Centella asiatica / Gotu kola → asiaticoside — Centella asiatica is a medicinal botanical extract source, and asiaticoside is one of its major pentacyclic triterpenoid saponin marker constituents. The formal classification is botanical standardized extract / natural-product triterpenoid saponin modality, not an approved anticancer drug. The principal active family includes asiaticoside, madecassoside, asiatic acid, and madecassic acid; asiaticoside can also be metabolically linked to asiatic acid. Asiaticoside as the main active marker, with Centella asiatica standardized extract as the primary product.

Primary mechanisms (ranked):

  1. NF-κB and inflammatory cytokine suppression, especially reduced TNF-α, IL-1β, IL-6, COX-2/PGE2, and downstream survival signaling in inflammatory and tumor models.
  2. Mitochondrial apoptosis induction in cancer cells, with Bax:Bcl-2 shift, MMP loss, caspase-9 activation, caspase-3 activation, and p53/p21-associated cell-cycle arrest reported in preclinical models.
  3. Anti-migration and anti-EMT effects, including suppression of p65/NF-κB-linked EMT, YAP1/VEGFA signaling, invasion, and radiation-induced migration in selected cancer-cell systems.
  4. PI3K/Akt/mTOR/STAT3 modulation, more strongly supported for asiatic acid than for asiaticoside itself, with relevance to proliferation, survival, autophagy, and metastatic phenotype.
  5. TGF-β/collagen/fibroblast and wound-repair axis activation in normal tissue contexts; beneficial for repair but mechanistically ambiguous in cancer because fibrosis and angiogenesis can be tumor-context dependent.
  6. Oxidative-stress modulation, generally antioxidant and cytoprotective in normal cells; ROS/NRF2 effects are secondary and context-dependent rather than the core anticancer mechanism.

Bioavailability / PK relevance: Oral translation is constrained by variable extract composition, limited dissolution and bioavailability of triterpenes, metabolism of glycosides to aglycones, and formulation dependence. Standardized extracts such as ECa 233 and aqueous Centella asiatica products have human phase-1 PK data, but systemic exposure is still not equivalent to common high-concentration in-vitro cancer experiments.

In-vitro vs systemic exposure relevance: Cancer-cell studies commonly use micromolar asiaticoside or asiatic-acid exposures that may exceed or not cleanly map onto achievable plasma exposure after oral botanical dosing. Topical and local tissue uses are more plausible for skin/wound biology than systemic anticancer effects. For cancer translation, the entry should be treated as concentration- and formulation-dependent.

Clinical evidence status: Cancer relevance is weak / preclinical only, with no established oncology indication. Human evidence is stronger for wound healing, venous/skin-related uses, and early cognitive/AD-oriented safety or PK studies than for cancer treatment. AD relevance is possible / early clinical, with phase-1 target-engagement work in mild cognitive impairment or mild Alzheimer’s disease, but no proven disease-modifying efficacy.

1 NF-κB inflammatory survival axis NF-κB↓, p65↓, TNF-α↓, IL-1β↓ NF-κB↓, inflammatory cytokines↓ R,G Anti-inflammatory and anti-survival signaling Most central cross-context mechanism; supports anticancer, neuroinflammatory, and wound-healing interpretations but is not cancer-specific.
2 Mitochondrial apoptosis MMP↓, Bax:Bcl-2↑, caspase-9↑, caspase-3↑ Apoptosis↔ or ↓ in injury models (context-dependent) G Intrinsic apoptotic priming in tumor models Preclinical cancer-cell effect; selectivity depends strongly on dose, cell line, and compound form.
3 Cell-cycle checkpoint and p53 axis p53↑, p21↑, cyclin D1↓, CDK4↓ Cell-cycle stress↔ (context-dependent) G Growth arrest and reduced proliferation cytostatic activity; best treated as model-dependent rather than universal.
4 EMT migration invasion axis Migration↓, invasion↓, EMT↓, YAP1/VEGFA↓, p65↓ Repair migration↑ in wound contexts (context-dependent) G Reduced metastatic phenotype in selected models Important because Centella can promote normal wound repair while suppressing tumor-cell invasion in some systems; interpretation is tissue-context dependent.
5 PI3K Akt mTOR STAT3 survival axis PI3K/Akt↓, mTOR↓, STAT3↓ (mainly asiatic acid) Mixed cytoprotection or survival signaling↔ R,G Reduced survival, proliferation, and metastatic signaling Better supported for asiatic acid than asiaticoside; include as related triterpene-family mechanism rather than asiaticoside-only claim.
6 Autophagy axis LC3-II↑, autophagy↑ (model-dependent) Autophagy↔ or ↑ (context-dependent) G Stress adaptation or autophagic cell death Direction and therapeutic meaning are model-dependent; can be pro-death or protective depending on tumor context.

11 Clinical Translation Constraint High in-vitro exposure required (often) Rare hepatotoxicity risk; product variability G Limits systemic anticancer translation Bioavailability, formulation, extract standardization, dose limitation, and weak oncology trial evidence are the main constraints.

AD relevance: Possible / preclinical. Interest is mainly through neuroinflammation, oxidative stress, mitochondrial protection, and general neuroprotective mechanisms.

Alzheimer’s disease relevance: Centella asiatica / Gotu kola has a plausible but unproven AD-oriented profile. The strongest rationale is not direct amyloid clearance as an established clinical effect, but combined modulation of neuroinflammation, oxidative stress, mitochondrial metabolism, synaptic or neuronal viability markers, and vascular/microcirculatory support. Human evidence is early: phase-1 PK/safety and target-engagement studies exist in older adults with mild cognitive impairment or mild Alzheimer’s disease, but efficacy remains unproven.

Clinical evidence status: AD / cognition evidence is preclinical plus small human and phase-1 clinical work. Early translational / investigational rather than established therapy.

Cancer relevance: Weak / preclinical.

AD-Oriented Mechanistic Profile

Rank Pathway / Axis Modulation Primary Effect Notes / Interpretation

2 Mitochondrial metabolism neuronal viability Mitochondrial function↑, metabolic stress↓ Neuronal bioenergetic support Central to current target-engagement rationale in cognitive impairment studies.
3 Oxidative stress DNA oxidation axis Oxidative stress↓, 8OHdG↓ (candidate marker) Reduced oxidative injury Relevant to trial biomarker strategy; clinical disease modification unproven.
4 Synaptic memory and neuronal morphology axis Learning and memory markers↑ (model-dependent) Cognitive-support signal in animals Preclinical support is stronger than human efficacy evidence.
5 Amyloid-associated pathology β-amyloid stress↓ (model-dependent) Reduced amyloid-model metabolic disturbance model-dependent, not as proven anti-amyloid clinical activity.
6 Clinical Translation Constraint Bioavailability↔, extract variability↑, evidence limitation↑ Limits AD clinical interpretation Current status is investigational; formulation, heavy-metal quality, dose, and trial endpoints matter.


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.
