Age-dependance of pteridines in the malaria vector, Anopheles stephensi
Pteridines, 2017 Determining the accurate age of malaria vectors is crucial to measure the risk of malaria transmission. A group of fluorescent chemicals derived from a pyrimidine-pyrazine ring structure known as pteridines from the head, thorax and whole body of adult ...

Prospects for the use of sulfur-containing pteridines in toxic liver damage
Regulatory Mechanisms in BiosystemsThe presented material describes the results of the purposeful search for the novel hepatoprotective agents among synthetic sulfur-containing pteridines. The studied compounds were obtained using previously described synthetic procedures.

Folate, neopterin and kynurenine pathway in patients with statin therapy
Pteridines, 2016 Statins, widely used antihyperlipidemic drugs, also have immunomodulatory properties independent from their lipid lowering effect. Even with slight modulations in the immune system, pteridine levels can display changes.

Pteridines CII Synthesis and Characterization of Dimeric Lumazines
Pteridines, 1994 Reduction of 1.3-dimethyllumazine (1) by zinc dust in Ac2O/AcOH leads to the formation of 6-7 connected bis-Iumazinyl derivatives. Depending on the reaction conditions either 7 -(5-acetyl-5,6, 7,8-tetrahydro-1.3-dimethyllumazin- 6-yl)-l, 3 ...

Pteridines XCVIII. Synthesis and Properties of 1-Methylpterins
Pteridines, 1993 A series of 1-methyl-pterin derivatives (6-13) have been synthesized by condensation and methylation reactions. The compounds have been characterized by elemental analyses, pKa deterimations and UV spectra.

Eye can see clearly now: Identifying the locus associated with a white-eye mutation in honey bees (Apis mellifera). [PDF]
Insect Mol BiolWe performed a community science investigation with the beekeepers nationwide to find phenotypic mutants. Alongside a beekeeper in Kentucky, we performed a GWAS to identify a region associated with a white‐eye phenotype. We identified an eight bp region in a non‐coding RNA strongly associated with white eyes.
