    A New Candidate for the Treatment of Alzheimer's Disease; Synthesis, Characterization, Investigation of Drug Properties with In Silico Methods
    (2025) Tilki, Tahir; Yeşil, Tolga Acar; Dilek, Ömer
    Brain disorder-caused mortality has emerged as the second of all diseases worldwide in the 21st century. Alzheimer’s Disease (AD) is the most common disease that takes place among brain disorders according to statistics. Therefore, in this study, potential new drug candidate for AD (2-amino-N'-benzylidene-4-(trifluoromethyl)benzohydrazide, ABTH) was synthesized, starting from -CF3 and -NO2 containing carboxylic acid. The structure of ABTH was elucidated using 1H, 13C-APT NMR, FTIR, and Mass analyses. ADMEt properties were calculated and from the ADMEt results, it was observed that the ABTH crossed the Blood-Brain Barrier (BBB), the most important property in evaluating new drug candidate in brain disorders. Molecular Docking studies were conducted using proteins related AD. According to docking studies, 2OI0-ABTH was the highest docking score with the -8.9 kcal/mol. Standard drugs (Donepezil, Galantamine, Rivastigmine) used in AD treatment were also docked with the AD proteins to do meaningful comparison. The molecular docking results showed that the ABTH has higher docking score than standards. Since 2OI0-ABTH complex had the best docking score, it was chosen for the MD simulation studies. From the obtained results, It can be suggested that ABTH promising drug candidate for AD after further investigations were done

    Imidazole and Quinoline-Based Promising Agent for Cancer Treatment; Synthesis, Characterization, and Computational Calculations
    (2024) Yeşil, Tolga Acar; Dilek, Ömer; Tilki, Tahir
    In this study, a novel imidazole and quinoline-based azo compound (MITPDQ) was synthesized, starting from aniline derivative which was used as an intermediate to synthesize nilotinib, which was used in leukemia treatment, characterized, and its structure was elucidated with spectroscopic techniques such as NMR, FTIR, UV, FTIR, and MS. Theoretical calculations using DFT (B3LYP) method and 6-311G (d,p) basis set were done to obtain optimized geometry and spectral data of MITPDQ. Experimental results were compared with theoretical ones and it was observed that they were compatible with each other. Using the optimized geometry of MITPDQ, the molecular docking studies were also conducted with cancer-related proteins. From docking results, the highest docking score was found to be -11.0 kcal/mol between MITPDQ and 2XIR protein. Also, the ADMET properties of MITPDQ were calculated. From ADMET and docking studies, it was concluded that the MITPDQ has the potential to be a drug candidate after further investigations were done related with this field.
