Features:

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):

  1. AMPK-centered metabolic stress with mitochondrial dysfunction, ATP depletion, and apoptosis/autophagy induction
  2. Suppression of aerobic glycolysis and hypoxia signaling, including HIF-1α, GLUT1, HK2, LDHA, and PKM2-linked tumor metabolism
  3. Anti-proliferative cell-cycle control with cyclin/CDK suppression and tumor suppressor reactivation
  4. Inhibition of PI3K/AKT, MAPK/ERK, JAK/STAT, and NF-κB inflammatory-survival signaling
  5. Anti-metastatic and anti-EMT activity via Wnt/β-catenin, TGF-β/Smad, FAK/RhoA/ROCK, MMPs, and CXCR4-related programs
  6. Pro-oxidant mitochondrial ROS elevation and ER-stress/caspase signaling in many cancer models, with opposite antioxidant/NRF2-supportive effects in some normal-cell and non-cancer settings
  7. Context-dependent chemosensitization and radiosensitization, including effects on hypoxia signaling and DNA-repair competence
  8. Emerging ferroptosis-related activity in some tumor models, but not a universal dominant mechanism across berberine biology

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.

MAPK, mitogen-activated protein kinase: Click to Expand ⟱
Source: CGL-CS
Type:
Mitogen-activated protein kinases (MAPKs) are a group of proteins involved in transmitting signals from the cell surface to the nucleus, playing a crucial role in various cellular processes, including growth, differentiation, and apoptosis (programmed cell death).

MAPK Pathways: The MAPK family includes several pathways, the most notable being:
1.ERK (Extracellular signal-Regulated Kinase): Often associated with cell proliferation and survival.
2.JNK (c-Jun N-terminal Kinase): Typically involved in stress responses and apoptosis.
3.p38 MAPK: Associated with inflammatory responses and apoptosis.

Inhibitors: Targeting the MAPK pathway has become a strategy in cancer therapy. For example, BRAF inhibitors (like vemurafenib) are used in treating melanoma with BRAF mutations.
Altered Expression Levels:
Overexpression: Many cancers exhibit overexpression of MAPK pathway components, such as RAS, BRAF, and MEK. This overexpression can lead to increased signaling activity, promoting cell proliferation and survival.
Downregulation: In some cases, negative regulators of the MAPK pathway (e.g., MAPK phosphatases) may be downregulated, leading to enhanced MAPK signaling.
The expression levels of MAPK pathway components can serve as biomarkers for cancer diagnosis, prognosis, and treatment response. For example, high levels of phosphorylated ERK (p-ERK) may indicate active MAPK signaling and poor prognosis in certain cancers.

Numerous reports indicate that the MAPK pathway plays a major role in tumor progression and invasion, while inhibition of MAPK signaling reduces invasion.
