AI Article Synopsis
- Curcumin-loaded microspheres were created using a one-step emulsification method, combining α-isobutyl cyanoacrylate, poloxamer 188, and curcumin complexed with hydroxypropyl-β-cyclodextrin.
- As the concentration of emulsifier increased, the size of the microspheres decreased while drug loading and encapsulation efficiency improved, with an optimal emulsifier concentration identified at 0.05%.
- Higher concentrations of curcumin increased drug loading but decreased encapsulation efficiency; moreover, increased drug loading led to a lower cumulative release percentage, suggesting better wettability and bioavailability of the drug.
Article Abstract
Curcumin-loaded poly (α-isobutyl cyanoacrylate) microspheres (Cur-HP-β-CD-PiBCA) were prepared by one-step emulsification with α-isobutyl cyanoacrylate as materials, poloxamer 188 as emulsifier, and curcumin complex with hydroxypropyl-β-cyclodextrin (Cur-HP-β-CD) as drug prepared by kneading method. Effects of emulsifier and drug concentration on microspheres size and distribution, drug loading and encapsulation efficiency were investigated in detail. And the curcumin release of drug-loaded microspheres was also studied. Results showed that as the emulsifier concentration increased from 0.01% to 0.07%, particle size of the drug-loaded microspheres decreased while particle size distribution, drug loading and entrapment efficiency increased. The optimized concentration of surfactant was 0.05%. With increasing the concentration of drug from 0.03% to 0.07%, drug loading of Cur-HP-β-CD-PiBCA increased, but encapsulation efficiency decreased. Additionally, the results of drug release experiments revealed that the higher drug loading of Cur-HP-β-CD-PiBCA was, the lower cumulative release percentage was. Drug-loading of cumulative inclusions in HP-β-CD by PiBCA can improve its wettability, and increase the degree of dissolution and bioavailability.

Despite significant progress in cancer treatment, traditional therapies still face considerable challenges, including poor targeting, severe toxic side effects, and the development of resistance. Recent advances in biotechnology have revealed the potential of bacteria and their derivatives as drug delivery systems for tumor therapy by leveraging their biological properties. Engineered bacteria, including , , and , along with their derivatives─outer membrane vesicles (OMVs), bacterial ghosts (BGs), and bacterial spores (BSPs)─can be loaded with a variety of antitumor agents, enabling precise targeting and sustained drug release within the tumor microenvironment (TME).

Carrier-free nanomedicines exhibited significant potential in elevating drug efficacy and safety for tumor management, yet their self assembly typically relied on chemical modifications of drugs or the incorporation of surfactants, thereby compromising the drug's inherent pharmacological activity. To address this challenge, we proposed a triethylamine (TEA)-mediated protonation-deprotonation strategy that enabled the adjustable-proportion self assembly of dual drugs without chemical modification, achieving nearly 100% drug loading capacity. Molecular dynamic simulations, supported by experiment evidence, elucidated the underlying self-assembly mechanism.
