A novel series of compounds were synthesized by cyclic condensation reaction of substituted isothiocyanate (2a-c) with 2-thiophenecarboxylic acid hydrazide (1) in the presence of ethyl alcohol, to obtain intermediate thiosemicarbazides (3a-c), which were further treated with sodium hydroxide in the presence of ethanol to obtain triazole derivatives (4a-c).(More)
In this study, it was aimed to examine the antioxidant and antihepatotoxic effects of hydroxyurea derivative Schiff bases on serum biochemical parameters (AST, ALT, LDH, urea, creatinine and total bilirubin) and antioxidant parameters (SOD, CAT, GPx, MDA). In this study, a total of 49 adult male Wistar rats was examined and they were divided into 7 equal(More)
The 1,2,4-triazole and its derivatives were reported to exhibit various pharmacological activities. Mannich bases possess potent biological advantages due to being antibacterial, antifungal, antiinflammatory, antimalarial and. They also have pesticide properties. As previously reported, Mannich bases derivatives were synthesized [1]. In this study, the(More)
In this study, the effects of Mannich bases containing bis-1,2,4-triazole on the levels of in vivo malondialdehyde (MDA) and antioxidant vitamins (A, E, C) were examined in serum, livers and kidneys of rats. DA and vitamin (A, E, C) levels were determined by high performance liquid chromatography (HPLC). Antioxidant effect was investigated by determining(More)
We stadied some biologically active compounds, radical scavenging capacities, and antimicrobial activities in Hypericum uniglandulosum extracts. It was found that palmitic acid (12.16 ± 0.69%), oleic acid (3.45 ± 0.17%), and α-linolenic acid (17.15 ± 0.84%) were the dominant fatty acids in the extracts. It was concluded that the extracts contained(More)
Aminophosphinic acids which are organophosphorus compounds widely investigated for potential production of antibacterial, antitumor and antiviral materials. In vitro antioxidant, cytotoxic and antimicrobial activities of synthesized novel compounds of 8 different bis(β-amino alkyl)phosphinic acids (4a-h) were investigated on MCF-7 breast adenocarcinoma cell(More)
