Pterins as Sensors of Response to the Application of Fe3+-Dextran in Piglets

Sensors, 2010
The aim of the presented study was to assess the effect of a single administration of Fe3+-dextran on immune cell counts and pterin biomolecule production as novel sensors of the piglets' immune system activation, and to determine concentrations of ...

Identification of Novel Potential Inhibitors of Pteridine Reductase 1 in Trypanosoma brucei via Computational Structure-Based Approaches and in Vitro Inhibition Assays

Molecules, 2019
Pteridine reductase 1 (PTR1) is a trypanosomatid multifunctional enzyme that provides a mechanism for escape of dihydrofolate reductase (DHFR) inhibition. This is because PTR1 can reduce pterins and folates.

Dual Antimicrobial–Antioxidant Postbiotics From Lactiplantibacillus plantarum for Clean‐Label Meat Preservation

eFood, Volume 7, Issue 2, April 2026.
The postbiotics, which possess both antimicrobial and antioxidant activities, are derived from Lactiplantibacillus plantarum strains, revealing the presence of bioactive compounds. Functional assays showed strong antioxidant activity and strain‐specific antimicrobial effects. When applied to pork, these postbiotics significantly reduced microbial loads,

Comprehensive Analysis of Structure Activity Relationships in Quinoxaline Derivatives Covering Antimicrobial Applications

ChemistrySelect, Volume 11, Issue 14, 13 April 2026.
ABSTRACT Antimicrobial resistance (AMR) has emerged as one of the most critical global health challenges, undermining the clinical efficacy of existing antibiotics and threatening modern therapeutic strategies. The ongoing misuse and overuse of antimicrobial agents have accelerated the evolution of resistant bacterial strains and parasites ...

The pterin molybdenum cofactors.

Journal of Biological Chemistry, 1992
crassa, demonstrated that the inactive apoprotein of nitrate reductase in extracts of the mutant could be reconstituted by the addition of denatured preparations of purified molybdoenzymes from animal, fungal, or bacterial origin. This crucial finding showed that mol- ybdoenzymes contain a dissociable entity fitting the description of a cofactor and ...

Clinical and Genetic Characteristics of Free Sialic Acid Storage Disorder

Journal of Inherited Metabolic Disease, Volume 49, Issue 2, March 2026.
ABSTRACT Free sialic acid storage disorder (FSASD) is a lysosomal storage disorder that results from biallelic pathogenic variants in the SLC17A5 gene. This gene codes for sialin, a 12‐transmembrane domain protein that exports the charged sugar N‐acetylneuraminic acid (Neu5Ac; sialic acid) out of the lysosome.
