| 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) Pathways: - induce ROS production, iron dependent (affect both cancer and normal cells) - ROS↑ related: MMP↓(ΔΨm), ER Stress↑, UPR↑, GRP78↑, Ca+2↑, Cyt‑c↑, Caspases↑, DNA damage↑, cl-PARP↑, HSP↓, - Both Lowers (and raises) AntiOxidant defense in Cancer Cells: NRF2↓(contary), SOD↓, GSH↓ Catalase↓ GPx↓ - Small evidence of Raising AntiOxidant defense in Normal Cells: ROS↓(contary), NRF2↑, SOD↑(contary), GSH↑, Catalase↑, - lowers Inflammation : NF-kB↓, COX2↓, p38↓, Pro-Inflammatory Cytokines : NLRP3↓, TNF-α↓, IL-6↓, IL-8↓ - inhibit Growth/Metastases : TumMeta↓, TumCG↓, EMT↓, MMPs↓, MMP2↓, MMP9↓, TIMP2, IGF-1↓, uPA↓, VEGF↓, ROCK1↓, NF-κB↓, TGF-β↓, ERK↓ - cause Cell cycle arrest : TumCCA↑, cyclin D1↓, cyclin E↓, CDK2↓, CDK4↓, CDK6↓, - inhibits Migration/Invasion : TumCMig↓, TumCI↓, TNF-α↓, ERK↓, EMT↓, TOP1↓, - inhibits glycolysis /Warburg Effect and ATP depletion : HIF-1α↓, PKM2↓, cMyc↓, GLUT1↓, LDH↓, LDHA↓, HK2↓, ECAR↓, GRP78↑, GlucoseCon↓ - inhibits angiogenesis↓ : VEGF↓, HIF-1α↓, EGFR↓, Integrins↓, - some small indication of inhibiting Cancer Stem Cells : CSC↓, Hh↓, β-catenin↓, sox2↓, OCT4↓, - Others: PI3K↓, AKT↓, JAK↓, STAT↓, Wnt↓, β-catenin↓, AMPK, ERK↓, JNK, - Synergies: chemo-sensitization, RadioSensitizer, Others(review target notes), - Selectivity: Cancer Cells vs Normal Cells |

| The Warburg effect is a metabolic phenomenon in which cancer cells preferentially use glycolysis for energy production, even in the presence of oxygen. Targeting the pathways involved in the Warburg effect is a promising strategy for cancer treatment. The Warburg effect is always accompanied by a hypoxic condition, and activation of HIF-1a contributes to the Warburg effect through coordinated upregulation of glycolysis and downregulation of oxidative phosphorylation. Warburg effect (GLUT1, LDHA, HK2, and PKM2). Here are some of the key pathways and potential targets: Note: use database Filter to find inhibitors: Ex pick target HIF1α, and effect direction ↓ 1.Glycolysis Inhibitors:(2-DG, 3-BP) -HK2 Inhibitors: such as 2-deoxyglucose, can reduce glycolysis -PFK1 Inhibitors: such as PFK-158, can reduce glycolysis -PFKFB Inhibitors: -PKM2 Inhibitors: (Shikonin) -Can reduce glycolysis -LDH Inhibitors: (Gossypol, FX11) -Reducing the conversion of pyruvate to lactate. -Inhibiting the production of ATP and NADH. -GLUT1 Inhibitors: (phloretin, WZB117) -A key transporter involved in glucose uptake. -GLUT3 Inhibitors: -PDK1 Inhibitors: (dichloroacetate) - A key enzyme involved in the regulation of glycolysis. 2.Gluconeogenesis pathway: -FBP1 Activators: can increase gluconeogenesis -PEPCK1 Inhibitors: can reduce gluconeogenesis 3.Pentose phosphate pathway: -G6PD Inhibitors: can reduce the pentose phosphate pathway 4.Mitochondrial metabolism: -MPC1 Inhibitors: can reduce mitochondrial metabolism and inhibit cancer -SDH Inhibitors: can reduce mitochondrial metabolism and inhibit cancer cell growth. 5.Hypoxia-inducible factor 1 alpha (HIF1α) pathway: -HIF1α inhibitors: (PX-478,Shikonin) -Reduce expression of glycolytic genes and inhibit cancer cell growth. 6.AMP-activated protein kinase (AMPK) pathway: -AMPK activators: (metformin,AICAR,berberine) -Can increase AMPK activity and inhibit cancer cell growth. 7.mTOR pathway: -mTOR inhibitors:(rapamycin,everolimus) -Can reduce mTOR activity and inhibit cancer cell growth. |
