Opis:: Some novel 6-fluoro chroman derivatives having 1,2,4-triazolo-[3,4-b]thiadiazole were synthesized and characterized by IR, NMR and mass spectral analysis. All synthesized compounds were screened for antimicrobial activity using broth dilution method. All the compounds showed good antimicrobial activity and compound 5e showed significant antibacterial activity.

Tematy:: 2-Oxonaphtho[2,1-b][1,4]oxazine
Schiff base
Opis:: The literature review reveal that [1,4]-oxazine derivatives represent one of the most active classes of compounds possessing wide spectrum of biodynamic activities and use as potent therapeutic agents. In the present work, a series of Schiff base of 2-(2,3-dihydro-2-oxonaphtho[2,1-b][1,4]oxazin-1-yl)acetohydrazide, 5a-5j has been synthesized using 1-aminonaphthalen-2-ol. Various aromatic aldehyde were react with carbohydrazide 4 in the presence of acid to produce the 2-oxonaphtho[2,1-b][1,4]oxazin Schiff base derivatives with good yields. All synthesized compounds were characterized by IR, NMR and Mass spectrometry analysis.

Tematy:: Chloroquinoline
antimicrobial agents
multistep synthesis
piperazine
Opis:: A series of (4-(7-chloroquinolin-4-yl)piperazin-1-yl)(substitutedphenyl)methanones were prepared via multistep synthesis which involved acrylation without base, cyclisation, hydrolysis, decarboxylation, electrophilic chlorination reactions and subsequent chloro-amine coupling with various substituted benzoyl chloride derivatives. The structure of the synthesized compounds was established by using elemental analysis, FT-IR, 1H NMR, 13C NMR and Mass spectroscopy. All the novel compounds have been tested on thin layer chromatographic plate for purity and evaluated for their antimicrobial activity against gram positive and gram negative bacteria which demonstrated moderate to good antimicrobial activity.
