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 ...
Antimicrobial and antiurease activities of newly synthesized morpholine derivatives containing an azole nucleus
(Birkhauser Boston, 2013)
2-[6-(Morpholin-4-yl)pyridin-3-ylamino]acetohydrazide (4) was obtained starting from 6-morpholin-4-ylpyridin-3-amine (2) via the formation of ester (3) and then converted to the corresponding Schiff bases (5, 6) with the ...
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 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 ...
