    In this study, new 1,3-thiazolidin-4-one derivatives containing arylmethylene groups in the 5-position were obtained from 6-(trifluoromethoxy)-1,3-benzo-thiazol-2-amine (riluzole). Synthesized compounds were characterized by spectral data and elemental analysis. In vitro, cytotoxic activities of the synthesized molecules were evaluated against the human lung cancer (A549) and human prostate cancer (PC-3) cell lines. Compounds were also tested on mouse embryonic fibroblast cells (NIH/3T3) to determine selectivity. Ten target compounds 3-12 were also screened for their COX-1 and COX-2 inhibitory activities. Of these compounds, 4 showed the highest COX-2 inhibition at 10 μM. Molecular docking calculations were performed to understand the binding interactions of compounds with COX-1 and COX-2 proteins. In silico studies of the tested compounds represented important binding modes that may be responsible for their anti-cancer activity via selective inhibition of the COX-2 enzyme. ADMET predictions were conducted to assess the drug-like properties of the novel compounds. © 2024 Elsevier B.V., All rights reserved.

    Objective: The aim of this study was to evaluate the ameliorative effects of swimming training on renal and bladder damage caused by a highfat diet (HFD) using morphological and biochemical measurements. Methods: Sprague Dawley rats were fed either standard chow (CONT, 6% fat) or HFD (45% fat) for 18 weeks, these rats were divided into two subgroups at the last 6 weeks of the experiment. The exercise groups (CONT+EXC, HFD+EXC) were trained daily swimming sessions (1 h per day for 5 days/week) during the last 6 weeks. Kidney and bladder samples were prepared for light and electron microscopic examination at the end of experiment. Malondialdehyde, glutathione, interleukin-6, and tumor necrosis factor-a were measured by biochemically. Results: Regular morphology of the renal cortex and bladder mucosa was observed in the CONT and CONT +EXC groups. Degenerated renal corpuscles and proximal tubules in the kidney and degenerated urothelium with leaky tight junctions and mast cell increase in the bladder mucosa were observed in the HFD group. Ameliorated renal cortex and bladder mucosa were observed in the HFD+EXC group. In addition, malondialdehyde, glutathione, interleukin-6, and tumor necrosis factor-a levels were also consistent with the histological findings. Conclusion: HFD-induced renal and bladder damage may be related to increased oxidative damage. It was observed that the histological damage and altered oxidative stress parameters could be reversed by swimming training, and it is thought that moderate swimming exercise may play a role in regulating oxidative stress.
