Polymer-on-HOF: a new strategy for fabricating “armour-plated” HOFs to sequester radioactive anions

引用

Science China Chemistry 2024年第9期67卷 2958-2967页

作者： Hai-Ruo Li Shitao wu Xuezhuo Jing Zhengyi Di kun Liu Lu Wang Cheng-Peng Li Zhong Liu Miao Du College of Chemistry Tianjin Key Laboratory of Structure and Performance for Functional Molecules Tianjin Normal University Shanghai Key Laboratory of High-Resolution Electron Microscopy School of Physical Science and Technology Shanghai Tech University Key Laboratory of Comprehensive and Highly Efficient Utilization of Salt Lake Resources Qinghai Provincial Key Laboratory of Resources and Chemistry of Salt Lakes Qinghai Institute of Salt Lakes Chinese Academy of Sciences College of Material and Chemical Engineering Institute of New Energy Science and Technology School of Future Hydrogen Energy Technology Zhengzhou University of Light Industry

The development of hydrogen-bonded organic frameworks（HOFs） faces significant constraints, primarily attributed to their fragile architectures and limited functionalization capabilities. To overcome these limitations, this work presents a new polymeron-HOF strategy by covalently tethering armor-like polymers onto the surface of HOFs. The application of this approach not only bolsters the stability of HOFs, but also facilitates the customization of their functional expansion in radionuclide sequestration. The optimized HOF-polymer materials display extraordinary ability in radionuclide sequestration, achieving uptake of I–(0.699 g g–1), IO3–(0.285 g g–1) and ReO4–(1.616 g g–1, setting a world record), fast adsorption kinetics（～100% removal within 45 s）, and exceptional regeneration capability（>30 cycles） under continuous flow conditions. These outstanding performances benefit from the internal porous channels and surface imidazolium polymer coatings of HOFs, as proved by density functional theory calculation and molecular dynamics simulations. This work paves the way for the rational design of HOF-based hybrid materials tailored to versatile applications.

Pyrimethamine upregulates BNIP3 to interfere SNARE-mediated autophagosome-lysosomal fusion in hepatocellular carcinoma

引用

Journal of Pharmaceutical Analysis 2024年第2期14卷 211-224页

作者： Jingjing Wang Qi Su kun Chen Qing wu Jiayan Ren Wenjuan Tang Yu Hu Zeren Zhu Cheng Cheng Kaihui Tu Huaizhen He yanmin Zhang School of Pharmacy Health Science CenterXi'an Jiaotong UniversityXi'an710061China

Hepatocellular carcinoma (HCC) is one of the most common tumor types and remains a major clinical challenge. Increasing evidence has revealed that mitophagy inhibitors can enhance the effect of chemotherapy on HCC. However, few mitophagy inhibitors have been approved for clinical use in humans. Pyrimethamine (Pyr) is used to treat infections caused by protozoan parasites. Recent studies have reported that Pyr may be beneficial in the treatment of various tumors. However, its mechanism of action is still not clearly defined. Here, we found that blocking mitophagy sensitized cells to Pyr-induced apoptosis. Mechanistically, Pyr potently induced the accumulation of autophagosomes by inhibiting autophagosome-lysosome fusion in human HCC cells. In vitro and in vivo studies revealed that Pyr blocked autophagosome-lysosome fusion by upregulating BNIP3 to inhibit synaptosomal-associated protein 29 (SNAP29)-vesicle-associated membrane protein 8 (VAMP8) interaction. Moreover, Pyr acted synergistically with sorafenib (Sora) to induce apoptosis and inhibit HCC proliferation in vitro and in vivo. Pyr enhances the sensitivity of HCC cells to Sora, a common chemotherapeutic, by inhibiting mitophagy. Thus, these results provide new insights into the mechanism of action of Pyr and imply that Pyr could potentially be further developed as a novel mitophagy inhibitor. Notably, Pyr and Sora combination therapy could be a promising treatment for malignant HCC.

Securing a comfortable, wearable compact frequency beam scanning antenna(FBSA) with robustness to deformation, low specific absorption rate(SAR), and good coverage of the surrounding environment for Internet of Things(IoT) applications, such as on-body navigation and wireless communication is an emerging challenge. In this work, a robust textile-based spoof plasmonic frequency scanning antenna utilizing higher-order modes is presented, which is also robust to deformation caused by the activities of the human body. The innovative design of the element ensures the high-efficiency transmission of the fundamental mode of spoof surface plasmon polaritons(SSPP) structure, providing the potential of being a multifunctional composite device in the compact on-body network. Besides, an artificial magnetic conductor(AMC) is designed underneath the SSPP structure, obtaining a low SAR value(0.113 W/kg), which ensures the safety of users. As a practical realization of this concept, a textile-based spoof plasmonic antenna was fabricated in the microwave regime and the performed experimental results show the proposed antenna has a single-beam radiation characteristic with a 70° beam scanning angle range when the frequency is 4.7–6.0 GHz with a high average realized gain of 13.15 dBi. And it still maintains a steady performance when faced with structure deformation, which proves its robustness. Wireless communication quality experiments are performed to demonstrate the proposed antenna can measure the angles of targets and realize wireless signal transmission to specific targets as the frequency varies, it may find great potential in the field of on-body IoT applications.
