Rao, Nian;Le, Yi;Li, Dan;Zhang, Yan;Wang, Qin;Liu, Li;Yan, Longjia research published 《 A new phenothiazine-based fluorescent probe for detection of hydrazine with naked-eye color change properties》, the research content is summarized as follows. A new fluorescent probe (PAC) based on phenothiazine was designed and synthesized for the detection of hydrazine (N₂H₄), which uses Me cyanoacetate as the recognition group and phenothiazine as the fluorescent chromophore. The Stoke shift of probe PAC at the presence of hydrazine reached to 120 nm and the detection limit of probe PAC performed as 6.7 ppb. PAC had AIE properties and provided with the functions of naked-eye recognition. The DFT and TD-DFT calculations exhibited that the probes of PAC performed good responses to hydrazine. In addition, cell imaging showed that the probe PAC effectively recognized the hydrazine in HepG2 cells and stained the cells green.

Quintavalla, Arianna;Veronesi, Ruben;Speziali, Laura;Martinelli, Ada;Zaccheroni, Nelsi;Mummolo, Liviana;Lombardo, Marco research published 《 Allenamides Playing Domino: A Redox-Neutral Photocatalytic Synthesis of Functionalized 2-Aminofurans》, the research content is summarized as follows. A photoredox catalytic synthesis of functionalized 2-aminofurans I [R = OPh, 2-oxooxazolidin-3-yl, indol-1-yl, etc.; R¹ = Me, Ph, 2-thienyl, etc.; R² = H, Me, CO₂Et, etc.] was proposed starting from α-halo carbonyl substrates and N-allenamides. The use of visible light as green energy source, redox-neutral nature of the transformation allowing to avoid additives and strong oxidants, mild reaction conditions and the functional groups tolerance, low photocatalyst loading and the absence of excess reagents, one-pot formation of three new bonds in a domino sequence, these features of this protocol made it particularly efficient and sustainable. According to mechanistic hypothesis, the transformation was configured as a double radical-polar crossover reaction, in which the photocatalyst was excited, oxidized and reduced twice for each mol. of 2-aminofuran produced. The novelty of the designed synthetic approach also lied in the use of N-allenamides as substrates, which, after the addition of the first electrophilic radical, preserve a further reactive π-system, made possible the addition of a second α-keto radical and enabling the installation of a keto functionality at a remote position. The good yields, broad scope and possibility to further synthetically elaborate the obtained furans made this protocol particularly promising for the construction of useful products.

Qiu, Boya;Alberto, Monica;Mohsenpour, Sajjad;Foster, Andrew B.;Ding, Shengzhe;Guo, Zunmin;Xu, Shaojun;Holmes, Stuart M.;Budd, Peter M.;Fan, Xiaolei;Gorgojo, Patricia research published 《 Thin film nanocomposite membranes of PIM-1 and graphene oxide/ZIF-8 nanohybrids for organophilic pervaporation》, the research content is summarized as follows. In this work, thin film nanocomposite (TFN) membranes of super-glassy polymer PIM-1 containing zeolitic imidazolate framework-8 (ZIF-8)/graphene oxide (GO) composites (ZG) have been prepared by dip-coating onto water pre-impregnated polyvinylidene fluoride (PVDF) substrates. Higher flux and improved separation factors as compared to bare PIM-1 thin film composite (TFC) membranes have been achieved in organophilic pervaporation; for an aqueous feed solution with 5 wt% of butanol at 65°C, a total permeate flux of 7.9 ± 0.69 kg m-²h^-1 and a separation factor (β_BtOH/H2O) of 29.9 ± 1.99 have been obtained with a TFC membrane containing 0.5 wt% of ZG filler. The pervaporation separation index (PSI) of this membrane (228 kg m^-2h^-1) is amongst the highest values reported in the literature. This excellent performance is attributed to the formation of a defect-free PIM-1 active layer (<1μm) and the hydrophobic nature of the ZG fillers.

