Abstract

Within the general context of nanomedicine, drug delivery systems based on polymers have sparked a rapidly growing interest and raised many efforts to tackle various diseases, among which cancer. Polyester-based nanoparticulate drug delivery systems, including polymer-drug conjugates and amphiphilic block copolymers, represent a major class with promising outcomes, especially for those derived from poly(3-hydroxybutyrate) (PHB). This review describes recent advances in drug delivery systems designed from the self-assembly of synthetic (co)polymers derived from PHB. The various strategies for the synthesis of PHB-conjugates, PHB/poly(ethylene glycol) (PEG) and other PHB-based copolymers are first summarized. Nanoparticles, micelles, microparticles, and hydrogels elaborated from these (co)polymers following various preparation methods, along with their exploitation in the encapsulation and release of various therapeutic agents, are next detailed. Finally, we discuss the synthetic challenges, drug delivery outlooks, and perspectives of PHB-based drug delivery systems. Engineered nano-scaled materials based on PHB self-assembled systems are thus anticipated to emerge as a valuable platform for original drug delivery systems.
