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):

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.
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.
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.
PI3K/Akt/mTOR/STAT3 modulation, more strongly supported for asiatic acid than for asiaticoside itself, with relevance to proliferation, survival, autophagy, and metastatic phenotype.
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.
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.

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
1	Neuroinflammation NF-κB cytokine axis	NF-κB↓, TNF-α↓, IL-1β↓	Reduced inflammatory signaling	Most defensible AD-relevant mechanism; not disease-specific.
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.

NRF2, nuclear factor erythroid 2-related factor 2: Click to Expand ⟱

Source: TCGA

Type: Antiapoptotic

Nrf2 is responsible for regulating an extensive panel of antioxidant enzymes involved in the detoxification and elimination of oxidative stress. Thought of as "Master Regulator" of antioxidant response.
-One way to estimate Nrf2 induction is through the expression of NQO1.
NQO1, the most potent inducer:
SFN 0.2 μM,
quercetin (2.5 μM),
curcumin (2.7 μM),
Silymarin (3.6 μM),
tamoxifen (5.9 μM),
genistein (6.2 μM ),
beta-carotene (7.2μM),
lutein (17 μM),
resveratrol (21 μM),
indol-3-carbinol (50 μM),
chlorophyll (250 μM),
alpha-cryptoxanthin (1.8 mM),
and zeaxanthin (2.2 mM)

1. Raising Nrf2 enhances the cell's antioxidant defenses and ↓ROS. This strategy is used to decrease chemo-radio side effects.
2. Downregulating Nrf2 lowers antioxidant defenses and ↑ROS. In cancer cells this leads to DNA damage, and cell death.
3. However there are some cases where increasing Nrf2 paradoxically causes an increase in ROS (cancer cells). Such as cases of Mitochondial overload, signal crosstalk, reductive stress

-In some cases, Nrf2 is overexpressed in cancer cells, which can lead to the activation of genes involved in cell proliferation, angiogenesis, and metastasis. This can contribute to the development of resistance to chemotherapy and targeted therapies.
-Increased Nrf2 expression: Lung, Breast, Colorectal, Prostrate.
Decreased Nrf2 expression: Skine, Liver, Pancreatic.
-Nrf2 is a cytoprotective transcription factor which demonstrated both a negative effect as well as a positive effect on cancer
- "promotes Nrf2 translocation from the cytoplasm to the nucleus," means facilitates the movement of Nrf2 into the nucleus, thereby enhancing the cell's antioxidant and cytoprotective responses. -Major regulator of Nrf2 activity in cells is the cytosolic inhibitor Keap1.

Nrf2 Inhibitors and Activators
Nrf2 Inhibitors: Brusatol, Luteolin, Trigonelline, VitC, Retinoic acid, Chrysin
Nrf2 Activators: SFN, OPZ EGCG, Resveratrol, DATS, CUR, CDDO, Api
- potent Nrf2 inducers from plants include sulforaphane, curcumin, EGCG, resveratrol, caffeic acid phenethyl ester, wasabi, cafestol and kahweol (coffee), cinnamon, ginger, garlic, lycopene, rosemany

Nrf2 plays dual roles in that it can protect normal tissues against oxidative damage and can act as an oncogenic protein in tumor tissue.
– In healthy tissues, NRF2 activation helps protect cells from oxidative damage and maintains cellular homeostasis.
– In many cancers, constitutive activation of NRF2 (often through mutations in NRF2 itself or loss-of-function mutations in KEAP1) leads to an enhanced antioxidant capacity.
– This upregulation can promote tumor cell survival by enabling cancer cells to thrive under oxidative stress, resist chemotherapeutic agents, and sustain metabolic reprogramming.
– Elevated NRF2 levels have been implicated in promoting tumor growth, metastasis, and resistance to therapy in various malignancies.
– High or sustained NRF2 activity is frequently associated with aggressive tumor phenotypes, poorer prognosis, and decreased overall survival in several cancer types.
– While its activation is essential for protecting normal cells from oxidative stress, aberrant or sustained NRF2 activation in tumor cells can lead to enhanced survival, therapeutic resistance, and tumor progression.

NRF2 inhibitors: (to decrease antioxidant defenses and increase cell death from ROS).
-Brusatol: most cited natural inhibitors of Nrf2.
-Luteolin: luteolin can reduce Nrf2 activity in specific cancer models and may enhance cell sensitivity to chemotherapy. However, luteolin is also known as an antioxidant, and its influence on Nrf2 can sometimes be context dependent.
-Apigenin: certain studies to down‑regulate Nrf2 in cancer cells: Dose and context dependent .
-Oridonin:
-Wogonin: although its effects might be cell‑ and dose‑specific.
- Withaferin A