Qin, Yinhui;Sun, Min;Zhang, Na;Yang, Yan;Ma, Peizhi research published 《 Synthesis and biological evaluation of antibacterial activity of novel clarithromycin derivatives incorporating 1,2,3-triazole moieties at the 4′′- and 11-OH positions》, the research content is summarized as follows. Bacterial infection is still one of the diseases that threaten human health, and bacterial drug resistance is widespread worldwide. As a result, their eradication now largely relies on antibacterial drug discovery. Here, we reveal a novel approach to the development of 14-membered macrolide antibiotics by describing the design, synthesis, and evaluation of novel clarithromycin derivatives incorporating 1,2,3-triazole moieties at the 4′′- and 11-OH positions. Using chem. synthesis, I [R¹ = H, 4-Me, 4-Et, etc.,], II [R² = 4-Et, 4-Pr, 4-tert-Bu, etc.,] were prepared, and their antibacterial properties were profiled. We found that compounds I = [R¹ = 4-Bu, 4-n-pentyl, 4-n-hexyl and 4-Ph, 4-n-pentoxy, 4-F, 4-Cl, 4-Br, 3,5-bis(trifluoromethyl)] and II = [R² = 4-n-pentyl] were as potent as azithromycin against Enterococcus faecalis ATCC29212. Furthermore, compounds I = [R¹ = 4-Et, 4-Pr, 4-Cl and 4-Br] showed slightly improved antibacterial activity (2-fold) against Acinetobacter baumannii ATCC19606 when compared with azithromycin and clarithromycin. In addition, compounds I = [R¹ = 4-Bu, 4-n-pentyl, 4-Ph, 4-n-pentoxy and 3,5-bis(trifluoromethyl)] exhibited excellent antibacterial activity against Staphylococcus aureus ATCC43300, Staphylococcus aureus PR, and Streptococcus pneumoniae ER-2. These compounds were generally 64- to 128-fold more active than azithromycin, and 32- to 128-fold more active than clarithromycin. The results of mol. docking indicated that compound 8f may bind to the nucleotide residue A752 through hydrogen-bonding, hydrophobic, electrostatic, or π-π stacking interactions. The predicted ClogP data suggested that higher values of ClogP (>6.65) enhanced the antibacterial activity of compounds such as I = [R¹ = 4-Bu, 4-n-pentyl, 4-Ph, 4-n-pentoxy and 3,5-bis(trifluoromethyl)]. The determination of the min. bactericidal concentration showed that most of the tested compounds were bacteriostatic agents. From this study of bactericidal kinetics, we can conclude that compound 8f had a concentration- and time-dependent effect on the proliferation of Staphylococcus aureus ATCC43300. Finally, the results of the cytotoxicity assay showed that compound I = [R¹ = 4-n-pentyl] exhibited no toxicity at the effective antibacterial concentration

Pu, Yunchuan;Yang, Ziqi;Wee, Vanessa;Wu, Zhongjie;Jiang, Zhongyi;Zhao, Dan research published 《 Amino-functionalized NUS-8 nanosheets as fillers in PIM-1 mixed matrix membranes for CO₂ separations》, the research content is summarized as follows. Membrane-based separation technologies are promising for various applications such as carbon capture and storage (CCS). Herein, we report the preparation and performance of mixed matrix membranes (MMMs) for carbon dioxide (CO₂) separation The MMMs comprise amino-functionalized metal-organic framework (MOF) nanosheets (NUS-8-NH₂) dispersed in the polymer of intrinsic microporosity 1 (PIM-1). Specifically, the MOF nanosheets were synthesized through a bottom-up method and introduced into the PIM-1 matrix to fabricate NUS-8-NH₂/PIM-1 MMMs. The uniformly dispersed MOF nanosheets could afford addnl. fast transport pathways through intra-flake pores and inter-flake nano-channels. Moreover, the amino groups could enhance CO₂ transport within NUS-8-NH₂/PIM-1 MMMs. In addition, hydrogen bonding between the NUS-8-NH₂ filler and PIM-1 matrix improved interfacial compatibility. Therefore, the as-prepared MMMs could achieve a high filler loading of 15 wt% without sacrificing separation performance. Compared with the pure PIM-1 membrane, the MMM with 10 wt% NUS-8-NH₂ showed CO₂ permeability of ∼14000 Barrer and a CO₂/N₂ selectivity of ∼30, surpassing the 2008 Robeson’s upper bound.
