Common treatment protocols rely on surgical removal of tumors and chemotherapy drugs, such as paclitaxel and carboplatin, which are capable of reaching cancer cells throughout the body. However, the effectiveness of these drugs is often limited due to toxic reactions in patients, nonspecific drug distribution affecting healthy cells, and the development of treatment resistance. In this study, we introduce a polybasic nanogel system composed of poly(diethylaminoethyl methacrylate-<i>co</i>-cyclohexyl methacrylate)-<i>g</i>-poly(ethylene glycol) designed for the targeted co-delivery of paclitaxel and carboplatin directly to ovarian cancer cells. These nanogel systems can respond to the cellular microenvironment to achieve controlled, on-demand drug release, reducing off-target effects and enhancing therapeutic uptake. Additionally, we investigated nanoparticle degradation and controlled drug release as a function of various crosslinkers, including tetraethylene glycol dimethacrylate, bis(2-methacryloyl)oxyethyl disulfide, poly(lactic acid)-<i>b</i>-poly(ethylene glycol)-<i>b</i>-poly(lactic acid)dimethacrylate, and polycaprolactone dimethacrylate. Our results, using OVCAR-3 human ovarian cancer cells, demonstrated that this dual-delivery system outperformed free drugs in inducing cancer cell death, representing a promising advance in the field of nanoparticle-based therapies for ovarian cancer. By loading two chemotherapeutic agents into a single, environmentally responsive particle, this approach shows the potential to overcome common resistance mechanisms and achieve more effective tumor suppression. In summary, by delivering chemotherapy more precisely, it may be possible to enhance therapeutic outcomes while minimizing toxicity and nonspecific drug distribution, ultimately improving patient quality of life.</p>","PeriodicalId":101141,"journal":{"name":"RSC Pharmaceutics","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11843545/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143485245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, veterinary practitioners often resort to off-label use of human medications, which can lead to inconsistent patient outcomes and complications arising from inadequate dosing. Thus, there is a growing recognized need for individualized treatment strategies also within veterinary practice, as they can offer tailored doses and improved options for animal patients. To address this unmet need and overcome these challenges, our study focused on developing a once-daily dual-release tailored dose for different-sized cats and dogs utilizing semi-solid extrusion (SSE) 3D printing. The dual-release system containing different cellulosic polymers is designed to provide a rapid onset and sustained action to ensure prolonged drug release and minimize the frequency of administration. The produced printing ink formulations were successfully used to obtain different-sized tailored doses with a significant correlation between the designs and the obtained drug amounts. Dissolution studies revealed the impact of polymer combinations and tablet surface area on drug release profiles. Kinetic modeling indicated that both diffusion and erosion are involved in the release mechanisms.

GBM affects a huge population across the globe and current therapies for GBM have not proven fruitful in past decades due to poor clinical prognosis. The slow progression of GBM makes it difficult to track during diagnosis for treatment. Thus, there is a need to develop some cutting-edge drug delivery platforms, which could overcome the challenges faced in the delivery of current therapeutic drugs. Nanotechnology has been an emerging paradigm to unravel promising drug therapies, be they immunotherapy or combination therapy. The surface modification of nanocarriers led to significant improvements in therapeutic aspects of GBM. The surface-modified entities could be monoclonal antibodies, functional peptides, growth inhibitors, folic acid, transferrin, or lectins. Immunotherapeutic interventions, such as vaccines, oncolytic virotherapy, immune checkpoint inhibitors, and CAR T-cell and N-k cell therapies, are rising as a treatment model for GBM. Future research must elaborate on remedies that can encounter problems with current treatment. However, numerous research studies are underway to explore new treatments. The current review reveals potential future therapies to challenge the issues faced in the treatment of GBM. Nanotechnology-based drug carriers, surface modification of nanocarriers for enhanced drug delivery to GBM and immunotherapeutic approaches are enlisted.

The objective of this study is the development of 3D-printed drug-loaded magnetic pills with multifunctional behavior under external stimuli to be exploited for cancer therapy in hollow organs. Their construction was based on magnetic hydrogels combined with doxorubicin. Firstly, the printing fidelity was examined using two ratios of sodium alginate to carbopol (1 : 2 and 2 : 1) with two different concentrations (4 and 8 mg mL<small><sup>−1</sup></small>) of magnetic nanoparticles. The rheological measurements confirmed the material printability for preparing a 3D-printed magnetic pill in both ratios. The 3D-printed magnetic pill demonstrated strong magnetic attraction when subjected to an externally applied magnetic field confirming its ability to be remote-controlled. Thus, the magnetic component of the pills could be used for their locomotion in a targeted area using a static magnetic field, thereby increasing the residence time in a specific area of the stomach. All the prepared pills retained their morphology and shape confirming their structural integrity within a simulated gastric fluid solution (pH = 1.2). 3D-printed drug loaded magnetic and non magnetic pills were measured by applying an AC magnetic field with an amplitude of 50 mT and a frequency of 375 kHz to examine their heating ability and, consequently, the drug release. <em>In vitro</em> drug release from the 3D-printed drug-loaded magnetic pill has demonstrated a faster drug release (within 24 hours) compared with the non-magnetic 3D-printed pill. This enables a significantly localized drug release, on-demand, into the targeted area.

A model was developed to determine the kinetic rate constant of moisture sorption and desorption for different storage conditions. Dynamic vapour sorption tests revealed that excipients with higher moisture-binding capacities showed slower equilibration to the target relative humidity (RH). Elevated temperatures accelerated the moisture sorption/desorption process for all excipients, reducing the equilibrated moisture content for most, except mannitol and lactose.

All excipients reached their swelling peak within the first day of storage, with permanent particle size enlargement for CCS and SSG, whereas MCC displayed a partial reversibility post-storage.

Despite growing interest, there remain notable gaps in the understanding of the influence of plant extract concentration on the physiochemical properties of silver nanoparticles (AgNPs), particularly regarding their size.

To address this, this study explores the influence of varying <em>Spinacia oleracea</em> (<em>S. oleracea</em>) leaf extract concentrations on the physiochemical properties of AgNPs and their antimicrobial activity against Gram negative (<em>Escherichia coli</em>), Gram positive (<em>Staphylococcus aureus, Streptococcus pyogenes</em>) bacteria and Fungi (<em>Candida albicans</em>).

This study's findings will enhance understanding of this sustainable nanofabrication approach, highlighting AgNP's potential application as novel antimicrobial agents. Results confirmed spherical nanoranged AgNPs were synthesised, obtaining AgNP-2%, AgNP-3%, AgNP-4%, AgNP-7%, and AgNP-10% v/v <em>S. oleracea</em> leaf extract. Our analysis revealed a consistent trend of size reduction with increasing extract concentration: AgNP-2% (173 nm), AgNP-3% (211 nm), AgNP-4% (148 nm), AgNP-7% (120 nm), and AgNP-10% (109 nm). Regarding antimicrobial activity, the lower concentration AgNPs (AgNP-2% and AgNP-3%) showed no activity, while all the higher concentrations AgNPs displayed full inhibition of all tested microbes. In summary, our research emphasises the significance of plant extract concentration in optimising AgNP synthesis and size reduction.
