Cloning, expression, and characterization of a novel CTP synthase gene from Anoxybacillus gonensis G2
(2014)
The cytidine-5'-triphosphate (CTP) synthase (EC 6.4.3.2) gene (pyrG) was cloned and sequenced from the thermophilic bacterium Anoxybacillus gonensis G2 (Ago). The gene is 1590 bp in length and encodes a protein of 530 amino ...
Microwave-assisted synthesis of some hybrid molecules containing penicillanic acid or cephalosporanic acid moieties and investigation of their biological activities
(Springer Birkhauser, 2014)
Ethyl 4-amino-2-fluorophenylpiperazin-1-carboxylates containing a 1,3-oxazol(idin)e, 5-thioxo-1,2,4-triazole, 1,3,4-thiadiazole, 5-thioxo-1,3,4-oxadiazole, or 1,3-thiazole nucleus were obtained starting from ethyl ...
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 ...
Microwave-assisted synthesis and biological evaluation of some benzimidazole derivatives containing a 1,2,4-triazol ring
(Wiley-V C H Verlag Gmbh, 2013)
A new series of 2-(4-(trifluoromethyl)phenyl)-1H-benzo[d]imidazole derivatives containing a 1,2,4-triazole ring were synthesized via microwave technique. This efficient procedure provides pure products within a few minutes. ...
Design, synthesis and biological activities of some 7-aminocephalosporanic acid derivatives
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2013)
The treatment of 7-ACA with 4-substituted benzensulfonyl chlorides afforded the compounds containing 4-nitro/aminophenyl sulfonylamino moiety in the cephalosporanic acid skeleton (2, 4). the synthesis of the cephalosporanic ...
Microwave assisted synthesis of some hybrid molecules derived from norfloxacin and investigation of their biological activities
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2013)
Norfloxacin was converted to 7-(4-amino-2-fluorophenyl)piperazin derivative (2) via the formation of nitro compound. the synthesis of the norfloxacin derivatives containing 1,3-thiazole or 1,3-thiazolidin moiety was performed ...
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 pharmacological activities of some new 2-[1-Heptyl-3-(4-methoxybenzyl)-5-oxo-1,5-dihydro-4H-1,2,4-triazol-4-yl] acetohydrazide derivatives
(Walter de Gruyter Gmbh, 2014)
In the present investigation, the key intermediate acetohydrazide derivative 5 was synthesized starting from 3-(4-methoxybenzyl)-4-amino-4,5-dihydro-1,2,4-triazol-5-one (1) by a four-step reaction. Thiosemicarbazides 6a-f ...
Synthesis of some new 1,2,4-triazole derivatives starting from 3-(4-chlorophenyl)-5-(4-methoxybenzyl)-4H-1,2,4-triazol with anti-lipase and anti-urease activities
(Wiley-V C H Verlag Gmbh, 2014)
In the present study, starting compound 4 was prepared by deamination of compound 2 in the presence of hypophosphorous acid and sodium nitrite. Treatment of compound 4 with ethyl bromoacetate produced ethyl[3-(4-chloroph ...
