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). ...
Microwave-assisted synthesis of novel mannich base and conazole derivatives containing biologically active pharmacological groups
(Bentham Science Publishers, 2021)
Background: The aim of this study was to synthesize new Mannich bases and conazol derivatives with biological activity by the microwave-assisted method. Introduction: 1,2,4-Triazole-3-one (3) acquired from tryptamine was ...
Synthesis of Some New Ciprofloxacin Hybrids as Potential Antimicrobial Agents
(Wiley, 2017)
A new series of ciprofloxacin hybrid compounds as new type of antimicrobial agents were synthesized and evaluated for antibacterial activity against Gram-positive and Gram-negative bacteria.
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 ...
Conventional and microwave-assisted total synthesis, antioxidant capacity, biological activity, and molecular docking studies of new hybrid compounds
(Wiley, 2017)
Thiomorpholine was converted to the corresponding 1,3,4-oxadiazole (4), arylidenehydrazide (5a-e), and 1,2,4-triazole (7a and, 7b) derivatives via the formation of hydrazide (3). Compounds 4 and 7 were next converted to ...
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, ...
