Development and validation of chromatographic methods to study folate derivatives produced by yeasts [PDF]

, 2007
Folate, or folic acid, is an important water soluble B vitamin that exists in many different forms. Its presence is necessary for synthesis of DNA and RNA and methylation of homocysteine to methionine.

Folate polyglutamylation is required for rice seed development [PDF]

, 2010
In plants, polyglutamylated folate forms account for a significant proportion of the total folate pool. Polyglutamylated folate forms are produced by the enzyme folylpolyglutamate synthetase (FPGS).

Neopterin as a Tool for Primate Ecoimmunology: Current Knowledge, Practical Application, and New Directions From Captivity to the Wild

American Journal of Primatology, Volume 87, Issue 10, October 2025.
Neopterin is a sensitive and specific biomarker of intracellular pathogen infection and chronic inflammation, and affected by environmental, life‐history, and sex‐contextual factors. This review offers best‐practice guidelines and practical advice on sample collection, storage, and analysis in primates when used for ecoimmunological conservation and ...

Profiling of Flavonol Derivatives for the Development of Antitrypanosomatidic Drugs [PDF]

, 2016
Flavonoids represent a potential source of new antitrypanosomatidic leads. Starting from a library of natural products, we combined target-based screening on pteridine reductase 1 with phenotypic screening on Trypanosoma brucei for hit identification ...

The Role of Neopterin and Interleukin‐6 Detection in Saliva and Plasma in Oral and Oropharyngeal Cancer Patients: A Prospective Study

Clinical and Experimental Dental Research, Volume 11, Issue 5, October 2025.
ABSTRACT Objectives The incidence of oral and oropharyngeal cancer is continually rising and affects increasingly younger patients. Consequently, many studies focus on early diagnosis using appropriate biomarkers. Neopterin and interleukin‐6 (IL‐6) are promising predictive and prognostic markers of immune response activation, both systemic and local ...

Sepiapterin reductase (Spra and Sprb) regulate carotenoid and pteridine metabolism influencing the koi carp (Cyprinus carpio L.) coloration

Aquaculture Reports
The evolution of teleost coloration is strongly linked with the fish-specific genome duplication (FSGD). Sepiapterin reductase (Spr) is commonly required in pteridine pigment synthesis and two paralogs are found in teleosts.

Chemical structure of 1-O-(L-erythro-biopterin-2'-yl)-a-glucose isolated from a cyanobacterium Synechococcus sp. PCC 7942

Pteridines, 2001
A pteridine glycoside in Synechococcus sp. PCC 7942, the structure of which had been tentatively identified as biopterin-glucoside, was isolated and characterized for its exact chemical structure by 2D-NMR spectroscopy. The determined structure is 1-0-(L-

Genomic Characterisation of Limosilactobacillus fermentum CRL2085 Unveiling Probiotic Traits for Application in Cattle Feed

Environmental Microbiology Reports, Volume 17, Issue 5, October 2025.
A comprehensive genomic and phenotypic analysis of Limosilactobacillus fermentum CRL2085 revealed key probiotic and nutritional traits supporting its safe application in cattle feed. The strain harbors genes for stress tolerance, adhesion, exopolysaccharide production, and B‐vitamin biosynthesis, and efficiently metabolizes plant‐derived carbohydrates,

The role of urinary pteridines as disease biomarkers

Pteridines, 2017
Pteridines and their derivatives function as intermediates in the metabolism of several vitamins and cofactors, and their relevance to disease has inspired new efforts to study their roles as disease biomarkers.
