Synopsıs of the genus cota (anthemıdeae, asteraceae) ın Turkey
(Ankara Üniversitesi Fen Fakültesi, 2020)The morphological features of Cota were studied based on our specimens collected between 2005 and 2019 in Turkey and herbarium specimens from various herbaria. As a result of the obtained systematic and floristic findings ... -
Synthesis and antioxidant activity evaluations of melatonin-based analogue indole-hydrazide/hydrazone derivatives
(2012)Melatonin (MLT) is a hormone synthesized from the pineal gland. It is a direct scavenger of free radicals, which is related to its capability to defend cells from oxidative stress. Recently MLT-related compounds are under ... -
Synthesis and antiradical activity of alkyl derivatives of 5-(5-methyl-1h-pyrazol-3-yl)-4-phenyl-4h1,2,4-triazole-3-thiol
(Ankara Üniversitesi, 2020)Objective: The aim of the work was to develop effective methods for the synthesis of biologically active heterocyclic systems containing 1,2,4-triazole and pyrazole. Material and Method: Chemical structures of synthesized ... -
Synthesis and characterization of new phosphor based MTiO3
In this study, new titanate phosphors were synthesized. The Dy3+, Eu3+, Ho3+ rare-earth ions were used as dopants to CaTiO3, SrTiO3, and BaTiO3 host crystals. The optimization of reaction conditions were carried out by ... -
Synthesis and evaluation of antioxidant activity of new quinoline-2-carbaldehyde hydrazone derivatives: bioisosteric melatonin analogues
(2015)Overproduction of reactive oxygen species results in oxidative stress that can cause fatal damage to vital cell structures. It is known that the use of antioxidants could be beneficial in the prevention or delay of numerous ... -
Synthesis and evaluation of in vitro antioxidant capacities of some benzimidazole derivatives
(2006)New, except 1d, melatonin analogue benzimidazole derivatives were synthesized and characterized in the present study. The potential role of melatonin as an antioxidant by scavenging and detoxifying ROS raised the possibility ... -
Synthesis and potent antimicrobial activity of some novel N-(Alkyl)-2-phenyl-1H-benzimidazole-5-carboxamidines
(2005)A series of 22 novel 1,2-disubstituted-1H-benzimidazole-N-alkylated-5-carboxamidine derivatives were synthesized and evaluated for in vitro antibacterial activity against S. aureus and methicillin resistant S. aureus (MRSA), ... -
