Int J Biol Macromol 2024; 258:128691. [PMID: 38072344 DOI: 10.1016/j.ijbiomac.2023.128691] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2023] [Revised: 12/03/2023] [Accepted: 12/07/2023] [Indexed: 01/06/2024]
Abstract
The effective delivery and targeted release of drugs within tumor cells are critical factors in determining the therapeutic efficacy of nanomedicine. To achieve this objective, a conjugate of maltose (Mal) and bovine serum albumin (BSA) was synthesized by the Maillard reaction and self-assembled into nanoparticles with active-targeting capabilities upon pH/heating induction. This nanoparticle could be effectively loaded with doxorubicin (DOX) to form stable nanodrugs (Mal-BSA/DOX) that were sensitive to low pH or high glutathione (GSH), thereby achieving a rapid drug release (96.82 % within 24 h). In vitro cell experiments indicated that maltose-modified BSA particles efficiently enhance cellular internalization via glucose transporters (GLUT)-mediated endocytosis, resulting in increased intracellular DOX levels and heightened expression of γ-H2AX. Consequently, these results ultimately lead to selective tumor cells death, as evidenced by an IC50 value of 3.83 μg/mL in HepG2 cells compared to 5.87 μg/mL in 293t cells. The efficacy of Mal-BSA/DOX in tumor targeting therapy has been further confirmed by in vivo studies, as it effectively delivered a higher concentration of DOX to tumor tissue. This targeted delivery approach not only reduces the systemic toxicity of DOX but also effectively inhibits tumor growth (TGI, 75.95 %). These findings contribute valuable insights into the advancement of targeting-albumin nanomedicine and further support its potential in tumor treatment.

Abstract
To enhance the stability of the polymeric micelles and optimize their drug-controlled release ability, three disulfide-linked polyethylene glycol methyl ether methacrylate-disulfide-poly(ε-caprolactone-co-γ-amine-ε-caprolactone) (PPEGMA-SS-P(CL-co-ACL)) polymers were synthesized and characterized by 1H NMR, GPC, and FT-IR successfully, and their dual pH/reduction-responsive cross-linked polymeric micelles were prepared for paclitaxel (PTX) delivery by using 2,3-dimethylmaleic anhydride (DMMA) as the cross-linking agent. The PTX loading capacity (LC) and encapsulation efficiency (EE) values of the cross-linked micelles formed by PPEGMA8-SS-P(CL47-co-ACL15) achieved were 23.96% and 71.58%, slightly higher than those of un-cross-linked micelles. Both particle sizes of blank micelles and in vitro drug release of PTX-loaded micelles confirmed that compared with those un-cross-linked micelles, the cross-linked micelles were more stable at pH 7.4 + 0 mM DTT, with a PTX cumulative release of 13% at 120 h, while the PTX cumulative release of the cross-linked micelles at pH 5.0 + 10 mM DTT were close to that of un-cross-linked micelles after 60 h, indicating the successful reversible cross-linking and smooth drug release of the cross-linked micelles. The cytotoxicity assay showed that PPEGMA8-SS-P(CL47-co-ACL15) and its cross-linked micelles had low cell cytotoxicity, and both PTX-loaded micelles revealed a certain inhibitory effect on HepG2 cells. These results revealed that the dual pH/reduction-responsive cross-linked polymeric micelles prepared from PPEGMA8-SS-P(CL47-co-DCL15) were a promising candidate for PTX delivery.

Abstract
Poorly soluble drug molecules/phytoconstituents are still a growing concern for biopharmaceutical delivery in the body. Polymeric micelles are the amphiphilic block copolymers and have been widely investigated as targeted nanocarriers for the treatment of various ailments. The versatility of nanocarriers is the self-assembling properties in the aqueous medium and forms a stable isotropic system in vivo. The hydrophobic core-hydrophilic shell configuration of the polymers used to the mixed micelles makes easy encapsulation of hydrophobic and hydrophilic drugs into the core. Polymeric micelles can also be combined with targeting ligands that increase their uptake by specific cells, decreasing off-target effects, and provide enhanced therapeutic effect. In the present review, we primarily focused on a critical appraisal of Polymeric micelles along with the method of preparation, mechanism of micelle formulation, and the ongoing formulations under clinical trials. In addition, the biological applications of this isotropic nanocarrier have been duly presented in each route of administration along with suitable case studies.

Abstract
Hybrid smart emulsification systems are highly applicable in manipulating oil-in-water (O/W) droplets. Herein, novel switchable block polymers containing both zwitterionic and tertiary amine pendent groups were designed and synthesized to combine with charged silica particles to stabilize the O/W emulsion responsive to pH. This study was carried out in O/W emulsions stabilized with the polymer and silica particles under different pH conditions. The emulsion system was also simulated using molecular dynamics simulation to reveal the mechanism at molecular levels, thus gaining insight into the relationships between the emulsifying properties and the molecular interaction of the mixed system. Upon acidification of the continuous aqueous phase, protonated polymers with excellent hydrophilicity were induced by charged silica particles to cause rapid emulsion coalescence. In alkaline media, the mixed system conversely stabilized the O/W emulsions, cutting polymer consumption by over three-quarters. The emulsification and demulsification can be switched alternately by tuning the pH conditions. The applications exhibited excellent efficiency in separating heavy oil/water emulsions and proved the high conversion rate in emulsion polymerization. Overall, with this novel strategy to relieve tedious modifications on particle surfaces and massive consumption of polymers, the designed responsive emulsification systems can impart intelligent and controllable chemical reactivity to emulsions on demand in a more affordable and sustainable way.

Abstract
How to enhance the bioavailability and prolong the residence time of drugs in the eye present the major barriers to traditional eye delivery. Nanotechnology has been widely used in ocular drug delivery systems because of its advantages of minimizing adverse reactions, decreasing the frequency of administration, prolonging the release time, and improving the bioavailability of the drug in the eye. As natural product-based nanostructured systems, bioinspired nanostructured systems have presented as less toxic, easy to prepare, and cost-effective and have potential application value in the field of nanotechnology. A systematic classification of bioinspired nanostructured systems based on their inspiration source and formulation and their brief applications in disease are presented here. A review of recent research progress of the bioinspired nanostructured systems for the treatment of the anterior and posterior segment of ocular disorders is then presented in detail. Finally, current challenges and future directions with regard to manufacturing bioinspired nanomaterials are provided.
