Corrosion Inhibition of Stainless Steel Type 316 L in 1.0 M HCl Solution Using 1,3-Thiazolidin-5-one Derivatives

Ten compounds of 1,3-thiazolidin-5-one derivatives has been evaluated as an inhibitor for corrosion of stainless steel type 316L (316SS) in 1.0 M HCl solution by means of weight loss and electrochemical impedance spectroscopy techniques. The surface examination and morphological studies were studied using scanning electron microscope (SEM) and energy dispersive X-ray (EDX). It has been found that the percentage inhibition efficiency increases with increasing the concentration of inhibitors and with decreasing temperature. These compounds acted as mixed type inhibitors. The inhibition process was explained due to the adsorption of these compounds at the 316 SS surface. The adsorption obeys Temkin’s isotherm. The effect of substituted group and substituted position on the inhibition efficiency were explained. SEM and EDS confirmed that the rate of 316SS corrosion in1.0 M HCl solution is reduced due to the formation of the protective film on its surface.

This paper report is an analysis of the title compound by means of X-ray crystallography, FT-IR, NMR and DFT calculations, in the context of structural and spectral characterization. The crystal and molecular structures of the compound were determined by single-crystal X-ray diffraction (SCXRD). Fourier Transform Infrared (FTIR) spectrum was recorded in the range from 400 cm(-1) to 4000 cm(-1). The H-1 and C-13 nuclear magnetic resonance (NMR) spectra were also recorded. DFT calculations were employed to support X-ray molecular geometry and calculate IR and NMR (H-1 and C-13) spectral bands. The structural (bond lengths, bond angles, torsion angles) and spectral (vibrational modes and chemical shifts) parameters obtained from DFT levels (B3LYP/6-31G(d,p) and B3LYP/6-31G+(d,p)) were compared with experimental findings, and an excellent harmony between the two data was ascertained.

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.

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.

Further insight into the dual COX-2 and 15-LOX anti-inflammatory activity of 1,3,4-thiadiazole-thiazolidinone hybrids: The contribution of the substituents at 5th positions is size dependent

Herin we report the design, synthesis, full characterization and biological investigation of new 15-LOX/COX dual inhibitors based on 1,3-thiazolidin-4-one (15-lipoxygenase pharmacophore) and 1,3,4-thiadiazole (COX pharmacophore) scaffolds. This series of molecular modifications is an extension of a previously reported series to further explore the structural activity relationship. Compounds 3a, 4e, 4n, 4q, 7 and 8 capable of inhibiting 15-LOX at (2.74, 4.2, 3.41, 10.21, 3.71 and 3.36 mu M, respectively) and COX-2 at (0.32, 0.28, 0.28, 0.1, 0.28 and 0.27 mu M, respectively). The results revealed that binding to 15-LOX and COX is sensitive to the bulkiness of the substituents at the 5 positions. 15-LOX bind better with small substituents, while COXs bind better with bulky substituents. Compounds 3a, 4r and 4q showed comparable in vivo anti-inflammatory activity to the reference drug (celecoxib). The ulcer liability test showed no sign of ulceration which ensures the safe gastric profile. Docking study was performed to explore the possible mode of interaction of the new compounds with the active site of human 15-LOX and COX-2. This study discloses some structural features for binding to 15-LOX and COX, thus pave the way to design anti-inflammatory agents with balanced dual inhibition of these enzymes.

Phytochemical profiling and effect of Andrographis echioides (L.) Nees leaf extract on glucose uptake by 3T3-L1 cell lines – An in vitro study

The human population worldwide appears to be in the midst of an epidemic of diabetes, a metabolic disorder characterised by problems in carbohydrate metabolism. The existing synthetic drugs have several limitations such as, diabetic retinopathy, nephropathy and neuropathy. Thus, in spite of remarkable progress in the treatment of diabetes by oral hypoglycemic agents, search for newer drugs continues. Hence, in the present study, Andrographis echioides (L.) Nees was examined for its in vitro antidiabetic efficacy by amylase inhibition and glucose uptake by 3T3 cell lines assays. In addition, the bioactive components were analysed by GC-MS technique. The data obtained suggests that methanol extract of A. echioides was effective in enhancing glucose uptake by the 3T3 cell lines in vitro. The GC-MS profile revealed the presence of 5-ethyl-2-imino thiazolidin-4-one recorded at 15.95min. Literature survey has proved that thiazolidin-4-one derivatives have important biological activities and thus, the antidiabetic potential of A. echioides can be related to its presence. Further mechanistic studies could be taken up to prove the effect in vivo.

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.
