Substantial Antiviral Potential of Deoxyribozymes Fixed on Anatase Nanoparticles Against Influenza A Viruses in vitro and in vivo. J Pharm Sci 2024; 113:1202-1208. [PMID: 37879408 DOI: 10.1016/j.xphs.2023.10.028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2023] [Revised: 10/20/2023] [Accepted: 10/20/2023] [Indexed: 10/27/2023]
Abstract
Influenza A viruses (IAV) are a high threat to humanity because of a lack of proper effective antiviral drugs and resistance of viruses to existing vaccines. We describe the sufficient anti-IAV effect of Ans/PL-Dz nanocomposites that contain deoxyribozymes (Dz) immobilized on anatase TiO2 nanoparticles (Ans) through polylysine linker (PL). The Dz-containing nanocomposites appear to be more efficient than the Ans/PL-ODN nanocomposites that contain common oligodeoxyribonucleotides (ODN) targeted to the same RNA regions of the viral genome. The simultaneous use of nanocomposites that contain Dz and ODN, which are targeted to different sites of viral RNA provides a higher overall effect than the independent action of each of them (synergism). The inhibition of IAV with the proposed nanocomposites was shown to be effective, sequence-specific, and dose-dependent. The most efficient Ans/PL-Dz nanocomposite exhibited a high antiviral effect in vivo on mice models. The efficiency of IAV inhibition with this nanocomposite in vitro and in vivo is higher than that for the approved antiflu drug oseltamivir. The results open the prospect of creating a unique antiviral agent suitable for IAV suppression.

Abstract
Gold nanoparticles can produce reactive oxygen species (ROS) under the action of ultrashort pulsed light. While beneficial for photodynamic therapy, this phenomenon is prohibitive for other biomedical applications such as imaging, photo-thermal drug release, or targeted gene delivery. Here, ROS are produced in water by irradiating gold nanorods and silica-coated gold nanorods with near-infrared femtosecond laser pulses and are detected using two fluorescent probes. Our results demonstrate that a dense silica shell around gold nanorods inhibits the formation of singlet oxygen (1O2) and hydroxyl radical (˙OH) efficiently. The silica coating prevents the Dexter energy transfer between the nanoparticles and 3O2, stopping thus the generation of 1O2. In addition, numerical simulations accounting for the use of ultrashort laser pulses show that the plasmonic field enhancement at the nanoparticle vicinity is lessened once adding the silica layer. With the multiphotonic ejection of electrons being also blocked, all the possible pathways for ROS production are hindered by adding the silica shell around gold nanorods, making them safer for a range of biomedical developments.

Abstract
Gold nanorods (NRs), pseudo-one-dimensional rod-shaped nanoparticles (NPs), have become one of the burgeoning materials in the recent years due to their anisotropic shape and adjustable plasmonic properties. With the continuous improvement in synthetic methods, a variety of materials have been attached around Au NRs to achieve unexpected or improved plasmonic properties and explore state-of-the-art technologies. In this review, we comprehensively summarize the latest progress on Au NRs, the most versatile anisotropic plasmonic NPs. We present a representative overview of the advances in the synthetic strategies and outline an extensive catalogue of Au-NR-based heterostructures with tailored architectures and special functionalities. The bottom-up assembly of Au NRs into preprogrammed metastructures is then discussed, as well as the design principles. We also provide a systematic elucidation of the different plasmonic properties associated with the Au-NR-based structures, followed by a discussion of the promising applications of Au NRs in various fields. We finally discuss the future research directions and challenges of Au NRs.

TPGS/hyaluronic acid dual-functionalized PLGA nanoparticles delivered through dissolving microneedles for markedly improved chemo-photothermal combined therapy of superficial tumor. Acta Pharm Sin B 2021; 11:3297-3309. [PMID: 34729317 PMCID: PMC8546669 DOI: 10.1016/j.apsb.2020.11.013] [Citation(s) in RCA: 23] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2020] [Revised: 08/21/2020] [Accepted: 08/28/2020] [Indexed: 12/18/2022] Open
Abstract
Nanoparticles (NPs) have shown potential in cancer therapy, while a single administration conferring a satisfactory outcome is still unavailable. To address this issue, the dissolving microneedles (DMNs) were developed to locally deliver functionalized NPs with combined chemotherapy and photothermal therapy (PTT). α-Tocopheryl polyethylene glycol succinate (TPGS)/hyaluronic acid (HA) dual-functionalized PLGA NPs (HD10 NPs) were fabricated to co-load paclitaxel and indocyanine green. HD10 NPs significantly enhanced the cytotoxicity of low-dose paclitaxel because of active and mitochondrial targeting by HA and TPGS, respectively. PTT could further sensitize tumor cells toward chemotherapy by promoting apoptosis into the advanced period, highly activating caspase 3 enzyme, and significantly reducing the expression of survivin and MMP-9 proteins. Further, the anti-tumor effects of HD10 NPs delivered through different administration routes were conducted on the 4T1 tumor-bearing mice. After a single administration, HD10 NPs delivered with DMNs showed the best anti-tumor effect when giving chemotherapy alone. As expected, the anti-tumor effect was profoundly enhanced after combined therapy, and complete tumor ablation was achieved in the mice treated with DMNs and intra-tumor injection. Moreover, DMNs showed better safety due to moderate hyperthermia. Therefore, the DMNs along with combined chemo-photothermal therapy provide a viable treatment option for superficial tumors.

