Reduction, Mannich reaction, and antimicrobial activity evaluation of some new 1,2,4-triazol-3-one derivatives
(TÜBİTAK, 2012)
Ethyl[4-arylmethyleneamino-3-(4-metylphenyl)-5-oxo-4,5-dihydro-1H -1,2,4-triazole-1-yl]acetates (3a-e and 10a-d) were obtained starting from 4-amino-2,4-dihydro-3H -1,2,4-triazol-3-ones (1 and 9) in 2 steps. The treatment ...
Antimicrobial activity and a comparative essential oil analysis of Centaurea pulcherrima Willd. var. pulcherrima extracted by hydrodistillation and microwave distillation
(Taylor & Francis Online, 2012)
The essential oils of Centaurea pulcherrima Willd. var. pulcherrima (Asteraceae) were isolated by hydrodistillation (HD) and a microwave distillation (MD), than characterised by GC-FID and GC-MS. A total of 58 and 57 ...
Chemical constituents and antimicrobial activity of the essential oil from vicia dadianorum extracted by hydro and microwave distillations
(2012)
The aim of this research was to investigate the influence of extraction methods on yield and chemical composition of the essential oil of Vicia dadianorum Somm. & Lev. The volatiles of V. dadianorum have been isolated by ...
Design and synthesis of new 1,2,4-triazole deriaties containing morpholine moiety as antimicrobial agents
(TÜBİTAK, 2012)
2-Morpholine-4ylethyl-3H -1,2,4-triazole-3-ones (2a, 2b) were obtained from the condensation between the corresponding ethoxycarbonylhydrazones and 2-morpholinoethanamine. 2a was conerted to acetohydrazide (4) ia the ...

Synthesis of eperezolid-like molecules and evaluation of their antimicrobial activities
(Springer Link, 2012)
3-Fluoro-4-(4-phenylpiperazin-l-yl)aniline (II) prepared from 3,4-difluoro nitrobenzene was converted to the corresponding Schiff bases (III) and (IV) by treatment with 4-methoxybenzaldehyde and indol-3-carbaldehyde, ...
Preparation and antimicrobial activity evaluation of some quinoline derivatives containing an azole nucleus
(2012)
Quinoline-2-carbohydrazide (2) obtained from quinaldic acid (1) was converted to the corresponding carbothioamide 3 and carboxamide 6 by treatment with benzyliso(thio)cyanate. The basic treatment of 3 and 6 yielded the ...
Purification and characterization of an extracellular lipase from Mucor hiemalis f. corticola isolated from soil
(Elsevier, 2012)
We have screened 39 microfungi isolates originated from soil in terms of lipolytic activity. Out of all screened, a novel strain of Mucor hiemalis f. corticola was determined to have the highest lipase activity. The ...
Design and synthesis of some azole derivatives as potential antimicrobial agents
(Birkhauser Boston, 2012)
Syntheses of 1,2,4-triazol-3-ones, 4a, 4b, and 5 were performed starting from ester ethoxycarbonylhyd-razones (1a, 1b) that were reported earlier. The treatment of triazole derivatives, 4a, 4b, and 5 with several sulfonyl ...
