiotic delivery system (PADS), as a solution to the limitations of conventional antibiotic therapy, has received significant attention, for it is able to protect antibiotics from premature metabolism and optimize the pharmacokinetics. Moreover, PADS can be elaborately modified to target the infection sites through the specific ligand-receptor interactions in an active manner, or through the responses to endogenous and exogenous stimuli in a passive manner. Multiple polymeric nano-constructions have been used thus far to fabricate PADS, such as polymeric liposomes, polymeric micelles, highly branched polymers and dendrimers, and polymeric nanogels, exhibiting enhanced therapeutic effects compared with the corresponding free antibiotics. In addition, hybrid nanoplatforms integrating the inorganic or biological components have also been developed for PADS, which have the potential to achieve complementary and synergistic effects with antibiotic therapy. In this paper, we reviewed the advances that have been made in PADS for the treatment of bacterial infections in the past five years, highlighting the design principles and targeting capability, in an attempt to provide new insights for further researches.

基于聚合物的靶向抗生素递送系统:通过大分子方法治疗细菌感染的有前途的选择

抗生素疗法是治疗细菌感染的常规方法,在上个世纪已挽救了数亿人的生命。然而,低生物利用度,副作用和抗生素抗性细菌的出现通常与抗生素的全身给药有关。基于聚合物的抗生素递送系统(PADS)作为解决常规抗生素疗法局限性的解决方案,受到了广泛的关注,因为它能够保护抗生素免于过早代谢并优化药代动力学。此外,PADS可以经过精心修饰,以主动方式通过特异性配体-受体相互作用,或通过被动方式响应内源性和外源性刺激,从而靶向感染部位。迄今为止,已经使用多种聚合物纳米结构来制造PADS,例如聚合物脂质体,聚合物胶束,高度支化的聚合物和树状聚合物以及聚合物纳米凝胶,与相应的游离抗生素相比,它们具有增强的治疗效果。此外,还开发了整合了无机或生物成分的杂化纳米平台用于PADS,具有与抗生素疗法取得互补和协同作用的潜力。在本文中,我们回顾了过去五年PADS在细菌感染治疗方面取得的进展,重点介绍了设计原理和靶向能力,旨在为进一步的研究提供新的见识。和聚合物纳米凝胶,与相应的游离抗生素相比,具有增强的治疗作用。此外,还开发了整合了无机或生物成分的杂化纳米平台用于PADS,具有与抗生素疗法取得互补和协同作用的潜力。在本文中,我们回顾了过去五年PADS在细菌感染治疗方面取得的进展,重点介绍了设计原理和靶向能力,旨在为进一步的研究提供新的见识。和聚合物纳米凝胶,与相应的游离抗生素相比,具有增强的治疗作用。此外,还开发了整合了无机或生物成分的杂化纳米平台用于PADS,具有与抗生素疗法取得互补和协同作用的潜力。在本文中,我们回顾了过去五年PADS在细菌感染治疗方面取得的进展,重点介绍了设计原理和靶向能力,旨在为进一步的研究提供新的见识。它们有可能与抗生素治疗取得互补和协同作用。在本文中,我们回顾了过去五年PADS在细菌感染治疗方面取得的进展,重点介绍了设计原理和靶向能力,旨在为进一步的研究提供新的见识。它们有可能与抗生素治疗取得互补和协同作用。在本文中,我们回顾了过去五年PADS在细菌感染治疗方面取得的进展,重点介绍了设计原理和靶向能力,旨在为进一步的研究提供新的见识。
