Synthesis and antimicrobial activities of novel bisacridine-1,8-dione derivatives
(SPRINGER BIRKHAUSER, 2011) Kaya, Muharrem; Yildirir, Yilmaz; Celik, Gokcen Y.
A series of bisacridine-1,8-dione derivatives were synthesized by one-pot reaction of aromatic dialdehydes, dimedone or cyclohexane-1,3-dione and primer aromatic amines in acetonitrile to utilizing Amberlyst-15 as a heterogeneous catalyst. The structures of compounds were characterized by FT-IR, NMR, and elemental analysis. Antimicrobial activities of these compounds were determined by using the disc diffusion method against to these gram-positive and gram-negative bacteria and yeast. The results were compared with reference discs.
Synthesis, electrochemical, and antibacterial activity of some novel N(4)O(2) ligand derivativies
(MAIK NAUKA/INTERPERIODICA/SPRINGER, 2008) Demir, Ibrahim; Sahmetlioglu, Ertugrul; Celik, Gokcen Y.; Unal, Murat
A novel ligand has been synthesized by the condensation of 1,3-diaminoprophane (HL) with isonitroso-p-chloroacetophenone. The complexes of cobalt(II), nicel(II), cupper(II) and zinc(II) with HL were prepared. All compounds were characterized by spectroscopic techniques and its antibacterial activities were determined by the disc diffusion method used against to those gram-positive and-negative bacteria. All compounds were investigated by cyclic voltammetry at 25 degrees C. The voltammograms were recorded with a potential scan of 100 mV s(-1).
