Biological Activity

Artesunate is a semi-synthetic artemisinin derivative and potent antimalarial agent that functions as an EXP1 inhibitor and STAT3 pathway modulator. It induces reactive oxygen species production, suppresses STAT3 signaling, and inhibits cancer cell proliferation, displaying selective cytotoxicity against small cell lung carcinoma H69 cells with an IC50 below. Furthermore, artesunate demonstrates antiparasitic efficacy and targeted toxicity toward malignant over normal cells. [1][2]

FAQ
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
  • Preheat media/saline to 37°C.
  • Mix rapidly (pipette/vortex) upon addition.
  • For complex mixes, always add the aqueous phase last.
  • Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
