Effect of microwave irradiation on the synthesis of 1,2,4-triazol-3-one derivatives and their antimicrobial activities
(Science Reviews 2000 Ltd, 2012)
An easy efficient method for the synthesis of N-(3,5-dichlorophenyl)-5-alkyl/aryl-3H-1,2,4-triazol-3-one derivatives under microwave irradiation has been developed using the reaction of 3,5-dichloroaniline and ethoxycarb ...
Synthesis, antibacterial and antioxidant activities of new 1-alkyl-4-(1-alkyl-4-oxo-1,4-dihydroquinolin-2-yl)pyridinium bromides
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2013)
New 1-alkyl-4-(1-alkyl-4-oxo-1,4-dihydroquinolin-2-yl)pyridinium bromides (3a k) were synthesized from 1,4'-diazaflavone [2-pyridin-4-ylquinolin-4(1H)-one] and evaluated for antibacterial and antioxidant activities. A rapid ...
Synthesis, aggregation and spectroscopic studies of novel water soluble metal free, zinc, copper and magnesium phthalocyanines and investigation of their anti-bacterial properties
(Pergamon-Elsevier Science Ltd, 2014)
In this study, novel phthalonitrile derivative (3) was synthesized by the reaction between 4-nitrophthalonitrile (2) and a triazole derivative (1) containing pyridine moiety. Crystal structure of compound (3) was characterized ...
Microwave-assisted preparation of azachalcones and their N-alkyl derivatives with antimicrobial activities
(Taylor & Francis Ltd, 2014)
Two new azachalcones were prepared by both Claisen-Schmidt condensation and a simple environmentally trendy microwave-assisted method. Ten new N-alkyl (C-6,C-8,C-10,C-12,C-14)-substituted azachalconium bromides (3a-e, 4a-e) ...
Microwave assisted synthesis of some novel 2-(3-Chlorobenzyl)-1H-benzimidazole derivatives and determination of their antimicrobial activity and pKa values
(Chiminform Data S A, 2015)
In the present research, synthesis of new 2-(3-chlorobenzyl)-1H-benzimidazole derivatives bearing N-benzylidene, 1,2,4-triazole and N-acylhydrazone moiety is investigated. These novel compounds have been tested for their ...

(Bentham Science Publ Ltd, 2015)
2-(2-Chlorobenzyl)-1H-benzimidazole (2) was prepared from the reaction of o-phenylenediamine and ethylimido-o-chlorophenylacetate hydrochloride (1) under microwave irradiation. the acetate and hydrazide derivatives of 2(2- ...
Distribution of beta-lactamase genes among carbapenem-resistant klebsiella pneumoniae strains isolated from patients in Turkey
(Korean Soc Laboratory Medicine, 2015)
Background: the emergence of carbapenem-resistant Klebsiella pneumoniae poses a serious problem to antibiotic management. We investigated the beta-lactamases in a group of carbapenem-resistant K. pneumoniae clinical isolates ...
Investigation of the frequency and distribution of beta-lactamase genes in the clinical isolates of acinetobacter baumannii collected from different regions of Turkey: a multicenter study
(Ankara Microbiology Soc, 2016)
The diversity and distribution of TEM, SHV and CTX-M type of extended-spectrum beta-lactamases (ESBLs) are important for the treatment and control of infections. Determination of ESBL genes in clinical isolates by polymerase ...
A Novel integron gene cassette harboring VIM-38 Metallo-beta-lactamase in a clinical pseudomonas aeruginosa isolate
(Korean Soc Laboratory Medicine, 2016)
Dear Editor,
Multidrug resistance of Pseudomonas aeruginosa has been attributed to both intrinsic and acquired antibiotic-resistance mechanisms. Multidrug-resistant (MDR) P. aeruginosa isolates have become a serious ...
