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)

PKM2, Pyruvate Kinase, Muscle 2: Click to Expand ⟱
Source:
Type: enzyme
PKM2 (Pyruvate Kinase, Muscle 2) is an enzyme that plays a crucial role in glycolysis, the process by which cells convert glucose into energy. PKM2 is a key regulatory enzyme in the glycolytic pathway, and it is primarily expressed in various tissues, including muscle, brain, and cancer cells.
-C-myc is a common oncogene that enhances aerobic glycolysis in the cancer cells by transcriptionally activating GLUT1, HK2, PKM2 and LDH-A
-PKM2 has been shown to be overexpressed in many types of tumors, including breast, lung, and colon cancer. This overexpression may contribute to the development and progression of cancer by promoting glycolysis and energy production in cancer cells.
-inhibition of PKM2 may cause ATP depletion and inhibiting glycolysis.
-PK exists in four isoforms: PKM1, PKM2, PKR, and PKL
-PKM2 plays a role in the regulation of glucose metabolism in diabetes.
-PKM2 is involved in the regulation of cell proliferation, apoptosis, and autophagy.
– Pyruvate kinase catalyzes the final, rate-limiting step of glycolysis, converting phosphoenolpyruvate (PEP) to pyruvate with the production of ATP.
– The PKM2 isoform is uniquely regulated and can exist in both highly active tetrameric and less active dimeric forms.
– Cancer cells often favor the dimeric form of PKM2 to slow pyruvate production, thereby accumulating upstream glycolytic intermediates that can be diverted into anabolic pathways to support cell growth and proliferation.
– Under low oxygen conditions, cancer cells rely on altered metabolic pathways in which PKM2 is a key player. – The shift to aerobic glycolysis (Warburg effect) orchestrated in part by PKM2 helps tumor cells survive and grow in hypoxic conditions.

– Elevated expression of PKM2 is frequently observed in many cancer types, including lung, breast, colorectal, and pancreatic cancers.
– High levels of PKM2 are often correlated with enhanced tumor aggressiveness, poor differentiation, and advanced clinical stage.

PKM2 in carcinogenesis and oncotherapy

Inhibitors of PKM2:
-Shikonin, Resveratrol, Baicalein, EGCG, Apigenin, Curcumin, Ursolic Acid, Citrate (best known as an allosteric inhibitor of phosphofructokinase-1 (PFK-1), a key rate-limiting enzyme in glycolysis) potential to directly inhibit or modulate PKM2 is less well established
