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 ...
Yearly changes of insecticide susceptiblity and possible insecticide resistance mechanisms of Anopheles maculipennis Meigen (Diptera: Culicidae) in Turkey
(Elsevier, 2013)
To evaluate the adulticide susceptibility and yearly changes of Anopheles maculipennis Meigen (Diptera: Culicidae) in Thrace, five mosquito populations were evaluated against the resistance status of four different ...
Ecological divergence between two evolutionary lineages of Hyla savignyi (Audouin, 1827) in Turkey: effects of the Anatolian Diagonal
(Brill Academic Publishers, 2013)
Most of Turkey's land area is covered by one of three biodiversity hotspots (Caucasus, Irano-Anatolian, and Mediterranean). Anatolia is one of the main corridors for postglacial colonization of Europe. Uncovering how ...
Culturable bacterial microbiota of Plagiodera versicolora (L.) (Coleoptera: Chrysomelidae) and virulence of the isolated strains
(Springer, 2013)
Plagiodera versicolora (Laicharting, 1781) (Coleoptera: Chrysomelidae) is an important forest pest which damages many trees such as willow, poplar, and hazelnut. in order to find new microbes that can be utilized as a ...
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 ...
Population structure and genetic analysis of narrow-clawed crayfish (Astacus leptodactylus) populations in Turkey
(Springer, 2014)
The genetic differentiation among Turkish populations of the narrow-clawed crayfish was investigated using a partial sequence of cytochrome oxidase subunit I gene (585 bp) of 183 specimens from 17 different crayfish ...
