Wang, Sheng;Gai, Yongkang;Sun, Lingyi;Lan, Xiaoli;Zeng, Dexing;Xiang, Guangya;Ma, Xiang research published 《 Synthesis and evaluation of novel 1,4,7-triazacyclononane derivatives as Cu²⁺ and Ga³⁺ chelators》, the research content is summarized as follows. Advances in chelator design are the cornerstone for the development of metals like copper and gallium based biomedical agents and radiopharmaceuticals. To develop optimal chelating ligands, the authors explored the synthesis and chelating properties of azaheterocycle pendant armed 1,4,7-triazacyclononane (TACN) dimethylcarboxylate derivatives and dimethylphosphonate derivatives In the complexation kinetics test, dicarboxylate pendant armed TACN derivatives 2,2′-(7-((1H-imidazol-2-yl)methyl)-1,4,7-triazonane-1,4-diyl)diacetic acid (NODA-Im), 2,2′-(7-((1-methyl-1H-imidazol-2-yl)methyl)-1,4,7-triazonane-1,4-diyl)diacetic acid (NODA-MeIm), and 2,2′-(7-(thiazol-2-ylmethyl)-1,4,7-triazonane-1,4-diyl)diacetic acid (NODA-Thia) exhibited fast complexation kinetics towards Cu (II) cations, which were comparable to the frequently explored ligand 1,4,7-triazacyclononane-1,4,7-triacetic acid (NOTA). And the diphosphonate pendant armed TACN derivative ((7-(thiazol-2-ylmethyl)-1,4,7-triazonane-1,4-diyl)bis(methylene))bis(phosphonic acid) (NODP-Thia) bound with Ga (III) cations at a much faster rate than NOTA. D. functional theory studies confirmed that the better complexation kinetics and metal chelating efficiency of NODA-Im, NODA-MeIm, NODA-Thia, and NODP-Thia could be ascribed to the lower Gibbs energies of corresponding chelator-metal complexes than NOTA-metal complexes. The kinetic inertness of the Cu (II) complex with NODA-Im, NODA-MeIm, and NODA-Thia was also demonstrated by cyclic voltammetry studies. Subsequently radiolabeling experiment demonstrated that these metal chelators could efficiently labeled with ⁶⁴Cu or ⁶⁸Ga in good radiochem. purities. These preliminary findings support NODA-Im, NODA-MeIm, NODA-Thia, and NODP-Thia as promising leading chelating agents for the development of bifunctional Cu²⁺ and Ga³⁺ chelators in biomedical applications.

Wang, Minghui;Lin, Yuxin;Lu, Jianyang;Sun, Zhaowei;Deng, Ying;Wang, Lei;Yi, Yongxiang;Li, Jinlong;Yang, Jie;Li, Genxi research published 《 Visual naked-eye detection of SARS-CoV-2 RNA based on covalent organic framework capsules》, the research content is summarized as follows. The ongoing outbreak of coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has highlighted that new diagnosis technologies are crucial for controlling the spread of the disease. Especially in the resources-limit region, conveniently operated methods such as “naked-eye” detection are urgently required that no instrument is needed. Herein, we have designed a novel and facile strategy to fabricate covalent organic framework (COF) capsules, which can be utilized to establish a new colorimetric assay for naked-eye detection of SARS-CoV-2 RNA. Specifically, we employ the digestible ZIF-90 as the sacrificial template to prepare the hollow COF capsules for horseradish peroxidase (HRP) encapsulation. The fabricated COF capsules can provide an appropriate microenvironment for the enzyme mols., which may improve the conformational freedom of enzymes, enhance the mass transfer, and endow the enzyme with high environmental resistance. With such design, the proposed assay exhibits outstanding anal. performance for the detection of SARS-CoV-2 RNA in the linear range from 5 pM to 50 nM with a detection limit of 0.28 pM which can go parallel to qTR-PCR anal. Our method also possesses excellent selectivity and reproducibility. Moreover, this method can also be served to analyze the clin. samples, and can successfully differentiate COVID-19 patients from healthy people, suggesting the promising potential in clin. diagnosis.

Wang, Jian Hua;Liu, Yao Ming;Chao, Jian Bin;Wang, Hui;Wang, Yu;Shuang, ShaoMin research published 《 A simple but efficient fluorescent sensor for ratiometric sensing of Cd²⁺ and bio-imaging studies》, the research content is summarized as follows. A very simple schiff base fluorescent probe (NIS) was facilely prepared via a one-step, one-pot condensation reaction between 2, 3-naphthalenediamine and imidazole-2-carboxaldehyde. Among common biol. relevant metal ions, NIS can selectively recognize Cd²⁺ via ratiometric fluorescence signal. The chelation of NIS with the Cd²⁺ ions resulted in a fluorescence enhancement together with a blue shift (∼74 nm) in the emission maxima, presumably due to the combined effects of ICT (internal charge transfer) and CHEF (chelation-enhanced fluorescence). The binding stoichiometry of NIS to Cd²⁺ is 1:1 and the fluorescence intensity ratio (F₃₉₈/F₄₇₂) changes allow a ratiometric detection of Cd²⁺ with the detection limit of 3.87 × 10^-7 M. Under fluorescence confocal microscope and via two emission channels, the probe is capable to detect Cd²⁺ ions in Human liver cancer cells (SMMC-7721), zebrafish and live tissues of Arabidopsis thaliana, demonstrating its applicability for detecting Cd²⁺ ions in different biol. context with low toxicity.

