A new facile mol. sensor (HL), 4-((3-(cyclohexylamino)propylimino)methyl)-5-(hydroxymethyl)-2-methylpyridin-3-ol, constructed with pyridoxal moiety, selectively detects Zn2+ ion in solid and solution medium. The structure of this newly synthesized sensor is confirmed by single crystal X-ray diffraction study. The rapid selective fluorescence ′turn-on′ response of Zn2+ ion in aqueous ethanolic (9:1, volume/volume) HEPES buffer (pH = 7.0) medium was studied. The synthesized mol. sensor shows the lowest limit of detection (LOD) for Zn2+ ion (9.5850 ± 0.3835 nM). The sensing behavior of the mol. sensor towards Zn2+ can be ascribed to the formation of complex. D. functional theory (DFT) and time dependent d. functional theory (TD-DFT) calculations were carried out to support the proposed tetrahedral geometry of zinc(II) complex and to explore the electronic properties of HL and its zinc complex (ZnL2). The mol. sensor shows the practical application to detect zinc(II) qual. on TLC plate based test strips. In addition to that, it also gives insight into the design of protocols required for successful imaging of intracellular zinc(II) ions in HeLa cells.

Root metabolic plasticity underlies functional diversity in mycorrhiza-enhanced stress tolerance in tomato was written by Rivero, Javier;Alvarez, Domingo;Flors, Victor;Azcon-Aguilar, Concepcion;Pozo, Maria J..

Summary : Arbuscular mycorrhizal (AM) symbioses can improve plant tolerance to multiple stresses. We compared three AM fungi (AMF) from different genera, one of them isolated from a dry and saline environment, in terms of their ability to increase tomato tolerance to moderate or severe drought or salt stress. Plant physiol. parameters and metabolic profiles were compared in order to find the mol. mechanisms underlying plant protection against stress. Mycorrhizal growth response was determined, and ultrahigh-performance LC-MS was used to compare the metabolic profile of plants under the different treatments. All AMF increased plant tolerance to stress, and the pos. effects of the symbiosis were correlated with the severity of the stress. The AMF isolated from the stressful environment was the most effective in improving plant tolerance to salt stress. Differentially accumulated compounds were identified and the antistress properties of some of them were confirmed. We demonstrate that AM symbioses increase plant metabolic plasticity to cope with stress. Some responses were common to all AMF tested, while others were specifically related to particular isolates. Important metabolism reprograming was evidenced upon salt stress, and we identified metabolic pathways and compounds differentially accumulated in mycorrhizas that may underlie their enhanced tolerance to stress.

Effect and mechanism of pyridoxamine on the lipid peroxidation and stability of polyunsaturated fatty acids in beef patties was written by Wong, Daniel;Hu, Xiaoqiang;Tao, Ningping;Wang, Xichang;Wang, Mingfu. And the article was included in Journal of the Science of Food and Agriculture in 2016.Application In Synthesis of 3-Hydroxy-5-(hydroxymethyl)-2-methylisonicotinaldehyde hydrochloride The following contents are mentioned in the article:

BACKGROUND : Little is known about how vitamins can affect the peroxidation and stability of polyunsaturated fatty acids in cooked foods. Thus the effects of 15 vitamins on toxic malondialdehyde (MDA) formation in cooked beef patties were examined with the application of solid phase extraction and thiobarbituric acid (TBA) anal. by HPLC-DAD. The polyunsaturated fatty acid profiles in cooked beef patties treated with some vitamins were further compared with that of control sample (no vitamin addition) by GC-MS anal. RESULTS : Pyridoxamine, pyridoxine, retinoic acid, α-tocopherol and L-ascorbic acid exhibited significant effects lowering the amount of MDA. It was further discovered that retinoic acid, α-tocopherol and L-ascorbic acid could help preserve polyunsaturated fatty acids, while pyridoxamine addition actually showed no effect upon the retention of most of the tested polyunsaturated fatty acids, even lowering the content of arachidonic acid. Further LC-MS anal. demonstrated that pyridoxamine could directly react with MDA via an addition reaction. The reaction involves a nucleophilic attack of pyridoxamine’s free amine group on one of the aldehyde functional groups of MDA to form a new adduct, and may accelerate lipid peroxidation with the loss of more polyunsaturated fatty acids. CONCLUSION : Some vitamins may directly participate in lipid peroxidation and affect food quality. © 2015 Society of Chem. Industry.

