Human health risk assessment of heavy metals accumulation in different genders and tissues of whiting fish (Merlangius merlangus euxinus Nordmann, 1840) from Rize, Turkey
(Elsevier, 2024)
The contamination of fish resulting from marine pollution is a major concern, as it poses potential adverse effects on human health. Therefore, heavy metal concentrations (Cr, Fe, Ni, Cu, Zn, and Pb) in different genders ...
Experimental and computational studies on 4-[(3,5-dimethyl-1H-pyrazol-1-yl) methoxy]phthalonitrile and synthesis and spectroscopic characterization of its novel phthalocyanine magnesium(ii) and tin(ii) metal complexes
(Elsevier B.V., 2013)
The molecular structure of the substituted phthalonitrile was analyzed crystallographically and compared with optimized geometric structure. The structural properties of the compound such as energy, vibrational frequency, ...
Microwave-assisted synthesis of some 1, 2, 4-triazol-3-ones and potentiometric determination of their pKa in amfiprotic and dipolar aprotic-water mixtures
(0-Belirlenecek, 2013)
The novel 5-alkyl(aryl)-4-(aryl)-2, 4-dihydro-3H-1, 2, 4-triazol-3-ones (1-12) were synthesized by reaction of (N?-ethoxycarbonyl)-4-alkyl(aryl)hydrazonic acid ethyl ester with primary amines by microwave irradiation. ...
Synthesis and in vitro antioxidant activities of novel 4-(3-methyl-2- thienylmethyleneamino)-4,5-dihydro-1H-1,2,4-triazol-5-one derivatives with their acidic properties
(2013)
In the present study 3-alkyl(aryl)-4-amino-4,5-dihydro-1H-1,2,4-triazol-5- ones 2a-i reacted with 3-methyl-thiophene-2-carboxyaldehyde to afford the corresponding 3-alkyl(aryl)-4-(3- methyl-2-thienylmethyleneamino)-4,5-dihydro- ...
Evaluation of phenolic compounds in Tilia rubra Subsp. caucasica by HPLC-UV and HPLC-UV-MS/MS
(Taylor & Francis Ltd., 2014)
Profile of phenolic compounds of Tilia rubra subsp. caucasica was measured by high performance liquid chromatography coupled with ultraviolet and tandem mass spectroscopy. Three different extraction methods (methonolic, ...
Synthesis of benzimidazoles containing piperazine ring as potential therapeutic agents against diabetes mellitus and antioxidant activities
(Elsevier, 2024)
We synthesized a novel 6-(4-substitue-piperazin-1-yl)-2-aryl-1H-benzimidazole derivatives starting from 5-(4-substitue-piperazin-1-yl)-2-nitroaniline with different aldehydes. A quick "onepot" nitro reductive cyclization ...
Some schiff bases containing eugenol and guaiacol: Comparison of urease inhibition and anti-helicobacter pylori activities with Its azo analogs
(Springer, 2024)
To improve and develop our monotherapeutic approach for Helicobacter pylori infection, some Schiff base compounds containing eugenol and guaiacol were synthesized and their antioxidant capacities, urease enzyme inhibition, ...
Preparation and characterization of the highly efficient tetraphenylimidazole substituted Phthalocyanine/ZnO composite and investigation of its effect on the photocatalytic degradation of Rhodamine B and 2,4,6-trichlorophenol
(Elsevier, 2024)
Growing concerns about industrial waste-induced environmental degradation have driven research towards sustainable solutions. Photocatalytic degradation, fueled by light and avoiding harmful chemicals, offers a promising ...
A facile ultrasonic synthesis approach to 3-H-quinazolinethione derivatives and their urease inhibition studies
(Taylor & Francis Ltd., 2024)
In this study, a new series of 3H-quinazoline-4-thione derivatives were synthesized under ultrasonic irradiation conditions with high yield in a short time. The new compounds were characterized by FT-IR,H-1, and C-13 NMR ...
A zirconium metal–organic framework functionalized with a S/N containing carboxylic acid (MOF-808(Zr)-Tz) as an efficient sorbent for the ultrafast and selective dispersive solid phase micro extraction of chromium, silver, and rhodium in water samples
(Elsevier, 2024)
Metal-organic frameworks (MOFs) are good adsorbents for targeted chemicals with their adjustable properties. Herein, we prepared a zirconium based MOF (MOF-808(Zr)) and functionalized it employing 2-mercapto-4-methyl-5-t ...
