triazine derivatives are small synthetic peptides with no apparent toxicity and high target specificity in central nervous system. hippocampal tissue is the most vulnerable area in the alzheimer’s disease (ad). the aim of this study was to investigate the neuroprotective effect of triazine in ad induced by intra-cerebro-ventricular (i.c.v.) administration of streptozotocine (stz). male wistar, ...

Enantioselective syntheses from dimethyl tartrate of 1,3,5-triazine homo-N-nucleoside analogs, containing a 1,4-dioxane moiety replacing the sugar unit in natural nucleosides, were accomplished. The triazine heterocycle in the nucleoside analogs was further substituted with combinations of NH(2), OH and Cl in the 2,4-triazine positions.

Covalent triazine frameworks, which are crosslinked porous polymers with two-dimensional molecular structures, are promising materials for heterogeneous catalysts. However, the application of the frameworks as electrocatalysts has not been achieved to date because of their poor electrical conductivity. Here we report that platinum-modified covalent triazine frameworks hybridized with conductive...

the properties relevant to pharmacokinetics and pharmacodynamics of four series of synthesized s-triazine derivatives have been studied by quantitative structure-retention relationship (qsrr) approach. the chromatographic behavior of these compounds was investigated by using reversed-phase high performance thin-layer chromatography (rp-hptlc). chromatographic retention (rm0) was correlated with...

To help elucidate the mechanism of dechlorination of chlorinated triazines via metallic iron, terbutylazine (TBA: 2-chloro-4-ethylamino-6-terbutylamino-1,3,5-triazine), deisopropyl atrazine (DIA: 2-amino-4-chloro-6-ethylamino-1,3,5-triazine), and chlorinated dimethoxy triazine (CDMT: 2-chloro-4,6-dimethoxy-1,3,5-triazine) were degraded via zero valent iron under controlled pH conditions. The lo...

In the title methanol-solvated salt, C14H19Cl3N5O2 (+)·Cl(-)·CH3OH, the triazine mol-ecule is protonated at one of the triazine N atoms. In the crystal, the triazine cations are linked through a pair of N-H⋯N hydrogen bonds, with graph-set R 2 (2)(8), forming an inversion dimer. The protonated N atom and the 2- and 4-amino groups of the triazine cation inter-act with the chloride anion through ...

In the title 1,2,4-triazine derivative, C(17)H(19)N(3)O(3), the heterocyclic ring is planar (r.m.s. deviation = 0.040 Å) and effectively coplanar with the adjacent phenyl ring [dihedral angle = 4.5 (2)°] but almost perpendicular to the (cyclo-hex-3-en-1-ylmeth-oxy)methyl residue [N-N-C-O torsion angle = 71.6 (5)°], so that the mol-ecule has an 'L' shape. Supra-molecular chains along [001] are f...

A series of 1,2,4-triazine derivatives Va (1-24) and Vb (1-24) were synthesized and evaluated for their anti-anxiety and anti-inflammatory activities. The structures of the synthesized compounds were confirmed on the basis of their spectral data. Many of the triazine compounds were found to possess good activity. Especially, compounds bearing the sulfur atom showed better activity than those be...

A new dimension: The doping of amorphous poly(triazine imide) (PTI) through ionothermal copolymerization of dicyandiamide with 4-amino-2,6-dihydroxypyrimidine (4AP) results in triazine-based carbon nitrides with increased photoactivity for water splitting compared to crystalline poly(triazine imide) (PTI/Li(+)Cl(-), see picture) and melon-type carbon nitrides. This family of carbon nitride semi...
