Novel chelate complexes of Co(II), Ni(II), Cu(II), Pd(II) derived from anti- and syn-isomers of 2-(2-aminothiazole-4-yl)-2-hydroxyiminoacetic acid with pro-/antiproliferative actions on endothelial cells

Anti- and syn-isomers of 2-(2-aminothiazole-4-yl)-2-hydroxyiminoacetic acid (anti-A and syn-A respectively) were used as potential biologically active polydentate complexing agent for Co2+, Ni2+, Cu2+ and Pd2+ ions for the synthesis of novel complex compounds with directed angiogenesis-correcting action. It shown that the location of functional groups in ligand molecules, the electronic structure of metal as complexing agent and the synthesis conditions affect the localization of coordination bonds and the structure of formed complexes. The interaction of ethanol solutions of metal salts with anti-A and syn-A in an acidic medium at the component ratios M:L = 1:1 and 1:2 leads to the formation of complexes [Co(anti-A)(H2O)3SO4] (1); [Ni(anti-A)(H2O)3SO4] (2); [Cu(anti-A)2Cl2] (3); [Pd(anti-A)2Cl2] (4); [Cu(syn-A)2Cl2] (5); [Pd(syn-A)Cl2] (6) with different coordination of ligands. Coordination mode of ligands identified by IR, UV-Vis, XPS and 1H (13C) NMR spectra. The structures of salt of the anti-A and complexes 1, 2, 6 were determined by X-ray diffraction study. Anti-A is coordinated to metal ions in a chelate manner by the nitrogen atom of the hydroxylimino group and the oxygen atom of the deprotonated carboxyl group. In this case, the 2-aminothiazole fragment does not involve in complexation. Syn-A is coordinated to the central metal ion in neutral form through the nitrogen atoms of hydroxyimino group and thiazole ring. All synthesized complex compounds form stable solutions in neutral medium, which makes it possible to use them as potential biologically active substances. Investigation of biological effects for syn-A shows mitogenic and antiapoptotic activity against endotheliocytes, while anti-A causes inhibition of proliferation almost in the entire concentration range. Complex compounds of Cu2+ and Pd2+ with anti-A and syn-A (3-6) cause an increase of antiproliferative activity of endothelial cells compared with baseline complexing agents. In this case, the activity of complexes with syn-A is superior to activity of analogues with anti-A. The results of cytotoxicity tests revealed a pronounced cytotoxic action for complexes 3 and 4, cytotoxic and proapoptotic activity for 6 and cytostatic effect for 5. For all compounds investigated, a checkpoint from S to G2 has been established, which may indicate DNA replication disturbance or dysregulation in the endogenous signals of the cell cycle of endotheliocytes.

Synthesis of trisubstituted thiazoles by ligand-free palladium-catalyzed direct 5-arylation of 2,4-disubstituted thiazoles under conventional and microwave-assisted heating

Trisubstituted thiazoles were synthesized with excellent yields using ligand-free, palladium-catalyzed, direct 5-arylation of 2,4-disubstituted thiazole and conventional or microwave-assisted heating. The palladium-catalyzed reaction yields were significantly influenced by LiCl additive, solvent, and heating method. The reaction times were reduced dramatically by employing microwave radiation instead of conventional heating. The synthetic methods can be applied to diverse 2,4,5-trisubstituted thiazoles by varying the aryl bromide and disubstituted thiazole reactants.

Distinct responses to mechanical grinding and hydrostatic pressure in luminescent chromism of tetrathiazolylthiophene

Luminescent mechanochromism has been intensively studied in the past few years. However, the difference in the anisotropic grinding and the isotropic compression is not clearly distinguished in many cases, in spite of the importance of this discrimination for the application of such mechanochromic materials. We now report the distinct luminescent responses of a new organic fluorophore, tetrathiazolylthiophene, to these stresses. The multichromism is achieved over the entire visible region using the single fluorophore. The different mechanisms of a blue shift by grinding crystals and of a red shift under hydrostatic pressure are fully investigated, which includes a high-pressure single-crystal X-ray diffraction analysis. The anisotropic and isotropic modes of mechanical loading suppress and enhance the excimer formation, respectively, in the 3D hydrogen-bond network.

Effect of Aliphatic Aldehydes on Maillard Reaction between Cysteine and Xylose and Meaty Flavor Formation

The effect of aliphatic aldehydes on Maillard reaction and meaty flavor formation was investigated in cysteinexylose model systems. The Maillard reaction in the absence and presence of hexanal, (E)-2-heptenal, or (E,E)-2,4-decadienal, was carried out at 90?, pH 5.5 for 5 h. Changes in the concentrations of xylose, cysteine, initial reaction intermediates (2-threityl-4-carboxythiazolidine and Amadori rearrangement product of cysteine (Cys-Amadori)) with reaction time were determined by high performance liquid chromatography with evaporate light scattering detection (HPLC-ELSD). Also, changes in the pH and absorbance values at 294 and 420 nm of the reaction mixtures were monitored. Volatile flavor compounds in the 3 h reaction mixtures were compartaively analyzed by solid phase microextraction coupled with gas chromatography and mass spectrometry (SPME-GC-MS). As indicated by decreased concentrations of Cys-Amadori and 2-threityl-4-carboxythiazolidine in the presence of aliphatic aldehydes, all the three aldehydes showed inhibitory effects on the initial stage of the Maillard reaction, among which (E)-2-heptenal was the stongest inhibitor, followed by (E,E)-2,4-decadienal and hexanal. Additionally, hexanal also showed inhibitory effect on the intermediate and final stages of the Maillard reaction, as indicated by decreased absorbance at 294 and 420 nm. However, (E)-2-heptenal and (E,E)-2,4-decadienal accelerated both the intermediate and final stages, as indicated by increased absorbance values at 294 and 420 nm, with the latter being more effective than the former. On the other hand, the reaction systems in the presence of (E)-2-heptenal and (E,E)-2,4-decadienal produced a relatively greater amount of total volatile sulfur-containing compounds than the blank model system, and additionally produced some new alkyl chain sulfur-containing compounds and furane derivatives such as 2-hexylthiophene and 2-propylfuran as detected by GC-MS analysis, due to participation of the aldehydes in cysteine-xylose reaction and reaction of the aldehydes themselves in the buffered cysteine-xylose solution.
