DESIGN,, SYNTHESIS AND PHARMACOLOGICAL EVALUATION OF NEW SUBSTITUTED THIAZOLIDIN-4-ONE DERIVATIVES

4-thiazolidinones are among the most extensively investigated class of organic compounds. Thiazolidin-4-one has been considered as magic moiety, which is a core structure in various synthetic pharmaceuticals displaying a broad spectrum of biological activities. They are widely used as anti-inflammatory, anticonvulsant, analgesic, antimicrobial, anti-HIV, CNS depressant, carcinostatic, antihypertensive and cytotoxic. In view of the wide spectrum activities of condensed 4-thiazolidinones, it was thought worthwhile to undertake the synthesis of heterocyclic systems in which 4-thiazolidinone nucleus is linked to another biologically active moiety. Semicarbazide/Thiosemicarbazide was reacted with benzoyl chloride to obtain N-hydrazinocarbonyl benzene-1-carboxamide/N-hydrazinocarbothioylbenzene-1 carboxamide respectively. These were then condensed with various aldehydes to yield the intermediate Schiff bases. Thiazolidin-4-ones were prepared by the reaction of Schiff bases with mercaptoacetic acid in dry benzene by refluxing for 16-18 hours. The purity of the compounds synthesized was established by TLC. The synthesized derivatives were characterized by FT-IR, (HNMR)-H-1 and Mass spectral analysis. All the derivatives synthesized were screened for their anti-bacterial and antifungal activities using cup-plate method against Bacillus subtilis, Salmonella typhi, Escherichia coli, Staphylococcus aureus, Aspergillus niger and Candida albicans at 100 mu g/ml using ciprofloxacin and clotrimazole as reference standard drugs respectively. The compounds belonging to series (3A1-3A6) have shown promising antibacterial and antifungal activity and those belonging to series (3B1-3B6) were moderate compared to standard. The antimicrobial activity data reveals that, the compounds bearing the phenyl carbonyl urea in their structure, were found to be more potent than the phenyl carbonyl thiourea containing derivatives, indicating the influence of oxygen in enhancing the antimicrobial potency.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 6117-80-2, in my other articles.

Novel 2,3-disubstituted 1,3-thiazolidin-4-one derivatives as potential antitumor agents in renal cell adenocarcinoma

Cancer represents one of the main causes of mortality in developed countries. In particular, the overall survival of patients with renal cell carcinoma (RCC) remains poor and the available cytostatic agents are insufficient. Therefore, there is an urgent requirement to identify more effective and safer anticancer drugs. Recently, the evaluation of antitumor activity appeared to be promising for thiazolidinone derivatives. The present study presents the synthesis and the cytotoxicity assays of 1,3-thiazolidin-4-ones. The newly synthesized substances were screened in vitro against selected cancer human renal cell adenocarcinoma cells (769-P), human hepatoblastoma-derived cells (HepG2) and normal green monkey kidney cells (GMK) as a reference cell line. N-[2-(4-methylphenyl)-4-oxo-1,3-thiazolidin-3-yl]acetamide and N-[2-(4-methylphenyl)-4-oxo-1,3-thiazolidin-3-yl]benzamide displayed significant antiproliferative activity towards 769-P. To elucidate the mechanisms of the cytotoxic actions, additional studies on the cell cycle and apoptosis were performed. The aforementioned compounds were responsible for G1 cell cycle arrest and the decrease in cell distribution in the G2 phase in a dose-dependent manner, which prevents mitotic divisions of the 769-P cells. In addition, these novel 2,3-disubstituted 1,3-thiazolidin-4-ones slightly induced apoptosis in 769-P in a dose-dependent manner. It was hypothesized that the 4-methylphenyl group at position 2 of the thiazolidin-4-one scaffold may be regarded as a promising moiety for further development of this group of compounds. Therefore, benzamide moiety appeared to be crucial for triggering cells to apoptotic cell death.

THE EFFECTS OF NEW 1,3-THIAZOLIDINE-4-ONES WITH PYRRAZOLONE SCAFOLD ON MOTOR FUNCTION IN MICE

The aim of this study was to investigate the effects of new 1,3-thizolidine-4-ones with pyrazolone scaffold (7a-m) on motor function in mice, using RotaRod performance and spontaneous locomotor activity tests. The toxicity screening of these compounds was also performed. The results of RotaRod performance test showed that the compounds don’t have appreciable negative influence on neuromuscular activity, the recorded values being comparable with those of phenazone and control, so it could be appreciated that these compounds don’t have neurotoxic effects. In the case of spontaneous locomotor activity test, the most intense negative effect was observed for 7j (3-OH,4-OCH3), for which the horizontal and vertical movements were lower than phenazone and control at all three-time intervals (1h, 2h, 4h). For other derivatives no appreciable negative effect on spontaneous locomotor activity was observed. Referring to the toxicity degree, all tested compounds showed lower toxicity in reference with phenazone, which supports the favourable influence of 1,3-thiazolidine-4-one moiety on pyrazolone scaffold.

However, highest activity against MCF-7 cell lines was exhibited by Va, Vb, VIk and VIn with IC50 values between 0.040 – 0.050 mu M. All the remaining compounds showed moderate anticancer activity against both the MCF-7 and A549 cell lines.

A series of 21 novel N-1-(2-aryl-1,3-thiazolidin-4-one)-N-3-aryl urea derivatives based on the previously identified lead compound I were synthesized and biologically characterized. The most promising compound 19a was identified as a multi-tyrosine kinase inhibitor, including c-Met, Ron, c-Kit, AXL and IGF-1R, etc. The results of real-time live-cell imaging indicated that compound 19a showed improved cytotoxicity and anti-proliferative activity against HT-29 cancer cells in a time- and dose-dependent manner, with an efficacy that was significantly greater than Cabozantinib. Flow cytometry and western blot analysis demonstrated the fact that anticancer activity was closely related with cancer cell apoptosis and the blockade of the phosphorylation of c-Met and its downstream signaling ERK and Akt. Furthermore, compound 19a also displayed slightly stronger effects on HT-29 cancer cells migration than that of Cabozantinib. (C) 2018 Elsevier Masson SAS. All rights reserved.
