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.

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.

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.

Evaluation of new 2-hydroxy-N-(4-oxo-2-substituted phenyl-1,3- thiazolidin-3-yl)-2-phenylacetamide derivatives as potential antimycobacterial agents

A small collection of 2-hydroxy-N-(5-methyl/nonsubstituted 4-oxo-2-substituted phenyl-1,3-thiazolidin-3-yl)-2-phenylacetamides (3-16) was synthesized from the cyclocondensation of 2-hydroxy-2-phenyl-N’-[(substitutedphenyl)methylene]acetohydrazides (2) and mercaptoethanoic acid or 2-mercaptopropanoic acid, characterized with spectral and elemental analysis. In order to explore their antimycobacterial potential, newly synthesized fourteen compounds were screened for their inhibitory activity against Mycobacterium tuberculosis strain H37Rv at 6.25 mu g/mL with in-vitro primary tests. Compound 7 was found to provide the highest inhibition (98%) M. tuberculosis strain H37Rv, while most of the new derivatives showed different inhibition ratios. For the search of the putative targets which are considered as related to the antimycobacterial activity of these molecules, docking studies were performed. With molecular dynamic simulations, further possible interactions between ligands and the active site of the selected enzymes were investigated. Eventually, molecular modelling studies indicated that at least part of the mechanism of action of these compounds may be mediated by inhibition of MtInhA.

Rapid induction of apoptosis in tumor cells treated with a new platinum(II) complex based on amino-thiazolidinone

Thiazolidinone derivatives have been previously shown significant anti-cancer activities. Two aminothiazolidinone complexes, (Pt(HTone)Cl] (1) and [Cu(HTone)Cl] (3) (HTone = (Z)-2-((E)-(1-(pyridin-2-yl)ethylidene)hydrazono)thiazolidin-4-one) and one ethyl-modified [Pt(ETone)Cl-2] (2) (ETone = (Z)-3ethyl-2-((E)-(1-(pyridin-2-yl)ethylidene) hydrazono)thiazolidin-4-one)], were designed and synthesized in order to explore novel metal-based antitumor agents. MTT assay indicated that 1 and 3 were markedly cytotoxic to MCF-7, HepG-2 and NCI-H460 tumor cells, superior to both cisplatin and the HTone ligand. Massive dead cells were observed as early as 6 h when treated with 1, indicating rapid action of 1 as compared to that of other compounds. More interestingly, Hoechst 33342 staining and flow cytometry analysis illustrated that only complex 1 could induce obvious cell apoptosis within 12 h, which was associated with the high-expression of Bax and cleavage of caspase-3 from 35 kDa to 17 kDa. By means of ICP-MS assay, we found complex 1 could largely accumulate in tumor cells in a short time. Additionally, complex I showed no cross resistance against the cisplatin-resistant cells.

Design, graph theoretical analysis, density functionality theories, Insilico modeling, synthesis, characterization and biological activities of novel thiazole fused quinazolinone derivatives

A series of 2-(2-substituted benzylidenehydrazinyl-2-oxopropyl)-3-(4-[4-oxo-2-phenylthiazolo din-3-yl]phenyl)quinazolin-4(3H)-one 7a-7l were synthesized and characterized by IR, H-1-NMR, C-13-NMR, mass spectroscopy and elemental analyses. In this present study, the density functionality theory was performed to identify drug stability. Further we introduced graph theoretical analysis by utilised Kyoto Encyclopedia of Genes and Genomes (KEGG) database and Cytoscape software to identify drug target. Based on the observed drug target insilico modeling was executed to know effective drug. The antiepileptic effects of title compounds were evaluated by using MES and subcutaneous pentylenetetrazole (scPTZ) test. Acute neurological toxicity of title compounds was studied by using standardized rotorod test. After 0.5 hr of period many of the compounds showed anticonvulsant activity at MES or scPTZ test. Comparison of the biological activity of test compounds with its chemical structures indicates that, compounds possessing electron donating group exhibited superior activity than the analogs having electron withdrawing moieties. Among the electron donating group tested, amino derivative exhibited good activity than rest of derivatives. From the study it was concluded that, the compound 7j was established as very potent compared with rest of the compounds and standard drugs subjected to biological studies. Thus the compound 2-(2-[4-aminobenzylidene]hydrazinyl-2-oxopropyl)-3-(4-[4-oxo-2-phenylthiazolidin-3-yl]phenyl) quinazolin-4(3H)-one (7j) came out as pilot derivative without any neurotoxicity with a wide spectrum of antiepileptic activity.
