Features:
Artemisinin a compound in a Chinese herb that may inhibit tumor growth and metastasis Artemisinin (antimalarial drugs)
Artesunic acid (Artesunate) , Dihydroartemisinin (DHA), artesunate, arteether, and artemether, SM735, SM905, SM933, SM934, and SM1044

The induction of OS in tumor cells via the production of ROS is the key mechanism of ART against cancer.
combination of ART and Nrf2 inhibitors to promote ferroptosis may have more efficient anticancer effects without damaging normal cells.

Summary:
- Pro-oxidant, mechanism related with iron (hence avoid supplements containing iron? Or perhaps take with iron?)
-ROS seems to affect both cancer and normal cells
- Delivery of artemisinin in conjugate form with transferrin or holotransferrin (serum iron transport proteins) have been shown to greatly improve its effectiveness.
- Potential direct inhibitor of STAT3
- Artemisinin synergized with the glycolysis inhibitor 2DG (2-deoxy- D -glucose)
ART Combined Therapy: Allicin, Resveratrol, Curcumin, VitC (but not orally at same time), Butyrate , 2-DG, Aminolevulinic AcidG
-possible problems with liver toxicity??

-Artesunate (ART), an artemisinin compound, is known for lysosomal degradation of ferritin, inducing oxidative stress and promoting cancer cell death.

Pathways:
- Increasing reactive oxygen species (ROS) production. This oxidative stress can cause the loss of mitochondrial membrane potential, leading to cytochrome c release and subsequent activation of caspase cascades.
- Downregulate HIF-1α
- By impairing glycolysis, artemisinin might force cells to rely on oxidative phosphorylation (OXPHOS) for energy production.
- Inhibit GLUT1 (glucose uptake), HK2, PKM2 (slow the glycolytic flux, thereby reducing the energy supply)

-Artemisinin has a half-life of about 3-4 hours, Artesunate 40 minutes and Artemether 12 hours. Peak plasma levels occur in 1-2 hour.
BioAv 21%, poor-good solubility. Artesunate (ART), a water soluble derivative of artemisinin. concentrations higher in blood, colon, liver, kidney (highly perfused organs)

Curcumin
— suppresses self-renewal and pathways (Wnt/Notch/Hedgehog).
Resveratrol
— shown to reduce CSC populations and sphere formation in multiple models.
Sulforaphane (from broccoli sprouts)
— reported to inhibit CSC properties and pathways; active in vitro and in vivo.
EGCG (epigallocatechin-3-gallate, green tea)
— reduces CSC markers and sphere formation in several cancer types.
Quercetin
— reported to inhibit CSC proliferation, self-renewal and invasiveness (breast, endometrial, others).
Berberine
— shown to suppress CSC “stemness” and reduce tumorigenic properties in multiple models.
Genistein (soy isoflavone)
— decreases CSC markers, sphere formation and stemness signaling in prostate/breast/other models.
Honokiol (Magnolia bark)
— shown to eliminate or suppress CSC-like populations in oral, colon, glioma models.
Luteolin

3382- ART/DHA,    Repurposing Artemisinin and its Derivatives as Anticancer Drugs: A Chance or Challenge?
- Review, Var, NA
AntiCan↑, antimalarial drug, artemisinin that has shown anticancer activities in vitro and in vivo.
toxicity↑, safety of artemisinins in long-term cancer therapy requires further investigation.
Ferroptosis↑, Artemisinins acts against cancer cells via various pathways such as inducing apoptosis (Zhu et al., 2014; Zuo et al., 2014) and ferroptosis via the generation of reactive oxygen species (ROS) (Zhu et al., 2021) and causing cell cycle arrest
ROS↑,
TumCCA↑,
BioAv↝, absolute bioavailability was estimated to be 21.6%. ART has good solubility and is not lipophilic
eff↝, ART would not distribute well to the tissues and might be more effective in treating cancers such as leukemia, hepatocellular carcinoma (HCC), or renal cell carcinoma because the liver and kidney are highly perfused organs.
Half-Life↓, Pharmacokinetic studies showed a relatively short t1/2 of artemisinins. For ART, t1/2 was 0.41 h
