Design and Synthesis of Triazole‐Based p‐tert‐Butylcalix[4]Arene Conjugates and Evaluation of Their Antimicrobial, Antibiofilm, and Anti‐Quorum‐Sensing Activities

open access: yesBiotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Macrocyclic calix[n]arenes have many applications, with diverse structures that can easily be functionalized either on upper or lower rims, mostly to impart solubility and improve biological activities. In this study, triazole‐based p‐tert‐butylcalix[4]arene conjugates (AT10a and AT10b) and their p‐tert‐butylphenol analogs (AT10b and AT11b ...

Derivatizing immobilization methods for TEMPO radicals in metal–organic frameworks: Toward efficient aerobic oxidation and sequential reactions

open access: yesBulletin of the Korean Chemical Society, EarlyView.
Covalent attachment of TEMPO radicals to Zr‐based metal–organic frameworks (MOFs) was achieved by diversifying linker structures, enabling efficient aerobic oxidation of secondary alcohols. The modified MOFs facilitated sequential reactions, including isoxazole synthesis via aerobic oxidation and cycloaddition, demonstrating their versatility and ...

Evaluation of Polar Substituted Schiff Bases and 1,2,3‐Triazole Hybrids as Anticancer Agents

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT Polar substituted Schiff bases and 1,2,3‐triazole hybrids (2–6) were successfully synthesized by Schiff base condensation reaction between the previously synthesized triazole 1 and series of polar substituted amines. The chemical structures of the hybrids were confirmed using spectroscopies (NMR and FTIR), CHN elemental analysis and single ...

Novel Approaches To Design Glycan‐Based Antibacterial Inhibitors

open access: yesEuropean Journal of Organic Chemistry, Volume 26, Issue 1, January 2, 2023., 2023
Sweet and sticky: This review describes recent advances in the synthesis and application of homo‐and heterovalent glycan‐scaffolds as potential candidates for efficient bacteria lectin inhibition. To study and address the many complex molecular mechanisms involved in multivalent lectin binding events, novel glycoconjugate designs and fine‐tunable ...

Development of Multipurpose Supported Asymmetric Salen Catalysts by Cu(0)‐Mediated Reversible Deactivation Radical Copolymerization

open access: yesChemCatChem, EarlyView.
The challenge of recycling heterogeneous catalysts and reusing them in different reactions was addressed. To this end, salen complexes were anchored on methacrylate insoluble polymers obtained using the Cu(0)‐mediated RDRP method. Their reactivity and recyclability were analyzed in asymmetric ring opening and dynamic kinetic resolution of epoxides ...
