Abu Mohsen, Usama; Koçyiğit-Kaymakçıoğlu, Bedia; Oruç-Emre, Emine Elçin; Kaplancıklı, Zafer Asım; Rollas, Sevim (Aves Press LTD, 2015)Objective: Fifteen hidrazide-hydrazone derivatives were synthesized and evaluated for their ability to inhibit acetylcholinesterase (AChE) using a modification of Ellman's spectrophotometric method. Methods: Anti-acetylc ... -
Synthesis and biological activity of hydrazide-hydrazones and their corresponding 3-acetyl-2,5-disubstituted-2,3-dihydro-1,3,4-oxadiazoles
Koçyiğit-Kaymakçıoğlu, Bedia; Oruç-Emre, Emine Elçin; Ünsalan, Seda; Tabanca, Nurhayat; Khan, Shabana I.; Wedge, David Earl; Rollas, Sevim (Springer Birkhauser, 2012)Various 3-acetyl-2,5-disubstituted-2,3-dihydro-1,3,4-oxadiazoles (11-20) were prepared by the reaction of aryl substituted hydrazones of 4-fluorobenzoic acid hydrazide (1-10) with acetic anhydride. The structures of the ... -
The synthesis and evaluation of anti-acetylcholinesterase activity of some 4(3H)-quinazolinone derivatives bearing substituted 1,3,4- thiadiazole
Uraz, Mine; Karakus, Sevgi; Abu Mohsen, Usama; Kaplancıklı, Zafer Asım; Rollas, Sevim (Marmara University, Fac Medicine, 2017)In the present study, a series of 4(3H)-quinazolinone derivatives (5a-f) were synthesized through the cylization reaction of substituted 1,3,4-thiadiazoles containing an aromatic primary amin and anthranilic acid in the ...
