Abstract

|
7-Alkyl-2-aminophenazine-5,10-dioxides bearing butyl, hexyl and octyl group were synthesized by the reaction of 4-aminophenol with 6-alkylbenzofuroxans which had been obtained from aniline and n-alkyl alcohols. And 2-aminophenazine-5,10-dioxide was prepared by the reaction of 4-aminophenol with benzofuroxan. Infrared, nuclear magnetic resonance spectrophotometers, and elemental analyzer were employed to identify the products concerned with the synthetic processes. Surface tension of aqueous solutions of these phenazine derivatives was determined by surface tensiometer and it was found that the surface tension decreased with an increase of the number of carbon in the alkyl group. Antimicrobial activities were evaluated in terms of minimum inhibitory concentration by a dilution method. The butyl derivative showed the highest activity among these derivatives. It was observed that the antimicrobial activity of these alkyl substituted 2-aminophenazine-5,10-dioxides was stronger than that of 2-aminophenazine-5,10-dioxide.
