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 ...
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 ...
Antimicrobial activity and analyses of six Geranium L. species with headspace SPME and hydrodistillation
(Taylor & Francis Ltd, 2016)
A solid phase microextraction (SPME) method with gas chromatography-mass spectrometry (GC-MS) was used for analyses of the volatile compounds of six Geranium species; G. asphodeloides, G. psilostemon, G. purpureum, G. ...
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 ...
Microwave assisted synthesis and antimicrobial activity evaluation of new heterofunctionalized norfloxacine derivatives
(Bentham Science Publ Ltd, 2016)
The synthesis of new hybrid compounds containing several heterocyclic groups namely norfloxacine, 1,2,4-triazole, 1,3,4-oxadiazole, piperazine, morpholine, thiomorpholine, 1,3,4-thiadiazole etc. was performed by conventional ...
Novel microwave assisted synthesis and antimicrobial activity of new quinolone-hybrids
(Bentham Science Publ Ltd, 2016)
Background: Carbo(thio)amid derivatives 4a, 4b were obtained starting from nalidixic acid in three steps. the acidic treatment of compound 4a generated the corresponding 1,3,4-oxadiazole (5), while the compound 4a gave ...
