Investigating the antioxidant and antimicrobial activities of different vinegars
(Springer, 2017)
In this study, the antioxidant contents and the antimicrobial activities of 18 vinegar samples were investigated. For this purpose, total flavonoid contents (TFC) and total phenolic contents (TPC) of different vinegar ...
New pyridine derivatives as antiurease inhibitors: Synthesis and their evaluation for antimicrobial activities
(Editura Acad Romane, 2017)
6-Morpholin-4-ylpyridin-3-amine (3) gathered starting from morpholine by two steps was converted into the corresponding arylidenehydrazides through the reaction with several aromatic aldehydes. the treatment of compound 3 ...
Structure-based hybridization, conventional and microwave irradiated synthesis, biological evaluation and molecular docking studies of new compounds derived from thiomorpholin
(Bentham Science Publ Ltd, 2017)
Background: the amine 2 obtained via two steps starting from thiomorpholine was converted into the corresponding 1,3-thiazole (4), arylmethileneamino (5a- d) and hydrazide (7) derivatives using conventional and also microwave ...
Synthesis and antimicrobial activity evaluation of new norfloxacine-azole hybrids
(Walter de Gruyter Gmbh, 2018)
Norfloxacin-azole hybrids 3 and 6a,b were synthesized starting from norfloxacin. the treatment of these compounds with amines as a one-pot three-component reaction produced the corresponding amino derivatives 4a,b, 7a-g ...
Structure-based hybridization, microwave prompted synthesis and biological evaluation of novel 4-(2-fluoro-4-nitrophenyl)morpholine derivatives
(Bentham Science Publ Ltd, 2018)
1,3,4-oxadiazole-2-thiole 6 was obtained from 4-(2-fluoro-4-nitrophenyl)morpholine (2) by the reduction of its nitro group and the sequential treatment of the resulting amine with ethyl bro-moacetate, hydrazine hydrate, ...
Piperazine-azole-fluoroquinolone hybrids: Conventional and microwave irradiated synthesis, biological activity screening and molecular docking studies
(Academic Press Inc Elsevier Science, 2019)
A series of new 1,2,4-triazole and 1,3,4-oxadiazole derivatives was obtained via several steps sequential reactions of phenyl piperazine. Then, these compounds were converted to the corresponding fluoroquinolone hybrids ...
Novel imidazo[2,1-b] [1,3,4]thiadiazole (ITD) hybrid compounds: Design, synthesis, efficient antibacterial activity and antioxidant effects
(Academic Press Inc Elsevier Science, 2019)
In this study, novel imidazo[2,1-b] [1,3,4]thiadiazole (ITD) compounds were synthesized and their antimicrobial and antioxidant capacity was examined. the C-2 position of the ITD structure was fixed with the 3,4-hydroxybenzene ...
Synthesis of novel antipyrine derivatives possessing remarkable antimicrobial activities
(Wiley-V C H Verlag Gmbh, 2019)
In this study, new triazole, thiazole, oxazole and Mannich bases were synthesized starting from antipyrine. All the newly synthesized compounds were screened for their antimicrobial activities against some test microorganisms ...
Determination of the antimicrobial and antibiofilm effects and 'Quorum Sensing' inhibition potentials of Castanea sativa Mill. extracts
(Univ Agr Sci & Veterinary Med Cluj-Napoca, 2020)
The rapid rise of resistance causes existing antibiotics to become dysfunctional. Therefore, search for new antimicrobial active ingredients has increased in recent years. in this study, flower extracts of Castanea sativa ...
Synthesis and solvent-dependent photophysics of a novel fluorescent triazole-coumarin-based dye
(Wiley, 2020)
Synthesis of a new coumarin-triazole-based dye and its photophysical parameters such as absorption, fluorescence emission, and fluorescence quantum yield were investigated. Studies have shown that the present dye has ...
