    Synthesis and Screening of Human Monoamine Oxidase-A Inhibitor Effect of New 2-Pyrazoline and Hydrazone Derivatives
    (Wiley-VCH Verlag GmbH, 2015) Evranos-Aksoz, Begüm; Baysal, İpek; Yabanoğlu-Çiftçi, Samiye; Djikic, Teodora; Yelekçi, Kemal; Uçar, Gülberk; Ertan, Rahmiye; Molecular Biology and Genetics; 05. Faculty of Engineering and Natural Sciences; 01. Kadir Has University
    A group of 35-diaryl-2-pyrazoline and hydrazone derivatives was prepared via the reaction of various chalcones with hydrazide compounds in ethanol. Twenty original compounds were synthesized. Ten of these original compounds have a pyrazoline structure nine of these original compounds have a hydrazone structure and one of these original compounds has a chalcone structure. Structural elucidation of the compounds was performed by IR H-1 NMR C-13 NMR mass spectral data and elemental analyses. These compounds were tested for their inhibitory activities toward the A and B isoforms of human monoamine oxidase (MAO). Except for 3k and 6c all compounds were found to be competitive reversible and selective inhibitors for either one of the isoforms (hMAO-A or MAO-B). Compounds 3k and 6c were found to be competitive reversible but non-selective MAO inhibitors. Compound 6h showed hMAO-B inhibitory activity whereas the others potently inhibited hMAO-A. Compound 5c showed higher selectivity than the standard drug moclobemide. According to the experimental K-i values compounds 6i 6d and 6a exhibited the highest inhibitory activity toward hMAO-A. The AutoDock 4.2 program was employed to perform automated molecular docking. The calculated results obtained computationally were in good agreement with the experimental values.

    Synthesis Anticancer Activity and Molecular Modeling of Etodolac-Thioether Derivatives as Potent Methionine Aminopeptidase (type Ii) Inhibitors
    (Wiley, 2018) Çoruh, Işıl; Çevik, Ozge; Yelekçi, Kemal; Djikic, Teodora; Küçükgüzel, Şükriye Güniz; Molecular Biology and Genetics; 05. Faculty of Engineering and Natural Sciences; 01. Kadir Has University
    A series of (RS)-1-{[5-(substituted)sulfanyl-4-substituted-4H-124-triazole-3-yl]methyl}-18-diethyl-1349-tetrahydropyrano[34-b]indoles (5a-v) were designed and synthesized using a five-step synthetic protocol that involves substituted benzyl chlorides and (RS)-5-[(18-diethyl-1349-tetrahydropyrano[34-b]indole-1-yl)methyl]-4-substituted-24-dihydro-3H-124-triazole-3-thiones in the final step. The synthesized derivatives were evaluated for cytotoxicity and anticancer activity in vitro using the MTT (3-(45-dimethylthiazol-2-yl)-25-diphenyltetrazolium bromide) colorimetric method against VERO HEPG2 (human hepatocellular liver carcinoma) SKOV3 (ovarian carcinoma) MCF7 (human breast adenocarcinoma) PC3 and DU145 (prostate carcinoma) cells at 10(-5)M (10M) for 24h. Compounds 5d and 5h showed the best biological potency against the SKOV3 cancer cell line (IC50=7.22 and 5.10M respectively) and did not display cytotoxicity toward VERO cells compared to etodolac. Compounds 5k 5s and 5v showed the most potent biological activity against the PC3 cancer cell line (IC50=8.18 3.10 and 4.00M respectively) and did not display cytotoxicity. Moreover these compounds were evaluated for caspase-3 -9 and -8 protein expression and activation in the apoptosis pathway for 6 12 and 24h which play a key role in the treatment of cancer. In this study we also investigated the apoptotic mechanism and molecular modeling of compounds 5k and 5v on the methionine aminopeptidase (type II) enzyme active site in order to get insights into the binding mode and energy.

    Synthesis Molecular Modeling in Vivo Study and Anticancer Activity of 124-Triazole Containing Hydrazide-Hydrazones Derived From (s)-Naproxen
    (Wiley-VCH Verlag GmbH, 2019) Han, Muhammed İhsan; Bekçi, Hatice; Uba, Abdullahi İbrahim; Yıldırım, Yeliz; Karasulu, Ercüment; Cumaoğlu, Ahmet; Karasulu, Hatice Y.; Yelekçi, Kemal; Yılmaz, Ozguer; Küçükgüzel, Şükriye Güniz; Molecular Biology and Genetics; 05.

    A new series of 124-triazole containing hydrazide-hydrazones derived from (S)-naproxen (7a-m) was synthesized in this study. The structures of these compounds were characterized by spectral (Fourier-transform infrared spectroscopy H-1-nuclear magnetic resonance (NMR) C-13-NMR and high-resolution electron ionization mass spectrometry) methods. Furthermore molecular modeling of these compounds was studied on human methionine aminopeptidase-2. All synthesized compounds were screened for anticancer activity against three prostate cancer cell lines (PC3 DU-145 and LNCaP) using the 3-(45-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium colorimetric method. Compound 7a showed the best activity against the PC3 DU-145 and LNCaP cancer cell lines with IC50 values of 26.0 34.5 and 48.8 mu M respectively. Compounds 7b 7k and 7m showed anticancer activity against cancer cell lines PC3 and DU-145 with IC50 values of 43.0 36.5 29.3 mu M and 49.8 49.1 31.6 mu M respectively. Compounds 7f and 7g showed anticancer activity against PC3 cells with IC50 values of 43.4 and 34.5 mu M respectively. To assess the biodistribution in mice of IRDye800 dye-labeled compound 7a or 100 mu M of free dye was injected intravenously into the mice's tail. In vivo images were taken with in vivo imaging system spectrum device at 60 120 180 240 300 and 360 min after injection. At the end of 360 min ex vivo studies were carried out to determine in which organs the dye was accumulated in the urogenital system. Ex vivo studies showed that the accumulation of compound 7a in the prostate is greater than that of the free dye and it is concluded that compound 7a may be promising for the treatment of prostate cancer..
