In this study, the role of interaction of pi electrons on the strength of simultaneous σ-hole interactions (pnicogen, chalcogen and halogen bonds) is investigated using the quantum chemical calculations. X-ben||TAZ∙∙∙Y1,Y2,Y3 complexes (X = CN, F, Cl, Br, CH3 , OH and NH2, TAZ= s-triazine and Y1,Y2 and Y3 denotes PH2F, HSF, and ClF molecules) is introduced as a model. The results show that inte...

Chlorinated herbicides (e.g. s-triazines) and polychlorobiphenyls (PCBs) are persistent organic pollutants (POPs) that are widely distributed in the environment. s-Triazine herbicides are used in agriculture and forestry in diverse regions of the world. PCBs were produced worldwide for industrial applications, and an important amount of these compounds have been released into the environment. P...

Derivatized s-triazine (C3N3) precursors have seen significant recent use in the production of carbon nitride materials. Larger polycyclic molecular precursors, such as those containing an s-heptazine core (C6N7 or tri-s-triazine), may improve stability and order in carbon nitride products. In this Communication, we describe the synthesis and crystal structure of 2,5,8-triazido-s-heptazine (2)....

alzheimer's disease (ad) is the most prevalent neurodegenerative disorder. it is characterized by formation of amyloid plaques and neurofibrillary tangles in the brain, degeneration of the cholinergic neurons and neural cell death. this study was aimed to investigate the effect of a triazine derivative, c16h12cl2n3s, on learning in an alzheimer's rat model. animals were divided into seven group...

In this work, the degradation of 2-chloro-4,6-diamino-1,3,5-triazine in aqueous solutions by photo-Fenton process has been investigated. The preliminary results have shown that the degradation of 2-chloro-4,6-diamino-1,3,5-triazine by photo-Fenton process is more rapid and more effective than Fenton and UV/H2O2 processes. The effects of certain experimental parameters on kinetics and efficiency...

Nine monoand di-chloro-s-triazine (Procion) dyes (Table) have been tested for possible use as vital markers in rhesus monkeys (Macaca mulatta). Goland and Grand (Am J Phys Anthropol 29:201-218, 1968), Prescott, Mitchell, and Fahmy (Am J Phys Anthropol 29:219-224, 1968), and Seiton and Engel (Am J Anat 126: 373-391, 1969) have demonstrated that certain types of reactive dyes are preserved in dec...

In the present paper, chemometric analysis, ranking and selection of most suitable in silico lipophilicity parameters eight alkyl cycloalkyl s-triazine derivatives were carried out. The calculated using various computational approaches computer programs. conducted analysis is basis for further studies aimed to define, compare examine influence substituents, introduced 6-chloro-1,3,5-triazine-2,...

Herein we report a parallel solid-phase synthesis of 1,3,5-triazine based nucleoside analogues by a three-step substitution, starting from 2,4,6-trichloro-1,3,5-triazine. A library of 80 galactosyl-1,3,5-triazine compounds was prepared in high purity without extensive reaction conditions or tedious purification, suggesting the generality of this method.

Aspergillus niger van Tieghem, Aspergillus tamarii Kita, and Aspergillus flavus Link ex Fries utilized the methylthio moiety of 2,4-bis(isopropylamino) -6-methyl-mercapto-s-triazine (prometryne) as a sulfur nutrient source. Other soil fungal isolates not affected by prometryne concentrations to 1 mg/ml culture included: Aspergillus oryzae (Ahlburg) Cohn, Curvularia lunata (Wakker) Boedijn, Tric...

A rapid procedure is described for determining total iron-binding capacity (TIBC) by use of a small, disposable resin column. Serum is saturated with excess ferric citrate, and iron not bound to protein is then removed by passing the mixture through the column of anion-exchanger. Transferrin-bound iron in the effluent, the TIBC, is determined colorimetrically (AutoAnalyzer), with 2,4,6-tripyrid...
