Isomeric triazines exhibit unique profiles of bioorthogonal reactivity. [PDF]

open access: yesChemical Science, 2019
Expanding the scope of bioorthogonal reactivity requires access to new and mutually compatible reagents. We report here that 1,2,4-triazines can be tuned to exhibit unique reaction profiles with biocompatible strained alkenes and alkynes.

Influence of triazines and lipopolysaccharide coexposure on inflammatory response and histopathological changes in the testis and liver of BalB/c mice [PDF]

open access: yesHeliyon
Background: Triazines are environmental active chemicals that have been reported to alter the inflammatory status of the gonads. We tested the anti-inflammatory effect of the triazines (atrazine; ATZ, simazine; SMZ and cyanazine; CYZ) on the testis and ...

A Universal Method for the Synthesis of new Heterocyclic Systems: Pyrimido[2,1‐f][1,2,4]triazines [PDF]

open access: yesChemistryOpen
The synthesis of pyrimido[2,1‐f][1,2,4]triazines was performed in four steps. Compounds obtained by acylation of the starting amino esters of thieno[2,3‐b]pyridines were reacted with various amines.

Sorption of four s-triazine herbicides on natural zeolite and clay mineral materials with microporosity

open access: yesFundamental Research, 2021
Sorption is an important process that controls the fate and transport of herbicides in the soil and aquifer environment. However, sorption of these pollutants on natural microporous mineral materials has received little attention. This study investigated
