Determination and evaluation of acidity constants of some imidazole and thiazole linked acetamide compounds
Tay, Naime Funda; Duran, Murat; İspir, Cihan; Demirayak, Şeref (Anadolu University, 2016)In this work, the effect of substituents on the acidity constants of some acetamide derivatives was investigated. The acidity constants of nine acetamide derivatives were determined at 25 °C using a UV spectrophotometric ... -
Discovery of novel potent human chondrosarcoma (SW1353) inhibitors: 4-(2/3/4-pyridyl)thiazole 2-acetamide derivatives
Coşkun, Göknil Pelin; Şahin, Zafer; Erdoğan, Ömer; Çevik, Özge; Biltekin, Sevde Nur; Yurttaş, Leyla; Berk, Barkın; Ülgen, Mert; Demirayak, Şeref (Elsevier B.V., 2023)Chondrosarcoma is the most common cartilage sarcoma among adult patients. It is mainly observed after the degradation of chondrocytes in the case of cell stress. Unfortunately, the mortality among patients is high as a ... -
Novel benzofurane carbonyl analogs of donepezil as acetylcholinesterase inhibitors
Şahin, Zafer; Biltekin, Sevde Nur; Yurttaş, Leyla; Berk, Barkın; Küçükkılınç, Tuba Tüylü; Demirayak, Şeref (Elsevier B.V., 2022)Donepezil is the most prescribed drug for mild to moderate Alzheimer's Disease. There is not any alternative drug with this potency yet. New scaffolds bearing benzofurans and amines are being tested for good potency on ... -
