Pharmacol Res 2022; 176:106080. [PMID: 35032663 DOI: 10.1016/j.phrs.2022.106080] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/27/2021] [Revised: 01/03/2022] [Accepted: 01/10/2022] [Indexed: 02/06/2023]
Abstract
Combination therapy system has become a promising strategy for achieving favorable antitumor efficacy. Herein, a novel oral drug delivery system with colon localization and tumor targeting functions was designed for orthotopic colon cancer chemotherapy and photothermal combinational therapy. The polydopamine coated nanodiamond (PND) was used as the photothermal carrier, through the coupling of sulfhydryl-polyethylene glycol-folate (SH-PEG-FA) on the surface of PND to achieve systematic colon tumor targeting, curcumin (CUR) was loaded as the model drug, and then coated with chitosan (CS) to achieve the long gastrointestinal tract retention and colon localization functions to obtain PND-PEG-FA/CUR@CS nanoparticles. It has high photothermal conversion efficiency and good photothermal stability and exhibited near-infrared (NIR) laser-responsive drug release behavior. Folate (FA) modification effectively promotes the intracellular uptake of nanoparticles by CT26 cells, and the combination of chemotherapy and photothermal therapy (CT/PTT) can enhance cytotoxicity. Compared with free CUR group, nanoparticles prolonged the gastrointestinal tract retention time, accumulated more in colon tumor tissues, and exhibited good photothermal effect in vivo. More importantly, the CT/PTT group exhibited satisfactory tumor growth inhibition effects with good biocompatibility in vivo. In summary, this oral drug delivery system is an efficient platform for chemotherapy and photothermal combinational therapy of orthotopic colon cancer.

Abstract
This review discusses, in brief, the various synthetic methods of two widely-used nanofillers; phyllosilicate and graphene. Both are 2D fillers introduced into hydrogel matrices to achieve mechanical robustness and water uptake behavior. Both the fillers are inserted by physical and chemical gelation methods where most of the chemical gelation, i.e., covalent approaches, results in better physical properties compared to their physical gels. Physical gels occur due to supramolecular assembly, van der Waals interactions, electrostatic interactions, hydrophobic associations, and H-bonding. For chemical gelation, in situ radical triggered gelation mostly occurs.

Abstract
Self-assembled nucleo-peptide hydrogels have a nanofibril structure composed of noncovalent molecular interactions between peptide groups as well as π-π stacking and Watson-Crick interactions via complementary nucleobases. These hydrogels have specific benefits for biomedical applications due to their DNA-like interactions in addition to the well-known advantages of peptide biomaterials: biocompatibility, extracellular matrix (ECM)-like structure, and bottom-up design. Inspired by the nucleobase stacking structure, we hypothesized that nucleo-peptides would be able to deliver the DNA-intercalating chemotherapeutic, doxorubicin (Dox) in a sustained manner when delivered locally to a solid tumor. Ade-FFF nucleo-peptide hydrogels were able to load a high concentration of Dox (1 mM) and demonstrated continuous release under in vitro degradation conditions. We adopted an in vivo tumor-bearing mouse model to evaluate the delivery of Dox by Ade-FFF hydrogels. We found that Dox-containing hydrogels reduced tumor growth and resulted in greater apoptosis-mediated cell death in the tumor as evidenced by caspase-3 expression. Pharmacokinetics and biodistribution studies also supported the observation that Dox delivery by an Ade-FFF hydrogel improves sustained delivery in the local tumor site. This study demonstrates the potential of self-assembled nucleo-peptides in biomedical applications by using their distinctive DNA-like structure.

Abstract
Due to the unique structural and mechanical properties, graphene quantum dots (GQDs) are considered as potential candidates in the field of biosensors, bioimaging, and drug delivery etc. In this work, the adsorption of protein villin headpiece (HP35) on GQDs with different sizes was investigated by molecular dynamics simulations. The simulation results identified the key role of the π-π stacking interactions between the aromatic residues of HP35 and GQDs as the binding site. More importantly, with the increase of GQD size, the amount and binding strength of adsorbed residues increase, and sequentially enhance the structure change of adsorbed protein, verified by various analysis of protein structures etc. These findings may improve the understanding of the cytotoxicity and biosafety of GQDs, and hence promote the design and application of GQDs-based biomedical devices.

Aim: To build up a remote triggering drug delivery system with hyperthermia-responsive ammonium bicarbonate salt and investigate its effects on tumor therapy. Materials & methods: This hybrid nanocapsule system was prepared by a different strategy, doxorubicin (DOX) was encapsulated in the heparin shell first and then ammonium bicarbonate was diffused into the nanocapsules to generate DOX-bicarbonate salt, its characterizations and effects on tumor therapy were investigated. Results: Upon exposure to mild external thermal treatment (42°C), DOX-bicarbonate salt began to decompose with the recovery of DOX fluorescence, carbon dioxide generation and rapid DOX release out of the nanocapsules, exhibiting great abilities to accumulate at tumor site rapidly and inhibit tumor cell growth. Conclusion: These hybrid nanocapsules demonstrate great potential in clinical applications triggering by external thermal treatment.

Abstract
Owing to unique morphology, ultrasmall lateral sizes, and exceptional properties, graphene quantum dots (GQDs) hold great potential in many applications, especially in the field of electrochemical biosensors, bioimaging, drug delivery, et cetera. Its biosafety and potential cytotoxicity to human and animal cells has been a growing concern in recent years. In this work, the potential cytotoxicity of GQDs was evaluated by molecular dynamics simulations. Our simulation demonstrates that small size GQDs could easily permeate into the lipid membrane in a vertical way. It is relatively difficult to permeate into the lipid membrane for GQDs that are larger than GQD61 on the nanosecond time-scale. The thickness of the POPC membrane could even be affected by the small size of GQDs. Free energy calculations revealed that the free energy barrier of GQD permeation through the lipid membrane could greatly change with the change of GQD size. Under high GQD concentration, the GQD molecules could rapidly aggregate in water but disaggregate after entering into the membrane interior. Moreover, high concentrations of GQDs could induce changes in the structure properties and diffusion properties of the lipid bilayer, and it may affect the cell signal transduction. However, GQDs with relatively small size are not large enough to mechanically damage the lipid membrane. Our results suggest that the cytotoxicity of GQDs with small size is low and may be appropriate for biomedical application.

Abstract
The co-delivery of drug and gene has become the primary strategy in cancer therapy. However, to construct one safe co-delivering system with higher drug loading and gene transfection efficiency for cancer therapy is still challenging. Herein, a novel degradable nanocarriers were synthesized and characterized in this study, which was composed of polyethylenimine (PEI)-linked PEO-PPO-PEO (Pluronic F127), called F127-PEI. Then the nanocarrier was used for hydrophobic docetaxel (DOC) and functional gene (TFPI-2 plasmid) co-delivery to treat nasopharyngeal cancer (NPC). The results indicated that F127-PEI nanocarriers had higher DOC loading amount and possessed good gene delivery effect in vitro. For co-delivery analysis, the obtained F127-PEI/DOC/TFPI-2 complexes could induce a more significant apoptosis than DOC or TFPI-2 alone, and decreased invasive capacity of NPC HNE-1 cells more obviously. Moreover, the F127-PEI copolymer exhibited better blood compatibility and lower cytotoxicity compared to PEI-25k by the hemolysis and MTT assays, which suggests a promising potential for NPC therapy.
