Synthesis molecular modeling in vivo study and anticancer activity of 124-triazole containing hydrazide-hydrazones derived from (S)-naproxen
Han, Muhammed İhsan; Bekçi, Hatice; Uba, Abdullahi İbrahim; Yıldırım, Yeliz; Karasulu, Ercüment; Cumaoğlu, Ahmet; Karasulu, Hatice Y.; Yelekçi, Kemal; Yılmaz, Ozguer; Küçükgüzel, Şükriye Güniz (Wiley-VCH Verlag GmbH, 2019)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 ... -
Synthesis Molecular Modelling and Antibacterial Activity Against Helicobacter pylori of Novel Diflunisal Derivatives as Urease Enzyme Inhibitors
Coşkun, Göknil Pelin; Djikic, Teodora; Kalaycı, Sadık; Yelekçi, Kemal; Şahin, Fikrettin; Küçükgüzel, Şükriye Güniz (Bentham Science Publ Ltd, 2019)Background: The main factor for the prolongation of the ulcer treatment in the gastrointestinal system would be Helicobacter pylori infection which can possibly lead to gastrointestinal cancer. Triple therapy is the treatment ... -
Synthesis of some novel hydrazone and 2-pyrazoline derivatives: Monoamine oxidase inhibitory activities and docking studies
Evranos-Aksoz, Begum; Yabanoglu-Ciftci, Samiye; Ucar, Gulberk; Yelekçi, Kemal; Ertan, Rahmiye (Pergamon-Elsevier Science Ltd, 2014)A novel series of 2-pyrazoline and hydrazone derivatives were synthesized and investigated for their human monoamine oxidase (hMAO) inhibitory activity. All compounds inhibited the hMAO isoforms (MAO-A or MAO-B) competitively ... -
Synthesis, Anticancer Activity on Prostate Cancer Cell Lines and Molecular Modeling Studies of Flurbiprofen-Thioether Derivatives as Potential Target of MetAP (Type II)
Yılmaz, Özgür; Bayer, Burak; Bekçi, Hatice; Uba, Abdullahi, I; Cumaoğlu, Ahmet; Yelekçi, Kemal; Küçükgüzel, S. Guniz (Bentham Science PUBL LTD, 2020)Background: Prostate cancer is still one of the serious causes of mortality and morbidity in men. Despite recent advances in anticancer therapy, there is a still need of novel agents with more efficacy and specificity in ... -
Synthesis, in silico studies and cytotoxicity evaluation of novel 1,3,4-oxadiazole derivatives designed as potential mPGES-1 inhibitors
Erensoy, Gizem; Ding, Kai; Zhan, Chang-Guo; Elmezayen, Ammar D.; Yelekçi, Kemal; Duracık, Merve; Özakpınar, Özlem Bingol; Küçükgüzel, İlkay (MARMARA UNIV, 2020)A series of new 1,3,4-oxadizole derivatives containing thioether group, has been synthesized to investigate their mPGES-1 inhibitory activities. The synthesized compounds were also evaluated for their anticancer and COX-1/2 ... -