Wang, Jian Hua;Liu, Yao Ming;Chao, Jian Bin;Wang, Yu;Wang, Hui;Shuang, Shao Min research published 《 A phenazine-imidazole based ratiometric fluorescent probe for Cd²⁺ ions and its application in in vivo imaging》, the research content is summarized as follows. A new phenazine-imidazole based Schiff base (PIS) fluorescent probe has been developed for the ratiometric detection of Cd²⁺ ions in aqueous media at physiol. pH. PIS upon binding with Cd²⁺ ions shows red shifted fluorescence and thereby, permits ratiometric detection of Cd(II) ions. A detection limit down to 2.10 x 10^-8 M was determined for Cd²⁺ quantitation. Also, the accompanying apparent fluorescence color change (from yellow to orange red) is noticeable to the naked eye under a UV-lamp. The sensing mechanism could be attributed to the 1 : 1 PIS-Cd complexation, followed by extension of the conjugation due to better planarity and modulation of the charge transfer efficiency in the probe. This was complemented by solvatochromism and d. functional theory calculations Furthermore, PIS was used to detect Cd²⁺ in Oxya chinensis cells, zebrafish larvae and live tissues of Arabidopsis thaliana under a fluorescence microscope, showing great potential in analyzing living biosystems.

Methylene blue (MB) is widely used as a photosensitizer in photodynamic therapy applications. However, it is easily reduced by reductases in biol. environments, which hampers its further applications. Here, we developed a one-pot method to synthesize MB-encapsulated and poly(vinylpyrrolidone) (PVP)-modified zeolitic imidazolate framework-90 (ZIF-90) nanoparticles (MB@ZIF-90/PVP NPs). The NPs show intact crystalline structure with improved colloidal dispersity and stability both in water and in the medium for cell culture. The size of the enzymes is much larger than the pore size of ZIF-90; thus, the access of reductive enzymes to encapsulated MB is prohibited, resulting in the protection of MB′s photodynamic activity. Furthermore, cell experiments confirm that MB@ZIF-90/PVP NPs have lower dark cytotoxity than equivalent free MB but can efficiently induce photodynamic damage to tumor cells even in the presence of reductive enzymes upon light irradiation

Wang, Huan;Wong, Alison;Lewis, Luke C.;Nemeth, Genevieve R.;Jordan, Veronica Clavijo;Bacon, Jeffrey W.;Caravan, Peter;Shafaat, Hannah S.;Gale, Eric M. research published 《 Rational Ligand Design Enables pH Control over Aqueous Iron Magnetostructural Dynamics and Relaxometric Properties》, the research content is summarized as follows. Complexes of Fe³⁺ engage in rich aqueous solution speciation chem. in which discrete mols. can react with solvent water to form multinuclear μ-oxo and μ-hydroxide bridged species. Here we demonstrate how pH- and concentration-dependent equilibration between monomeric and μ-oxo-bridged dimeric Fe³⁺ complexes can be controlled through judicious ligand design. We purposed this chem. to develop a first-in-class Fe³⁺-based MR imaging probe, Fe-PyCy2AI, that undergoes relaxivity change via pH-mediated control of monomer vs dimer speciation. The monomeric complex exists in a S = 5/2 configuration capable of inducing efficient T₁-relaxation, whereas the antiferromagnetically coupled dimeric complex is a much weaker relaxation agent. The mechanisms underpinning the pH dependence on relaxivity were interrogated by using a combination of pH potentiometry, ¹H and ¹⁷O relaxometry, electronic absorption spectroscopy, bulk magnetic susceptibility, ESR spectroscopy, and X-ray crystallog. measurements. Taken together, the data demonstrate that PyCy2AI forms a ternary complex with high-spin Fe³⁺ and a rapidly exchanging water coligand, [Fe(PyCy2AI)(H₂O)]⁺ (ML), which can deprotonate to form the high-spin complex [Fe(PyCy2AI)(OH)] (ML(OH)). Under titration conditions of 7 mM Fe complex, water coligand deprotonation occurs with an apparent pK_a 6.46. Complex ML(OH) dimerizes to form the antiferromagnetically coupled dimeric complex [(Fe(PyCy2AI))₂O] ((ML)₂O) with an association constant (K_a) of 5.3 ± 2.2 mM^-1. The relaxivity of the monomeric complexes are between 7- and 18-fold greater than the antiferromagnetically coupled dimer at applied field strengths ranging between 1.4 and 11.7 T. ML(OH) and (ML)₂O interconvert rapidly within the pH 6.0-7.4 range that is relevant to human pathophysiol., resulting in substantial observed relaxivity change. Controlling Fe³⁺ μ-oxo bridging interactions through rational ligand design and in response to local chem. environment offers a robust mechanism for biochem. responsive MR signal modulation. We demonstrate how pH- and concentration-dependent equilibration between monomeric and μ-oxo-bridged dimeric Fe³⁺ complexes can be controlled through judicious ligand design.

The exploitation of salt-resistant photothermal materials is of great importance for practical solar desalination. Herein, we report, for the first time, the synthesis of monolithic porous ionic polymers (PIPs) coated with polypyrrole (PPy) as self-desalting photothermal materials for efficient solar steam generation. Based on their good thermal insulation, the desired mesopores, and the extremely high light absorption (98%), the PPy-coated PIPs exhibit a high evaporation efficiency of 89% under 1 sun irradiation and superior durability in terms of evaporation efficiency in high-salinity (30 wt %) brine. Quite different from the existing salt-resistant photothermal materials by the artificial creation of aligned channels or Janus wettability, interestingly, the self-desalting of our materials depends on their intrinsically porous ionic framework, which could serve as “ions barrier” to shield the cations of saline solution These findings may provide an opportunity for future design and fabrication of self-desalting photothermal materials by only one-pot synthesis without a further complicated process.
