Novel glycosidic compounds, 4,6-dialkoxy-1,3,5-triazin-2-yl β-lactosides (DAT-β-Lac), have been prepared directly in water from lactose. The reaction was carried out on a laboratory scale without protecting the hydroxy groups of lactose. The resulting triazine derivatives were found to be recognized by endo-β1,4-glucanase III from Trichoderma reesei (EGIII). The EGIII-catalysed transglycosylati...

In the title mol-ecule, C(12)H(12)N(4)O(3)S, there is an intra-molecular O-H⋯N hydrogen bond. The dihedral angle between the benzene and triazine rings is 65.9 (3)°. In the crystal, N-H⋯S and O-H⋯N hydrogen bonds link the mol-ecules into chains along [010]. In addition, there are weak π-π stacking inter-actions between symmetry-related triazine rings with a centroid-centroid distance of 3.560 (...

The mol-ecule of the title compound, C(18)H(21)N(9), is nearly planar, with the three pyrazole rings aligned at 2.40 (5), 9.27 (5) and 9.71 (5)° with respect to the triazine ring. The triazine ring is planar (r.m.s. deviation = 0.005 Å), the distortion from a hexa-gonal arrangement arising from the angles at the N [112.4 (1)-113.1 (1)°] and C [127.1 (1)-127.6 (1)°] atoms deviating from 120°. Th...

Anion receptors bearing p electron-deficient arenes have attracted increasing interest during the past decade. The anion–p interaction between charge neutral electron-deficient aromatic rings, as predicted by theoreticians, has been evidenced experimentally both by solid state and solution investigations. For example, in the solid state, while weaks-interaction in which anions interact with p e...

The benzoic acid mol-ecule of the title adduct, C10H11N5·C7H6O2, is approximately planar, with a dihedral angle of 7.2 (3)° between the carb-oxy-lic acid group and the benzene ring. In the triazine mol-ecule, the plane of the triazine ring makes a dihedral angle of 28.85 (9)° with that of the adjacent benzene ring. In the crystal, the two components are linked by N-H⋯O and O-H⋯N hydrogen bonds ...

Triazine-resistant chloroplasts o f the Canadian spring oilseed rape variety OAC Triton were transferred into four German winter oilseed rape lines and two cultivars o f double-low quality by means o f protoplast fusion. X-irradiation has been used to reduce the amount o f nuclear D N A o f the spring type cultivar and to promote cybrid formation. RFLP-analysis showed that some regenerants and ...

2 The present work deals with the synthesis of some novel heterocyclic compounds such as benzoxazoles , 7, 13 and 19, imidazoles 3, 8, 14 and 20, benzimidazoles 4, 9, 15 and 21, and tetrazoles 10, 16, and 22. The synthesized compounds were characterized by IR, 1H NMR, mass spectrometry and elemental analysis. The compounds were evaluated for cytotoxicity against human cancer cell lines such as ...

The Bernal (ABA)-stacked graphene trilayer is presumed to be thermodynamically more stable than the rhombohedral (ABC) counterpart. However, the thermal transformation from ABC to ABA domains does not occur at a temperature lower than 1,000 °C. Here we report that ABC-stacked trilayers are transformed to ABA-stacked layers after an organic molecule triazine is evaporated onto graphene surfaces ...

The aim of this study was to formulate and evaluate an experimental adhesive resin with the addition of 1,3,5-triacryloylhexahydro-1,3,5-triazine at different concentrations. Experimental adhesive resins were obtained by mixing 50% wt bisphenol A glycol dimethacrylate (BisGMA), 25% wt triethylene glycol dimethacrylate (TEGDMA), 25% wt 2-hydroxyethyl methacrylate (HEMA) and photoinitiator system...

For functional nitrogen-bridged calix(hetero)aromatic platforms to be further used in the design of more sophisticated receptors, the azacalix[2]arene[2]triazine nitrogen bridges were functionalised with methyl bromoacetate. Three new macrocycles with four N-methyl ester pendant arms were straightforwardly prepared in good yields from the undecorated azacalix[2]arene[2]triazine precursors with ...
