A number of studies have demonstrated the biological activities of peroxisome proliferator-activated receptors. However, few studies have addressed the effects of the agonists of these receptors on lung diseases. The aim of the present study was to evaluate the anti-inflammatory action of a novel synthetic thiazolidine derivative (5Z)-3-benzyl-5-(1H-indol-3-ylmethylene)-thiazolidine- 2,4-dione (LPSF/RA-4) on acute lung inflammation (pleurisy) induced by carrageenan. Forty mice were randomly allocated to the following groups: (I) saline control group (sham); (II) carrageenan (CAR) group; (III) CAR+LPSF/RA-4 group treated with LPSF/RA-4 (60 μmol/kg); and (IV) INDO group treated with indometacin (5 mg/kg). Total cell counts and the measure of nitric oxide (NO) were performed in pleural exudates. Lung fragments were processed for light microscopy, transmission electron microscopy, immunohistochemistry and Western blotting. The influx of leucocytes and NO levels were significantly reduced following treatment with LPSF/RA-4 and INDO. Histopathological and ultrastructural analyses of the CAR group revealed evident tissue alterations, such as oedema, infiltrates of inflammatory cells and emphysema. These alterations were significantly reduced in the groups treated with LPSF/RA-4 or INDO. Immunohistochemistry revealed an increase in inflammatory markers (COX-2, iNOS, TNF-α and IL-1β) in the lung tissue of the CAR group, whereas the groups treated with LPSF/RA-4 and INDO exhibited significant reductions in such immunomarkers. Western blot analysis revealed an increased expression of COX-2 and IL-1 in the CAR group, which was reduced by treatment with LPSF/RA-4. The present findings demonstrate the potent anti-inflammatory action of the novel derivative thiazolidinedione LPSF/RA-4 in acute lung injury induced by carrageenan.

A series of thiazolidinediones (TZDs) were synthesized and screened for their effect on the mitochondrial respiration as well as on several mitochondrial respiratory system components of Drosophila melanogaster. Substituted and non-substituted 5-benzylidene and 5-benzylthiazolidine-2,4-diones were investigated. The effect of a substitution in position 3, at the nitrogen atom, of the thiozolidine heterocycle was also investigated. The designed TZDs were compared to UK5099, the most potent mitochondrial pyruvate carrier (MPC) inhibitor, in in vitro and in vivo tests. Compared to 5-benzylthiazolidine-2,4-diones 6–7 and 3-benzylthiazolidine-2,4-dione 8, 5-benzylidenethiazolidine-2,4-diones 2–5 showed more inhibitory capacity on mitochondrial respiration. 5-(4-Hydroxybenzylidene)thiazolidine-2,4-dione (3) and 5-(3-hydroxy-4-methoxybenzylidene)thiazolidine-2,4-dione (5) were among the best compounds that compared well with UK5099. Additionally, TZDs 3 and 5, showed no effects on the non-coupled respiration and weak effects on pathways using substrates such as proline, succinate, and G3P. 5-Benzylidenethiazolidine-2,4-dione 3 showed a positive effect on survival and lifespan when added to Drosophila standard and high fat diet. Interestingly, analog 3 completely reversed the effects of high fat diet on Drosophila longevity and induced metabolic changes which suggests an in vivo inhibition of MPC at the mitochondrial level.
Design, synthesis of novel (Z)-2-(3-(4-((3-benzyl-2,4-dioxothiazolidin-5-ylidene)methyl)-1-phenyl-1H-pyrazol-3-yl)phenoxy)-N-arylacetamide derivatives: Evaluation of cytotoxic activity and molecular docking studies

In an attempt to discover potential cytotoxic agents, a series of novel (Z)-2-(3-(4-((3-benzyl-2,4-dioxothiazolidin-5-ylidene)methyl)-1-phenyl-1H-pyrazol-3-yl) phenoxy)-N-arylacetamide derivatives 11a-n were synthesized in varied steps with acceptable reaction procedures with good yields and characterized by 1H NMR, 13C NMR, IR and ESI-MS spectra. All the novel synthesized derivatives were assessed for their cytotoxic activity against human breast cell line (MCF-7) with different concentration of 0.625 μM, 1.25 μM, 2.5 μM, 5 μM and 10 μM respectively. Biological evaluation assay results were displayed in terms of percentage of cell viability reduction and IC50 values. Most of the screened derivatives demonstrated moderate to promising cytotoxic activity. Some of the derivatives, particularly compound 11d and 11n have shown promising cytotoxic activity with IC50 values 0.604 μM and 0.665 μM compared to standard drug cisplatin and compounds 11a, 11e and 11g also have shown considerable cytotoxic activity and the rest of the derivatives have shown moderate activity. Furthermore, molecular docking calculations and ADME properties of the synthesized molecules are in effective compliance with the cytotoxic evaluation results.

A series of fourteen novel thiazolidine-2,4-dione derivatives clubbed with pyrazole moiety were synthesized via four step reaction procedure. Reactions were monitored by thin layer chromatography and were characterized by physicochemical and spectrophotometric (IR, Mass, 1HNMR and 13CNMR) analysis. The spectral data were in good agreement with their structures. The title compounds were docked against peroxisome proliferated activated receptors (PPAR-γ) and alpha-amylase and further evaluated for in vivo and in vitro antidiabetic, in vitro anti-inflammatory and antioxidant activities. Compound GB14 exhibited significant blood glucose lowering activity and was also found to be active inhibitor of alpha-amylase. Compound GB7 was found to be potent anti-inflammatory agent in terms of reducing inflammatory markers (TNF-α, IL-β, MDA) and also showed antioxidant activity to good extent. Therefore, these compounds may be considered as promising candidates for the development of new antidiabetic agents.
