| Berberine — Berberine is a protoberberine/isoquinoline alkaloid natural product found in plants such as Coptis, Berberis, and Phellodendron. It is a small-molecule phytochemical with pleiotropic metabolic, anti-inflammatory, and anticancer signaling effects rather than a single highly selective target profile. Its standard abbreviation is BBR. In oncology it is best classified as a multitarget natural-product lead compound and adjunct-sensitizer candidate, with strong preclinical evidence but no established standard anticancer regulatory use. Its translational profile is shaped by very low conventional oral bioavailability, extensive first-pass metabolism, broad tissue distribution, and substantial context dependence between cancer-cell pro-death effects and normal-cell cytoprotective redox effects. Primary mechanisms (ranked):
Bioavailability / PK relevance: Conventional oral berberine has poor systemic bioavailability, often cited as below 1% in animal studies, because of limited absorption, P-glycoprotein efflux, first-pass intestinal/hepatic metabolism, and self-aggregation. Human exposure is usually in the low ng/mL plasma range with conventional dosing, while multiple metabolites may contribute to activity. Tissue distribution can exceed plasma levels, but PK remains a major clinical translation constraint. In-vitro vs systemic exposure relevance: Many anticancer in-vitro studies use roughly 10–100 µM, commonly around 20–50 µM, which usually exceeds readily achievable conventional plasma exposure after standard oral dosing. Therefore, direct translation of cell-culture potency to systemic monotherapy expectations is limited unless local gut exposure, tissue accumulation, metabolite contribution, formulation enhancement, or combination use is specifically relevant. Clinical evidence status: Strong preclinical and mechanistic evidence; limited early human oncology/chemoprevention evidence; no established phase III anticancer efficacy standard and no mainstream regulatory approval as an anticancer drug. Current clinical relevance is best viewed as investigational and adjunct-oriented rather than proven standalone oncology therapy. Berberine is a chemical found in some plants like European barberry, goldenseal, goldthread, Oregon grape, phellodendron, and tree turmeric. Berberine is a bitter-tasting and yellow-colored chemical.Coptis (commonly referring to Coptidis Rhizoma, a traditional Chinese medicinal herb) contains bioactive alkaloids (most notably berberine and coptisine) that have been studied for their pharmacological effects—including their influence on reactive oxygen species (ROS) and related pathways. – Berberine is known for its relatively low oral bioavailability, often cited at less than 1%. This low bioavailability is mainly due to poor intestinal absorption and active efflux by transport proteins such as P-glycoprotein. – Despite the low bioavailability, berberine is still pharmacologically active, and its metabolites may also contribute to its overall effects. • Effective Dosage in Studies – Many clinical trials or preclinical studies use dosages in the range of 500 to 1500 mg per day, typically administered in divided doses. – Therefore, to obtain a bioactive dose of berberine, supplementation in a standardized extract form is necessary. -IC50 in cancer cell lines: Approximately 10–100 µM (commonly around 20–50 µM in many models) -IC50 in normal cell lines: Generally higher (often above 100 µM), although this can vary with cell type - In vivo studies: Dosing regimens in animal models generally range from about 50 to 200 mg/kg - very effective AChE inhibitor (Alzheimers) - Berberine may enhance the effects of blood-thinning medications like warfarin and aspirin. -Note half-life reports vary 2.5-90hrs?. -low solubility of apigenin in water : BioAv Pathways: - induce ROS production - ROS↑ related: MMP↓(ΔΨm), ER Stress↑, Ca+2↑, Cyt‑c↑, Caspases↑, DNA damage↑, UPR↑, cl-PARP↑, HSP↓ - Lowers AntiOxidant defense in Cancer Cells: NRF2↓, GSH↓ - Raises AntiOxidant defense in Normal Cells: NRF2↑, SOD↑, GSH↑, Catalase↑, - lowers Inflammation : NF-kB↓, COX2↓, p38↓, Pro-Inflammatory Cytokines : IL-1β↓, TNF-α↓, IL-6↓, IL-8↓ - PI3K/AKT(Inhibition), JAK/STATs, Wnt/β-catenin, AMPK, MAPK/ERK, and JNK. - inhibit Growth/Metastases : , MMPs↓, MMP2↓, MMP9↓, IGF-1↓, uPA↓, VEGF↓, ROCK1↓, FAK↓, RhoA↓, NF-κB↓, CXCR4↓, TGF-β↓, α-SMA↓, ERK↓ - reactivate genes thereby inhibiting cancer cell growth : HDAC↓, DNMT1↓, EZH2↓, P53↑, HSP↓ - cause Cell cycle arrest : TumCCA↑, cyclin D1↓, cyclin E↓, CDK2↓, CDK4↓, CDK6↓, - inhibits Migration/Invasion : TumCMig↓, TumCI↓, FAK↓, ERK↓, - inhibits glycolysis /Warburg Effect and ATP depletion : HIF-1α↓, PKM2↓, cMyc↓, GLUT1↓, LDH↓, LDHA↓, HK2↓, PFKs↓, PDKs↓, Glucose↓, GlucoseCon↓ - inhibits angiogenesis↓ : VEGF↓, HIF-1α↓, Notch↓, FGF↓, PDGF↓, EGFR↓, Integrins↓, - inhibits Cancer Stem Cells : CSC↓, Hh↓, GLi1↓, CD133↓, β-catenin↓, n-myc↓, sox2↓, notch2↓, nestin↓, OCT4↓, - Others: PI3K↓, AKT↓, JAK↓, STAT↓, Wnt↓, β-catenin↓, AMPK↓, α↓, ERK↓, JNK, - Synergies: chemo-sensitization, chemoProtective, RadioSensitizer, RadioProtective, Others(review target notes), Neuroprotective, Cognitive, Renoprotection, Hepatoprotective, CardioProtective, - Selectivity: Cancer Cells vs Normal Cells

| The MYC proto-oncogenes are among the most commonly activated proteins in human cancer. The oncogene c-myc, which is frequently over-expressed in cancer cells, is involved in the transactivation of most of the glycolytic enzymes including lactate dehydrogenase A (LDHA) and the glucose transporter GLUT1 [51,52]. Thus, c-myc activation is a likely candidate to promote the enhanced glucose uptake and lactate release in the proliferating cancer cell. The c-Myc oncogene is a ‘master regulator’ of both cellular growth and metabolism in transformed cells. -C-myc is a common oncogene that enhances aerobic glycolysis in the cancer cells by transcriptionally activating GLUT1, HK2, PKM2 and LDH-A Inhibitors (downregulate): Curcumin Resveratrol: downregulate c-Myc expression. Epigallocatechin Gallate (EGCG) Quercetin Berberine: decrease c-Myc expression and repress its transcriptional activity. |
