Synthesis, Characterization and Molecular Docking of Novel Bioactive Thiazolyl-Thiazole Derivatives as Promising Cytotoxic Antitumor Drug

Reactions of ethylidenethiocarbohydrazide with hydrazonoyl halides gave 1,3-thiazole or 1,3,4-thiadiazole derivatives according to the type of hydrazonoyl halides. Treatment of ethylidenethiosemicarbazide with hydrazonoyl halides and dimethylacetylene dicarboxylate (DMAD) afforded the corresponding arylazothiazoles and 1,3-thiazolidin-4-one derivatives, respectively. The structures of the synthesized products were confirmed by IR, H-1-NMR, C-13-NMR and mass spectral techniques. The cytotoxic activity of the selected products against the Hepatic carcinoma cell line (Hepg-2) was determined by MTT assay indicating a concentration dependent cellular growth inhibitory effect, especially for compounds 14c and 14e. The dose response curves indicated the IC50 (the concentration of test compounds required to kill 50% of cell population) were 0.54 M and 0.50 M, respectively. Confocal laser scanning imaging of the treated cells stained by Rhodamin 123 and Acridine orange dyes confirmed that the selected compounds inhibit the mitochondrial lactate dehydrogenase enzymes. The binding mode of the active compounds was interpreted by a molecular docking study. The obtained results revealed promising cytotoxic activity.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 97-90-5 is helpful to your research. Product Details of 97-90-5.

Resveratrol and Its Analogs as Antitumoral Agents for Breast Cancer Treatment

Resveratrol (3,5,4′-tri-hydroxystilbene) (RSV), a naturally occurring phytoalexin, readily available in the diet, has gained interest as a non-toxic agent capable of displaying cancer-preventing and anti-cancer properties. Several studies, using both in vitro and in vivo models, have illustrated RSV capacity to modulate a multitude of signaling pathways associated with cellular growth and division, apoptosis, angiogenesis, invasion and metastasis. However, its clinical application is limited because of a low oral bioavailability with high adsorption but rapid metabolism and low tissue concentrations. Several chemical modifications to the backbone structure have been made for the purpose of improving pharmacokinetic parameters. One promising strategy involves the introduction of methoxylic or hydroxylic groups on the phenylic rings of RSV. Moreover, by replacing the alkene linker between the two aromatic rings with a heterocyclic system rigid analogs such as 2,3-thiazolidin-4-ones and 3-chloro-azetidin-2-ones that displayed higher cytotoxic activity and hence higher ability to inhibit in vitro breast cancer cell growth have been synthesized. In vitro studies have demonstrated, for some of these compounds, a greater bioaccessibility than RSV and more selective inhibitory effects on breast cancer cell growth. Further investigations, particularly in vivo, are required as next step to implicate these analogs as pharmacologic agents for a possible clinical anticancer application.

Preparation and characterization of Fe3O4@SiO2/APTPOSS core-shell composite nanomagnetics as a novel family of reusable catalysts and their application in the one-pot synthesis of 1,3-thiazolidin-4-one derivatives

Octakis[3-(3-aminopropyltriethoxysilane)propyl]octasilsesquioxane (APTPOSS) as a polyhedral oligomeric silsesquioxane derivative was prepared and used as a pioneer reagent to obtain a novel core-shell composite using magnetic iron oxide nanoparticles as the core and the inorganic-organic hybrid polyhedral oligomeric silsesquioxane as the shell. Fe3O4@SiO2/APTPOSS were confirmed using Fourier transform infrared spectroscopy, scanning electron microscopy, energy dispersive spectroscopy, dynamic light scattering, thermogravimetric analysis, X-ray diffraction and vibrating sample magnetometry. The inorganic-organic hybrid polyhedral oligomeric silsesquioxane magnetic nanoparticles were used as an efficient new heterogeneous catalyst for the onepot three-component synthesis of 1,3-thiazolidin-4-ones under solvent-free conditions. Moreover, these nanoparticles could be easily separated using an external magnet and then reused several times without significant loss of catalytic activity.

