Some nitroimidazole derivatives as possible antibacterial agents
Demirayak, Şeref; Kiraz, N. (1993)In this study, six 1-[2(benzazol-2-yl)thioethy-2-methyl-5-nitroimidazole derivatives were synthesized. Antibacterial activities of the compounds obtained were examined and it was found that they are effective against aerobe ... -
Spectroscopic determination of acid dissociation constants of some biologically active 6-phenyl-4,5-dihydro-3(2H)-pyridazinone derivatives
Öğretir, Cemil; Yarlıgan, S; Demirayak, Şeref (American Chemical Society, 2002)The acid dissociation constants, pK(a), of twelve biologically active 6-phenyl-4,5-dihydro-3(2H)-pyridazinone derivatives were determined using spectroscopic techniques. Elucidation of the structure-reactivity relationships ... -
Synthesis and vasodilatory activity of some thiazolo-triazole derivative
In this study, some thiazolo[3,2-b]-1,2,4-triazole derivatives were synthesized. Their vasodilatory activities were examined in vitro. All examined compounds showed appreciable activity. -
Synthesis of some 2-[(benzazole-2-yl)thioacetyl]phenol derivatives and preliminary investigation on their vasodilatory activity
Turan, Gülhan; Demirayak, Şeref; Erol, Kevser; Özdemir, M. (1994)Some 2-[(benzazol-2-yl)thioacetyl]phenol derivatives were synthesized and their structures were elucidated by IR, NMR and microanalyses. The vasodilatory activity of the obtained compounds was investigated. -
Synthesis of some pyrido- and pyrazino-benzimidazole derivatives and their antifungal activity
Demirayak, Şeref; Güven, Kıymet (1995)Some 2-aryl-4-hydroxypyrido[1,2-a]benzimidazole and 1-substituted 3-arylpyrazino-[1,2-a]benzimidazole derivatives were synthesized using 1-(2-arylethan-2-on)2-acylbenzimidazole derivatives as starting materials. Antifungal ...
