Pai, Min-Hao;Hu, Chien-Chieh;Liou, Guey-Sheng research published 《 Enhancement of Electrochromic Switching Properties with Troger’s Base-Derived Intrinsic Microporous Polyamide Films》, the research content is summarized as follows. The formation of Troger’s Base (TB) configuration is a useful approach to synthesize polymers of intrinsic microporosity (PIM). Herein, the V-shaped TB scaffold is incorporated to prepare electrochromic (EC) polyamide with electroactive triphenylamine (TPA) moiety. The presence of intrinsic microporosity derived from inefficient packing of TB scaffolds can facilitate the counterions diffusion between electroactive species and electrolytes. Consequently, the resulting TB-based polyamide exhibits enhanced EC behaviors, such as a lower driving potential, reduced the difference of redox potentials ΔE, and shorter switching response time compared to the corresponding EC counterpart polyamide.

Pan, Jun-Lin;Xu, Chu-Ran;Zeng, Fu-Rong;Liang, Yang;Zhang, Tao;Xu, Jing;Li, Zi-Long;Li, Zi-Chen research published 《 Castor Oil-Based Bioplastics via Polyesterification: Synthesis, Characterization, and Functionalization》, the research content is summarized as follows. Synthesis and application of biobased polymers are at the forefront of polymer science. Herein, we report the synthesis, characterization, and functionalization of castor oil-based bioplastics. At first, polymer P1 was synthesized via polyesterification by using monomer 11-bromoundecanoic acid (1) to demonstrate the feasibility of this step-growth polymerization method. The success of this polycondensation technique relies on the high substitution efficiency between terminal groups, carboxylic acid, and carbon-bromide moieties under alk. conditions. Subsequently, copolymers P2-P5 with varied compositions were obtained by random copolymerization of monomers 1 and 6-bromohexanoic acid (2) in different feed ratios. Linear pos. correlation is disclosed between the crystallization (T_c) and melting (T_m) temperatures of P1-P5 and the molar fraction of 1 within these specimens. Differential scanning calorimetry (DSC) and wide-angle X-ray diffraction (WAXD) results illustrate good crystallinity of these bioplastics. Furthermore, the degradation of polymers P1-P5 is propelled by an external basic environment while hindered by their intrinsic hydrophobicity, indicating that alkalinity and composition are two essential factors to manipulate the degradation behaviors of biobased polyesters in the bulk state. Ultimately, polymerization of 1 in the presence of 1-pyrenebutyric acid (3), an end-capping agent, was carried out to yield α-pyrene functionalized polymer P7. This material is capable of serving as a practical fluorescent probe and multiwalled carbon nanotube (MWNT) dispersion stabilizer. Polyesterification reported herein represents a facile and cost-effective synthetic strategy and shows great prospects in sustainable polymer materials.

Bromodomain-containing protein 4 (BRD4) and histone deacetylases (HDAC) are both attractive epigenetic targets in cancer and other chronic diseases. Based on the integrated fragment-based drug design, synthesis, and in vitro and in vivo evaluations, a series of novel thieno[2,3-d]pyrimidine-based hydroxamic acid derivatives are discovered as selective BRD4-HDAC dual inhibitors. Compound 17c is the most potent inhibitor for BRD4 and HDAC with IC₅₀ values at nanomolar levels, as well as the expression level of c-Myc, and increases the acetylation of histone H3. Moreover, 17c presents inhibitory effects on the proliferation of colorectal carcinoma (CRC) cells via inducing autophagic cell death.

