Synthetic 2-aryl-3-((piperidin-1-yl) ethyl)thiazolidin-4-ones exhibit selective in vitro antitumoral activity and inhibit cancer cell growth in a preclinical model of glioblastoma multiforme

Glioblastoma multiforme (GBM) is the worst form of primary brain tumor, which has a high rate of infiltration and resistance to radiation and chemotherapy, resulting in poor prognosis for patients. Recent studies show that thiazolidinones have a wide range of pharmacological properties including antimicrobial, anti-inflammatory, anti-oxidant and anti-tumor. Here, we investigate the effect antiglioma in vitro of a panel of sixteen synthetic 2-aryl-3-((piperidin-1-yl) ethyl) thiazolidin-4-ones where 13 of these decreased the viability of glioma cells 30-65% (100 mu M) compared with controls. The most promising compounds such as 4d, 4l, 4m and 4p promoted glioma reduction of viability greater than 50%, were further tested at lower concentrations (12.5, 25, 50 and 100 mM). Also, the data showed that the compounds 4d, 4l, 4m and 4p induced cell death primarily through necrosis and late apoptosis mechanisms. Interestingly, none of these 2-aryl-3-((piperidin-1-yl) ethyl) thiazolidin-4-ones were cytotoxic for primary astrocytes, which were used as a non-transformed cell model, indicating selectivity. Our results also show that the treatment with sub-therapeutic doses of 2-aryl-3-((piperidin-1-yl) ethyl) thiazolidin-4-ones (4d, 4l and 4p) reduced in vivo glioma growth as well as malignant characteristics of implanted tumors such as intratumoral hemorrhage and peripheral pseudopalisading. Importantly, 2-ryl-3-((piperidin-1-yl) ethyl) thiazolidin-4-ones treatment did not induce mortality or peripheral damage to animals. Finally, 2-aryl-3-((piperidin-1-yl) ethyl) thiazolidin-4-ones also changed the nitric oxide metabolism which may be associated with reduced growth and malignity characteristics of gliomas. These data indicates for the first time the therapeutic potential of synthetic 2-aryl-3-((piperidin-1-yl) ethyl) thiazolidin-4-ones to GBM treatment. (C) 2017 Elsevier B.V. All rights reserved.

5,6,7,8-Tetrahydronaphthalen-1-amine as Precursor for Thiazolidinones and Benzothiazepinones: Synthesis and Atropisomeric Relationship

The one-pot reaction of 5,6,7,8-tetrahydronaphthalen-1-amine, mercaptoacetic acid, and arenealdehydes having strong and weak electron-withdrawing groups gave the corresponding 1,3-thiazolidin-4-ones (47-70%). When arenealdehydes bearing strong and weak electron-donating groups were used as precursors, the 1,4-benzothiazepin-2-ones were obtained (30-72%) by p-TsOH catalysis. All compounds are unknown and were characterized by GC-MS and NMR techniques, and available crystals by X-ray diffraction studies. The atropisomerism phenomenon was observed in several 1,3-thiazolidin-4-ones as confirmed by VTNMR method. The Tc was established as 332 K and the energy required for the interconversion of one atropisomer into another is around 16.8 kcal.mol(-1). Chemical quantum calculation and NOESY displayed that more stable isomer has the tetrahydronaphthalene portion below the five-ring plane. Only a small difference between isomers (-0.21 to -0.84 kcal.mol(-1)) was observed by calculated energy.

OPTIMIZATION OF THE SYNTHESIS OF SOME NEW THIAZOLIDINE-4-ONE DERIVATIVES WITH XANTHINE SCAFFOLD

In the last time many researchers were focused on synthesis of new compounds with thiazolidine-4-one scaffold based on the important biological effects of this heterocycle. Aim: The aim of this study was to optimize the synthesis of some new thiazolidine-4-one derivatives with xanthine scaffold in order to obtain high yields and advanced purity. Material and methods: The synthesis was based on a cyclization reaction between various hydrazones and thioglycolic acid. The optimization was performed for 2-(4-methylphenyl)-3-[(1,3-dimethylxanthin-7-yl)acetamido]thiazolidine-4-one (b) by varying different parameters such as molar ratio between reagents, solvent, catalyst, temperature, time of reaction and type of method. There were used ten chemistry procedures for detecting the desired compound and other ones for establishing the optimal conditions. The optimized method was also applied for other thiazolidine-4-one derivatives with xanthine structure. Results: The most favorable parameters for optimal synthesis were established as follow: an excess of 20 equivalents of thioglycolic acid to 1 equivalent of hydrazone, freshly distilled toluene as solvent, temperature of 120 degrees C and reflux for 18 hours. The time and temperature of reaction proved to have a key role for increased yield. Conclusions: The optimal conditions of reaction were established in order to obtain new thiazolidine-4-one derivatives in high yields and increased purity.

Design, synthesis, in silico studies and biological evaluation of 5-((E)-4-((E)-(substituted aryl/alkyl)methyl)benzylidene)thiazolidine-2,4-dione derivatives

Background: Looking at the extensive biological potential of thiazolidine-2,4-dione (TZD) moiety, a new series of thiazolidine-2,4-dione analogues was synthesized. Different spectral techniques (H-1-NMR, IR, MS etc.) were used to confirm the chemical structures of the synthesized analogues. These synthesized compounds were screened for their antioxidant and antimicrobial potential. Results and discussion: The antimicrobial screening was carried out against selected strains of fungi and bacteria using serial tube dilution method. The antioxidant potential was assessed using stable 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging method. Further, the interaction between synthesized thiazolidine-2,4-dione compounds and DNA gyrase was explored using molecular docking studies. Various ADME parameters were also studied to evaluate the drug likeness of the synthesized compounds. Conclusion: In antimicrobial evaluation, the compounds 4, 9, 11, 12, 13, 15 and 16 displayed promising activity against selected strains of microbes. Antioxidant evaluation found compound 6 having IC50 = 9.18 mu g/mL to be the most potent compound in the series. The molecular docking study revealed compounds 4 (dock score = -4.73) and 7 (dock score = -4.61) with decent docking score, possess good interaction inside the ATP binding pocket of DNA gyrase and therefore can be used as lead structure for further optimizing into potent antimicrobial molecule.

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.
