In vitro studies to fourteen previously synthesized chromone-tetrazoles and four novel fluorine-containing analogs were conducted against pathogenic protozoan (Entamoeba histolytica), pathogenic bacteria (Pseudomonas aeruginosa, and Staphylococcus aureus), and human fungal pathogens (Sporothrix schenckii, Candida albicans, and Candida tropicalis), which have become in a serious health problem, ...
In attempt to find new pharmacologically active molecules, we report here the synthesis and in vitro anti-inflammatory activity of various 1-[5-(substituted phenyl)-1-phenyl-4,5dihydro-1H-pyrazol-3-yl]-5-phenyl-1H-tetrazole (IV a-h).The anti-inflammatory activity of title compounds were examined by denaturation of proteins method. All the compounds exhibited weak to potent anti-inflammatory act...
A mild protocol for the synthesis of diaryl and heteroaryl sulfides is described. In a one-pot procedure, thiols are converted to sulfenyl chlorides and reacted with arylzinc reagents. This method tolerates functional groups including aryl fluorides and chlorides, ketones, as well as N-heterocycles including pyrimidines, imidazoles, tetrazoles, and oxadiazoles. Two compounds synthesized by this...
This combined experimental, theoretical and comparative study details the syntheses and chemical characterisation of two new energetic polynitromethyl tetrazole derivatives, namely, 2-(2-nitro-2-azapropyl)-5-(trinitromethyl)-2 H-tetrazole and its fluorine-containing analogue 2-(2-nitro-2-azapropyl)-5-(fluorodinitromethyl)-2 H-tetrazole. Their crystal structures and energetic behaviour are compa...
