Chemical composition and antimicrobial activity of essential oils from Centaurea appendicigera and Centaurea helenioides
(Taylor & Francis LTD., 2009)
The chemical components and antimicrobial activity of the essential oils from Centaurea appendicigera C. Koch and Centaurea helenioides Boiss, two different endemic members of the genus Centaurea L. (Asteraceae), were ...
Chemical constituents and antimicrobial activities of the essential oils from Sedum pallidum var. bithynicum and S. spurium grown in Turkey
(Taylor&Francis LTD., 2010)
Chemical compositions of the essential oil of Sedum pallidum Bieb. var. bithynicum (Boiss.) and S. spurium Bieb. (Crassulaceae) from Turkey were investigated by GC-MS, and antimicrobial activity of the oil samples were ...
Synthesis of novel symmetrical 1,4-disubstituted 1,2,3-bistriazole derivatives via 'click chemistry' and their biological evaluation
(Mdpi, 2016)
A series of symmetric bis-1,2,3-triazole compounds 2-5(a-f) were synthesized as potential antioxidant agents via click chemistry. Their structures were confirmed by H-1-NMR and C-13-NMR. All of the synthesized compounds ...
Synthesis of some heterofunctionalized penicillanic acid derivatives and investigation of their biological activities
(Wiley-V C H Verlag Gmbh, 2014)
6-Substituted amino-penicillanic acid esters were synthesized starting with 6-apa. the compounds containing a 1,3-thiazole- or 1,3-thiazolidinone nucleus linked to the penicillanic acid skeleton via a hydrazino linkage ...
Synthesis and antimicrobial properties of N-substituted derivatives of (E)-2 ',3 ''-thiazachalcones
(Walter de Gruyter Gmbh, 2015)
N-alkyl substituted 2',3 ''-thiazachalcones {3-[(1E)-3-(4-methylthiophene-2-yl)-3-oxoprop-1-en-1-yl]-1-alkyl (C-5-12,C-14) pyridinium bromides} were synthesized by a two-step reaction. the newly synthesized compounds were ...
Microwave-assisted and conventional synthesis of novel antimicrobial 1,2,4-triazole derivatives containing nalidixic acid skeleton
(Walter de Gruyter Gmbh, 2016)
Carbothioamides 4a,b, obtained from nalidixic acid, were converted to the corresponding 1,3-thiazolidine derivatives 5a,b by cyclocondensation with 2-bromo-1-(4-chlorophenyl) ethanone. Treatment of 4a,b with base afforded ...
Synthesis, and prediction of molecular properties and antimicrobial activity of some acylhydrazones derived from N-(arylsulfonyl)methionine
(Scientific Technical Research Council Turkey-Tubitak, 2016)
A series of 38 new acylhydrazones [3-40], derived from (2S)-4-(methylsulfanyl)-2-[[(4-methylphenyl)sulfonyl] amino]butanoic acid hydrazide [2], were synthesized and evaluated for their anti-HIV and antimicrobial activity ...
Synthesis and antimicrobial, antiproliferative evaluation of novel quinolone and conazole analogues via conventional and microwave techniques
(Wiley, 2021)
1,2,4-Triazole-3-one (3), acquired from cinnamaldehyde was converted to the corresponding carbox(thio)amides via several steps (6 a-c). Their reaction with sodium hydroxide gave the 1,2,4-triazole derivatives (7 a-c). ...
Synthesis and antimicrobial activity of new piperazine-based heterocyclic compounds
(Walter de Gruyter Gmbh, 2017)
The hydrazide 5, that was obtained from -1-(4-fluorophenyl) piperazine (1), was converted to the cor-responding carbothioamides 6a-c by the reaction with alkyl(aryl) isothiocyanates. the synthesis of conazole analogs 10a-f ...
New pyridine derivatives as antiurease inhibitors: Synthesis and their evaluation for antimicrobial activities
