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.

Pramod Charpe, Vaibhav;Gupta, Mahima;Chu Hwang, Kuo research published 《 Visible-Light-Induced Oxidative α-keto-Dichlorination of Arylalkynes by CuCl₂ at Room Temperature》, the research content is summarized as follows. A visible light-induced oxidative α-keto-dichlorination of terminal and internal aryl alkynes was developed to form dichloroacetophenones (DCAPs) and dichlorophenyl-acetophenones (DCPAPs), resp., by using CuCl₂ as a photoredox catalyst in the presence of air at room temperature (without using any exogenous photocatalyst). Here, photoexcited CuCl₂ underwent ligand-to-metal charge transfer to generate a Cl radical, which readily added to the alkynes to form DCAPs or DCPAPs in the presence of O₂. This α-keto-dichlorination reaction is a green and mild protocol as it produced water as the only byproduct. Moreover, the evaluation of green chem. metrics indicated that the E-factor (mass of wastes/mass of products) of the current α-keto-chlorination method is around 10.1 times lower than that of a literature-reported photochem. method. The Eco Scale value (score 55, which on a scale of 0-100 indicates an acceptable synthesis) signifies that this process is simple, highly efficient, eco-friendly, and cost-effective.

Pradhan, Tapas R.;Paudel, Mukti;Feoktistova, Taisiia;Cheong, Paul Ha-Yeon;Park, Jin Kyoon research published 《 Silaborative Assembly of Allenamides and Alkynes: Highly Regio- and Stereocontrolled Access to Bi- or Trimetallic Skipped Dienes》, the research content is summarized as follows. A highly stereo- and regiocontrolled multicomponent approach to skipped 1,4-dienes decorated with one boryl and two silyl functionalities, XNR¹CH:C(Bpin)CH₂CR²:CHSiMe₂Ph (X = sulfonyl, acyl; R¹ = benzyl, alkyl; R² = silyl, aryl, alkyl, carboxy) is described, comprising three-component reaction of allenamides XNR¹CH:C:CH₂ with alkynes R²CCH and silylborane Me₂PhSiBpin, catalyzed by Pd₂(dba)₃. This Pd-catalyzed atom-economical union of allenamides, alkynes, and Me₂PhSiBpin (or Et₃SiBpin) proceeds without the use of phosphine ligands, instead relying on chelation through the internal amide group of the allenamide sulfonyl. A variety of alkynes, including those derived from complex bioactive mols., can be efficiently coupled with allenamides and Me₂PhSiBpin in good yields and with excellent selectivity. The synthetic potential was demonstrated through multiple valuable chemoselective transformations, establishing new disconnections for functionalized dienes. D. functional theory calculations revealed that the reaction first proceeded through borylation of the allenamide, followed by silylation of the alkyne and then reductive elimination, which convergently assemble the skipped 1,4-diene.
