Artemisinin-d3 (Synonyms: Qinghaosu-d3; NSC 369397-d3)

Artemisinin-d₃ is intended for use as an internal standard for the quantification of artemisinin . Artemisinin is an endoperoxide antimalarial agent with anticancer activity.^1,2 It reduces the growth of various P. falciparum strains in vitro (IC₅₀s = 3.98-20.36 nM) and reduces parasitemia in mice infected with P. falciparum with a curative dose (CD₅₀) value of 140 mg/kg.^1,3 It also reduces P. berghei infection in mice (ED₅₀ = 5.6 mg/kg per day).⁴ Artemisinin (100-400 μM) induces cell cycle arrest in the G₀/G₁ phase and apoptosis and inhibits growth of SK-N-AS, BE(2)-C, SK-N-DZ, and SHEP1 neuroblastoma cells in a time- and concentration-dependent manner.² It also suppresses BE(2)-C cell colony formation in a soft agar assay and reduces tumor growth in a BE(2)-C mouse xenograft model. Formulations containing artemisinin have been used in combination therapies for the treatment of malaria.
