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.

Synthesis and Evaluation of Anticonvulsant Activities of 5-Benzylidene-2-(5-methylisoxazol-3-ylimino)thiazolidin-4-one Derivatives

Fifteen new 5-benzylidene-2-(5-methylisoxazol-3-ylimino)thiazolidin-4-one derivatives (4-18) were synthesized and evaluated for their preliminary anticonvulsant activity and neurotoxicity by using the maximal electroshock (MES) and rotarod tests. The structures of synthesized compounds were established by IR, H-1 NMR, C-13 NMR and mass spectral data. Among the compounds studied, 5-(3-fluorobenzylidene)-2-(5-methylisoxazol-3-ylimino)thiazolidin-4-one (8) was the most potent compound, with a median effective dose of 43.9 mg/kg and a high protective index (PI) of more than 11.1 after intraperitoneal administration in mice. Compound 8 showed significant oral activity against MES-induced seizures in mice, with an ED50 of 84.2 mg/kg and a PI above 11.8. These results demonstrate that compound 8 is safer than the commercially drugs.

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.

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.

Thioureas and their cyclized derivatives: Synthesis, conformational analysis and antimicrobial evaluation

Several single enantiomer thioureas have been synthesized and have been converted to their cyclic derivatives: 2-imino-thiazolidin-4-ones. The conformations of the thioureas have been determined in solution and in the solid state. In solution; an interconversion between the E,Z and Z,E conformations has been observed with Delta G(not equal) values of around 50 kJ/mol whereas in the solid state they were shown to possess a Z,Z conformation. The thiazolidin-4-ones have been found to be present only in the anti-conformation. All compounds were screened for antimicrobial activity against 4 bacteria. For three of the compounds with the highest antimicrobial activity, the antimicrobial evaluation was expanded using more reference strains and clinical isolates. Among the compounds studied the 5-benzylidene-thiazo-lidine-4-ones 15RR, 15SS and the thiourea 5RR carrying a benzylpyrrolidine scaffold showed better antibacterial activities than the others. The fungicidal activities of all compounds were found to be better than those of the bactericidal activities. (C) 2018 Elsevier B.V. All rights reserved.

Novel 1,3,5-triazine derivatives exert potent anti-cervical cancer effects by modulating Bax, Bcl2 and Caspases expression

This study aimed to develop novel 1,3,5-triazine derivatives as potent anti-cervical cancer agents. The compounds were synthesized in short steps with an excellent yield and characterized via various spectroscopic and analytical methods. A structure-activity relationship study suggested that electron-withdrawing substituents showed greater anticancer activity than electron-donating groups. Compound 7p (p-fluoro) showed the highest activity against cervical cancer cells. In a nude mouse xenograft model inoculated with HeLa cells, 7p showed dose-dependent inhibition of cervical tumour growth. Histopathological examination of excised tumour-bearing tissues showed that 7p improved the microstructure in a dose-dependent manner. Compound 7p also increased the proportions of HeLa cells in G0/G1 and S-phase and significantly decreased that of G2/M-phase. The effects of 7p on C-caspase-3, C-caspase-9, Bcl-2 and Bax expression in HeLa cells were also determined.
