Probing the possible molecular origin of the highly selective toxicity of antimalarial peroxide qinghaosu (artemisinin)

Chem Res Toxicol. 2003 Oct;16(10):1202-6. doi: 10.1021/tx034133k.

Abstract

The radicals derived from qinghaosu (artemisinin) showed strong tendency for intramolecular reactions and thus are unlikely to cause so much damage to cells as simple alkyl radicals, giving a clue to the extraordinarily low toxicity of this radical precursor at therapeutic doses.
