Some new 4-aryl-2-thiazolylhydrazones
(1997)
In this study, three series of 4-aryl-2-thiazolylhydrazones were synthesized using three different thiosemicarbazones. Structures of the compounds were elucidated by IR, 1H NMR and elemental analysis. The prepared compounds ...
Synthesis and Biological Evaluation of Some New Amide Moiety Bearing Quinoxaline Derivatives as Antimicrobial Agents
(Georg Thieme Verlag Kg, 2015)
In this study, we aimed to synthesize some new quinoxaline derivatives bearing amide moiety and to evaluate their antimicrobial activity. A set of 16 novel compounds of N-[2,3-bis(4-methoxy/methylphenyl)quinoxalin-6-yl]- ...
Synthesis and biological activities of new hydrazide derivatives
(Taylor & Francis LTD, 2009)
The synthesis of a new series of imidazo[1,2-a]pyrazine-2-carboxylic acid arylidene-hydrazides is described. The chemical structures of the compounds were elucidated by IR, H-1-NMR, FAB(+)-MS spectral data. Their biological ...
Fighting Against Alzheimer's Disease: Synthesis of New Pyrazoline and Benzothiazole Derivatives as New Acetylcholinesterase and MAO Inhibitors
(Bentham Science Publ LTD, 2018)
Background: Alzheimer's Disease (AD) is a complicated neurodegenerative disorder with a multifaceted pathogenesis. AD, characterized by gradual memory loss, falling in language ability and other cognitive deterioration, ...
Synthesis and biological evaluation of new pyrazolone Schiff bases as monoamine oxidase and cholinesterase inhibitors
(Academic Press Inc Elsevier Science, 2019)
In the current work, Schiff base derivatives of antipyrine were synthesized. The chemical characterization of the compounds was confirmed using IR, H-1 NMR, C-13 NMR and mass spectroscopies. The inhibitory potency of ...
Synthesis and biological evaluation of some hydrazone derivatives as new anticandidal and anticancer agents
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2012)
New hydrazone derivatives were synthesized via the nucleophilic addition-elimination reaction of 2-[(1-methyl-1H-tetrazol-5-yl]thio)]acetohydrazide with aromatic aldehydes/ketones. The compounds were tested in vitro against ...
Synthesis of 1-acetyl-3-(2-thienyl)-5-aryl-2-pyrazoline derivatives and evaluation of their anticancer activity
(Informa Healthcare, 2013)
In the present study, 1-acetyl-3-(2-thienyl)-5-aryl-2-pyrazoline derivatives (1-6) were synthesized via the ring closure reaction of 1-(2-thienyl)-3-aryl-2-propen-1-ones with hydrazine hydrate in acetic acid. The chemical ...
Studies on 1,2,4-triazole derivatives as potential anti-inflammatory agents
(Wiley-V C H Verlag GMBH, 2007)
The reaction of acetic or propionic acid hydrazides with various aryl/alkyl isothiocyanates gave thiosemicarbazides which furnished the 1,2,4-triazoles by alkali cyclization. The 4-aryl/allcyl-5-(1phenoxyethyl)-3-[N-(sub ...
