Syntheses and evaluation of 3-(3-bromo phenyl)-5-phenyl-1-(thiazolo [4,5-b] quinoxaline-2-yl)-2-pyrazoline derivatives

A variety of 3-(3-bromo phenyl)-5-phenyl-1-(thiazolo [4,5-b] quinoxaline-2-yl)-2-pyrazoline were obtained by the refluxing of 1-N-thiocarbamoyl 3,5-diphenyl-2-pyrazoline with 2,3-dichloroquinoxaline. The chemical structures of the compounds were elucidated by UV, IR, 1H NMR, and 13C NMR spectroscopy. The purity of the compounds was confirmed by their elemental analysis. The antiamoebic activity of these compounds was evaluated by microdilution method against HMI:IMSS strain of Entamoeba histolytica and the IC50 values were compared with the standard drug metronidazole. Some of the quinoxaline derivatives showed less IC50 values than metronidazole. To elucidate the toxic effect, MTT assay was performed using kidney epithelial cell line. The results showed that all the compounds are non-toxic.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 2213-63-0 is helpful to your research. Application of 2213-63-0

PHOTOLYTIC RING-EXPANSIONS OF 4-AZIDOQUINOLINES AND 6-AZIDODIAZINES: SOME UNEXPECTED AZEPINE RING-OPENING REACTIONS

Photolysis of 6-azidoquinazoline in MeOH-KOMe-dioxan yields 8,9-dihydro-5,7-dimethoxy-5H-pyrimido<5,4-c>azepine (5) which on acid hydrolysis ring-opens to the pyrimidine-carbaldehyde (7).The mechanism of formation of this unexpected dimethoxypyrimido-azepine is discussed and related to previous similar results involving 6-azido-2,3-dihydrofuro- and 6-azido-2,3-dihydrothieno<2,3-b>quinolines. In contrast, 6-azidoquinoxaline and 6-azido-2-chloro-4-methylquinoline on photolysis under similar conditions undergo ring expansion to the expected pyrazino<2,3-c>– and pyrido<3,2-c>azepines (22a) and (17) respectively.However, photolysis of the latter azide in MeOH-dioxan yields the 3-(2-pyridyl)propenonitrile derivative (18) in a reaction analogous to that undergone by 6-azidophenazine.
