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 - WoS: 6Citation - Scopus: 6Synthesis, Antimicrobial Properties and <i>in Silico</I> Studies of Aryloxyacetic Acid Derivatives With Hydrazone or Thiazolidine-4 Scaffold(Taylor & Francis inc, 2023) Senkardes, Sevil; Kart, Didem; Bebek, Bilge; Gunduz, Miyase Gozde; Kucukguzel, S. GunizIn this work, twenty hydrazide-hydrazone and 4-thiazolidinone derivatives were synthesized starting from m-cresol. Antimicrobial evaluation was carried out by microdilution method against Enterococcus faecalis and Staphylococcus aureus as Gram-positive bacteria and Escherichia coli and Pseudomonas aeruginosa as Gram-negative bacteria, and three pathogenic fungi Candida albicans, Candida parapsilosis and Candida krusei. Some compounds possessed considerable antimicrobial properties against the tested microorganisms, particularly against E. coli. 4-Thiazolidinones containing 3-methoxyphenyl and 3,5-dichlorophenyl moieties (4h and 4i) were found to be the most active derivatives with MICs of 2 mu g/mL against E. coli. N'-[(3,5-dichlorophenyl)methylidene]-2-(3-methylphenoxy)acetohydrazide (3i) also displayed antifungal activity against Candida krusei that was comparable to fluconazole. Calculated drug-likeness and ADMET parameters of the most active compounds confirmed their potential as antimicrobial drug candidates. Molecular docking investigations were carried out in the thiamine diphosphate-binding site of pyruvate dehydrogenase multienzyme complex E1 component (PDHc-E1) to clarify the potential antibacterial mechanism against E. coli. The results showed the potential and importance of developing new hydrazones and 4-thiazolidinones that would be effective against microbial strains. Communicated by Ramaswamy H. SarmaArticle 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.
