ART/DHA, Artemisinin: Click to Expand ⟱
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)

ER Stress, endoplasmic reticulum (ER) stress signaling pathway: Click to Expand ⟱
Source:
Type:
Protein expression of ATF, GRP78, and GADD153 which is a hall marker of ER stress.
The endoplasmic reticulum (ER) stress signaling pathway plays a crucial role in maintaining cellular homeostasis and responding to various stressors, including those encountered in cancer. When cells experience stress, such as the accumulation of misfolded proteins, they activate a series of signaling pathways collectively known as the unfolded protein response (UPR). The UPR aims to restore normal function by enhancing the protein-folding capacity of the ER, degrading misfolded proteins, and, if the stress is unresolved, triggering apoptosis.
The activation of ER stress pathways can contribute to resistance against chemotherapy and targeted therapies. Cancer cells may utilize the UPR to survive treatment-induced stress, making it challenging to achieve effective therapeutic outcomes.

-ER stress-associated proteins include: phosphorylation of PERK, eIF2α, ATF4, CHOP and cleaved-caspase 12
