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 ...
Co-overexpressing a plasma membrane and a vacuolar membrane sodium/proton antiporter significantly improves salt tolerance in transgenic arabidopsis plants
(Oxford Univ Press, 2016)
The Arabidopsis gene AtNHX1 encodes a vacuolar membranebound sodium/proton (Na+/H+) antiporter that transports Na+ into the vacuole and exports H+ into the cytoplasm. the Arabidopsis gene SOS1 encodes a plasma membranebound ...
Synthesis, antibacterial and antioxidant activities of new 1-alkyl-4-(1-alkyl-4-oxo-1,4-dihydroquinolin-2-yl)pyridinium bromides
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2013)
New 1-alkyl-4-(1-alkyl-4-oxo-1,4-dihydroquinolin-2-yl)pyridinium bromides (3a k) were synthesized from 1,4'-diazaflavone [2-pyridin-4-ylquinolin-4(1H)-one] and evaluated for antibacterial and antioxidant activities. A rapid ...
Body size and age structure of a highland population of Hyla orientalis BEDRIAGA, 1890, in northern Turkey
(Pensoft Publishers, 2013)
Body size and age structure of a highland population of Hyla orientalis BEDRIAGA, 1890 (77 = 41) from Kantarh, located at about 800 m a.s.l. in the Black Sea Region of Turkey, was studied using skeletochronology. the maximum ...
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 ...
Studies on synthesis, structure, and DNA cleaving of homo-dinuclear Mn(II), Cu(II), Ni(II), and Zn(II) complexes with a heterocycle-based macroacyclic Schiff base
(Springer Wien, 2013)
(E,E',E'',E''')-N,N',N'',N'''-[(1,2-ethenyliden)tetrakis[methylenoxy(2,1-naphthalinediyl)methylidyne]tetrakis[1,2,4-triazol-4-amine] and its novel homo-dinuclear Mn(II), Ni(II), Cu(II), and Zn(II) complexes have been ...
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 ...
An efficient synthesis of benzimidazoles via a microwave technique and evaluation of their biological activities
(Springer Wien, 2013)
A simple and practical protocol was developed for the synthesis of benzimidazoles. the protocol uses iminoester hydrochloride which is very useful in the reaction with 4,5-dichloro-1,2-phenylenediamine under microwave ...
