Cyclization of some carbothioamide derivatives containing antipyrine and triazole moieties and investigation of their antimicrobial activities
(Elsevier, 2010)Acetohydrazide derivative containing both antipyrine and triazole nuclei (5) was obtained starting from ethyl hydrazinecarboxylate derivative (2) and 4-aminoantipyrine (1) by three steps. The treatment of compound 5 with ... -
DNA binding, antioxidant and antimicrobial activities of homo- and heteronuclear copper(II) and nickel(II) complexes with new oxime-type ligands
(Elsevier, 2010)Some homo- and heteronuclear Cu(II) and Ni(II) complexes of new oxime-type ligands were tested against several pathogenic microorganisms to assess their antimicrobial potentials. The antimicrobial activities of complexes ... -
Synthesis and antimicrobial activities of some new 1,2,4-triazole derivatives
(TUBİTAK, 2010)The synthesis of ethyl [3-(cyanomethyl)-5-alkyl-4H-1,2,4-triazol-4-yl] carbamates (2a-d) was performed starting from ethyl 2-[ethoxy(4-(aryl)methylene] hydrazinecarboxylates (1a, 1b). The treatment of 2a with thiosemicarbazide ... -
DNA-binding properties of the bacillus subtilis and aeribacillus pallidus AC6 σD proteins
(2011)?D proteins from Aeribacillus pallidus AC6 and Bacillus subtilis bound specifically, albeit weakly, to promoter DNA even in the absence of core RNA polymerase. Binding required a conserved CG motif within the -10 element, ... -
Exogenous Salicylic acid alleviates effects of long term drought stress and delays leaf rolling by inducing antioxidant system
(Kluwer Academic Publishers, 2011)Salicylic acid (SA) is one of the important signal molecules modulating plant responses to environmental stress. In this study, the effects of exogenous SA on leaf rolling, one of drought avoidance mechanisms, and antioxidant ... -
A skeletochronological study of age, growth and longevity of Rana macrocnemis populations from four locations at different altitudes in Turkey
(Koninklijke Brill NV, 2011)We examined life-history traits such as population age structure, growth and longevity of Iranian Long-Legged frogs (Rana macrocnemis) from 4 different locations at different altitudes in Turkey by skeletochronology performed ... -
The relations between antioxidant enzymes and chlorophyll fluorescence parameters in common bean cultivars differing in sensitivity to drought stress
(Springer, 2011)Effects of the antioxidant system and chlorophyll fluorescence on drought tolerance of four common bean (Phaseolus vulgaris L.) cultivars were studied. The cultivars were positioned in the order of a decrease in their ... -
Antimicrobial activity and volatile constituents of the flower, leaf, and stem of Paeonia daurica grown in Turkey
(TÜBİTAK, 2011)The volatile constituents of the essential oils from the flower, leaf, and stem of Paeonia daurica Andrews were analyzed by GC and GC-MS. A total of 74 compounds were identified, constituting over 95.0%, 80.8%, and 98.2% ... -
Comparison of foliar anatomy of Scorzonera L. (Asteraceae) taxa from North East Anatolia
