Article Citation - WoS: 7Citation - Scopus: 5Synthesis and Evaluation of Novel Metacetamol Derivatives With Hydrazone Moiety as Anticancer and Antimicrobial Agents(Wiley-v C H verlag Gmbh, 2023) Senkardes, Sevil; Atlihan, Irem; Cayir, Elif; Tiber, Pinar Mega; Orun, Oya; Nigiz, Seyma; Kucukguzel, S. Guniz; Mega Tiber, PınarBy exploiting the wide biological potential of the hydrazone scaffold, a series of hydrazone derivatives were synthesized, starting from N-(3-hydroxyphenyl)acetamide (metacetamol). The structures of the compounds were determined using IR, H-1 and C-13-NMR, and mass spectroscopic methods. The obtained molecules (3 a-j) were evaluated for their anticancer potential against MDA-MB-231 and MCF-7 breast cancer cell lines. According to the CCK-8 assay, all tested compounds showed moderate to potent anticancer activity. Among them, N-(3-(2-(2-(4-nitrobenzylidene)hydrazinyl)-2-oxoethoxy)phenyl)acetamide (3 e) was found to be the most effective derivative with an IC50 value of 9.89 & mu;M against MDA-MB-231 cell lines. This compound was further tested for its potential effects on the apoptotic pathway. Molecular docking studies was also carried out for 3 e in the colchicine binding pocket of tubulin. Additionally, compound 3 e also demonstrated effective antifungal activity, particularly against Candida krusei (MIC=8 & mu;g/ml), indicating that nitro group at the 4(th) position of the phenyl ring was the most preferable substituent for both cytotoxic and antimicrobial activity. Our preliminary findings suggest that compound 3 e could be exploited as a leading structure for further anticancer and antifungal drug development.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: 11Citation - Scopus: 11Synthesis and Biological Evaluation of Novel Aryloxyacetic Acid Hydrazide Derivatives as Anticancer Agents(Taylor & Francis inc, 2021) Senkardes, Sevil; Erdogan, Omer; Cevik, Ozge; Kucukguzel, S. GunizIn our continuing search for new anticancer agents, herein we report the synthesis of 2-(4-chloro-3-methylphenoxy)-N'-[(aryl)methylidene]acetohydrazides 3a-j and the evaluation of their anticancer activities on cell viability, morphological changes and caspase-3 activity in cancer cell lines including gastric cancer (MKN45), cervical cancer (HeLa) and breast cancer (MDA-MB-231) cells. 2-(4-chloro-3-methylphenoxy)-N'-[(4-phenylthiophen-2-yl)methylidene] acetohydrazide 3g presented the strongest growth inhibition against MKN45 gastric cancer cell lines with the IC50 value of 1.471 +/- 0.23 mu M. Moreover, compounds 3b and 3g showed high potency against the HeLa and MDA-MB-231 cell lines having IC50 in the range of 2.38-9.72 mu M. These compounds are more selective for the tested human cancer cells than for the mouse fibroblast cell line (NIH/3T3). As a result of the studies conducted in order to understand the molecular mechanism, compounds 3b and 3g enhanced expression of the caspase-3 pro-apoptotic proteins levels besides caspase-3 gene.Article Citation - WoS: 1Citation - Scopus: 1Synthesis, Molecular Docking Studies and Adme Prediction of Some New Albendazole Derivatives as Α-Glucosidase Inhibitors(Slovensko Kemijsko Drustvo, 2022) Senkardes, Sevil; Kulabas, Necla; Kucukguzel, S. GunizA series of novel 2-(substituted arylidene)-N-(5-(propylthio)-2,3-dihydro-1H-benzo[d]imidazol-2-yl)hydrazine-1-carboxamide derivatives 3a-i were synthesized via condensation of N-(5-(propylthio)-1H-benzo[d]imidazol-2-yl) hydrazinecarboxamide (2), with the corresponding ketone or aldehydes. The chemical structures of the compounds prepared were confirmed by analytical and spectral data. The compounds were screened for their a-glucosidase inhibitory activity and all of them showed better inhibition than acarbose, except 3h. In particular, compound 3a proved to be the most active compound among all synthetic derivatives having IC50 value 12.88 +/- 0.98 mu M. Also, molecular docking studies were carried out for the compounds to figure out the binding interactions. Compound 3a has exhibited the highest binding energy (Delta G = -9.4 kcal/mol) and the most hydrogen bond interactions with active sites. Eventually, in silico studies were in good agreement with in vitro studies.
