Synthesis of tetracyclic azasugars fused benzo[e][1,3]thiazin-4-one by the tandem Staudinger/aza-Wittig/cyclization and their HIV-RT inhibitory activity

Azasugar aldehydes 6a and 6b containing azido groups were prepared from D-mannose. Three novel tetracyclic azasugars fused benzo[e][1,3] thiazin-4-one 9a-1, 9a-2 and 9a-3 were conveniently synthesized from 6a by the tandem intramolecular Staudinger/aza-Wittig/cyclization reaction under microwave radiation. Two unexpected elimination compounds 8b-1 and 8b-2 were achieved as the main products from 6b in the same processes. The newly synthesized azasugars were examined for their HIV reverse transcriptase (RT) inhibitory activities. The results showed that all the tested compounds could effectively inhibit RT activity. Among them, compound 8b-1 with the protective group (isopropylidene group) was the best one with the IC50 value of 0.76 mu M. The structure activity relationship analysis suggested that improvement of the molecular hydrophilicity might be beneficial for their anti-HIV RT activities. (C) 2017 Elsevier Ltd.

Novel immunostimulators with a thiazolidin-4-one ring promote the immunostimulatory effect of human iNKT cells on the stimulation of Th2-like immune responsiveness via GATA3 activation in vitro

Invariant natural killer T cells (iNKTs) are important innate immune cells which get involved in various immune responses in both mice and humans. These immune reactions range from self-tolerance to development of auto immunity and responses to pathogens and tumor development. In this study, we aimed to explore the effects of the novel immunostimulators (CH1b and CH2b) containing thiazolidin-4-one on the functions of human invariant natural killer T cells (iNKTs). First of all, iNKTs in peripheral blood mononuclear cells were expanded with alpha-Galactosylceramide (alpha-Galcer) in vitro. Then, the highly purified iNKTs were isolated from PBMCs using magnetic cells sorting (MACS). Next, we investigated the impacts of CH1b and CH2b on proliferation, cytokines production, cytotoxicity, and the associated signaling pathways in iNKT cells. Finally, we found that CH2b could significantly promote the activated iNKTs proliferation, increase the production of Th2 cytokines, and induce Th0 differentiation into Th2 subset via GATA3 signaling pathway. Besides, CH2b could markedly enhance the cytotoxic ability of the activated iNKTs. Therefore, we concluded that CH2b, a promising candidate immunostimulator, might be used for the treatment of infections, tumors, autoimmune and allergic diseases, and for the correction of Th1/Th2 balance disorders in future.

2-(Thienothiazolylimino)-1,3-thiazolidin-4-ones inhibit cell division cycle 25 A phosphatase

Cell division cycle dual phosphatases (CDC25) are essential enzymes that regulate cell progression in cell cycle. Three isoforms exist as CDC25A, B and C. Over-expression of each CDC25 enzyme is found in cancers of diverse origins. Thiazolidinone derivatives have been reported to display anti-proliferative activities, bactericidal activities and to reduce inflammation process. New 2-(thienothiazolylimino)-1,3-thiazolidin-4-ones were synthesized and evaluated as inhibitors of CDC25 phosphatase. Among the molecules tested, compound 6 inhibited CDC25A with an IC50 estimated at 6.2 +/- 1.0 mu M. The binding of thiazolidinone derivative 6 onto CDC25A protein was reversible. In cellulo, compound 6 treatment led to MCF7 and MDA-MB-231 cell growth arrest. To our knowledge, it is the first time that such 4-thiazolidinone derivatives are characterized as CDC25 potential inhibitor. (C) 2016 Elsevier Ltd. All rights reserved.

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.

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.

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.