Abstract
The rapid development of multidrug co-delivery and nano-medicines has made spontaneous progress in tumor treatment and diagnosis. DNA is a unique biological molecule that can be tailored and molded into various nanostructures. The addition of ligands or stimuli-responsive elements enables DNA nanostructures to mediate highly targeted drug delivery to the cancer cells. Smart DNA nanostructures, owing to their various shapes, sizes, geometry, sequences, and characteristics, have various modes of cellular internalization and final disposition. On the other hand, functionalized DNA nanocarriers have specific receptor-mediated uptake, and most of these ligand anchored nanostructures able to escape lysosomal degradation. DNA-based and stimuli responsive nano-carrier systems are the latest advancement in cancer targeting. The data exploration from various studies demonstrated that the DNA nanostructure and stimuli responsive drug delivery systems are perfect tools to overcome the problems existing in the cancer treatment including toxicity and compromised drug efficacy. In this light, the review summarized the insights about various types of DNA nanostructures and stimuli responsive nanocarrier systems applications for diagnosis and treatment of cancer.

Abstract
Chemotherapy is an important anti-tumor treatment in clinic to date, however, the effectiveness of traditional chemotherapy is limited by its poor selectivity, high systemic toxicity, and multidrug resistance. In recent years, mesoporous silica nanoparticles (MSNs) have become exciting drug delivery systems (DDS) due to their unique advantages, such as easy large-scale production, adjustable uniform pore size, large surface area and pore volumes. While mesoporous silica-based DDS can improve chemotherapy to a certain extent, when used in combination with other cancer therapies MSN based chemotherapy exhibits a synergistic effect, greatly improving therapeutic outcomes. In this review, we discuss the applications of MSN DDS for a diverse range of chemotherapeutic combination anti-tumor therapies, including phototherapy, gene therapy, immunotherapy and other less common modalities. Furthermore, we focus on the characteristics of each nanomaterial and the synergistic advantages of the combination therapies. Lastly, we examine the challenges and future prospects of MSN based chemotherapeutic combination therapies.

Abstract
AbstractDeoxyribozyme (or denoted as DNAzyme), which is produced by in vitro screening technology, has gained extensive research interest in the field of biomedicine due to its high catalytic activity and structure identification. This review introduces the structural characteristics of RNA-cleaving DNAzyme and its application potential in cancer gene therapy, which plays a significant role in cancer-related gene inactivation by specifically cleaving target mRNA and inhibiting the expression of the corresponding protein. However, the low delivery efficiency and cellular uptake hindered the widespread usage of DNAzyme in gene therapy of cancers. Emerging nanotechnology holds great promise for DNAzyme to overcome these obstacles. This review mainly focuses on DNAzyme-based nanotherapeutic platforms in gene therapy of cancers, including oncogene antagonism therapy, treatment resistance gene therapy, immunogene therapy, and antiangiogenesis gene therapy. We also revealed the potential of DNAzyme-based nanotherapeutic platforms as emerging cancer therapy approaches and their security issues.

Abstract
Plasmon-enhanced gold nanorod (AuNR) with high photothermal conversion efficiency is a promising light-controllable nanodrug delivery system for cancer therapy. Understanding the mechanism for the light-controllable drug release of AuNR delivery systems is important for the development of nanomedicine. In this study, the rhodamine B (RB) released from AuNR-RB nanodelivery system was quantitated and visualized by using two-photon luminescence (TPL) imaging combined with correlation spectroscopy. The photofragmentation of AuNR induced by femtosecond pulsed laser was revealed by TPL correlation spectroscopy when the laser energy was above the thermal damage threshold of AuNR, and the RB released from this nanodrug delivery system was visualized by TPL imaging. Furthermore, the photofragmentation-induced release of RB from AuNR-RB nanodelivery system was visualized in living MCF-7 breast cancer cells by TPL imaging combined with correlation spectroscopy. These results provided a novel optical approach to quantify the release of drugs from gold nanocarriers in complex biological media.

Abstract
Chemotherapy is an effective method for treating cancer, clinically. However, side effects of drug and multidrug resistance restrict its application. In recent years, the combined treatment of chemotherapy and photothermal therapy (PTT) is becoming a promising method for treating cancer. PTT utilizes nanomaterials absorbing near-infrared light and producing heat to acquire advanced hyperthermia strategy for cancer treatment. Carbon nanomaterials with good biocompatibility, high surface area, and excellent photothermal properties are an excellent nanoplatform for drug delivery and PTT. Herein, porous carbon-coated magnetite nanoparticles (PCCMNs) were successfully synthesized by a one-pot solvothermal method. Magnetite, a contrast agent, can be used for magnetic resonance imaging. Hyaluronic acid was used to modify the PCCMNs to achieve targeted therapy. The obtained nanohybrid with a good photothermal effect can realize combined PTT/chemotherapy and will be a promising nanoplatform for high efficacy theranostics.
