Chitosan-Based Schiff Bases (CSBs) and Their Metal Complexes: Promising Antimicrobial Agents

Molecules, Год журнала: 2025, Номер 30(2), С. 207 - 207

Опубликована: Янв. 7, 2025

The scientific interest in the chemical modification of chitosan to increase its solubility and application has led conjugation with Schiff bases, which are interesting scaffolds endowed diverse biological properties. resultant chitosan-based bases (CSBs) widely studied literature due myriad activities exerted, both catalytic biological, including anticancer, anti-inflammatory, antioxidant, especially antimicrobial ones. Antimicrobial resistance (AMR) is one major public health challenges twenty-first century because it represents a threat prevention treatment growing number bacterial, parasitic, viral, fungal infections that no longer treatable available drugs. Thus, this review, we present brief outline CSBs as well their complexes metals, particular focus on recent regarding effect these captivating derivatives.

Characterization of novel cold-active chitin deacetylase for green production of bioactive chitosan

AMB Express, Год журнала: 2025, Номер 15(1)

Опубликована: Янв. 4, 2025

Abstract A Novel cold-active chitin deacetylase from Shewanella psychrophila WP2 (SpsCDA) was overexpressed in Escherichia coli BL21 and employed for deacetylation of to chitosan. The produced chitosan characterized, its antifungal activity investigated against Fusarium oxysporum . purified recombinant SpsCDA appeared as a single band on SDS-PAGE at approximately 60 kDa, specific 92 U/mg. optimum temperature pH were 15 °C 8.0, respectively, the enzyme significantly enhanced presence NaCl. bioconversion by accomplished 72 h, yield 69.2%. solubility estimated be 73.4%, degree 78.1%. molecular weight 224.7 ± 8.4 kDa with crystallinity index (CrI) value 18.75. Moreover, FTIR XRD spectra revealed characteristic peaks enzymatically compared standard chitosan, indicating their structural similarity. inhibited spore germination F. minimum inhibitory concentration (MIC) 1.56 mg/mL. potential effect is attributed inhibition accompanied ultrastructural damage membranes leakage cellular components, evidenced transmission electron microscopy (TEM), accumulation reactive oxygen species (ROS) that confirmed fluorescence microscopy. This study shed light S. provides candidate green preparation
