Artemisinin (ART) is a sesquiterpene lactone natural product that is widely used to treat multi-drug resistant strains of malaria. Artemisinin and its derivatives are also selectively cytotoxic to cancer cells, which can be modulated by altering heme synthesis. Cytotoxicity to cancer cells is thought to involve generation of oxidative stress, although conflicting data exist. We have analyzed reactive oxygen species (ROS) generation using the fluorescent probes 2',7'-dichlorodihydrofluorescein… CONTINUE READING
