Could Peganum harmala be effective in the treatment of COVID-19?
Tüzün, Burak; Nasibova, T; Garaev, E; Sayın, Koray; Ataseven, Hilmi (2021)BACKGROUND: Predominant molecules in Peganum harmala leaves were detected using gas chromatography-mass spectrometry (GC-MS). Based on the results of this analysis, most alkaloids, fl avonoids and triterpenoids in found ... -
Determination of inhibitor activity of drugs against the COVID-19
BACKGROUND: It is the SARS-CoV-2 virus, one of the most signifi cant diseases of today’s world. Due to the high transmission of this disease, studies are ongoing to discover an inhibitor drug that can stop this disease. In ... -
Experimental and Computational Investigation for (E)-2-hydroxy-5-(2- benzylidene) Aminobenzoic Acid Schiff Base as a Corrosion Inhibitor for Copper in Acidic Media
The corrosion behavior of copper in 1 M HCl in the absence and presence of Hha ((E)-2-hydroxy-5-(2-benzylidene) aminobenzoic acid) has been investigated experimentally and computationally. In this way, the electrochemical ... -
Experimental and in silico studies of dichloro- tetrakis (1H-pyrazole)-cobalt(II): Structural description, photoluminescent behavior and molecular docking
Direm, Amani; El Bali, Brahim; Sayın, Koray; Abdelbaky, Mohammed S.M.; García-Granda, Santiago (2021)A novel pyrazole-based Co(II) complex, namely dichloro-tetrakis(1H-pyrazole)-cobalt(II), was synthesized and characterized. Its X-ray crystal structure showed that it crystallizes in the monoclinic C 2/ c space group ... -
Experimental and theoretical investigation of inhibition behavior of 2-((4-(dimethylamino)benzylidene)amino)benzenethiol for carbon steel in HCl solution
Keleş, Hülya; Keleş, Mustafa; Sayın, Koray (2021)2-((4-(dimethylamino) benzylidene)amino)benzenethiol (DBB) compound has been synthesized and tested for prevention of carbon steel corrosion in HCl at different temperatures. The research was carried out using ... -
Investigations of structural, spectral (IR, 1H‑, 9F‑, 11B‑, 13C‑, 15 N‑, 17O‑NMR) and anticancer properties of 5FU@B12N12 complexes
Aktaş, Ahmet; Nassif, Wassim; Sayın, Koray (2021)B12N12 nanocage was selected as a drug carrier for 5-fluorouracil (5FU). Both compounds were optimized B3LYP/6– 31 + G(d) level in the water. Electrophilic/nucleophilic attack regions and the appropriate interaction sites ... -
Investigations substituent effect on structural, spectral and optical properties of phenylboronic acids
Çöpçü, Burcu; Sayın, Koray; Karakaş, Duran (2021)Ortho- and para-substituent arylboronic acid are investigated. Geometric structure and structural proper- ties of these compounds are done. IR and NMR spectrum are calculated for the spectral characterizations. Contour ... -
New anti-viral drugs for the treatment of COVID-19 instead of favipiravir
The SARS-CoV-2 virus is a major problem in the world right now. Currently, all the attention of research centers and governments globally are focused on the investigation of vaccination studies and the discovery of small ... -
Scale factor database for the vibration frequencies calculated in M06-2X, one of the DFT methods
Vibrational scale factors were determined for the M06-2X method. The calculated scale factors were supported statistically. The main objective is to determine the concordance between frequencies. Descriptive statistics ... -
Synthesis and competitive 7 Li NMR studies of two morpholine-based ligands
Rezaeivala, Majid; Zebarjadian, Mohammad Hasan; Sayın, Koray (Elsevier, 2021)7 Li NMR spectroscopy was used to investigation the stability, stoichiometry and thermodynamic infor- mation of a Li + complex with one known, N1-(2-morpholinoethyl)-N1-((pyridine-2-yl)methyl)propane- 1,3-diamine (A 1 ) ... -
