New synthetised tetrazoles and their antibacterial activity
We have investigated the antibacterial activity of new synthesized organic compounds tetrazoles 4‐hidro‐3‐(1H‐tetrazol‐5‐yl) chromen‐2‐on and second compound. 4‐phenylamino‐3‐‐(1H‐tetrazol‐5‐yl) chromen‐2‐on. Our investigation is directed toward their activity against, Escherichia coli and Clebsiella spp.,. Applying the disc method we measured diameters of the inhibition zone around discs which are previously wetted with DMF solutions of compounds, 5mg/ml, 3mg/ml and 1mg/ml.
