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.

- Selectivity: Cancer Cells vs Normal Cells


selectivity, selectivity: Click to Expand ⟱
Source:
Type:
The selectivity of cancer products (such as chemotherapeutic agents, targeted therapies, immunotherapies, and novel cancer drugs) refers to their ability to affect cancer cells preferentially over normal, healthy cells. High selectivity is important because it can lead to better patient outcomes by reducing side effects and minimizing damage to normal tissues.

Achieving high selectivity in cancer treatment is crucial for improving patient outcomes. It relies on pinpointing molecular differences between cancerous and normal cells, designing drugs or delivery systems that exploit these differences, and overcoming intrinsic challenges like tumor heterogeneity and resistance

Factors that affect selectivity:
1. Ability of Cancer cells to preferentially absorb a product/drug
-EPR-enhanced permeability and retention of cancer cells
-nanoparticle formations/carriers may target cancer cells over normal cells
-Liposomal formations. Also negatively/positively charged affects absorbtion

2. Product/drug effect may be different for normal vs cancer cells
- hypoxia
- transition metal content levels (iron/copper) change probability of fenton reaction.
- pH levels
- antiOxidant levels and defense levels

3. Bio-availability

- in-vivo, CRC, HCT116 - in-vitro, CRC, HCT116
eff↑, Guided by this mechanism, the specific cytotoxicity of ART toward CRC cells can be dramatically enhanced with the addition of aminolevulinic acid (ALA), a clinically used heme synthesis precursor, to increase heme levels
ROS↑, We found that artesunate significantly increased ROS levels (Figure 4f) in HCT116 cells
selectivity↑, In contrast, heme levels in normal cells and tissues are strictly controlled and maintained at lower levels, minimizing ART’s activation, which could possibly explain the specificity and low toxicity of ART.
TumCG↓, Strikingly, the combination of artesunate and ALA showed significant tumor growth delay in comparison to both the control and the artesunate or ALA single treatment groups
toxicity↓, Since both artesunate and ALA are clinically used and well-tolerated, (52) this combination has the potential to be safely applied to subsequent clinical testing
