Biochem/physiol Actions

Tryptanthrin is a plant alkaloid with anti-inflammatory and anti cancer activities. Tryptanthrin blocks leukotriene production in neutrophils and in whole blood assays, and in an in vivo rat pleurisy model. The compound also inhibits P-glycoprotein, and sensitizes resistant cancer cell lines to killing by cytotoxic agents.

Tryptanthrins have potential therapeutic activity against a wide variety of pathogenic organisms, although little is known about their mechanism. Activity against Escherichia coli, however, has not been examined. The effects of tryptanthrin (indolo[2,1-b]quinazolin-6,12-dione) and nine derivatives on growth, survival, and

Bioassay-guided chromatographic separation of the cytotoxic MeOH extract of Phaius mishmensis led to the isolation of two known and six new indoloquinazolinones, phaitanthrins A-E (1-5) and methylisatoid (6). The structures of the new compounds were elucidated by spectroscopic analysis. Phaitanthrin
