3,6,8-Tribromoquinoline
Celik, Ismail; Akkurt, Mehmet; Okten, Salih; Cakmak, Osman; Garcia-Granda, Santiago (WILEY-BLACKWELL, 2010)The title molecule, C(9)H(4)Br(3)N, is almost planar, the maximum deviation being 0.110 (1) angstrom. The crystal structure is stabilized by weak aromatic pi-pi interactions [centroid-centroid distance = 3.802 (4) angstrom] ... -
6,8-Dibromoquinoline
Celik, Ismail; Akkurt, Mehmet; Cakmak, Osman; Okten, Salih; Garcia-Granda, Santiago (WILEY-BLACKWELL, 2010)The title molecule, C9H5Br2N, is almost planar, with an r.m.s. deviation of 0.027 angstrom. The dihedral angle between the aromatic rings is 1.5 (3)degrees. In the crystal, pi-pi stacking interactions are present between ... -
SAR Evaluation of Disubstituted Tacrine Analogues as Promising Cholinesterase and Carbonic Anhydrase Inhibitors
Okten, Salih; Ekiz, Makbule; Tutar, Ahmet; Butun, Burcu; Kocyigit, Umit Muhammet; Topcu, Gulacti; Gulcin, Ilhami (ASSOC PHARMACEUTICAL TEACHERS INDIA, 2019)Background: The inhibition of both hydrolysis products of acetylcholine (ACh), Acetylcholinesterase (AChE) and Butyrylcholinesterase (BChE), is essential for successful treatment of Alzhemier patients. Objectives: This ... -
Synthesis, characterization, and SAR of arylated indenoquinoline-based cholinesterase and carbonic anhydrase inhibitors
Ekiz, Makbule; Tutar, Ahmet; Okten, Salih; Butun, Burcu; Kocyigit, Umit M.; Taslimi, Parham; Topcu, Guelacti (WILEY-V C H VERLAG GMBH, 2018)We report the synthesis of bromoindenoquinolines (15a-f) by Friedlander reactions in low yields (13-50%) and the conversion of the corresponding phenyl-substituted indenoquinoline derivatives 16-21 in high yields (80-96%) ... -
Synthesis, characterization, crystal structures, theoretical calculations and biological evaluations of novel substituted tacrine derivatives as cholinesterase and carbonic anhydrase enzymes inhibitors
Okten, Salih; Ekiz, Makbule; Kocyigit, Umit Muhammet; Tutar, Ahmet; Celik, Ismail; Akkurt, Mehmet; Gokalp, Faik; Taslimi, Parham; Gulcin, Ilhami (ELSEVIER SCIENCE BV, 2019)The six and seven hydrocycle membered disilylanilino acridine (tacrine) analogues (9-11) were synthesized by one-pot procedures. The structures of novel silyl tacrine derivatives were characterized by NMR spectroscopy, ...