Although a variety of fluorescence based chemosensors have been utilized for selective detection of Zn2+, pyridoxal containing simple Schiff bases still remained less explored. Here, we combine pyridoxal hydrochloride and 1,2-diaminocyclohexane to generate a new sensor mol., H4PydChda (5-Hydroxymethyl-4-((2-(5-hydroxymethyl-2-methylpyridin-3-hydroxy-4-ylethylene)-amino)-cyclohexylimino)-methyl-2-methylpyridin-3-ol). Chemosensor H4PydChda exhibits selective turn-on type response in presence of Zn2+ in ethanol-water mixture at physiol. pH. Appreciable fluorescence enhancement occurs upon addition of Zn2+ to H4PydChda as a result of inhibited C=N isomerisation and excited state intramol. proton transfer leading to efficient chelation enhanced fluorescence. The relevant properties, including reversibility, life time measurements and detection limit have been determined for the sensor system. The exptl. and theor. supports in terms of 1H and 13C NMR spectroscopy and DFT/ TDDFT study are provided to establish the binding mode of H4PydChda to Zn2+. H4PydChda was employed as a sensor for detection of Zn2+ in Human gastric adenocarcinoma AGS cells.

Three hydroxymethyl bridged Cu(II) complexes of a pyridoxal Schiff base ligand 4-((E)-(2-(pyridin-2-yl)ethylimino)methyl)-5-(hydroxymethyl)-2-methylpyridin-3-ol (LH) were synthesized and characterized on the basis of spectroscopic, electrochem. and structural properties. The x-ray crystal structures of the complexes reveal dual denticity of the ligand, bidenticity in the absence of a co-ligand as in complex 1, and tridenticity in the presence of a co-ligand such as SCN/N(CN)2 as in complexes 2 and 3. The complexes, though binuclear in the solid state, exist as a monomeric unit in solution due to the exceptionally long axial Cu-Ohydroxymethyl (2.4-2.5 Å) bond. All three complexes show efficient catalytic activities towards the aerial oxidation of 3,5-di-tert-butylcatechol (DTBCH2) with kcat values of 5.38 x 104 h-1, 1.18 x 105 h-1 and 1.06 x 105 h-1 in methanol.

Topoisomerase (Topo) accelerates cell growth and division, and has been a theor. target for anti-cancer drugs for decades. A series of pyridoxal thiosemicarbazone (PLT) ligands were designed and synthesized, and the dependence of their antiproliferative activity on copper was investigated. The insertion of N-cyclohexyl-2-((3-hydroxy-5-(hydroxymethyl)-2-methylpyridin-4-yl)methylene)-N-methylhydrazinecarbothioamide hydrochloride (compound 9) and Chlorido(N-cyclohexyl-2-((3-hydroxy-5-(hydroxymethyl)-2-methylpyridin-4-yl)methylene)-N-methylhydrazinecarbothioamide hydrochloride-O,N,S)-copper(II) nitrate (9-Cu complex) into Topo-I and Topo-II prevented uncoiling of DNA through hydrogen bonds and intermol. forces. The combination of PLT derivatives and copper gluconate (CuGlu) improved their anti-tumor activity against a cell line with high expression of topoisomerase (SK-BR-3). The non-linear regression equations of the inhibitory activity and anti-tumor activity of Topo-I and Topo-II in SK-BR-3 cells had R2 values of 0.93 and 0.94, resp. In addition to lipophilicity, inhibition of topoisomerase also affected the activity of PLT ligands by coordinating with copper ions. At the cellular level, PLTs and CuGlu penetrate the cell membrane to form metabolites in the cell, thus selectively inhibiting the activity of Topo-I and Topo-II, and ultimately inhibiting cell division. These findings will inform the design of future anti-cancer thiosemicarbazone drugs.

