Embedding Diselenide Cross-Linked Polymer Nanoparticles In-Situ Using Ring-Opening Metathesis Polymerization (Romp) of Norbornene Derived Block Copolymers for Ros-Responsive Doxorubicin (Dox) Drug Delivery

作者： Rao, Neralla Vijayakameswara Mathew, Jacob Le, Trong-Nghia Lee, Cheng-Kang Huang, Ru Department of Chemical Engineering National Taiwan University of Science and Technology Taipei Taiwan School of Pharmacy College of Pharmacy Taipei Medical University Taipei Taiwan Ph.D. Program in Drug Discovery and Development Industry College of Pharmacy Taipei Medical University Taipei Taiwan National Taiwan University of Science and Technology Taiwan

Norborene-derived block polymers with selenol-containing components and norbornene-polyethylene (PNEG) components are proposed for the development of diselenide-crosslinked polymer nanoparticles (DC PNPs), in situ, which are responsive to the abnormal ROS levels in the tumoral region, as anticancer drug carriers. These nanoparticles can be designed to release anticancer drugs selectively in the tumor microenvironment, minimizing systemic toxicity and enhancing therapeutic efficacy. The diselenide bonds in the polymer degrade in response to high levels of reactive oxygen species (ROS), which are characteristic of cancerous tissues, thereby releasing the drug at the target site. In micelles, doxorubicin (DOX) is effectively encapsulated in the hydrophobic core and the shell is strengthened by diselenide crosslinks (DOX- DC PNPs). A DLS particle stability study demonstrated that structural integrity was maintained for three days under physiological conditions. However, the hydrophobic diselenide bond successfully fragmented into hydrophilic selenic acid derivatives under ROS conditions, leading to the release of the payload from the drug-containing matrix. Validation of the drug release showed that 52% of the payload was released at a H2O2 concentration of 10 µM, ensuring the reactive matrix reaction;s optimal accuracy. A toxicity study on a normal cell line (L929) confirmed the polymer's biocompatibility, while the encapsulated model exhibited significant toxicity to a cancer cell line (Hela). In contrast to free DOX, DOX-loaded polymer nanoparticles (PNPs) displayed a lower toxicity threshold, attributed to their capacity for gradual drug release over time. Furthermore, a comparison of cellular uptake reveals that while free DOX provides immediate drug availability, DOX loaded PNPs offer a more controlled and sustained release mechanism. In cancer therapy, this characteristic enhances therapeutic efficacy while minimizing side effects associated with high concentrati

The passivation ability of steels with low chromium contents (4% and 6%) in a solution representative of carbonated-cured concrete matrices was compared to conventional carbon steel rebars. Samples were investigated through multiple electrochemical methods, and the passive film was evaluated using x-ray photoelectron spectroscopy. Results showed that carbon steel rebars are vulnerable to corroding in carbonated-cured pore solutions, while the low chromium showed spontaneous, rapid and effective passivation. The study demonstrated the possibility of producing tailored low chromium steels as a durable alternative to carbon steel while being more affordable than stainless steel, contributing to more sustainable, innovative reinforced concretes. © 2023, The Authors.

Until recently, sorafenib has been the only treatment approved by the U.S. Food and Drug Administration for patients with advanced hepatocellular carcinoma (HCC). Some patients, however, exhibit resistance to this treatment and subsequently experience cancer progression, recurrence, or death. Therefore, identifying a new alternative treatment for patients with little or no response to sorafenib treatment is vital. In this study, we explored the therapeutic potential and underlying molecular mechanism of antrocinol ((3aS,4R,6aS,10aR)-4-(hydroxymethyl)-7,7-dimethyldecahydro-1H-naphtho[1,8a-c]furan-1-one) in patients with HCC. The results indicated that antrocinol was more therapeutically effective than antrocin, Stivarga, and sorafenib against HCC cell lines. Antrocinol also substantially suppressed the expression of KRAS-GTP, p-MEK1/2, p-ERK1/2, and p-AKT in the Huh7 cell line. Additionally, antrocinol-induced apoptosis in the Huh7 cell line, inhibited the formation of tumorspheres, and suppressed the expression of cancer stem cell markers CD133, KLF4, CD44, OCT4, SOX2, and c-Myc. Animal studies revealed that antrocinol alone considerably suppressed tumor growth in nonobese diabetic/severe combined immunodeficient mice inoculated with Huh7 tumorspheres. It also synergistically enhanced the anticancer effect of sorafenib, resulting in enhanced suppression of tumor growth (p < 0.001) and tumorsphere formation (p < 0.001). In tumor samples resected from mice treated with antrocinol alone or in combination with sorafenib, immunohistochemical analysis revealed an increase in BAX expression and a decrease in ERK and AKT protein expression. To the best of our knowledge, this is the first report of the anti-HCC activity of antrocinol. With its higher therapeutic efficacy than that of sorafenib, antrocinol is a candidate drug for patients with HCC who demonstrate little or no response to sorafenib treatment. © 2022 Elsevier B.V.

The increasing environmental concerns over and demand for sustainable solutions have driven research into the efficient recovery and reuse of waste materials, particularly from photocatalysts used in wastewater treatment. This study addresses the critical challenge posed by used PVDF/TiO2 photocatalysts, which, if not properly managed, contribute to environmental pollution. A practical recovery technique based on the phase inversion method was developed to separate and purify PVDF, TiO2, and the solvent NMP from used composite materials. This method led to recovery rates of 95.17% for PVDF, 98.35% for NMP, and 67% for TiO2. The recycled photocatalyst was then reassembled and tested for its ability to degrade methylene blue, a common dye pollutant. A Box–Behnken design was employed to optimize the treatment conditions, ensuring the process was both efficient and reproducible. The regenerated material achieved up to 99.6% efficiency in the first cycle, with a slight reduction in efficiency observed across subsequent cycles, maintaining over 92% efficiency after 10 cycles. These findings confirm that effective recovery of photocatalytic materials is not only feasible but also beneficial in reducing waste and maintaining high treatment performance.

Progress in Natural science:Materials International 2018年第2期28卷 121-132页

Recent development in nanoscience and nanotechnology has opened up new frontiers in materials science and engineering to create new materials for energy generation and storage. Owing to their earth abundance, lowcost, structural tunability, large-surface area, and unique physicochemical properties, graphitic carbon materials have attracted a great deal of attention for energy-related applications. However, the pristine graphene materials without functionalization is intractable(insoluble and infusible), which has hindered their practical applications. Therefore, considerable research effort has been devoted to the development of functionalized graphene materials with desirable properties for specific applications, including energy conversion and storage. It was demonstrated that functionalized graphene materials with tunable work functions were useful as charge-extraction materials to effectively improve solar cell performance while those with high electrocatalytic activities could be used as metal-free catalysts in fuel cells, metal-air batteries, water splitting and integrated energy systems. This article provides a timely focused review on the development of heteroatom-doped graphene materials for low-cost, but efficient, energy generation and storage.