Pang, Zeyang;Li, Qizhen;Jia, Yuexiao;Yan, Weixiao;Qi, Jie;Guo, Yuan;Hu, Fupin;Zhou, Dejian;Jiang, Xingyu research published 《 Controlling the pyridinium-zwitterionic ligand ratio on atomically precise gold nanoclusters allowing for eradicating Gram-positive drug-resistant bacteria and retaining biocompatibility》, the research content is summarized as follows. Infections caused by multidrug-resistant (MDR) bacteria are an increasing global healthcare concern. In this study, we developed a dual-ligand-functionalised Au₂₅(SR₁)_x(SR₂)_18-x-type gold nanocluster and determined its antibacterial activity against MDR bacterial strains. The pyridinium ligand (SR₁) provided bactericidal potency and the zwitterionic ligand (SR₂) enhanced the stability and biocompatibility. By optimizing the ligand ratio, our gold nanocluster could effectively kill MDR Gram-pos. bacteria via multiple antibacterial actions, including inducing bacterial aggregation, disrupting bacterial membrane integrity and potential, and generating reactive oxygen species. Moreover, combining the optimized gold nanocluster with common antibiotics could significantly enhance the antibacterial activity against MDR bacteria both in in vitro and animal models of skin infections. Furthermore, the fluorescence of the gold nanocluster at the second near-IR (NIR-II) biol. window allowed for the monitoring of its biodistribution and body clearance, which confirmed that the gold nanoclusters had good renal clearance and biocompatibility. This study provides a new strategy to combat the MDR challenge using multifunctional gold nanomaterials.

Ning, Xiangxue;Tan, Guiyu;Chen, Xiaojiao;Wang, Mian;Wang, Baomin;Cui, Liwang research published 《 Development of a lateral flow dipstick for simultaneous and semi-quantitative analysis of dihydroartemisinin and piperaquine in an artemisinin combination therapy》, the research content is summarized as follows. Dihydroartemisinin (DHA) and piperaquine (PPQ) are two drugs used in an artemisinin-based combination therapy (ACT). The circulation of counterfeit antimalarial drugs demands the development of simple, point-of-care (POC) tests for monitoring drug quality. Here we aimed to design an antibody-based lateral flow dipstick assay for simultaneous quality control of DHA and PPQ. To obtain a monoclonal antibody (mAb) for PPQ, one structural unit of the sym. PPQ mol. was used to derive a carboxylic acid for linkage to a carrier protein as immunogen. Screening of hybridoma cells identified an mAb 4D112B2 that reacted with the PPQ-based immunogen. A highly-sensitive icELISA was designed based on this mAb, which showed 50% inhibition concentration of PPQ at 1.66 ng/mL and a working range of 0.35 – 7.40 ng/mL. The mAb showed 10.2, 15.9 and 30.4% cross reactivity to hydroxychloroquine sulfate, chloroquine and amodiaquine, resp. No cross reactivity was observed to lumefantrine, mefloquine artemisinin and its derivatives Using our previous DHA dipstick design, a lateral flow dipstick for simultaneous anal. of PPQ and DHA was developed. The indicator ranges for PPQ and DHA were 2 – 5μg/mL and 250 – 500 ng/mL, resp. The dipstick was used to semi-quant. analyze PPQ and DHA content in com. ACT drugs, which produced agreeable results to those determined by high-performance liquid chromatog. This combination dipstick makes it a potential POC device for quality control of the two active ingredients in a commonly used ACT.

Niu, Shengtong;Zhang, Hao;Xu, Weici;Bagdi, Prasanta Ray;Zhang, Guoxiang;Liu, Jinggong;Yang, Shuang;Fang, Xinqiang research published 《 Access to enantioenriched compounds bearing challenging tetrasubstituted stereocenters via kinetic resolution of auxiliary adjacent alcohols》, the research content is summarized as follows. Contemporary asym. catalysis faces huge challenges when prochiral substrates bear electronically and sterically unbiased substituents and when substrates show low reactivities. One of the inherent limitations of chiral catalysts and ligands is their incapability in recognizing prochiral substrates bearing similar groups. This has rendered many enantiopure substances bearing several similar substituents inaccessible. Here authors report the rationale, scope, and applications of the strategy of kinetic resolution of auxiliary adjacent alcs. (KRA*) that can be used to solve the above troubles. Using this method, a large variety of optically enriched tertiary alcs., epoxides, esters, ketones, hydroxy ketones, epoxy ketones, β-ketoesters, and tetrasubstituted methane analogs with two, three, and four spatially and electronically similar groups can be readily obtained (totally 96 examples). At the current stage, the strategy serves as the optimal solution that can complement the inability caused by direct asym. catalysis in getting chiral mols. with challenging fully substituted stereocenters.