A Co(II) complex of mol. formula C24H48.4N6O11.2CoCl, 1 CoL2·7.2H2O·Cl, was synthesized from the Schiff base [H2pydmdp]Cl by a template reaction of pyridoxal (pyd), a vitamer of vitamin B6, N-methyl-1,3-diaminopropane (mdp) and cobalt(II) acetate. It was characterized by elemental anal., 1H NMR, IR and UV-visible spectroscopy, thermal anal., electrochem. and single crystal x-ray diffraction. The exptl. results suggested that in complex 1, the central Co(II) is bonded to two phenolato-oxygens, two imine nitrogens and two amine nitrogens in an octahedral geometry. In aqueous media complex 1 exhibits an intense fluorescence emission peak at 506 nm when it was excited at 425 nm. The fluorescence behavior of complex 1 in aqueous media was employed to determine whether it acts as a chemosensor for some selective toxic metal ions. The present complex behaves as a promising sensor for Hg2+ even at the sub-micromolar level. In addition in aqueous solution, complex 1 acts as a sensor for the pH of the medium. A detailed study on the mechanism of sensing behavior established that Hg2+ interacts with complex 1 via weak noncovalent interaction with the N-atom of the pyridine moiety of the mol.

3-Hydroxy-5-(hydroxymethyl)-2-methylisonicotinaldehyde hydrochloride (cas: 65-22-5) belongs to alcohols. Under appropriate conditions, inorganic acids also react with alcohols to form esters. To form these esters, a wide variety of specialized reagents and conditions can be used. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.Name: 3-Hydroxy-5-(hydroxymethyl)-2-methylisonicotinaldehyde hydrochloride

Complexes of pyridoxal thiosemicarbazones formed with vanadium(IV/V) and copper(II): Solution equilibrium and structure was written by Jakusch, Tamas;Kozma, Karoly;Enyedy, Eva A.;May, Nora V.;Roller, Alexander;Kowol, Christian R.;Keppler, Bernhard K.;Kiss, Tamas.

The stoichiometry and thermodn. stability of vanadium(IV/V) and copper(II) complexes of pyridoxal thiosemicarbazone and pyridoxal-N3,N3-dimethylthiosemicarbazone were determined by pH-potentiometry (VIVO), EPR (VIVO/CuII), UV-visible (CuII, VIVO and VV) and 51V NMR spectroscopy (VV) in 30% (weight/weight) DMSO/water solvent mixture In all cases, mono-ligand complexes are formed in different protonation states. In addition, the proton-dissociation constants of the ligands were also determined by pH-potentiometry, UV-visible and 1H NMR spectroscopy. The solid state structures of the monoprotonated forms (VVO2(L1H)×1.5H2O) (1) and (VVO2(L2H)×0.8H2O) (2) of the VV complexes were characterized by single-crystal x-ray diffraction anal. The mono-ligand complexes of CuII and VV are dominant at physiol. pH. With all studied metal ions the pyridoxal moiety of the ligand causes an extra deprotonation step between pH 4 and 7 due to the non-coordinating pyridine-NH+. The pyridoxal-containing ligands form somewhat more stable complexes with both VIVO and CuII ions than the reference compound salicylaldehyde thiosemicarbazone. Dimethylation of the terminal amino group gave VV and CuII complexes with even higher stability. This study involved multiple reactions and reactants, such as 3-Hydroxy-5-(hydroxymethyl)-2-methylisonicotinaldehyde hydrochloride (cas: 65-22-5Name: 3-Hydroxy-5-(hydroxymethyl)-2-methylisonicotinaldehyde hydrochloride).

3-Hydroxy-5-(hydroxymethyl)-2-methylisonicotinaldehyde hydrochloride (cas: 65-22-5) belongs to alcohols. Under appropriate conditions, inorganic acids also react with alcohols to form esters. To form these esters, a wide variety of specialized reagents and conditions can be used. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.Name: 3-Hydroxy-5-(hydroxymethyl)-2-methylisonicotinaldehyde hydrochloride
