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

A rapid, selective, and sensitive LC-APCI-MS method is developed in this study for detecting and analyzing tryptanthrin, indigo, and indirubin in daqingye and banlangen, which are, respectively, the leaves and roots of Isatis indigotica and Strobilanthes cusia in traditional Chinese

New drugs are needed for treatment of Toxoplasma gondii infections. We tested derivatives of principles found in Isatis indigotica for in vitro efficacy against T. gondii infection. Indirubin-3'-oxime analogs showed modest micromolar activity, while tryptanthrin derivatives displayed 50% inhibitory doses
