Although Zr-based metal-organic frameworks (MOFs) exhibit robust chemical and physical stability in the presence of moisture acidic conditions, their susceptibility to nucleophilic attacks from bases poses a critical challenge overall stability. Herein, we systematically investigate UiO-66 (UiO = University Oslo) MOFs basic solutions. The impact 11 standard bases, including inorganic salts organic on these is examined. destruction framework confirmed through powder X-ray diffraction (PXRD) patterns, monitored dissolution ligands assessed using nuclear magnetic resonance (NMR) spectroscopy. Our key findings reveal direct correlation between strength concentration base MOFs. summarized data provide valuable insights that can guide practical application under offering essential information for optimal utilization various settings.

The Antimicrobial Efficacy of Copper Complexes: A Review

Antibiotics, Год журнала: 2025, Номер 14(5), С. 516 - 516

Опубликована: Май 16, 2025

The alarming increase in antimicrobial resistance has intensified the search for novel therapeutic agents capable of combating resistant microbial strains. Copper complexes have emerged as promising due to their intrinsic redox activity, ability disrupt membranes, and interactions with vital biomolecules such DNA proteins. This review critically evaluates potential copper reported between 2018 2025, emphasizing structural diversity, mechanisms action, biological performance against a wide range bacterial fungal pathogens. Key findings reveal that Schiff base complexes, amino acid derivatives, heterocyclic ligands, mixed-ligand systems exhibit potent activities, often surpassing standard antibiotics. Mechanistically, induce reactive oxygen species (ROS) generation, inhibit enzyme function, cause cleavage, compromise cell membrane integrity. Furthermore, structure-activity relationship (SAR) analyses indicate ligand type, coordination geometry, lipophilicity significantly influence efficacy. Overall, reviewed studies support development copper-based compounds viable candidates drug development. also identifies current challenges gaps knowledge, limited vivo toxicity assessments, which must be addressed advance these toward clinical application.

A decade of synthesis of N-heterocyclic derivatives via magnetically retrievable Fe₃O₄@SiO₂@Cu(II) nanocatalysts: A review (2013-present)

Synthetic Communications, Год журнала: 2023, Номер 53(18), С. 1469 - 1505

Опубликована: Июнь 28, 2023

Medicinal chemistry and synthetic organic rely primarily on C-N bonds for their structures because a variety of biologically active compounds, including natural products molecules, contain N-heterocyclic as subunits, they have been assigned privileged position in drug development due to improved solubility ability form salts, both which contribute oral absorption bio-availability. In recent years, the copper-catalyzed cross-coupling reactions progressed rapidly with inexpensive, readily available, insensitive air, low-toxicity copper catalysts. The coupling strategy has used make N-heterocycles, wide range applications investigated excellent functional group tolerance. current review explores direct bond formation cyclization approaches fabricate triazole, tetrazole, various other derivatives that are catalyzed by magnetically retrievable (II)-impregnated silica-coated iron oxide nanocatalysts.

Abstract Within the extensive array of metal‐organic frameworks (MOFs), Zr‐based MOFs stand out as particularly promising materials due to their diverse structures, exceptional stability, and intriguing properties. These are currently in early stages development, but noteworthy strides have been achieved recent years. This overview focuses on progress Zr‐MOFs since 2012, covering design, synthesis, applications various reactions such C−H activation, oxidation, C−C, C−N coupling approaches. Different Zr‐MOF structural variants explained terms secondary building units a variety organic ligands. The review highlights roles that play catalysis by highlighting uses porous carriers, molecule adsorption, separation. It is anticipated this kind concentrated would offer important direction for next studies investigating catalytic applications.
