Article 1,2,4-Triazole Conjugates as HEGFR Inhibitors: Synthesis, Anticancer Evaluation, and in Silico Studies(Wiley-V C H Verlag GmbH, 2026) Bulbul, Bahadir; Kulabas, Necla; Gurboga, Merve; Ozakpinar, Ozlem Bingol; Cakmak, Ummuhan; Tuncay, Fulya Oz; Kucukguzel, IlkayA series of novel 1,2,4-triazole-acetamide derivatives was synthesized and evaluated for anticancer and hEGFR inhibitory activity. The compounds were obtained via multistep synthesis and characterized by spectroscopic methods. Cytotoxicity was tested against PC-3, MCF-7, A549, and K562 cell lines. Compounds <bold>18</bold>, <bold>19</bold>, and especially <bold>24</bold> showed notable antiproliferative effects, with compound <bold>24</bold> exhibiting higher selectivity and potency than gefitinib. It also induced apoptosis and inhibited migration in A549 and PC-3 cells, while selectively promoting invasion in PC-3, suggesting EMT-related behavior. In vitro kinase assays revealed compound <bold>20</bold> as the most potent hEGFR inhibitor (IC50 = 43.8 +/- 1.3 nM). Molecular docking and 200 ns molecular dynamics simulations confirmed its stable interaction with EGFR, particularly involving Cys797. These findings highlight compounds <bold>20</bold> and <bold>24</bold> as promising candidates for further development as EGFR-targeted anticancer agents.Article Synthesis, Molecular Modeling, Anti-Cancer and COX-1/2 Inhibitory Activities of Novel Thiazolidinones Containing Benzothiazole Core(Bangladesh Pharmacological Soc, 2025) Kulabas, Necla; Guven, Cansu Tamniku; Duracik, Merve; Ozakpinar, Ozlem Bingol; Kucukguzel, IlkayIn 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 mu M. 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.Article Bangladesh Journal of Pharmacology(Bangladesh Pharmacological Soc, 2024) Kulabas, Necla; Guven, Cansu Tamniku; Duracik, Merve; Ozakpinar, Ozlem Bingol; Kucukguzel, Ilkay[No Abstract Available]
