Tryptanthrin is a plant alkaloid with anti-inflammatory and anti cancer activities.
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.

Overexpression of GSTpi and underexpression of Topo II expression are associated with multidrug resistance (MDR) phenotype through nontransporter pathway. Tryptanthrin, a quinazoline derivative, was reported to sensitize resistant cells to doxorubicin by downregulation of MDR1 expression. This study aims to
