Song, Yanqin;Ismail, Muhammad;Shan, Qi;Zhao, Jianing;Zhu, Yanping;Zhang, Leiming;Du, Yuan;Ling, Longbing research published 《 ROS-mediated liposomal dexamethasone: a new FA-targeted nanoformulation to combat rheumatoid arthritis via inhibiting iRhom2/TNF-α/BAFF pathways》, the research content is summarized as follows. Rheumatoid arthritis (RA) is an autoimmune inflammatory disorder that has seriously affected human health worldwide and its current management requires more successful therapeutic approaches. The combination of nanomedicines and pathophysiol. into one system may provide an alternative strategy for precise RA treatment. In this work, a practical ROS-mediated liposome, abbreviated as Dex@FA-ROS-Lips that comprised synthetic dimeric thioether lipids (di-S-PC) and a surface functionalized with folic acid (FA), was proposed for dexamethasone (Dex) delivery. Incorporation with thioether lipids and a FA segment significantly improved the triggered release and improved the triggered release of cytotoxic Dex as well as the active targeting of RA, altering its overall pharmacokinetics and safety profiles in vivo. As proof, the designed Dex@FA-ROS-Lips demonstrated effective internalization by LPS-activated Raw264.7 macrophages with FA receptor overexpression and released Dex at the inflammatory site due to the ROS-triggered disassembly. I.v. injection of this Dex@FA-ROS-Lips into adjuvant-induced arthritis (AIA) mice led to its incremental accumulation in inflamed joint tissues and significantly alleviated the cartilage destruction and joint swelling via suppression of proinflammatory cytokines (iRhom2, TNF-α and BAFF), as compared to the effect of com. free Dex. Importantly, the Dex@FA-ROS-Lips nanoformulation showed better hemocompatibility with less adverse effects on the body weight and immune organ index of AIA mice. The anti-inflammatory mechanism of Dex@FA-ROS-Lips was further studied and it was found that it is possibly associated with the down-regulation of iRhom2 and the activation of the TNF-α/BAFF signaling pathway. Therefore, the integration of nanomedicines and the RA microenvironment using multifunctional Dex@FA-ROS-Lips shall be a novel RA treatment modality with full clin. potential, and based on the enhanced therapeutic effect, the signaling pathway of iRhom2/TNF-α/BAFF reasonably explained the mechanism of Dex@FA-ROS-Lips in anti-RA, which suggested a mol. target for RA therapy and other inflammatory diseases.

Song, Xue;Li, Yan-Xiang;Zhou, Li;Liu, Na;Wu, Zong-Quan research published 《 Controlled Synthesis of One-Handed Helical Polymers Carrying Achiral Organoiodine Pendants for Enantioselective Synthesis of Quaternary All-Carbon Stereogenic Centers》, the research content is summarized as follows. Inspired by highly efficient and enantioselective reactions catalyzed by biomacromols., developing artificial helical polymer-based catalysts for enantioselective reactions is an interesting work. In this work, a series of one-handed helical polyisocyanides bearing aryl iodine pendants were readily produced via asym. polymerization of achiral isocyanides using chiral Pd(II)-catalysts. Despite the inexistence of any stereogenic centers, these polymers showed large optical activity owing to the one-handed helicity. Remarkably, these polymers could catalyze asym. dearomatization spirocyclization of 1-hydroxy-N-aryl-2-naphthamide derivatives and gave chiral spirooxindole products with high enantioselectivity. The enantioselectivity was contributed by the helicity of the polyisocyanide backbone; helical polyisocyanides in opposite helicity produced the enantiomeric antipode products with comparable yields and similar high enantioselectivity. Thanks to the high mol. weight, the helical polymer catalysts could be recycled 10 times with maintained activity and stereoselectivity.

Song, Sungwon;Yang, Seok Joo;Choi, Wookjin;Lee, Hansol;Sung, Woong;Park, Chaneui;Cho, Kilwon research published 《 Molecular Engineering of Organic Spacer Cations for Efficient and Stable Formamidinium Perovskite Solar Cell》, the research content is summarized as follows. Low dimensional (LD) perovskite materials generally exhibit superior chem. stability against ambient moisture and thermal stress than that of 3D perovskites. Recently, LD perovskite has been used as a passivation layer on the surface of 3D perovskite grains. Although various LD perovskites have been developed focusing on their hydrophobicity, the impact of crystal structure of LD perovskite on the photovoltaic performance of perovskite solar cell (PSC) is still uncertain. In this work, the effects of the structural characteristics of LD perovskites on the crystal formation of formamidinium lead triiodide (α-FAPbI3) and on the optoelec. properties of PSCs are elucidated. The phase-transformation kinetics of formamidinium lead triiodide mixed with LD perovskites is studied using the Johnson-Mehl-Avrami-Kolmogorov model. It is found that the arrangement of PbI6 octahedra in the LD perovskite changes the rate of α-formamidinium lead triiodide formation. Facilitated nucleation of α-formamidinium lead triiodide at the LD/formamidinium lead triiodide interface results in minimal structural disorder and prolonged charge-carrier lifetimes. As a result, the PSC with the optimized LD perovskite structure exhibits a power conversion efficiency of 21.25% from a reverse current-voltage scan, and stabilized efficiency of 19.95% with excellent ambient stability without being encapsulated.

A synthetic method to prepare tetrahydroquinoline-4-carboxylic acid esters has been developed through the transition-metal-catalyzed intramol. aromatic C-H functionalization of α-diazoesters. Both [{Pd(IMes)(NQ)}₂] (IMes = 1,3-dimesitylimidazol-2-ylidene, NQ = 1,4-naphthoquinone) and the first-generation Grubbs catalyst proved effective for this purpose. The ruthenium catalyst was found to be the most versatile, although in a few cases the palladium complex afforded better yields or selectivities. According to DFT calculations, Pd⁰– and Ru^II-catalyzed sp²-C_Ar-H functionalization proceeds through different reaction mechanisms. Thus, the Pd⁰-catalyzed reaction involves a Pd-mediated 1,6-H migration from the sp²-C_Ar-H bond to the carbene carbon atom, followed by a reductive elimination process. In contrast, electrophilic addition of the ruthenacarbene intermediate to the aromatic ring and subsequent 1,2-proton migration are operative in the Grubbs catalyst promoted reaction.
