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.

Utilization of 2-Ylidene-4-Thiazolidinones in the Synthesis of Heterocyclic Compounds Part III: Synthesis and In-Vitro Antibacterial Activity Evaluation of Thienopyrimidinone Derivatives

3-Amino-2-thiophenecarboxamides (3a, d-g) were synthesized from 2-(4-oxo-3-phenyl- thiazolidin-2-ylidene)malononitrile (2) and employed in the synthesis of a variety of thiophene and thienopyrimidinone derivatives. 3 -Amino-2-thiophenecarboxamides (3a, d, e) on refluxing in acetic acid gave the tetrahydrothienopyrimidinones (6a-m). On the other hand, the reaction of the 3-amino-2-thiophenecarboxamides (3a, d, e) with triethylorthoformate or with formic acid produced the dihydrothienopyrimidinones (7a-c). The synthesized heterocyclic compounds were screened for antibacterial activities using narrow spectrum against gram-positive and gram-negative bacteria.

Comparative Evaluation of the Inhibitory Potential of Synthetic N-Heterocycles, Cu/Fe3O4@SiO2 Nanocomposites and Some Natural Products against Non-Resistant and Antibiotic-Resistant Acinetobacter baumannii

Background: Acinetohacler baumannii is a common infectious agent in hospitals. New antimicrobial agents are identified and prepared to combat these bacterial pathogens. In this context, the blocking potentials of a series of synthesized N-heterocyclic compounds, Cu/Fe3O4@SiO2 nanocomposites, glycine, poly-L-lysine, nisin and hydroalcoholic extracts of Trachyspermum ammi, Curcuma Tonga and green tea catechins were evaluated against nonresistant and multidrug-resistant strains of A. baumannii. Methods: Solutions of heterocyclic derivatives and hydroalcoholic extracts of Trachyspermurn ammi, Curcuma longa and green tea catechins were prepared at initial concentration of 10240 mu g ml(-1) in 10% DMSO. Other compounds were dissolved in water at the same concentrations. Their in vitro inhibitory activity was assessed by determination of IZD, MIC and MBC values. Results: Glycine, poly-L-lysine, nisin, Curcuma longa and green tea catechins extracts, and thiazoles 3a, 3d and 3f were ineffective at their initial concentrations. Heterocyclic derivatives 7a-f, 3c, 3c and 3h, Cu/Fe3O4@SiO2 nanocomposites and Trachyspermum ammi extract could block the growth of bacterial strains with IZDs (7.40-15.51 mm), MICs (32-1024 mu g ml(-1)) and MBCs (128-2048 mu g ml(-1)). Conclusion: Among synthetic chemicals and natural products, the best antimicrobial effects were recorded with (E)-2-(5-acelyl-4-methylthiazol-2-yl)-2-(thiazolidin-2-ylidene)acetonitrile (7b) and the extract of Trachyspermum ammi. It is imperative that their toxic and histopathologic effects were assessed in future researches. It is predicted that the essential oil of Trachyspermurn ammi will improve its antibacterial activities.

Silica catalyzed one pot synthesis of hybrid thiazolidin-4-one derivatives as anti-tubercular and anti-inflammatory agent by attenuating COX-2 pathway

A novel series of a hybrid class of hybrid thiazolidin-4-one derivatives were designed and synthesized through one-pot catalytic synthesis. The reaction was catalyzed in the presence of silica-H(2)SO4((+6)). The derivatives computational ADMET profile was calculated. The study shows that most active derivatives have optimal logP, higher anti-inflammatory activity score, and poor metabolism at the sight of P450-3A4 and 2D6. The entire series of derivatives were further evaluated for anti-tubercular (against Mycobacterium tuberculosis H37Rv (Resistant strain)) and anti-inflammatory activity (in-vivo assay using Wistar rat). The result showed that derivatives 4c, 4h, and 4m have significant potency against tested M. tuberculosis. However, derivatives 4i and 4j found significantly active against inflammation. In vitro COX inhibition assay also supported the result in favor of selectivity and efficacy of derivatives. [GRAPHICS] .

Thiazolidine-4-one clubbed pyrazoles hybrids: Potent alpha-amylase and alpha-glucosidase inhibitors with NLO properties

Molecular hybrids based on thiazolidin-4-one and pyrazolyl pharmacophore (THZP) as new antidiabetic agents were synthesized. Two sets of signals came into view in H-1 NMR of THZP8-THZP14 exhibited the presence of a configurational isomeric mixture of 2E,5Z (38.24%-41.58%) and 2Z,5Z isomers (58.42%-61.76%), which was further endorsed by density functional theory (DFT) studies. All the compounds exhibit promising nonlinear optical properties (NLO). Further, the biological potential of THZPs was explored in terms of alpha-amylase and alpha-glucosidase inhibition. DFT-based descriptors were calculated to describe the reactivity, and a relationship was developed with biological activities. THZP9 and THZP14 showed remarkable inhibition of alpha-amylase and alpha-glucosidase with IC50 9.90 mu M and 4.84 mu M, respectively, as compared with standard drug acarbose.
