Metal–Organic Framework MIL-101 as an Efficient Heterogeneous Catalyst for Clean Synthesis of Benzothiazoles and Single Crystal X-Ray Diffraction, Quantum Chemical Studies, Electrochemical Performance, Molecular Docking and DNA Interactions
(John Wiley and Sons Inc, 2025) Akbaş, E.; Ruzgar, A.; Sahin, E.; Levent, A.
Benzothiazoles have emerged as a prominent area of research in recent years due to their broad spectrum of biological activities. These heterocyclic compounds, which contain thiazole and benzene rings in their molecular structure, exhibit a wide range of pharmacological effects, including anticancer, antimicrobial, antifungal, antiparasitic, anti-inflammatory, and antitubercular activities. In this study, benzo[d]thiazole derivatives 1 and 2 were synthesized in good yield using catalyst MIL101. The structures of these compounds were analyzed using elemental analysis, IR, 1H, 13C NMR and single crystal X-ray diffraction. The quantum chemical calculations of ‎these compounds were performed density functional theory method, DGDZVP base set and B3LYP ‎functions with Gaussian09W software package. The electrochemical properties of these compounds were investigated by cyclic voltammetry technique on a glassy carbon electrode. In addition, the interactions of the compounds with DNA were investigated by electrochemical, spectrophotometric and molecular docking techniques. It was observed that the chemical calculations and molecular docking results were compatible with each other. © 2025 Wiley-VCH GmbH.
Protective Effect of Ferulago Angulata (Schlecht.) Boiss on N-Nitrosodimethylamine Induced Oxidative Stress in Rats
(Yuzuncu Yil Universitesi Tip Fakultesi, 2019) Kızıltaş, H.; Ekin, S.; Akkoyun, M.B.; Oto, G.; Akbaş, E.
The aim of the present study was to investigate the effect of Ferulago angulata (Schlecht.) Boiss. (FASB) extract on mineral (Ca, K, Na) and trace element (Cu, Zn, Se, Co, Fe, Mn, Cr, Pb, Ni, Cd) levels were determined in rat heart tissue, which was oxidatively stressed with N-nitrosodimethylamine (NDMA). Experimental period was continued with Wistar-Albino rats (n:60) in 21 days. Rats were treated with NDMA (10 mg/kg) in first seven days. FASB plant extract was given to the rats each day of the study. The rats were divided into six groups of ten rats each. The mineral and trace element levels of heart tissue were analyzed by using ICP-OES. The results show that NDMA group was significantly lower results than control group with regarding to Zn, Co and Na levels (p<0.05, p<0.01 and p<0.05). On the other hand the NDMA group was also significantly lower results than the FASB (300 mg/kg) group regarding Zn and Co levels (p<0.05 and p<0.05), whereas the FASB (150 mg/kg) group had increased level of Na according to NDMA group (p<0.05). In conclusion, due to the positive effect on significantly alteration in Zn and Co level of heart tissue, it was suggested that the FASB (150, 3 00 mg/kg) can be used in preventing hearth damage. © 2019, Yuzuncu Yil Universitesi Tip Fakultesi.

Synthesis and Some Reactions of 4-Benzoyl Pyrazole-3 Acid
(2004) Şener, A.; Akbaş, E.; Şener, M.K.
The 1H-pyrazole-3-carboxylic acid 2, obtained from the furandione 1 and 2-hydrazinopyridine, was decarboxylated to give 4-benzoyl-5-phenyl-1-pyridin-2- yl-pyrazole derivative 3. Some ester 4 derivatives of 2 were prepared by the Fischer esterification reactions of 2 with various alcohols. Cyclocondensation reactions of 2 with phenyl hydrazine or hydrazine hydrate led to the formation of derivatives of pyrazolo[3,4-d]pyridazine 5 derivatives.
