Microwave-assisted synthesis of new benzimidazole derivatives with lipase inhibition activity
(Taylor & Francis Ltd, 2014)
A practical protocol has been used for the synthesis of benzimidazoles. the reaction of iminoester hydrochlorides of phenylacetic with 4,5-dichloro-1,2-phenylenediamine under microwave irradiation leads to the benzimidazole ...
Synthesis, antibacterial and antioxidant activities of new 1-alkyl-4-(1-alkyl-4-oxo-1,4-dihydroquinolin-2-yl)pyridinium bromides
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2013)
New 1-alkyl-4-(1-alkyl-4-oxo-1,4-dihydroquinolin-2-yl)pyridinium bromides (3a k) were synthesized from 1,4'-diazaflavone [2-pyridin-4-ylquinolin-4(1H)-one] and evaluated for antibacterial and antioxidant activities. A rapid ...
An efficient synthesis of benzimidazoles via a microwave technique and evaluation of their biological activities
(Springer Wien, 2013)
A simple and practical protocol was developed for the synthesis of benzimidazoles. the protocol uses iminoester hydrochloride which is very useful in the reaction with 4,5-dichloro-1,2-phenylenediamine under microwave ...
Synthesis and evaluation of alpha-glucosidase and pancreatic lipase inhibition by quinazolinone-coumarin hybrids
(Springer, 2016)
A new series of 2-substituted quinazolin-4(3H)-one derivatives including coumarin nucleus has been synthesized and screened for their lipase and a-glucosidase inhibition properties. Among the synthesized compounds, ...
Molecular docking studies and synthesis of novel bisbenzimidazole derivatives as inhibitors of alpha-glucosidase
(Pergamon-Elsevier Science Ltd, 2016)
A series of bisbenzimidazole derivatives starting from o-phenylenediamine and 4-nitro-o-phenylenediamine were prepared with oxalic acid. Most of the reactions were conducted using both the microwave and conventional methods ...
A simple and efficient synthesis of novel inhibitors of alpha-glucosidase based on benzimidazole skeleton and molecular docking studies
(Academic Press Inc Elsevier Science, 2016)
A novel series of benzimidazole derivatives were prepared starting from o-phenylenediamine and 4-nitro-o-phenylenediamine with iminoester hydrochlorides. Acidic proton in benzimidazole was exchanged with ethyl bromoacetate, ...
Novel microwave assisted synthesis and antimicrobial activity of new quinolone-hybrids
(Bentham Science Publ Ltd, 2016)
Background: Carbo(thio)amid derivatives 4a, 4b were obtained starting from nalidixic acid in three steps. the acidic treatment of compound 4a generated the corresponding 1,3,4-oxadiazole (5), while the compound 4a gave ...
Conventional and microwave-assisted synthesis of novel 1,2,4-triazole derivatives containing tryptamine skeleton and evaluation of antimicrobial activity
(Bentham Science Publishing, 2021)
1,2,4-Triazole-3-one (3) obtained from tryptamine was transformed to the corresponding carbox(thio)amides via several steps (6a-d). Their reaction with sodium hydroxide performed the 1,2,4triazole derivatives (7a-d). ...
Synthesis and antimicrobial activity of new piperazine-based heterocyclic compounds
(Walter de Gruyter Gmbh, 2017)
The hydrazide 5, that was obtained from -1-(4-fluorophenyl) piperazine (1), was converted to the cor-responding carbothioamides 6a-c by the reaction with alkyl(aryl) isothiocyanates. the synthesis of conazole analogs 10a-f ...
Conventional and microwave irradiated synthesis, biological activity evaluation and molecular docking studies of highly substituted piperazine-azole hybrids
(Elsevier Science Inc, 2017)
Azole derivatives (3, 6) obtained starting from 1-(2-methoxyphenyl)piperazine were converted to the corresponding Mannich bases containing beta-lactame or flouroquinolone core via a one pot three component reaction. the ...
