  Antimicrobial Activity of Tryptanthrins in Escherichia coli

  摘要：

  Tryptanthrins have potential therapeutic activity against a wide variety of pathogenic organisms, although little is known about their mechanism. Activity against Escherichia colt, however, has not been examined. The effects of tryptanthrin (indolo[2,1-b]quinazolin-6,12-dione) and nine derivatives on growth, survival, and mutagenesis in E. colt were examined. Analogues with a nitrogen atom at the 4-position of tryptanthrin stopped log phase growth of E. coli cultures at concentrations as low as 5 mu M. Tryptanthrins decreased viability during incubation with cells in buffer by factors of 10(-2) to < 10(-6) at 0.2-40 mu M. Derivatives with an oxime group at the 6-position exhibited the greatest bactericidal activity. Most tryptanthrins were not mutagenic in several independent assays, although the 4-aza and 4 aza-8-fluoro derivatives increased frameshift mutations about 22- and 4-fold, respectively. Given the structure of trypanthrins, binding to DNA may occur by intercalation. From analysis using a sensitive linking number assay, several tryptanthrins, especially the 4-aza and 6-oximo derivatives, intercalate into DNA.
