Synthesis and biological evaluation of new 1,2,4-triazole derivatives with their potentiometric titrations
(Springer Birkhauser, 2015)
In the present study, 3-alkyl(aryl)-4-amino-4,5-dihydro-1H-1,2,4-triazol-5-ones (1a, b, d-g) reacted with 3-phenoxybenzaldehyde to afford 3-alkyl(aryl)-4-(3-phenoxy-benzylidenamino-4,5-dihydro-1H-1,2,4-triazol-5-ones (2a, ...
Pollinarium morphology of Vincetoxicum (Apocynaceae: Asclepiadoideae) in Turkey
(Magnolia Press, 2015)
In this study, the pollen morphology of 20 representatives of ten taxa of Vincetoxicum from Turkey was observed under a scanning electron microscope and light microscope. Observations showed that each flower contained five ...
Synthesis and study of alpha-glucosidase inhibitory, antimicrobial and antioxidant activities of some benzimidazole derivatives containing triazole, thiadiazole, oxadiazole, and morpholine rings
(Springer, 2015)
A new series of 2-(4-bromobenzyl)- and 2-(4-fluorobenzyl)-1H-benzimidazole derivatives containing 1,2,4-triazole, 1,3,4-thiadiazole, 1,3,4-oxadiazole, and morpholine rings has been synthesized. the structures of the newly ...
Age structure and body size variation in populations of darevskia bithynica (Mehely, 1909) (Reptilia: Lacertidae) from different altitudes in North-western Turkey
(Inst Zoology, Bas, 2015)
We present the first data of body size and age structure (based on the skeletochronological examination) of Darevskia bithynica from two localities characterised with different altitudes, i.e. Zonguldak (50 m) and Bolu ...
