Wei, Donglei;Li, Huili;Yang, Chuanqing;Fu, Jianmin;Chen, Hou;Bai, Liangjiu;Wang, Wenxiang;Yang, Huawei;Yang, Lixia;Liang, Ying research published 《 Visible light-driven acridone catalysis for atom transfer radical polymerization》, the research content is summarized as follows. Acridone as a new kind of visible light photocatalyst has been developed to catalyze metal free atom transfer radical polymerization (ATRP). The photocatalyst possess low excited state potential as can undergo an oxidative quenching pathway to initiate ATRP of vinyl monomers. Kinetic study and light on/off reaction demonstrate the “living”/controlled nature of the polymerization by light. Block copolymers can be achieved by using PMMA as macroinitiator to reinitiate polymerization of other vinyl monomers, which shows highly preserved Br chain-end functionality in the synthesized polymers. Moreover, the polymerization can be conducted under air atm. as most photocatalysts need anaerobic condition, which may give inspiration of further application of this kind of photocatalyst.

Carboxyl methyltransferase (CMT) enzymes catalyze the biomethylation of carboxylic acids under aqueous conditions and have potential for use in synthetic enzyme cascades. Herein we report that the enzyme FtpM from Aspergillus fumigatus can methylate a broad range of aromatic mono- and dicarboxylic acids in good to excellent conversions. The enzyme shows high regioselectivity on its natural substrate fumaryl-L-tyrosine, trans, trans-muconic acid and a number of the dicarboxylic acids tested. Dicarboxylic acids are generally better substrates than monocarboxylic acids, although some substituents are able to compensate for the absence of a second acid group. For dicarboxylic acids, the second methylation shows strong pH dependency with an optimum at pH 5.5-6. Potential for application in industrial biotechnol. was demonstrated in a cascade for the production of a bioplastics precursor (FDME) from bioderived 5-hydroxymethylfurfural (HMF).

Interfacial adhesion influences mech. strength, structural integrity, and overall performance for adhesively bonded structures and composite materials. In this work, we investigate the effect of resin formulation chem. on wetting behavior and interfacial adhesion with a glass substrate. Thermosetting elastomer resin and cured network properties, including viscosity, surface tension, glass transition temperature, and mol. weight between crosslinks, were also characterized, and the relative importance of these properties on adhesive strength was evaluated. Resin wettability was found to be the factor most predictive of adhesive strength between thermosetting elastomers and glass surfaces, with increasing wettability (decreasing resin contact angle) correlated with increasing interfacial fracture energy. This finding provides a convenient and fast method to screen polymer networks and enables informed tailoring of interfacial fracture energy.

When the reaction of Zn nitrate with 4′,4”’,4””’,4”””’-(ethene-1,1,2,2-tetrayl)tetrakis[(1,1′-biphenyl-3-carboxylic acid)] (H₄tmpe) in DMF under hydrothermal condition was performed in air or CO₂ (CO₂), [Zn₄(tmpe)₂(H₂O)₂(μ₂-CO₂)]·8DMF·18H₂O (1) crystallizes out. However, if it is in dioxygen, Ar, or CO, [Zn₂(tmpe)(DMF)]·2DMF·8H₂O (2) is the product.

CO₂ fixation in a μ₂-η²_O,O bridging mode is observed in 1, which is rarely characterized structurally and was confirmed using IR and gas chromatog. anal. The stability of 1 is further verified by d. functional theory calculations, which found an energy min. with a Zn-O=C angle of 180°. Both compounds display strong emission around 490 nm and excited-state lifetimes around 2.4 ns. Two coordination polymers combining tetraphenylethylene derivatives and Zn ions were synthesized. Complex 1 is the 2nd example that contains the linear CO₂ μ₂-η²_O,O-bridged paddlewheel node. D. functional theory calculations indicate that the energy is minimized when the Zn-O-C angle is 180°. The authors’ studies indicate that the source of fixed CO₂ in 1 originates from air.

Wang, Shuyuan;Xu, Yue;Zhao, Yan;Zhang, Shun;Li, Min;Li, Xiaowei;He, Jinzhao;Zhou, Hong;Ge, Zemei;Li, Runtao;Yang, Baoxue research published 《 N-(4-acetamidophenyl)-5-acetylfuran-2-carboxamide as a novel orally available diuretic that targets urea transporters with improved PD and PK properties》, the research content is summarized as follows. Urea transporters (UTs) have been identified as new targets for diuretics. Functional deletion of UTs led to urea-selective urinary concentrating defects with relative salt sparing. In our previous study, a UT inhibitor with a diarylamide scaffold, which is denoted as I, was demonstrated as the first orally available UT inhibitor. However, the oral bioavailability of I was only 4.38%, which obstructed its clin. application. In this work, by replacing the nitro group of I with an acetyl group, II was obtained. Compared with I, II showed a 10 times stronger inhibitory effect on UT-B (0.14μM vs. 1.41μM in rats, and 0.48μM vs. 5.82μM in mice) and a much higher inhibition rate on UT-A1. Moreover, the metabolic stability both in vitro and in vivo and the drug-like properties (permeability and solubility) of II were obviously improved compared with those of I. Moreover, the bioavailability of II was 15.18%, which was 3 times higher than that of I, thereby resulting in significant enhancement of the diuretic activities in rats and mice. II showed excellent potential for development as a promising clin. diuretic candidate for targeting UTs to treat diseases that require long-term usage of diuretics, such as hyponatremia.

Wang, Rui;Zhang, Houyu;Jiang, Min;Wang, Zhipeng;Zhou, Guangyuan research published 《 Dynamics-Driven Controlled Polymerization to Synthesize Fully Renewable Poly(ester-ether)s》, the research content is summarized as follows. Producing aromatic poly(ester-ether)s from completely renewable feedstocks is almost inaccessible via existing ring-opening polymerization or melt polycondensation methods. Herein, we report a practical strategy to synthesize fully bio-based poly(ester-ether)s in a one-pot/two-component manner via industrial melt polycondensation. The polymerization process was controlled by applying Sc(OTf)₃ as a catalyst and bio-based 2,5-furandicarboxylic acid and ethylene glycol as the substrate template to afford poly(ester-ether)s with a controlled oligoethylene glycol segment in the range from 10 to 92%. Studying the mechanism and model kinetics of Sc(OTf)₃-catalyzed etherification reactions provided complete insights into the formation process and impetus of poly(ester-ether)s, validating that a “butterfly effect” occurred in the reaction process. In contrast to flexible conventional polyethers, computational studies revealed that the unique rigidity of the etherification moiety leads to superior thermal and mech. properties of poly(ester-ether)s. This synthetic protocol demonstrates applicability and versatility, exemplified by using various bio-based diacids/diesters to synthesize a series of poly(ester-ether)s. We envisage that this work will improve the privileged position that renewable poly(ester-ether)s hold as functional materials and broaden their applicability in diverse fields.
