| Betulinic acid "buh-TOO-li-nik acid" is a natural compound with antiretroviral, anti malarial, anti-inflammatory and anticancer properties. It is found in the bark of several plants, such as white birch, ber tree and rosemary, and has a complex mode of action against tumor cells. -Betulinic acid is a naturally occurring pentacyclic triterpenoid -vitro concentrations range from 1–100 µM, in vivo studies in rodents have generally used doses from 10–100 mg/kg Precursor: Betulin, via oxidation at C-28 Lipophilicity: High (poor aqueous solubility) -half-life reports vary 3-5 hrs?. Reported half-life varies by formulation and species; several studies report multi-hour systemic persistence. BioAv -hydrophobic molecule with relatively poor water solubility. Main Cancer action -Direct mitochondrial targeting in cancer cells -Minimal effect on normal cells Key pathways -Mitochondrial membrane permeabilization -ROS-mediated apoptosis -Caspase-independent death Chemo relevance: Generally compatible, Not a redox buffer Pathways: - often induce ROS production - ROS↑ related: MMP↓(ΔΨm), ER Stress↑, UPR↑, GRP78↑, Ca+2↑, Cyt‑c↑, Caspases↑, DNA damage↑, cl-PARP↑, HSP↓ - Lowers AntiOxidant defense in Cancer Cells(Often associated with reduced redox buffering capacity in tumor cells (e.g., GSH depletion); NRF2 direction model-dependent.): NRF2↓, SOD↓, GSH↓ - May Raise AntiOxidant defense in Normal Cells: NRF2↑, SOD↑, GSH↑, Catalase↑ Reports suggest relative sparing of normal cells and preservation of antioxidant capacity in some models - lowers Inflammation : NF-kB↓(typ), COX2↓, p38↓ (context-dependent; often stress-activated), Pro-Inflammatory Cytokines : IL-1β↓, TNF-α↓, IL-6↓, IL-8↓ - inhibit Growth/Metastases : , MMPs↓, MMP2↓, MMP9↓, TIMP2, IGF-1↓, VEGF↓, ROCK1↓, FAK↓, NF-κB↓, TGF-β↓, α-SMA↓, ERK↓ - reactivate genes thereby inhibiting cancer cell growth : P53↑, HSP↓(model-dependent), Sp proteins↓, - cause Cell cycle arrest : TumCCA↑, cyclin D1↓, CDK2↓, CDK4↓, - inhibits Migration/Invasion : TumCMig↓, TumCI↓, FAK↓, ERK↓, EMT↓, TOP1↓, - inhibits glycolysis (secondary to mitochondrial stress) ATP depletion : HIF-1α↓, PKM2↓, cMyc↓, GLUT1↓, LDH↓, LDHA↓, HK2↓, PFKs↓, PDKs↓, HK2↓, ECAR↓, GRP78↑(ER stress), GlucoseCon↓ - inhibits angiogenesis↓ : VEGF↓, HIF-1α↓, EGFR↓, - inhibits Cancer Stem Cells in some studies : CSC↓, GLi1↓, β-catenin↓, OCT4↓, - Others: PI3K↓(typ), AKT↓(typ), JAK↓, STAT↓, β-catenin↓, AMPK↓(AMPK is often activated during metabolic stress), ERK↓, JNK, - Synergies: chemo-sensitization, chemoProtective, RadioSensitizer, Others(review target notes), Neuroprotective, Cognitive, Renoprotection, Hepatoprotective, CardioProtective, - Selectivity: Cancer Cells vs Normal Cells

| A signal protein produced by many cells that stimulates the formation of blood vessels.
Vascular endothelial growth factor (VEGF) is a signal protein that plays a crucial role in angiogenesis, the process by which new blood vessels form from existing ones. This process is vital for normal physiological functions, such as wound healing and the menstrual cycle, but it is also a key factor in the growth and spread of tumors in cancer. Because of its significant role in tumor growth and progression, VEGF has become a target for cancer therapies. Anti-VEGF therapies, such as monoclonal antibodies (e.g., bevacizumab) and small molecule inhibitors, aim to inhibit the action of VEGF, thereby reducing blood supply to tumors and limiting their growth. These therapies have been used in various types of cancer, including colorectal, lung, and breast cancer. |
