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 ...
Preparation and antimicrobial activity evaluation of some new bi- and triheterocyclic azoles
(Springer Birkhauser, 2013)
Synthesis of the carbothioamides (5, 13, 22) was performed starting from 3H-1,2,4-triazol-3-ones (2, 17) by several steps, and then, these carbothioamides was converted to triheterocyclic compounds incorporating 1,2,4-triazole, ...
Design, synthesis and biological activities of some 7-aminocephalosporanic acid derivatives
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2013)
The treatment of 7-ACA with 4-substituted benzensulfonyl chlorides afforded the compounds containing 4-nitro/aminophenyl sulfonylamino moiety in the cephalosporanic acid skeleton (2, 4). the synthesis of the cephalosporanic ...
Microwave assisted synthesis of some hybrid molecules derived from norfloxacin and investigation of their biological activities
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2013)
Norfloxacin was converted to 7-(4-amino-2-fluorophenyl)piperazin derivative (2) via the formation of nitro compound. the synthesis of the norfloxacin derivatives containing 1,3-thiazole or 1,3-thiazolidin moiety was performed ...
Ecofriendly solventless synthesis and reduction reaction of some triazole compounds and evaluation of their antimicrobial activity
(Taylor & Francis Inc, 2013)
A number of triazole-3-one compounds have been synthesized, and reduction of the carbonyl group in the molecule has been carried out to give a corresponding hydroxyl group that possesses asymmetric carbon atom in good ...
Antimicrobial and antioxidant activity of the essential oil of the Turkish endemic species Achillea Phrygia Boiss. & Bal.
(Taylor & Francis Ltd, 2014)
The essential oil obtained from the dried flowering aerial parts of Achillea phrygia Boiss & Bal. by hydrodistilation was analysed by gas chromotography-mass spectrometry. Camphor (35.55 %), 2-furaldehyde (16.59 %) and ...
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 ...
