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 Citation - Scopus: 1Synthesis and Biological Evaluation of New 4-Thiazolidinone Derivatives of Flurbiprofen(Acg Publications, 2023) Suzgun, Pelin; Senkardes, Sevil; Gurboga, Merve; Ozakpinar, Ozlem Bingol; Kucukguzel, S. GunizIn this study, the synthesis and characterization of 2-(2-fluorobiphenyl-4-yl)-N '-[(substituted methylene]propanehydrazides (3a-s) and 2-(2-fluoro-[1,1'-biphenyl]-4-yl)-N-(5-methyl-2-(substituted aryl)-4oxothiazolidin-3-yl)propanamides (4a-s) are described and also the antiproliferative effect of the compounds on HT 29, HeLa, A549 and MCF-7 cancer cell lines is investigated. Additionally, mouse embryonic fibroblast cells NIH3T3 were also evaluated to determine the selectivity. The results showed that the identified compounds did not cause any toxicity against NIH3T3 cell line. Moreover, N-(2-(3,5-Bis(trifluoromethyl)phenyl)-5-methyl-4-oxothiazolidin-3-yl)-2-(2-fluoro-[1,1'-biphenyl]-4-yl)propanamide (4h) had the most growth inhibitory effect (55.97% inhibition) on HT-29 colorectal adenocarcinoma cell line. The results obtained from the study show that the compound 4h, which has no cytotoxic effect on normal cells, may be an alternative in the treatment of colon cancer.Article Citation - WoS: 41Citation - Scopus: 39Synthesis and Anticancer Activity of Novel Hydrazone Linkage-Based Aryl Sulfonate Derivatives as Apoptosis Inducers(Springer Birkhauser, 2022) Senkardes, Sevil; Han, M. Ihsan; Gurboga, Merve; Ozakpinar, Ozlem Bingol; Kucukguzel, S. Guniz; Güniz Küçükgüzel, Ş.; İhsan Han, M.In the present study, the various 28 hybrid molecules containing hydrazone and sulfonate moieties were synthesized and characterized by FTIR, H-1-NMR, C-13-NMR spectroscopy and LC-MS spectrometry, besides elemental analysis. The compounds were evaluated for their antiproliferative effects against six cancer cell lines, namely A549 (non-small cell lung cancer), MCF-7 (breast cancer), HT-29 (colorectal adenocarcinoma cancer), PC-3 (androgen-independent prostate adenocarcinoma), Hep3B (hepatocellular carcinoma cancer), and HeLa (epitheloid cervix carcinoma cancer). Among all the target compounds, compounds 4g and 4h exhibited more promising effects on MCF-7 cell lines (IC50 = 17.8 mu M and 21.2 mu M, respectively) with high selectivity. Further mechanistic studies proposed that compounds 4g and 4h induced apoptosis is mediated through the intrinsic apoptotic pathway with changes in mitochondrial membrane potential by finally activating caspase-9 and caspase-3. The results have been encouraging enough to merit further investigation. [GRAPHICS] .