Unexpected complexation of allylpseudothiohydantoin hydrochlorides towards CuX (X=Cl, NO3, ClO4, BF4, 1/2SiF(6)). The first known examples of joint Cu-I(Cl,ClO4) and Cu-I(Cl,BF4) -complexes

By means of alternating current-electrochemical synthesis starting from a mixture of 2-imino-3-(prop-2-en-1-yl)-1,3-thiazolidin-4-one (3-allylpseudothiohydantoin, napt) and 2-allylamino-1,3-thiazol-4(5H)-one (allylaminopseudothiohydantoin, aapt) hydrochlorides and corresponding copper(II) salts five new -complexes, [Cu(napt)Cl] (1), [Cu-2(aapt)(2)Cl]NO3 (2), [Cu-2(aapt)(2)Cl]BF4 (3), [Cu-2(aapt)(2)Cl]ClO4 (4) and [Cu-2(aapt)(2)Cl](2)SiF(6)2H(2)O (5), were obtained and studied by X-ray single crystal diffraction and IR-spectroscopy. Napt and aapt molecules are selectively coordinated to Cu+ depending on the anion type. In crystals of 1 and 5, the organic ligands are attached to the metal in a chelating N,(C=C)-bidentate mode. The aapt molecule in 2-4 acts as a tridentate chelating ligand, being coordinated to the copper(I) ion through the heterocyclic N atom, carbonyl O atom, and C=Cbond of allyl group, forming an original cationic [Cu-2(aapt)(2)Cl](+) fragment with both a bridging Cl- ion and O atom of the C=O group. In the presence of the doubly charged SiF62- anion, Cu(I) in 5 prefers to be bonded with two bridging Cl- ions, rather than the C=O group, causing [Cu-2(aapt)(2)Cl](+) units to associate into the infinite cationic chains. Crystals of 3 and 4 are the first known examples of the simultaneous BF4-/Cl- or ClO4-/Cl- participation in copper(I) -complex formation. [GRAPHICS]

Synthesis and Crystal Structures of Some Pyridyl Aminothiazole and Thiazolidin-2-ylidene Benzamide Derivatives

Background: Thiazoles and their derivatives are attracting continuing interest over the years because of their varied biological activities. Thiazole and in particular the 2-amino thiazole moiety has been incorporated into a wide variety of therapeutically interesting candidates including antibacterial, anti-HIV, hypertension, anti-inflamenmatory, anti-viral and anticancer agents. Methods: Several methods for the synthesis of thiazole derivatives have been developed. The most widely used method being the Hantzch’s synthesis. In this paper, we describe an efficient one-pot method for the synthesis of some thiazolidin-2-ylidene benzamide and aminothiazole derivatives via condensation of 3-aminopyridine or 2-aminopyridine with phenacyl bromide and benzoyl isothiocyanates. Results: The reaction of 3-aminopyridine, benzoyl isothiocyanates, and phenacyl bromide in the presence of triethylamine yields thiazolidin-2-ylidene benzamides, which upon heating in acetic acid produce pyridyl aminothiazole derivatives. Also the pyridyl aminothiazole derivatives were obtained by the reaction of 2-aminopyridine with benzoyl isothiocyanates and phenacyl bromide in the presence of triethylamine. The molecular structures of the 4-chloro-N-(4-hydroxy-4-phenyl-3-(pyridin-3-yl)thiazolidin-2-ylidene)benzamide, phenyl(4-phenyl-2-(pyridin-3-ylamino)thiazol-5-yl)methanone and (4-phenyl-2-(pyridin-2-yl amino)thiazol-5-yl)(o-tolyl)methanone, have been fully determined by means of single crystal Xray diffraction methods. Conclusion: In summary, present study reports one-pot synthesis of thiazolidin-2-ylidene substituted benzamide and pyridyl aminothiazole derivatives via condensation of 3-aminopyridine or 2-aminopyridine with phenacyl bromide and substituted benzoyl isothiocyanates. The single crystal X-Ray diffraction analysis reveals unequivocally the exact identity of the compounds.
